B2B SaaS UK

Company Location: London

Type: Full-time

Role Overview

Accessible rail travel depends on systems that work reliably in live environments.

Our Passenger Assistance platform turns passenger assistance requests into coordinated action inside live rail operations.

We’re hiring a QA Engineer to lead manual quality and release confidence across our UK and Global web and mobile platforms.

Strategic Context

Transreport exists to remove structural barriers in rail travel. Our vision is that everyone has access to travel everywhere.

We operate across the UK, Japan, and the EU and have supported over 10 million assistance requests for more than 1 million users. We are a Series A company recognised with a King’s Award.

Because we operate in live, safety-critical environments, quality discipline is fundamental, not optional. As the platform grows in complexity across markets, this role ensures that reliability remains uncompromised.

Outcomes & Impact

Within 6 months, you will:

• Own manual QA for at least one active product stream.
• Embed earlier into refinement and design to strengthen acceptance criteria.
• Improve regression structure and reduce escaped defects.
• Bring clarity and consistency to our TestRail coverage.
• Act as a trusted release partner for Engineering and Product.

Within 12 months, you will:

• Confidently rotate across UK and Global teams.

• Identify recurring quality risks and drive preventative improvements.
• Raise the overall standard of release confidence across web and mobile.

Tasks

Responsibilities

• Execute & Manage Testing: Own the manual testing lifecycle for web (Vue.js/Rails) and mobile (Native Swift/Kotlin) applications.
• Shift Left: Participate in design and requirements sessions, clarifying how A/Cs are tested before a single line of code is written.
• Test Case Management: maintain and expand our TestRail repository. You will decide what needs a manual pass and what candidates should be handed off to SDETs for automation.
• Release Confidence: Act as the final gatekeeper for releases, conducting smoke tests and regression passes to ensure high reliability for our public-facing and B2B users.
• Cross-Platform QA: Verify consistency across our web dashboard and mobile apps, ensuring data syncs correctly between the Rails backend and the client devices.

The Tech Environment:

• Management: TestRail, Jira.
• Web: Vue.js (Frontend), Ruby on Rails (Backend).
• Mobile: Native Swift (iOS) & Native Kotlin (Android) as well as React Native.
• Note: While our stack includes RSpec and Vue wrapper, this is a functional QA role. You are not expected to write code, but you should be comfortable navigating a technical environment.

Requirements

Requirements

Must Haves

• Experience: 3+ years of experience in manual QA for web and mobile applications.

We’re looking for a curious, rigorous, problem-hungry platform engineer (who codes!) to carry the ball as we bring Ashby to the big leagues. Ashby builds software that lets talent teams build an efficient, delightful, respectful hiring process. Similarly, you’re an engineer who wants to build a “paved road” that excellent engineering teams can safely take to the moon and back.

We have notable customers like Notion, Linear, Shopify, and Snowflake. Our growth and retention metrics are best-in-class among our peers: we have tens of millions in ARR, growing >100% year over year, over 2500 customers, very low churn, and many years of runway. We’ll share more details once we meet, but you now probably have a good idea as to why we’re hiring for this role .

We’ve listed this role twice: as a Platform Engineer and Site Reliability Engineer - our team does both, and we are open to candidates who lean towards one or the other.

About the role and how we work Hi I’m Colin, Head of EMEA Engineering. I’ve spent a number of years leading engineering teams in startups, and that has always included being close to infrastructure teams - no matter what name they’ve worn (SRE, infrastructure, platform, etc). I’ve got my hands dirty building the initial infrastructure for startups and know the value a talented infrastructure engineer brings. The rigour, the discipline, the peace and quiet when everything just hums along.

Our infrastructure is in a good place for now. Nothing is static. Ashby continues to grow rapidly, putting strain on our existing infrastructure. We’re always looking to give our customers more powerful hiring software, and building new product features often requires new pieces of infrastructure.

Having herded plenty of snowflakeservers in the past, I’ve learned there’s a better way. I (and Ashby) place a lot of value on infrastructure-as-code. As a Platform Engineer at Ashby, you’ll get to dive into scaling problems, add new capabilities to our platform, and think about how our entire team interacts with infrastructure. All our own engineers own their projects end-to-end and ship with minimal oversight. We don’t put roadblocks to ensure security when common sense will do and we don’t build processes like change management boards around the lowest common denominator. But with great power comes great responsibility: we handle personal and confidential data about some of the biggest decisions we ever make at work. As we grow, more and bigger customers rely on us to be reliable and secure and how we operate internally will need to evolve.

We’re at an inflection point where our ability to scale and deliver a seamless experience has a make-or-break impact - we have some of the fastest growing companies using our platform every day to hire hundreds of people per month. We need someone like you to make good decisions, debug thorny issues, and build us a future-proof platform that can withstand this scale. Our small but mighty infrastructure team has set up a secure and simple environment (we don’t believe in spinning up a new service unless necessary!) for our growing product team to build in. That’s where you come in: you, too, will own projects end-to-end and have an impact on core parts of the Ashby developer and user experience. For instance, you could work on:

• Optimize our homegrown ultra-dynamic recruiting DSL-to-SQL compiler, and create tools to help developers do so
• Create automated guardrails for the security and privacy of our customer data
• Help our developers ship features fast through canary deploys, gradual rollouts and feature flags, while keeping complexity manageable and reducing downtime
• Work with the business and the engineering team to define SLOs and implement the corresponding SLIs.
• Ensure all communication with external services supports retries and circuit-breakers.
• Implement the infrastructure to support an event-driven architecture and data warehouse.

We’re looking for someone who can build systems that an engineer would like to work with: mature and boring but open-minded and approachable. We have to balance reliability with flexibility. Software and its availability are now mission critical to almost every working professional. To be in an SRE in today’s world, you have to be extremely comfortable evaluating risk, those you take and those others take.

Why you should or shouldn’t apply You should apply if:

• You never stop. You get weirdly obsessed about a problem that doesn’t yet make sense, turn it every which way in your head until the explanation dawns. You’ll search every rock, inventory every clue, hunt every mismatch. We do that too - together we’ll be armed with state-of-the-art monitoring tools and an impressive amount of data, and join you in the adventure.
• You don’t take shortcuts. You’re speaking up for the future user, the edge case, the doomsday design. You know product engineers want to build it with you, and see them as allies, where you give them the power and knowledge to access greater things.
• You’re someone who cares about what you do and the team you do it with, and want to work with others who do as well. You’ll be on interview panels choosing your next colleagues, and you’ll take that seriously. You only want to work with people who make you better, and want to make you better.
• You’ve built infrastructure at a slightly later stage than Ashby is at - you know how to deal with millions of data points, have seen great (or not great) infrastructure make or break customer experience, and have automated everything from provisioning to monitoring and release process.
• You’re a Swiss army knife (all nationalities welcome). You’ll get every hard problem the company faces. You’ll get to do infrastructure updates, security enforcements, database optimization, Kubernetes debugging, and digging through Typescript traces figuring out what doesn’t work. You probably don’t feel like an expert at at least some of that and that appeals to you.

All that makes for a pretty specific kind of role, and the job isn’t to everyone’s tastes! You should not apply if:

• You don’t want to make your own decisions on what is the best paved road to build for Ashby, and expect a lead or manager to make the final call on that. Our leads (and managers) give ample commentary and feedback on technical decisions and how they’re made, but you ship what you want to build and are accountable for it.
• You hate SQL. We have a lot of features built around making the best out of data, and our platform engineers also sometimes dive into a gnarly report or advise engineers on a more performant data model to use.
• You don’t want to code. Our SREs are some of our best software engineers and they are just as responsible for the application as the other engineering teams - albeit at a platform level. Reviewing code and submitting code changes will be part of your day to day.
• Your primary mode of communicating best practices to engineers is live meetings. We’re a very async culture and written communication (and code) is how changes get made. As an Ashby SRE, you will need to share new tooling and best practices with engineers faster than your next meeting opportunity will take you.
• You’ve never delivered a project, on your own, without someone prodding you for updates. We have no project or delivery managers to fill your calendar with busy work, but the flip side is you have to do your project management, seek the help you need to get unstuck and cut scope when it’s worthwhile.

Technology Stack We share our tech stack with the caveat that we don’t require previous experience in it: TypeScript (frontend & backend), Node.js, React, Apollo GraphQL, Postgres, Redis.

We use Datadog and Sentry on 100% cloud-based (AWS) infra. We take developer experience and reliability seriously: all engineers are on call in a follow-the-sun model, and everyone contributes to developer tooling.

What We’re Building As engineers, we are used to tooling that makes us better at what we do. When we started Ashby, we saw the opposite with Talent Acquisition software. Recruiting teams were leveling up how they did their work, but instead of software meeting this new standard, it held them back.

Scheduling a final round is an excellent example. Recruiting teams wanted to schedule candidates faster, track interviewer preparation and quality, and do it with half the headcount. A recruiter needed to manually collect availability from the candidate, identify qualified interviewers, perform “Calendar Tetris” to find who is available to interview the candidate, schedule on the earliest date possible, and make any last-minute adjustments as availability changed. They must do this while considering the interview load on each individual and whether interviewers need to be trained and shadowing others. TA software didn’t help.

Introduction

We’re looking for a Senior Software Engineer for one of our CMS product teams, working from the UK, to help us shape the future of Optimizely’s products and offerings. We’re at the top of industry analyst ratings and pushing to take both the PaaS and SaaS versions of our CMS further. A big part of that push is Opal, our always on AI workforce that improves productivity for content teams. Building on that capability is one of the things that makes this moment particularly interesting. Our engineers have been working on our CMS for years, many of them because they genuinely love it, and they’re eager to take it to the next level. This is your opportunity to join them.

About The Team

You’d join a group of teams with many senior engineers who have deep product knowledge and diverse technical backgrounds. Personal and cultural fit matters as much as skills and experience here. The team collaborates closely, both remotely and in person, with a culture built around trust and open communication. We have an office in London, and if you’re based there, we’d expect you to work from the office a few days per week. If you’re elsewhere in the UK, we fully support remote work.

We care about work life balance in practice, not just on paper. We work across time zones but respect local working hours, family commitments, and your physical and mental health. There are occasions where a critical production issue or urgent release requires work outside normal hours, but that is the exception, not the norm. Many of us have been here a long time. That’s not inertia, it’s because the work stays interesting and the environment is healthy.

What You’d Do

• Design, implement, and document software solutions that are simple, secure, scalable, and maintainable.
• Own the operational excellence of your domain, including instrumentation, monitoring and alerting.
• Ensure product quality through thorough automated testing.
• Drive delivery of complex features end to end, working across team boundaries when needed.
• Contribute to architecture and design discussions within your team and across teams, communicating decisions through design docs and knowledge sharing forums.
• Participate in project planning, requirements gathering, design, and task refinement.
• Handle incidents and assist our support organisation when they need engineering expertise on customer cases.
• Bring customer perspective into technical decisions, understanding how the product is used in practice.
• Mentor other engineers and share knowledge across the team.
• Participate in hiring and help grow a diverse engineering organisation.

What We’re Looking For

We value personal and cultural fit as much as technical skill. You are self motivated, enjoy collaborating to find the right solution, and you think about architecture, development cost, and long term ownership when making decisions. You’re comfortable working through ambiguity, can articulate trade offs clearly, and leave projects in a state where someone else can pick them up.

Must have:

• Typically 8+ years of professional experience with modern software development practices, though we recognise some people get there faster.
• Strong software design and engineering fundamentals, including object oriented analysis and design.
• Solid experience with C# and .NET, and with React on the frontend.
• Hands on experience with CMS platforms, content modelling, or digital experience tooling. You understand the domain and the problems content teams face.
• Experience building and operating cloud based software.
• Already using AI tools, coding assistants, and potentially agents as part of your daily workflow to improve both quality and speed.
• Comfortable working in an agile environment alongside designers, product managers, and other stakeholders.
• Good communicator who enjoys solving problems together with others.

Good to have:

• Experience with Optimizely CMS or other CMS/DXP platforms.
• NET Core MVC.
• SQL (particularly MS SQL).
• Containers and container orchestration.
• HTTP APIs, REST services, or GraphQL.
• Experience building large, modular applications with continuous delivery.
• A degree in Computer Science or equivalent. We care more about what you can do than what’s on your diploma.

Optimizely is committed to a diverse and inclusive workplace. Optimizely is an equal opportunity employer and does not discriminate on the basis of race, national origin, gender, gender identity, sexual orientation, protected veteran status, disability, age, or other legally protected status.
