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

Your background
(Nice to haves)
Hybrid working role based in our London offices (SE1): 3 days in the office, 2 days from home per week.
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
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.

Our mission is to change this.
