Security Clearance

You must be eligible for full security clearance. For more information and guidance please visit : https://www.gov.uk/government/publications/united-kingdom-security-vetting-clearance-levels

What you’ll be doing:

Just to be upfront, this is not a pure front-end developer role. While we are looking for someone who’s “happy place” is building beautiful front ends, this person would need to be open to working on other parts of the stack. We’re a team of T-shaped people with broad competencies, so versatility is part of our culture. You don’t need to be an expert on everything. Just be comfortable with new challenges.

With that in mind, as a Senior Full Stack Developer (with front-end focus), you will:

Build solutions to problems (especially with a heavy front-end focus)

Design solutions (in conjunction with Product Managers and/or other colleagues)

Help colleagues facing issues with front-end development

More specifically, you will be heavily involved in app development using Flutter, in addition to web portal development.

Day-to-day life on the Product Development team looks like the following:

Most of your time will be spent designing and building solutions

For our tech stack, we use:

Django/Django REST Framework/Postgres for backend,

Angular for our web application,

Ionic/Angular for our apps (and we’re now moving to Flutter)

AWS ECS/ECR, Aurora and Lambda

For design, it’s quick brainstorming, a bit of analysis, sketching on paper or Figma, and/or jotting down a short design doc in Google Docs

A chunk of time is spent on understanding issues, users and our platform. This includes talking to ops colleagues. We take turns answering ops support requests

It’s fast paced. We’re light on overhead and don’t outsource quality to a QA team. Quality, maintainability and security start at the design stage and are everyone’s responsibility.

We run 2-week sprints. Each day starts with a daily 10-minute standup and then it varies a lot from there. The issues vary from sprint-to-sprint. It’s typically very user focused, but we do make time each quarter to do unsexy important stuff (refactor, pay down technical debt, database upgrades, etc).

It’s not a solo effort. While we maximise the time you must put your head down and get on with cracking a problem, we grab each other for help every day. And we do peer review of design and code, while building and deploying to production regularly

If you like having a holistic view of the product (from idea to release to growth), rather than being highly specialised in one niche, you’ll probably enjoy this role.

What we’re looking for:

General characteristics

You like solving real problems. When you make something, you make it to solve someone’s issue. You understand the issue and the person facing it. You put in a bit of extra effort to make it a good experience for the user

Uncertainty is a fun problem to figure out, rather than an annoying headache. When you don’t know the answer, you try something. You experiment. You dig.

You’re a clear concise communicator. When writing or speaking, you know which details to prioritise

KISS is important to you. You have an instinct for when a solution is too complicated for the problem

You know how to learn and skill up. When faced with a novel skill area, you can self- critique your level and push yourself to improve

You reside in the UK or the EU

If you don’t live near Oxford, you are able to travel and work in our office in Oxford for a few days each quarter

Specific characteristics for this role

Taken multiple features from idea to release to growth

Having spent meaningful time as part of different teams (we’d prefer at least 6 years as a developer)

Deep front-end experience, including responsive design

Built front ends or apps for consumer facing businesses

Design sense for UX/UI. Not just writing code. May have done wireframes before. Can look at an interface and tell if it is terrible or not

Ideally some experience working on backend (e.g. building APIs, database design, etc)

Some experience with CI/CD or deployments in general

Ideally, some experience in an agency (for consumer facing apps) and/or early-stage consumer facing startup

Ideally experience with mobile app development

Senior Full Stack Developer (front-end focus)
