Quick facts

Team: Engineering

Reports to: Engineering Team Lead

Location: Remote, UK or abroad, with a few hours of daily UK overlap

Contract: Full time, permanent

Salary: £45,000 to £60,000, plus share options

Start date: As soon as we find the right person

Why this role exists

Driftrock's product runs on a pragmatic Elixir and Phoenix LiveView stack, solving real marketing challenges for our B2B customers. As more of the world's biggest car brands come on board, we're growing our engineering team and the volume of data we process for them. Right now we're building lead qualification across communication channels and bringing it together in our Single Customer View, while optimising our event-driven architecture for growing workloads.

You'll join a small, high-discipline squad, ship to production from your first weeks, and take on more scope and independence as you go, with real room to grow your craft and your career with us. We'll invest in your development, and you'll be working alongside engineers who care deeply about how they build and will help you raise your game.

What you'll own

You'll own the delivery of features within your squad, shipping well-tested, production-ready Elixir that moves our product and our customers' results forward, and growing your scope and independence as you go.

Your first 90 days

By day 30: you've found your feet in our codebase and domain, paired with the team, and shipped your first small changes to production.

By day 60: you're picking up features independently, writing well-tested code and taking an active part in technical and product discussions.

By day 90: you're a productive, trusted member of your squad, shipping regularly and starting to shape how we approach problems.

What you'll be doing

Build and ship product features in Elixir and Phoenix LiveView, from idea through to production, several times a week.

Write well-tested, maintainable code using test-driven development, and take part in pairing and code reviews to keep quality high.

Help shape the how and the why , bringing your own viewpoint to technical and product discussions and to our roadmap.

Work across our event-driven architecture , building services that talk over APIs and RabbitMQ and handling a growing volume of customer data reliably.

Use data and observability to understand how your changes behave in production and whether they're delivering value for customers.

Grow your craft , learning from a team that cares about how it works, with a clear path toward senior over time.

What you'll bring

A solid foundation in computer science fundamentals, whether from a CS degree or equivalent demonstrable grounding in data structures, algorithms, complexity and how systems work under the hood.

Some professional backend experience, ideally with Elixir or a similar language, and a genuine drive to deepen your Elixir skills.

Some experience with web development, ideally server-rendered UI (we use LiveView with TailwindCSS).

A habit of writing tested, maintainable code, and an interest in practices such as continuous delivery, TDD, pairing, code review and retrospectives.

A data-driven mindset: you care whether the work genuinely helps customers, not just whether it ships.

The judgement to use AI tools well: you use them to go faster, and your CS grounding means you can evaluate what they produce and steer away from suboptimal solutions rather than taking the output on faith.

A desire to keep learning and growing, and to collaborate closely in a small team.

Bonus points

Production experience with Elixir, Erlang/OTP, Phoenix or LiveView.

A background in Ruby or another functional language.

Experience with event-driven systems, RabbitMQ, PostgreSQL or Redis.

Exposure to Kubernetes or Google Cloud.
