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.

Why Driftrock

Driftrock's mission is to become the world-leading automotive and e-mobility marketing software platform, and help accelerate the transition to clean transport. We work with some of the world's biggest brands, including BMW, BYD, Mercedes-Benz and Volvo, and partner with the world's leading platforms, including Meta, Google, mobile.de and Auto Trader. We've been building since 2013, and our work enables billions of euros in vehicle sales every year. We're a close, fully remote team of 35 people across engineering, design, customer success, performance and commercial, spread across the world. That means your work has a real, visible impact on our product, our culture and how we operate. We're at the cutting edge of marketing technology, with plenty of room to unlock value from data and to help speed up the shift to electric vehicles.

How we work is shaped by four values:

• We care: about our team, our customers, and the people who see the marketing messages that we power. Work isn't done until we can prove it's useful to both the consumer and the customer.
• Be that person: if something needs fixing, fix it. It's never someone else's problem.
• People-first: we put people at the core of everything, and never compromise security or privacy for results.
• Be better today than you were yesterday: we bake learning and continuous improvement into everything we do, for ourselves and our customers.

In practice, this looks like:

• Weekly Monday Showcases where we share what we're learning.
• Regular retros.
• A budget to attend the courses and conferences that grow you.
• Donut coffee pairings to stay connected.
• An annual company Summit that brings the whole global team together in person.

What's in it for you

We're remote-first and flexible about how and where you work, with co‑working space available if you want it. Alongside your salary:

• Share options in Driftrock, on founder-friendly, tax-efficient EMI terms, including the option to retain vested options after leaving (at board discretion).
• Comprehensive Vitality health cover: medical, dental, vision, hearing, mental-health support and therapy, cancer cover, a free Headspace subscription and Vitality rewards.
• 24 to 28 days' holiday (24 + 1 extra each year, capped at 28), plus bank holidays.
• Pension contributions, life assurance (3x salary) and income protection.
• Electric car salary-sacrifice scheme (Octopus): save up to ~40%, with insurance, servicing and a charging perk included.
• Enhanced maternity and paternity leave.
• A learning budget for books, courses and conferences, plus time for personal goals.
• Perks and discounts via CharlieHR, and a BMW Group employee discount programme.

International team members

We're remote-first and hire globally. While some UK-specific benefits are delivered differently abroad, we strive for genuine parity. Wherever you are, the standard package includes a comprehensive health plan, pension contributions, paid time off including local bank holidays, share options, enhanced maternity and paternity leave, a learning budget, and our flexible working culture. International team members are employed compliantly via an Employer of Record (Remote.com). Salary bands are location-based and may vary depending on the employee's primary place of work.

Our hiring process

• A short intro call.
• A conversation with the hiring manager.
• A practical task based on real challenges, never unpaid spec work.
• A final conversation with the team.
