Deine Rolle im Team
- The platform you'll work on We've developed a custom e-commerce platform built with Elixir and Phoenix. It is the system of record for orders, checkout, billing and subscriptions. You'll help extend its capabilities, maintain it and progressively migrate functionality from our legacy backend into it.
- Alongside this platform, we operate a Node.js serverless backend. Moving functionality into our core platform means understanding existing behaviour, managing dependencies and delivering changes in workable increments.
- Our technical environment includes: Core backend: Elixir and Phoenix. Database and hosting: PostgreSQL on AWS RDS, with our core platform deployed on ECS Fargate. Legacy backend: Node.js on AWS Lambda, DynamoDB, SQS and EventBridge. Frontend: Next.js, React and TypeScript, with Tailwind CSS, hosted on ECS Fargate. Integrations: Contentful and payment integrations including Mollie, Klarna, PayPal and Apple Pay. Monitoring: New Relic, Sentry and CloudWatch.
- What you'll do Build and maintain backend services, APIs and core functionality in Elixir and Phoenix, including migrating business logic from legacy services. Shape solutions with stakeholders: clarify requirements, evaluate trade-offs and break complex work into independently deliverable pieces. Make and document architectural decisions, improve existing code and resolve performance and reliability problems. Own quality from implementation through release: test critical paths, edge cases and interactions between services before handing work to QA, and use monitoring to validate releases. Lead code reviews, mentor other developers and help establish coding, testing and documentation standards. Improve development tools, CI/CD and engineering practices. Keep delivery visible by coordinating dependencies, raising risks early and communicating changes to scope or estimates. This is a fully hands-on senior engineering role, with responsibility for both the code you deliver and the technical decisions behind it.

For candidates with an Elixir/Phoenix background, we look for good knowledge of OTP, GenServers, Supervisors, LiveView, Ecto and BEAM. Experience with PostgreSQL, Docker, Kubernetes and monitoring tools is a plus. Full-stack development experience is a plus, particularly with React, Next.js and TypeScript.
