Job summary

Pets Deli is seeking a Senior Backend Engineer to own reliable systems and guide architectural decisions from design through release. You’ll work on a custom Elixir/Phoenix platform for orders, billing and subscriptions, while sustaining a Node.js serverless backend.

You’ll collaborate with stakeholders to shape solutions, improve performance, and uphold coding standards, CI/CD and monitoring across the stack in a remote-first, Germany‑based team.

Qualifications

• At least five years of relevant technical experience.
• Strong Elixir/Phoenix experience, or senior-level experience with a language or framework built on similar principles, particularly functional programming, concurrency and message-based systems.
• Experience building reliable systems that handle many concurrent requests.
• Strong debugging and problem-solving skills.
• Experience with REST APIs, automated testing and CI/CD.
• The ability to work independently, explain technical trade-offs and turn incomplete requirements into a clear delivery approach.
• For candidates with an Elixir/Phoenix background, knowledge of OTP, GenServers, Supervisors, LiveView, Ecto and BEAM is desired.
• 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.

Responsibilities

• 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.
