Job Summary
In this role, you will develop scalable backend and frontend solutions in .NET and React, manage interface implementation and testing strategies, and optimize database schemas for production application.
Job Technologies
Your role in the team
- Reporting to the CTO, as a Full Stack Developer you will work across the full platform - a modular monolith built in .NET 10 on the backend and React on the frontend.
- You will own features from requirement to production, working in a small, high-trust team where your decisions have direct product impact.
- Build and extend modules within a clean modular monolith architecture - Domain, Application, Infrastructure, and API layers per module.
- Implement message-based integrations over RabbitMQ and HTTP, with proper retry, dead-letter, and observability patterns.
- Design and own PostgreSQL schemas, migrations (Liquibase), and query optimisation for compliance-grade data integrity.
- Write code test-first - unit tests, integration tests with in-memory and real DB where appropriate, and end-to-end API tests.
- Contribute to and enforce coding standards, PR reviews, and architectural decisions.
- Build complex, accessible UI components and multi-path forms for compliance workflows.
- Maintain consistency with our design system and work closely with our UX designer on new feature implementation.
- Integriere dich mit dem Backend über typisierte API-Verträge, wobei Ladezustände, Fehlergrenzen und optimistische Updates korrekt gehandhabt werden.
- Use Claude Code as an active development tool - you will work with CLAUDE.md, SKILLS.md, and RULES.md context files to give the AI accurate codebase context.
- Translate Jira requirements and Notion design documents into structured Claude Code prompts that produce high-quality, testable code.
- Maintain and improve the Claude Code context layer as the codebase evolves, treating it as first-class documentation.
- Evaluate AI-generated code with the same rigour as human-written code - you own the output.
- Build and maintain Docker images for all services, following security and size best practices.
- Deploy and manage workloads on Kubernetes clusters - writing and reviewing manifests, Helm charts, and managing config/secrets.
- Collaborate with DevOps on CI/CD pipelines, environment configuration, and production readiness.
- Participate in on-call rotation for production incidents (light, given our scale).

Our expectations of you
Qualifications
- Genuine TDD discipline - you write tests before or alongside code, not as an afterthought; you understand the difference between unit, integration, and end-to-end tests.
- PostgreSQL proficiency - schema design, migrations, query analysis, and indexing.
- Docker fluency - you build lean, layered images and understand multi-stage builds.
- Strong English communication skills - written and verbal.
- Vertrautheit mit der Strukturierung von AI-Kontextdateien (im Stil von CLAUDE.md), um die Codegenerierung effektiv zu steuern.
- Exposure to knowledge graphs, Neo4j, or graph-based data modelling.
Experience
- 4+ years of professional .NET development (C#), with strong understanding of clean architecture and SOLID principles.
- Solid React and TypeScript experience - you write components that are readable, testable, and maintainable.
- Hands-on experience with RabbitMQ or similar message brokers in production systems.
- Practical Kubernetes experience - you can read and write manifests, understand pod scheduling, and debug deployment issues.
- Experience working in or contributing to a modular monolith or DDD-influenced codebase.
- Experience using Claude Code, GitHub Copilot, or similar AI coding assistants as a genuine productivity tool in a professional codebase.
- Experience with GCP (Cloud Run, Cloud Storage, Pub/Sub, Vertex AI).
- Playwright or similar e2e test framework experience.
