Stellenbeschreibung

What You'll Do

We are looking for a (Senior) Backend Developer who takes ownership and thinks about backend systems from initial concept through to production. Whether you’re building robust APIs, designing high-performance database architectures, or integrating AI solutions, your hands-on mindset and technical judgment make the difference.

You will work closely with frontend, product, and AI teams and play an active role in shaping our technical future.

As a (Senior) Backend Developer (m / f / d), you will be responsible for :

  • Designing and implementing scalable server-side architectures and database models
  • Developing, maintaining, and evolving high-performance, secure, and maintainable backend services
  • Owning API design, versioning, and lifecycle management
  • Collaborating closely with frontend teams to integrate user-centric features
  • Building and operating scalable infrastructure for AI workloads and external API integrations
  • Ensuring high software quality through automated testing (unit, integration, and end-to-end)
  • Actively monitoring and evaluating new technologies and architectural trends

What you bring

Hard Skills

  • Several years of experience as a (Senior) Backend Developer
  • Strong proficiency in Kotlin, Java, or another JVM-based language
  • Solid understanding of modern backend development principles and architectures
  • Hands-on experience with LLM integrations (e.g. OpenAI, Anthropic, or comparable APIs)
  • Experience working with vector databases (Pinecone, Weaviate, Qdrant) for RAG implementations
  • Understanding of prompt engineering, context management, and AI orchestration frameworks (e.g. LangChain, LangGraph)
  • Experience with message brokers and queueing systems (e.g. RabbitMQ or similar) is a plus
  • Experience with Micronaut, MySQL, AWS, and Kubernetes is an advantage, but not a requirement
  • Business-fluent English and good German language skills

    • Soft Skills

  • Openness, courage, and a creative, solution-oriented mindset
  • Clear communication and strong alignment with both team and product stakeholders
  • High sense of ownership and strong quality awareness
  • Enjoyment of working collaboratively in a fast-paced, dynamic environment

    • What we promise

    Work Environment & Flexibility

  • Office-first company : Hybrid setup with 3 days in the office and 2 days working from home, offering flexibility in how you structure your work
  • Modern, air-conditioned office with plenty of natural daylight
  • Central location between Gleisdreieck and Potsdamer Platz with excellent public transport access
  • Spacious rooftop terrace with stunning views over Berlin

    • Benefits

  • Full coverage of a Germany-wide public transport ticket
  • Dog-friendly office – we’re happy to welcome four-legged team members
  • Corporate benefits platform with attractive offers and discounts across many brands
  • Company pension scheme with a 20% employer contribution – we invest in your future
  • Regular company and team events to strengthen collaboration and team spirit
  • After-work fun : Nintendo Switch, PS5, darts, and table football
  • Free drinks, fresh fruit, and muesli available at all times

    • Company Culture & Collaboration

  • Agile and modern mindset with open communication – every voice is heard
  • Meaningful areas of responsibility with a strong focus on practical, real-world legal solutions
  • The opportunity to actively shape our journey and contribute from day one
  • Feedback is part of our culture – we believe in continuous, shared growth

    • Fast Application Process

  • Fast feedback
  • 1. Approx. 20-minute introductory call with our HR team
  • 2. Approx. 60-minute on-site interview with your hiring manager
  • 3. Approx. 30-minute meeting with the management team
  • A prompt offer following the interview process

    • About us
