Team Discover owns a core part of the customer journey at intersport.de search, navigation, category pages, filters and recommendations. Our work directly impacts how customers explore products and how the business grows.
We are a small, empowered product team with end to end ownership. That means we take responsibility for what we build and how it performs in production.
We are looking for a Senior Full Stack Engineer with strong frontend expertise who enjoys solving product relevant problems, working across the stack, and taking real ownership.

- Develop and maintain frontend applications with a strong focus on performance, scalability and usability
- Contribute to backend services, APIs, and event driven systems where needed
- Help shape technical decisions across architecture, tooling and build vs buy questions
- Work closely with Product, Design, and Engineering to define and deliver impactful solutions
- Take ownership from idea to production, including quality, performance and operational stability

- Strong frontend expertise with modern TypeScript based frameworks
- Solid full stack engineering skills and willingness to work across frontend and backend

- Good understanding of system design, APIs, databases and cloud based architectures
- Product mindset and the ability to balance technical quality with business impact
- Ability to ensure observability of systems in production, including metrics, logging, tracing, and alerting
- Experience with backend technologies such as Kotlin / Spring Boot, event-driven systems (e.g. Kafka), and cloud environments (AWS), or strong ability to ramp up quickly
- High level of ownership, self direction and comfort working in an autonomous team
- Strong communication skills in German and English
Nice to have
