• Use AI coding assistants to navigate unfamiliar codebases, accelerate development, prototype solutions
• Explore user problems through prototypes, instrumentation, experimentation, and collaboration
• Contribute to reliable deployment and infrastructure practices, with opportunities to work with Kubernetes, Helm, messaging systems, and related technologies

Requirements

• Experience developing SaaS products, ideally within an Agile and cross-functional product environment
• A backend specialization combined with a willingness to contribute to frontend, mobile, infrastructure, or other areas when required
• Familiarity with AI-powered coding tools such as Cursor, Claude Code, GitHub Copilot, or similar tools
• Strong product mindset and ownership mentality
• Experience with instrumentation, experimentation, A/B testing, Grafana, or Mixpanel is a plus
• Knowledge of Kubernetes and Helm is a plus
• Experience with PostgreSQL and messaging systems such as RabbitMQ or Apache Kafka is a plus
• Candidates at different experience levels are welcome, including engineers early in their careers

Benefits

• Remote-first working model with flexibility to work from home, within the European Union
• Opportunities for occasional in-person collaboration in Berlin or Stuttgart
• E-Gym-Wellpass membership covered by the employer
• Job bike leasing
