Senior Full Stack Developer

We are looking for a Senior Full Stack Developer to own delivery across both our internal products and client projects for German customers. You will work end-to-end — from shaping requirements to shipping and maintaining production software — while helping us push the boundary on how AI accelerates engineering quality and productivity.

This is a role for someone who is deeply professional in their core stack, but curious and confident enough to jump into new technologies as projects demand. You will operate with a high degree of autonomy, so proactivity and strong communication are just as important as technical skill. 

• Must-haves

- 5+ years of professional software development experience, with strong full stack delivery capability (front end, back end, and the glue in between).

- Deep, professional expertise in at least one modern stack, plus the adaptability and willingness to jump into new languages, frameworks, and tech stacks as projects require.

- A track record of shipping and maintaining production products, not just prototypes.

- Fluent, professional English — spoken and written — for direct client and team communication.

- Genuine proactivity: you communicate early, raise risks, ask questions, and don't wait to be told what to do.

- Comfort working fully remote with strong self-discipline and accountability, including disciplined ticket hygiene (Jira) and honest time tracking (Clockify).

- Experience working in Agile teams — Scrum and/or Kanban — and comfort participating in daily stand-ups.

- Practical experience using AI tools to accelerate development, and enthusiasm for going deeper on AI-assisted workflows (e.g. harness and loop engineering).

• Nice-to-haves

- German and/or Vietnamese language skills.

- Experience working with or within DACH-region (German-speaking) teams and their quality and process expectations.

- Familiarity with GDPR-compliant development practices.

- Experience mentoring peers or driving engineering standards.

- Exposure across web, mobile, backend, cloud, QA, and automation.
