Principal Full-Stack Engineer | AI Start-Up | Remote, with occasional onsite (Germany)

I am partnered with an AI startup, backed by a significant round of funding looking for a principal-level software engineer who wants to apply big-system thinking to a smaller, faster environment.

You’ll be building production software that sits directly on top of large-scale generative models. That means turning research outputs into stable interfaces, reliable workflows, and product surfaces that hold up under real usage.

• Design and own full stack systems
• Build frontend applications
• Own backend APIs, data models, auth boundaries, and async processing
• Design event-driven pipelines for large media ingestion, background processing, retries, and failure recovery
• Work directly with research to define clean contracts between model outputs and product interfaces
• Raise engineering standards through architecture, reviews, and example implementations

• Type Script end to end
• React with Tailwind and Radix-based component patterns
• Convex-style backend architecture with strongly typed queries, mutations, actions, and realtime state
• Async-first design with explicit failure handling and observability
• AWS used narrowly and intentionally for Lambda, S3, and event triggers

• You operate at senior, staff, or principal level in a high-bar engineering environment
• You are comfortable owning ambiguous problems without layers of review or process
• You think about systems, in variants, and failure modes as much as code
• You can move fast without compromising quality of work
• You want your decisions to matter

• Experience productising ML or LLM-backed systems
• Python for tooling or model-adjacent work
• Experience with serverless or backend-as-a-service architectures

• Ownership of complete systems
• Clear line of sight from code to real users and outcomes
• Close collaboration with research and product
• High trust environment with strong technical autonomy
• Competitive compensation with meaningful equity upside
• Regular in-person time with a small senior team, without giving up remote flexibility
• Access to whatever tools or benefits you need to help you excel

If you’re looking for a technically demanding role with real impact and very little overhead, apply now
