Our requirements
- Strong English communication (C1+)
- Experience building scalable, robust backend systems within (or close to) the stack above
- Hands-on experience with AI tooling in your daily work (Claude Code, Cursor, etc.) — this is a hard requirement
- Comfort in a fast-paced, international startup environment
Optional
- Experience building LLM-powered features or workflows (OpenAI/Anthropic APIs, LangChain, agentic systems)
Your responsibilities
- Architect and ship the APIs and services that everything else depends on
- Own the AI plumbing end to end: retrieval, orchestration, tool-calling, streaming, and the evals that tell you whether the results are worth anything
- Make async and distributed workloads rock-solid — document ingestion, embeddings, and long jobs running on Redis
- Wire up integrations with what clients already use (email, document stores) and harden them for real-world traffic
- Put data security and isolation front and center, because clients are handing over material they can't afford to leak
About the project
You'll work on an AI-native platform for the legal industry — building agentic AI workflows that let legal teams delegate complex, multi-step work. Not just chat-based assistance, but actual end-to-end execution on documents: review, drafting, analysis, anonymization, translation, and semantic search.
The product is highly scalable and performant, handling large volumes of large legal documents. You'll work very closely with the product, with real ownership and impact on its direction. We're looking for top-tier engineers who deliver high-quality code and challenge decisions rather than just execute tickets.
