Firma i stanowisko

We build AI tools for firms in legal and professional services: software people use for real work, not demos. We started a few months ago and already have paying clients who rely on what we ship. The team is small and moving fast.

Wymagania

At least seven years building backend systems that run in production.
Consideration of failure modes, not just normal operation.
Experience building or strong interest in building real LLM-powered systems, including RAG, tool-calling, and agents.
Proficient use of AI coding tools with responsibility for code quality.
Adaptability to startup environments with changing directions.
Experience with Python (6+ years), FastAPI (3+ years), PostgreSQL/SQL, and Redis (2+ years).

Nice to have:

Experience with RAG or vector search.
Familiarity with LangChain or LlamaIndex.
Experience with streaming over SSE, WebSocket, or SignalR.
Microsoft Graph and email integration work.

Obowiązki

Designing and building the APIs and services our products run on.
Working on the AI plumbing: retrieval, orchestration, tool-calling, response streaming, and evaluation of output quality.
Keeping asynchronous and distributed work reliable, including document ingestion, embeddings, and long-running jobs on Redis.
Building integrations with client systems like email and document stores, ensuring they perform under load.
Taking data security and isolation seriously due to handling confidential client material.
