📋 Description

• Design, build, and maintain scalable async backend services and APIs in Python. • Own core systems end-to-end: architecture, implementation, testing, deployment, and operational excellence. • Build systems for multi-tenant workflows, fine-grained permissions, integrations, and agent-driven product experiences. • Write and review database migrations and row-level security policies in a compliance-sensitive environment. • Improve reliability, observability, and performance across critical paths. • Collaborate closely with product, design, and research to translate user needs into robust backend architecture. • Contribute to engineering standards, code review culture, and team ways of working. • Help shape technical direction in a fast-moving environment with evolving product requirements.

🎯 Requirements

• 5+ years of professional software engineering experience with substantial backend development experience. • Strong production experience building backend services in Python. • Strong experience with asynchronous programming in Python, such as asyncio, async database access, or high-concurrency service development. • Deep PostgreSQL experience, including schema design, query tuning, transactions, and production migrations. • Experience designing or implementing multi-tenant data isolation and access control. • Strong software design fundamentals: modular architecture, testing discipline, maintainability, and clear interface design. • Experience with Redis or similar infrastructure for caching, queues, rate limiting, or pub/sub. • Ability to independently own projects and make sound technical tradeoffs in ambiguous environments. • Strong communication skills and a collaborative, low-ego working style. • Strongly preferred: Experience with FastAPI, Starlette, Litestar, or another modern Python web framework. • Experience building backend systems for AI products, agentic workflows, or LLM-powered applications, such as RAG pipelines, tool-calling agents, or orchestration layers. • Experience with security-sensitive or enterprise systems, including access controls, audit logging, and compliance-driven engineering constraints. • Experience with OpenTelemetry or comparable production observability tooling. • Nice to have: Experience with pgvector, SurrealDB, or other vector retrieval systems. • Exposure to SOC 2, fintech, healthtech, or other regulated environments. • Experience with agent runtimes, sandboxing, or MCP integrations. • Familiarity with distributed systems, asynchronous processing, and performance optimization. • Startup or zero-to-one experience. • Comfort reading TypeScript or React during frontend-backend integration work.

🏖️ Benefits

• Work on technically challenging products at the intersection of AI, security, and enterprise software. • Join a small, senior team with deep experience in research, distributed systems, and production engineering. • Have meaningful influence over architecture, product direction, and engineering culture. • Build products with real-world impact, not just prototypes.
