About the role

Key responsibilities & impact

You'll design the orchestration backend that manages complex LLM interactions.
Develop high-performance integration pipelines connecting our AI to Flock's massive data platform.

Partner with ML engineers on agentic workflows and platform teams to design robust APIs that ground AI in truth, ensuring our system remains performant as we process billions of data points daily.

Requirements

What you’ll need

Love for writing clean, performant code and a track record of building production-grade backend systems.
Strong proficiency in Python and TypeScript (Node) for building scalable web services, open to Go as well.
Experience with agentic patterns, including function calling, tool use (MCP), and orchestrating multi-step LLM workflows.
Ability to write and optimize complex SQL queries and data access patterns to ensure LLMs are grounded in real-time data without sacrificing latency or system performance.
Deep understanding of OpenAI/Anthropic/Gemini APIs, prompt engineering, and managing complex conversation state/context.
Proven ability to build seamless API integrations with LLMs, managing the bridge between unstructured model outputs and structured internal services through robust error handling and schema validation.
Strong database confidence with PostgreSQL, OLAP Databases, and Redis. You know how to use the right tool for the job to ensure fast retrieval.
Experience with microservice-oriented architecture and designing for scale (we handle 1B+ images daily).
Proficient with AWS services, Kubernetes (EKS), Docker, and CI/CD build tooling.
You thrive in "zero-to-one" environments, taking ambiguous problems and turning them into technical roadmaps.
Experience with LLM evaluation (LangSmith/Langfuse), vector search/RAG, or infrastructure-as-code (Terraform).
