Job summary

INFUSE is seeking a Senior AI Engineer to design, build and run LLM-powered agents in production. You will own end-to-end development from scoping with stakeholders to deployment, evaluation and ongoing improvement.

You’ll work with Python and TypeScript, deploy in AWS, and integrate with multiple LLM providers. This is a fully remote role offering a collaborative environment and strong emphasis on product-minded engineering.

Qualifications

• 5+ years of software engineering experience, with production systems you've designed, shipped and supported.
• Proven experience building LLM-based agents or agentic workflows that reached production with real users.
• Hands-on experience with agent frameworks and SDKs: Claude Agent SDK, Claude Managed Agents, Pydantic AI, LangGraph or similar.
• Hands-on experience with MCP and RAG: you've built MCP servers or equivalent tool layers, and retrieval pipelines over real, messy data.
• Experience with multiple LLM providers and with AWS Bedrock: model selection, routing, fallbacks, cost and rate-limit management.
• Strong Python and SQL. Comfortable in TypeScript/Node.js.
• Solid production engineering on AWS: Docker, CI/CD, testing, observability.
• Product thinking and business focus: you start from the problem and its cost, define success in measurable terms, and own outcomes.
• Daily use of agentic coding tools (Claude Code, Codex, Cursor or similar), with the judgment to verify what they produce.
• Clear communication with technical and non-technical stakeholders, in English.

Responsibilities

• Design and build LLM agents and agentic workflows: tool use via MCP, structured outputs, retrieval (RAG), multi-step orchestration, human review steps where needed.
• Build and maintain MCP servers and tool layers that give agents governed access to company data and systems.
• Own quality and cost: evals and golden sets, per-agent telemetry (tokens, cost, latency, accuracy), prompt and model versioning, provider failover and model routing.
• Ship through CI/CD like any other production service: tests and evals in the pipeline, containerized deploys, monitoring, rollbacks.
• Contribute to shared platform pieces: the agent template, the LLM gateway, observability.
• Work directly with business stakeholders to scope, prioritize and validate use cases. Push back when something doesn't need an agent.
• Use AI coding tools daily. Claude Code is our default; deep experience with a comparable agentic tool also works. You drive the tool, verify its output and catch its mistakes.
