## About the role

We're hiring a software engineer to help create the data pipelines, machine learning infrastructure, and agentic systems that power our science. On the agentic side, that means writing the code that runs the loop an AI agent operates inside, not one-off prompts — designing how agents plan, call tools, orchestrate sub-agents, keep memory, check their own work, and decide when they're done, then shipping them into production to do real work across our genetics and drug-discovery pipeline.

## What they're looking for

- Build agent loops end-to-end — tool/function calling, planning, sub-agent orchestration, memory, and control flow that runs reliably and unsupervised
- Build the eval and observability harness — the tests, metrics, tracing, and guardrails that make agentic systems trustworthy in production
- Turn scientific and operational workflows into agents that take real action across our platform
- Ship full-stack features: React/Tailwind front ends and backend services that put these agents in front of scientists
- Design and launch production-grade systems, services, data pipelines, and machine learning infrastructure from scratch
- Use frontier AI-native development tools (e.g. Claude Code) to move fast
