What You'll Be Doing:

• Design, build, and productionize agentic systems that beat general-purpose AI agents in our domain.
• Develop MCP servers (tool design, description and schema) that improve the performance of other agents on tasks in our domain.
• Build evaluation frameworks with domain experts to measure answer quality, retrieval performance and scientific accuracy.
• Own production reliability & observability of agents you develop from instrumentation to model/provider evals.

Why This Role:

• Full ownership of a production agent stack that customers pay for
• Your evals help decide the roadmap: we build where we can measurably beat frontier general agents
• Small senior team, direct access to domain experts and real R&D users

Qualifications:

• Bachelor's degree in engineering, computer science or any field where analytical and critical thinking was demonstrated.
• 5+ years of software or ML engineering, including 1+ years building and maintaining production LLM-based systems.
• Designed evaluations for LLM or agent systems - eval sets, quality metrics, human-expert and/or LLM-judge pipelines.
• You have instrumented, monitored, and debugged live AI services (e.g., OpenTelemetry, Arize Phoenix, Langfuse, Datadog, or similar).
• Strong software engineering and system design fundamentals.

Nice-to-haves

• API/SDK product or MCP (Model Context Protocol) server design experience.
• Materials science, chemistry, or patent/IP domain exposure.
