About the role

Responsibilities

  • Build core primitives end to end for entity ownership, audit, authorization, and orchestration.
  • Own the domain model, turning concepts of power, datacenters, and chips into composable entities.
  • Define interactions with external vendor systems, ingesting formats such as KMZ, BIM, and Revit.
  • Make AI agents first-class operators by providing tools, guardrails, and audit trails.

Requirements

  • Comfortable moving toward ambiguity, building maps, and explaining them.
  • Rapid learner who reaches competence in unfamiliar domains quickly (e.g., workflow engines, authz models, geospatial formats).
  • Strong taste in abstraction, identifying core primitives and knowing when not to over-abstract.
  • Rigorous domain modeling experience, learned from past mistakes and pain points.
  • Experience pulling structure from messy, unstructured data (from ML, data engineering, or research).
  • Fluent with AI tooling including LLM APIs, MCP servers, agentic frameworks; daily use of Claude Code, Cursor, or similar.
  • Shipped production code that others depend on; comfortable in any language with AI coding assistance.

Nice-to-Haves

  • MLE work, especially extraction and synthesis from unstructured data.
  • Experience with workflow and orchestration engines (Temporal, Cadence, Airflow).
  • Geospatial (KMZ/GIS) or BIM (Revit, IFC) knowledge.
  • Authorization and policy engines (OPA, Zanzibar-style, RBAC/ABAC).
  • Audit or event-sourcing systems.
  • Proficiency in Go, TypeScript, and Postgres.
