About the role
Role Scope
Build core primitives end to end: entity ownership, audit, authorization, orchestration. Make the right thing the default and the wrong thing hard.
Own the domain model: turn Fluidstack's world of power, datacenters, and chips into composable entities that still hold up years from now.
Define interactions with the outside: interface with vendor systems and ingest the formats our domain actually speaks (KMZ, BIM, Revit, vendor docs).
Make AI agents first-class operators of our systems: give them the tools, guardrails, and audit trails to act safely, not just advise.
What We're Looking For
Move toward ambiguity, not away from it. Walk into the fog, build the map, and explain it to everyone else.
Learn at a steep slope. Reach real competence in an unfamiliar domain fast (workflow engine, authz model, geospatial format). Value this over existing expertise.
Have taste in abstraction. See the one primitive hiding under five janky one-offs, and know when not to abstract.
Model domains with rigor earned the hard way. Gotten it wrong, felt the pain, and never forgot it.
Pull structure out of mess. Done real work turning messy, unstructured data into something usable, in ML, data engineering, or research.
Fluent with AI tooling: LLM APIs, MCP servers, and agentic frameworks; drive Claude Code, Cursor, or similar every day.
Shipped production code that other people depend on; comfortable in any language using AI coding tools.
Bonus
MLE work, especially extraction and synthesis from unstructured data.
Workflow and orchestration engines (Temporal, Cadence, Airflow).
Geospatial (KMZ/GIS) or BIM (Revit, IFC).
Authorization and policy engines (OPA, Zanzibar-style, RBAC/ABAC).
Audit or event-sourcing systems.
Go, TypeScript, and Postgres.
Salary & Benefits
Competitive total compensation package (salary + equity).
Retirement or pension plan, in line with local norms.
Health, dental, and vision insurance.
Generous PTO policy, in line with local norms.
Base salary range: $150,000 - $250,000 per year, depending on experience, skills, qualifications, and location. Total compensation may also include equity in the form of stock options.
Build and operate large-scale web indexing systems including corpus selection, searchable structures, quality/freshness models, and low-latency query serving. Requires deep expertise in information retrieval and distributed systems.
