Staff Software Engineer

Role Scope

You make the right thing the default and the wrong thing hard. You own the domain model, turning Fluidstack's world of power, datacenters, and chips into composable entities that still hold up years from now. You define interactions with the outside, interface with vendor systems and ingest the formats our domain actually speaks: KMZ, BIM, Revit, vendor docs. You give AI agents the tools, guardrails, and audit trails to act safely, not just advise.

What We're Looking For

• You move toward ambiguity, not away from it. You walk into the fog, build the map, and explain it to everyone else.
• You learn at a steep slope. You reach real competence in an unfamiliar domain fast, whether it's a workflow engine, an authz model, or a geospatial format.
• You have taste in abstraction. You see the one primitive hiding under five janky one-offs, and you know when not to abstract.
• You model domains with rigor earned the hard way. You've gotten it wrong, felt the pain, and never forgot it.
• You pull structure out of mess. You've done real work turning messy, unstructured data into something usable, in ML, data engineering, or research.
• You're fluent with AI tooling. LLM APIs, MCP servers, and agentic frameworks, and you drive Claude Code, Cursor, or similar every day.
• You've shipped production code that other people depend on, and you're 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.
• The base salary range for this position is $150,000 - $250,000 per year, depending on experience, skills, qualifications, and location.
