6d•$269,000 - $335,000

About The Position

Fluidstack is seeking a Software Engineer Tech Lead to set the technical direction for their internal platform, including architecture, shared primitives, and standards for other engineers. The role involves building complex components such as orchestration, integrations, and the underlying data model. The Tech Lead will also review designs and code to improve quality without hindering progress, and consolidate disparate tools into shared systems to increase efficiency. The company is focused on delivering large-scale compute infrastructure for AI, aiming to ensure AI development aligns with human freedom. They operate with a philosophy of extreme ownership, velocity, first principles, and a passion for the problem space, often involving long hours at high intensity.

Requirements

Have been the engineer others route hard problems to, and have shipped systems that outlived your tenure on them.
Have designed and built platforms or shared infrastructure other engineers depend on daily.
Hold a high bar in code review while keeping velocity, and know which corners can be cut and which can't.
Use AI coding tools as a force multiplier daily and get agents doing real work alongside you.
Have untangled a system that grew crooked and left it simpler than you found it.

Nice To Haves

Workflow and orchestration engines.
LLM APIs, MCP servers, and agentic frameworks.
Postgres at depth.
Internal tooling at a high-growth company.

Responsibilities

Set the technical direction for the internal platform: architecture, shared primitives, and the standards other engineers build on.
Build the hardest pieces yourself, from orchestration and integrations to the data model underneath the tools.
Review designs and code across the team, raising the bar without becoming the bottleneck.
Consolidate one-off tools into shared systems that make the next tool a day's work instead of a month's.
