Reliability Engineer, R&D

Fluidstack•Austin, TX

1d•$203,000 - $232,000

About The Position

Fluidstack exists to make humanity more free by delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. This involves acquiring power, designing and building data centers, and operating them. The company is singularly focused on speed and scale as key differentiators in building civilization-scale infrastructure for AI. They hire people who care deeply about this problem space and operate with extreme ownership, full autonomy, velocity, first principles thinking, and a passion for the problem. This role will own reliability engineering for the reference design, including modeling availability, identifying weak points, and engineering fixes before deployment. The engineer will build RAM (Reliability, Availability, Maintainability) models, quantify failure rates, redundancy, and maintainability, and run cross-discipline FMEAs to catalog and design out failure modes with engineering teams. The role also involves closing the loop with the fleet by feeding field failures back into models and design changes.

Requirements

Done reliability engineering for infrastructure, energy, or complex hardware.
Built availability models decision-makers used.
Led cross-discipline FMEAs that changed designs.
Mine field data for the truth about failure rates.
Argue redundancy trade-offs in dollars and nines.

Nice To Haves

Data center topologies.
RAM modeling software.
Weibull analysis.
Maintenance strategy design.

Responsibilities

Own reliability engineering for the reference design: availability modeled, weak points found, and fixes engineered before deployment.
Build the RAM models: failure rates, redundancy, and maintainability quantified per configuration.
Run FMEAs across disciplines: failure modes cataloged and designed out with the engineering teams.
Close the loop with the fleet: field failures fed back into models and design changes.
