Reliability Engineer, Data Center Design

Fluidstack•Austin, TX

4d•$200,000 - $250,000

About The Position

Fluidstack is building civilization-scale infrastructure for AI, aiming to deliver 10 to 100s of GWs of compute faster than anyone else. This role is within the Data Center Design Team, which is responsible for leading the design, development, and execution of over 50GW of data centers this decade, driving next-generation cooling and electrical distribution systems, and developing/scaling modular data centers. The team also influences behind-the-meter designs for multi-GW campuses. The company culture emphasizes extreme ownership, velocity, first principles thinking, and a passion for the problem space, often involving long hours at high intensity.

Requirements

Personally built reliability block diagrams and fault tree analyses for mission-critical electrical and mechanical systems.
Run Monte Carlo simulations for system availability using PTC Windchill Prediction, ReliaSoft, or equivalent tools.
Proficient understanding of IEEE 493 (Gold Book) and IEEE 3006.5 to defend failure-rate and repair-time assumptions.
Managed reliability models, component data, and version control inside PTC Windchill as the system of record.
Understand data center MEP systems well enough to model them accurately: MV/LV electrical distribution, standby generation, UPS, chilled water plants, CDUs, and building management/controls systems.
Quantify risk instead of describing it; prefer providing a P90 availability number over qualitative descriptions.
Translate technical reliability findings into figures usable for lease documents, SLAs, or investor decks.

Nice To Haves

PE license.
Direct experience benchmarking designs against Uptime Institute Tier III/IV classifications.
Liquid or hybrid cooling reliability modeling.
Managing outside reliability consultants or engineering firms on a deliverable basis.

Responsibilities

Build and maintain reliability block diagrams and fault tree analyses across the full MEP service chain, from utility intake to rack-level IT load, running Monte Carlo simulations of at least 100,000 iterations to produce P50/P90/P95/P99 availability distributions.
Own the reliability study at each 30% and 90% design gate for Fluidstack's own templates, and run independent reliability assessments of EPC-proposed, colocation, and acquired-site designs benchmarked against Uptime Institute Tier III/IV classifications.
Manage third-party reliability consultants and review their RBD, FTA, and Monte Carlo work for methodology soundness, turning identified single points of failure into prioritized design recommendations before capital is committed.
Maintain the reliability model, component data, and full audit trail inside Windchill PLM, and produce availability statements, sensitivity analyses, and FMEA summaries for lease documents, SLAs, and investor materials.
Feed live-site failure and repair data from Operations and Commissioning back into the models, track modeled availability against measured uptime across the portfolio, and translate the components driving unavailability into maintenance, sparing, and capital allocation recommendations such as N+1 versus 2N.
