Mechanical Commissioning Engineer, Capacity Delivery

Fluidstack•Austin, TX

9h•$150,000 - $204,000

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 involves acquiring power, designing and building data centers, and operating them. The company values extreme ownership, velocity, first principles thinking, and a passion for the problem space. The Commissioning Team is responsible for standing up a commissioning program for over 50GW of capacity this decade, running commissioning and QA-QC for novel modular data centers, and automating advanced commissioning levels. This role will commission mechanical systems for gigawatt-scale data centers, including chilled water plants, CDUs, liquid loops, and airside systems. The engineer will write and execute test scripts to verify capacity, redundancy, and failure response, and conduct functional and integrated systems tests with controls and electrical teams. Findings from testing will be used to improve standard designs for faster future commissioning.

Requirements

Commissioned mechanical plant on mission critical facilities through integrated systems testing.
Written test procedures from sequences of operation, and found where the sequence was wrong.
Read P&IDs and controls drawings fluently.
Troubleshoot live systems with vendors watching and a deadline standing behind you.

Nice To Haves

Liquid cooling and direct-to-chip systems.
CxA credential.
Modular data centers.
Test and balance oversight.

Responsibilities

Commission mechanical systems for gigawatt-scale data centers: chilled water plants, CDUs, liquid loops, and airside systems from Level 2 through Level 5.
Write and execute test scripts that prove capacity, redundancy, and failure response, not just that equipment turns on.
Run functional and integrated systems tests with controls and electrical so the building performs as one system.
Feed test findings back into the standard design so the next site commissions faster.
