Job summary

Fluidstack is seeking an experienced BMS Engineer to own end-to-end control sequences for data-center scale infrastructure in Austin. You will program, configure, and validate BMS logic, integrating chillers, CDUs, and monitoring systems.

This role demands hands-on sequencing, testing, and clear documentation to enable future engineers to own the work. The ideal candidate has hands-on BMS experience in large facilities, plus a track record of integrating BACnet/Modbus and vendor protocols, with

Qualifications

• Hands-on BMS platform programming for large facilities.
• Ability to write and optimize control sequences from scratch.
• Experience configuring and integrating equipment via BACnet/Modbus and vendor protocols.
• Ability to commission work and diagnose test failures.
• Documented logic with versioning for handoff to future engineers.
• Bonus certifications in Tridium/ALC/Siemens and knowledge of chilled water sequences.

Responsibilities

• Engineer BMS controls in reference design: sequences, points, graphics.
• Program and configure the platform with tested, versioned logic.
• Integrate chillers, CDUs, power monitoring, and third-party equipment.
• Support commissioning with functional tests and fixes fed back to standard.

Job description

About Fluidstack

We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.

How We Operate

• Be a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.

• Insane urgency. We drive everything forward as fast as possible.

• Reason from first principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.

• Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.

• Build something that actually matters. If you're going to spend your time, spend it on something that matters to the world.

Role Scope

• Engineer BMS controls in the reference design: sequences, points lists, and graphics for mechanical and electrical plant.

• Program and configure the platform: logic built, tested, and versioned like the software it is.

• Integrate the systems: chillers, CDUs, power monitoring, and third-party equipment speaking one language.

• Support commissioning: functional tests executed, failures diagnosed, and fixes fed back into the standard.

What We're Looking For

• You've programmed BMS platforms hands-on for data centers or large facilities.

• You write sequences from scratch and improve the ones you inherit.

• You've integrated equipment over BACnet, Modbus, and vendor protocols.

• You commission your own work and fix what testing finds.

• You version and document logic so the next engineer can own it.

• Bonus: Tridium, ALC, or Siemens certification. Chilled water and liquid cooling sequences. EPMS integration. Graphics standards.

We are committed to pay equity and transparency.
