Mechanical Engineer, Robotics

Fluidstack; Austin (TX); On-site; USD 120,000 - 180,000; Full time

Job summary

Fluidstack is building civilization-scale infrastructure for AI in Austin, Texas. We seek engineers to design the mechanical systems that power data center robotics, from end effectors to docking interfaces, with a focus on reliability and manufacturability.

You will prototype quickly, test to failure, and iterate with controls and software teams to ensure robust, scalable hardware that runs unattended.

Qualifications

• Designed mechanical systems for robotics, automation, or mechatronics products.
• Took hardware from prototype through reliability testing.
• Designed interfaces and tolerances that survive real-world use.
• Practical testing by pushing to failure and instrumenting results.
• Worked in fast loops with controls and software.

Responsibilities

• Engineer the mechanical side of data center robotics: end effectors, docking, and interfaces between robots and plant.
• Design the physical integration for how robots handle, mate with, and service equipment.
• Prototype rapidly and test hard, moving concepts to instrumented trials in weeks.
• Productionize what works: design for manufacturability, reliability, and spares for unattended hardware.

Skills

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.

We hire people who care deeply about this problem space. If that is you, please apply!

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 the mechanical side of data center robotics: end effectors, docking, and interfaces between robots and plant.

• Design the physical integration: how robots handle, mate with, and service equipment designed for humans.

• Prototype fast and test hard: concepts to instrumented trials in weeks.

• Productionize what works: DFM, reliability, and spares for hardware that runs unattended.

What We're Looking For

• The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.

• You've designed mechanical systems for robotics, automation, or mechatronics products.

• You've taken hardware from prototype through reliability testing.

• You design interfaces and tolerances that survive the real world.

• You test to failure on purpose and instrument everything.

• You work in fast loops with controls and software.

• Bonus: End effector and gripper design. GD&T depth. DFM at low volume. Server and rack hardware familiarity.

We are committed to pay equity and transparency.
