About the role

This is not a traditional consulting or drawing-review role.
Define primary, secondary, and rack-level cooling boundaries.
Establish pumping, flow-control, pressure-management, balancing, and redundancy strategies.

Armada is seeking a Senior Mechanical Systems / Design Engineer to lead the design and development of liquid cooling and mechanical distribution systems for our modular AI data center platforms.
This role sits at the intersection of mechanical design, hydraulic engineering, thermal infrastructure, manufacturing, controls, and commissioning.
You will own the mechanical distribution architecture connecting heat-rejection equipment, pumps, piping, manifolds, coolant distribution units, rack cooling systems, and modular interconnects.
This is not a traditional consulting or drawing-review role. You will help establish the design rules, technical standards, interfaces, and commissioning philosophy behind the product itself.
Own the end-to-end mechanical cooling and fluid-distribution architecture for modular data center platforms.
Develop scalable architectures that support multiple product configurations and deployment sizes.
Develop hydraulic models for water and glycol-based systems.
Mechanical Design and Documentation
Own P&IDs, mechanical schematics, equipment schedules, valve schedules, instrumentation schedules, and design calculations.

Working at Armada means taking ownership, driving autonomy, and delivering impact.

Armada is the hyperscaler for the edge, delivering modular AI infrastructure from first deployment to AI factory with speed, scale and sovereignty.
Named one of Fast Company's Most Innovative Companies and to the CNBC Disruptor 50, Armada's solutions are deployed in over 60 countries globally for organizations ranging from energy to defense.
With nearly $500 million in funding to date, Armada is backed by leading investors including Founders Fund, Lux, BlackRock and Microsoft (M12), alongside strategic partnerships with Microsoft, Dell, Palantir, NVIDIA, SpaceX, and Skydio.
We are building the infrastructure layer for sovereign and edge AI - rugged, deployable compute for customers that cannot rely on centralized cloud.
You'll tackle challenges that haven't been solved before and help build something transformative from the ground up.
What you do here will not only define your career but help further Armada's mission to bridge the digital divide for customers around the world.
