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. Working at Armada means taking ownership, driving autonomy, and delivering impact. 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.
About the Role
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. You will translate system requirements into practical, serviceable, and repeatable designs that can be manufactured in a factory and deployed consistently across multiple sites. 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.
What You’ll Own
Mechanical and Liquid Cooling Architecture
- Own the end-to-end mechanical cooling and fluid-distribution architecture for modular data center platforms.
- Define primary, secondary, and rack-level cooling boundaries.
- Establish pumping, flow-control, pressure-management, balancing, and redundancy strategies.
- Align heat-rejection equipment, distribution piping, CDUs, rack manifolds, rear-door heat exchangers, and other cooling interfaces.
- Develop scalable architectures that support multiple product configurations and deployment sizes.
Hydraulic System Design
- Perform and review pipe-sizing, flow, pressure-drop, pump-head, and system-volume calculations.
- Develop hydraulic models for water and glycol-based systems.
- Account for fluid concentration, viscosity, temperature, fittings, valves, strainers, heat exchangers, and equipment pressure losses.
- Define control-valve, balancing-valve, bypass, minimum-flow, and differential-pressure strategies.
- Validate system performance across normal, part-load, maintenance, startup, and failure conditions.
Mechanical Design and Documentation
- Own P&IDs, mechanical schematics, equipment schedules, valve schedules, instrumentation schedules, and design calculations.
- Develop mechanical design criteria, basis-of-design requirements, and standard details.
- Define clear equipment and scope boundaries between plant systems, modules, CDUs, rack cooling, and field interconnections.
- Maintain disciplined revision control and technical traceability across the mechanical design package.
- Review vendor drawings, submittals, calculations, and equipment selections for compliance with system intent.
Modular Product Integration
- Define mechanical interfaces between factory-built modules and field-installed infrastructure.
- Develop repeatable interconnect strategies for supply and return piping, manifolds, flexible connections, isolation valves, quick disconnects, drains, vents, and leak detection.
- Establish labeling, connection, access, and installation standards that reduce field variability.
- Support product configurations designed for transport, rapid installation, and phased expansion.
Design for Manufacturing and Serviceability
- Develop layouts that support repeatable fabrication, assembly, inspection, testing, and installation.
- Standardize piping routes, fittings, valve assemblies, supports, connection points, and mechanical components where practical.
- Coordinate equipment clearances, removal paths, service access, drain points, vent points, and filter or strainer access.
- Partner with manufacturing teams to resolve buildability issues and improve future revisions.
- Translate field and factory feedback into product improvements.
Controls and Instrumentation Integration
- Define the mechanical measurement and control requirements for temperature, flow, differential pressure, pressure, leak detection, fluid level, pump status, and valve position.
- Partner with controls engineers to develop system operating sequences and alarm strategies.
- Support pump staging, variable-speed control, minimum-flow protection, equipment enablement, and failure-response logic.
- Help ensure mechanical system data is available for commissioning, operations, and remote monitoring.
Commissioning-First Design
- Design systems for safe and efficient filling, flushing, venting, draining, testing, balancing, and startup.
- Define isolation, bypass, temporary connection, and load-bank testing requirements.
- Develop or support factory acceptance, site acceptance, and integrated systems testing procedures.
- Establish performance-verification criteria for flow, pressure, temperature, heat rejection, controls, alarms, and failure modes.
- Work directly with commissioning and field teams during startup and troubleshooting.
Cross-Functional Engineering Leadership
- Partner with thermal, electrical, controls, structural, manufacturing, commissioning, supply chain, and product teams.
- Coordinate directly with OEMs, equipment manufacturers, fabricators, and engineering partners.
- Identify interface risks, design gaps, and single points of failure early.
- Make clear technical decisions while maintaining alignment across the broader product architecture.
- Communicate complex system behavior in a practical way to both technical and nontechnical stakeholders.

Washington's aerospace and defense sectors follow federal contracting requirements, which can affect which candidates employers are willing to sponsor.
What is the prevailing wage for sponsored mechanical engineer jobs in Washington?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
