Mechanical Engineer - Hydronics

About this role

Armada seeks a Mechanical Engineer to design and own the hydronic distribution system for modular liquid-cooled data centers, managing piping, valves, instrumentation, and interconnects across primary and secondary cooling loops. This hands-on role bridges concept through manufacturing, installation, and field operation while collaborating with internal teams and external partners.

What you'll do

• Design and own hydronic distribution architecture for primary water and secondary PG25 cooling loops
• Develop piping, valves, instrumentation, module interconnects, and serviceability strategies
• Ensure systems are repeatable, commissionable, maintainable, and scalable across multiple deployments
• Collaborate with engineering teams, OEMs, fabricators, controls, manufacturing, and commissioning leads
• Manage transition from concept design through manufacturing, field installation, startup, and long-term operation
• Standardize mechanical distribution layer for robust real-world deployment

What they're looking for

• Hydronic distribution system design and expertise
• Piping and valve selection and sizing
• Instrumentation and process controls knowledge
• CAD and mechanical design software
• Manufacturing and fabrication process understanding
• Field commissioning and startup experience
• Cross-functional collaboration and stakeholder management
• Scalable system architecture design
