Senior Mechanical Design Engineer – Liquid Cooling Systems

• 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. 

• A go-getter with a growth mindset. You're intellectually curious, have strong business acumen, and actively seek opportunities to build relevant skills and knowledge 
• A detail-oriented problem-solver. You can independently gather information, solve problems efficiently, and deliver results with a "get-it-done" attitude 
• Thrive in a fast-paced environment. You're energized by an entrepreneurial spirit, capable of working quickly, and excited to contribute to a growing company
• A collaborative team player. You focus on business success and are motivated by team accomplishment vs personal agenda 
• Highly organized and results-driven. Strong prioritization skills and a dedicated work ethic are essential for you
