Remote Creo Jobs in Oregon (NOW HIRING)

• 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. 

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. 
  

Product ownership 

• You will help define a repeatable mechanical platform rather than deliver a one-time project. 

Concept through deployment 

• You will see designs move from calculations and P&IDs into fabrication, factory testing, commissioning, and field operation. 

High-density infrastructure 

• You will solve mechanical and liquid-cooling challenges associated with AI, HPC, and other high-heat-density compute platforms. 

Direct technical impact 

• Your decisions will shape equipment selection, system reliability, factory assembly, field deployment, and long-term serviceability. 
  

• 7 or more years of experience designing mechanical cooling, hydraulic distribution, process cooling, or mission-critical infrastructure systems. 

• Experience with data centers, semiconductor facilities, industrial process cooling, central utility plants, or comparable high-reliability environments. 

• Strong knowledge of pipe sizing, pump selection, pressure-drop analysis, flow balancing, system volume, and hydraulic control. 

• Experience developing and owning P&IDs, mechanical calculations, equipment schedules, valve schedules, and instrumentation requirements. 

• Practical knowledge of chilled-water, condenser-water, glycol, or process-fluid systems. 

• Experience designing for commissioning, maintenance, isolation, flushing, venting, draining, and service access. 

• Ability to coordinate across engineering, manufacturing, controls, commissioning, and field teams. 

• Strong technical judgment and the ability to own work with limited oversight. 
  

• Experience with direct liquid cooling for AI or HPC systems. 

• Experience with CDUs, rack manifolds, cold plates, rear-door heat exchangers, liquid-to-liquid heat exchangers, or liquid-to-air systems. 

• Background in modular, prefabricated, skid-based, or containerized infrastructure. 

• Experience with AFT Fathom, Pipe-Flo, or comparable hydraulic modeling tools. 

• Familiarity with CFD, thermal modeling, or transient analysis. 

• Proficiency with AutoCAD, Revit, Plant 3D, SolidWorks, Inventor, or similar design tools. 

• Experience supporting FAT, SAT, IST, or field commissioning. 

• Professional Engineer license or equivalent technical depth.
