Senior Mechanical Engineer, Thermal Analysis 

Epirus designs and builds cutting-edge, high-powered microwave (HPM) systems that have the ability to transform industries. With a successful foothold in the defense industry, where we invented directed energy weapon systems that surpass current capabilities, we’re creating new possibilities for intelligently-driven power products in commercial markets.  

Job objective: The ideal candidate for the position is someone who has experience designing, building, and testing thermal cooling solutions for phased array products and packaging RF assemblies. We are particularly interested in mechanical engineers that have experience in designing and testing systems to pass environmental qualification testing to commercial or military standards. The ideal candidate will have designed and successfully taken a system through various levels of environmental test. 

 Duties: 

• Define program and subsystem environmental requirements 
• Design thermal management / packaging solutions for RF power amplifier assemblies 
• Simulate electromechanical assemblies and full system thermal models 
• Define and execute component thermal tests and validation.  
• Support ruggedization of components to survive harsh environments 

 Required Qualifications: 

• Bachelor’s Degree in Mechanical Engineering or Aerospace Engineering 
• Comfortable using hand calculations and developing internal tools to analyze thermal performance of complex systems 
• Experienced in Thermal FEA  (Thermal Desktop, Solidworks Simulation or related), CFD (Solidworks FlowSim or related), and FEA pre/post-processors (FEMAP or similar) 
• Experienced in CAD design (Solidworks or related) 
• 5-8 years of relevant experience 
• Minimum experience includes at least 2 full product life cycles 
• US Citizen (future security clearance may be required) 

 Desired Qualifications: 

• Previous experience with RF systems or component mechanical design  
• Aerospace/Defense experience and/or military experience  
• Collaborative; capable of working across all levels of the organization 
• Organized; comfortable working in a fast-paced, ever-changing environment 
• Able to drive designs from basic concept through manufacturing and test 
• Experience in test and instrumentation of components and validating thermal models 
• Experienced in various manufacturing techniques (traditional and additive) 

Epirus was the magical bow with infinite arrows wielded by the Greek hero Theseus. Like our namesake, we strive to be fast, efficient, and limitless in our approach. This agility, combined with a culture of innovation in systems development, allows us to move quickly without losing the decades of lessons learned.     

We have developed technologies that leverage new breakthroughs in sensors and high-power microwaves, combined with computer vision and advanced software control. Our first broad-market application is a comprehensive defense system to defeat offensive drones at scale.
