Principal Mechanical Engineer (Structural Design and Analysis)

Epirus is a high-growth technology company dedicated to overcoming the asymmetric challenges inherent to the future of national security. Epirus' flagship product, Leonidas, is a software-defined system built using intelligent power management techniques which allow power-hungry systems to do more with less.  

Job Summary: This is an exciting role in a growing company. The ideal candidate for the position is someone who has experience designing and analyzing complex structures and electronics assemblies. In this role, you will work closely with a talented engineering team to design & analyze cutting edge electronic and mechanical assemblies to survive in harsh environments.

• Design and derive structural and vibration requirements for existing and future systems and contribute to early-phase product development by driving high-level design decisions.
• Design and analyze mechanical structures for mounting RF phased arrays and other electronic packages.
• Perform structural finite element analysis (FEA) on complex mechanical structures and electronic assemblies for a range of solution and load types, including static, modal, and structural dynamics (vibration and shock). Own and critically review entire analysis process.
• Build finite element models and perform hand calculations to verify structural integrity across Epirus’s product lines.
• Coach and mentor teammates and serve as mechanical design / analyst lead on product design teams
• Experience deriving structural requirements & load cases for large-scale mechanical systems and flowing down requirements into subsystems.
• Collaborate with a cross-functional team to develop requirements, design, and build electromechanical systems that survive harsh environments encountered during operation and transport 

• BS degree in Mechanical, Aerospace, Structural or similar engineering field and 8+ years of experience in structural design & stress analysis of metallic structures (or 6 years of experience with a Master’s degree).
• Expert level comfort with Finite Element Analysis and structural hand calculations.
• Experience with structural analysis and pre/post processing software packages such as Nastran, FEMAP, Ansys, NX-CAE, Patran or equivalent.
• Experience analyzing systems under static loading, shock, and vibrational environments including random vibration.
• Experience with CAD and practical application of GD&T.
• Experience with environmental test and qualification of mechanical systems. 

• Experience designing / analyzing actuated mechanical systems including azimuth and elevation pointing mechanisms.
• Experience performing stress analysis of electronic systems such as circuit card assemblies.
• Good written and oral communication skills.
• Collaborative; capable of working across all levels of the organization.
• Organized; comfortable working in a fast-paced, ever-changing environment.
