About The Position

Epirus is a high-growth technology company focused on national security challenges. Its flagship product, Leonidas, is a software-defined system that uses intelligent power management to help power-hungry systems do more with less.

Epirus is seeking an experienced structural analysis engineer to help develop the next generation of high-power microwave (HPM) products. The role involves designing and analyzing electronic and mechanical assemblies intended to withstand harsh environments, and following designs and analyses through their complete lifecycle, from concept through testing and verification. The engineer will also mentor colleagues and serve as a mechanical design and analysis lead on product teams.

For California, the stated starting pay range is $138,000–$193,000 USD. Compensation is influenced by factors including skills, experience, and office location. The position is subject to ITAR eligibility requirements: candidates must be U.S. citizens, lawful permanent residents, protected individuals as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required U.S. Department of State authorizations.

Requirements

• Bachelor’s degree in Mechanical, Aerospace, Structural, or a similar engineering field.
• At least 8 years of experience in structural/stress design and analysis of metallic structures.
• Expert-level proficiency in finite element analysis and structural hand calculations.
• Experience with structural analysis and pre/post-processing software such as Nastran, FEMAP, Ansys, Patran, or equivalent.
• Experience analyzing systems under static loading, shock, and vibration, including random vibration.
• Experience with CAD and practical application of GD&T.
• Experience with structural testing and qualification of mechanical systems.
• Must meet the stated ITAR eligibility requirements.

Nice To Haves
