Senior Software Engineer, Integration and Test

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.  

Epirus designs and manufactures novel RF systems in a rapid development environment.  Fast and thorough hardware / software testing, from early R&D to production, is critical for rapidly delivering successful products. The Integration and Test Senior Software Engineer role focuses on developing and maintaining a level of excellence in Epirus’s engineering lab, where we perform R&D of new design improvements, acceptance testing of newly manufactured modules, integration testing at the sub-system and system levels, and ultimately chamber and field tests / demos.  Responsibilities include Hardware-in-the-Loop testing, developing software to control lab equipment, working with other engineers to design new test fixtures, automating testing for various units / sub-systems, organizing data logging, performing first look data analysis, and designing scaling systems that support larger hardware/software teams. Candidates should be capable software engineers but should also have an interest in working hands-on with hardware, both production hardware and lab equipment / instrumentation. Success in this role powers the data-driven decisions that enable Epirus’s agile hardware development.
