About Epirus

Epirus is a high-growth technology company developing software-defined high-power microwave (HPM) systems with devastating counter-electronics effects on modern drone threats. The Epirus Leonidas HPM family of products, empowered by innovations in AI and microelectronics, is human-safe and cost-effective. Distinguishing itself from lasers, Leonidas excels against drone swarms while also bending the cost curve back in DoD's favor - taking drone defeat costs from millions of dollars per drone to pennies on the dollar.

Job Summary: This is an exciting role in a growing company. The ideal candidate for the position is someone who has experience with high-power microwave (HPM) systems and their design, development, and testing. In this role, you will work closely with a talented engineering team to develop and test advanced HPM techniques and waveforms.


  • Communicate project status and results to senior leaders and key stakeholders
  • Lead design of experiments to determine the effectiveness of HPM techniques
  • Run parametric studies to determine optimal waveform parameters
  • Perform HPM susceptibility testing on benchtops, in chambers, and at field demonstrations
  • Generate target models to predict HPM coupling paths and component-level effects
  • Trace susceptibilities to their circuit-level effects within the unit under test (UUT)
  • Create theory of operations to explain results from experiments and predict effectiveness against untested targets
  • Define and iterate on concept of operations (CONOPS)
  • Develop novel functions/techniques/algorithms and perform design trade studies to inform system architecture
  • Focus on continuous improvement of internal processes
  • Contribute technical writing and figures to proposals and other business development efforts
  • Analyze data and write accurate and concise summary reports
  • Collaborate with other teams and across departments to answer their needs

Basic Qualifications:

  • BS degree in Electrical Engineering, Physics, Math, or equivalent
  • 8+ years of experience with systems engineering, RF engineering, Integration and Test or similar
  • Experience conducting laboratory tests of HPM sources and documenting their effects
  • Proficient in MATLAB and/or Python or equivalent computing language
  • Proficient with special test equipment (STE) including Oscilloscopes, Signal generators, Spectrum Analyzers, Power supplies, and power sensors
  • Background in HPM susceptibility testing, which may include the design of experiments, waveform design, and/or technique development.

Preferred Skills and Experience:

  • MS or PhD preferred
  • Good written and oral communication skills; not afraid to speak up, either to ask for help or disagree on a technical point that warrants more discussion
  • Collaborative; capable of working across all levels of the organization
  • Eager to learn and to help others on the team
  • Organized; comfortable working in a fast-paced, ever-changing environment
  • Familiarity with RF systems (e.g. radar, comms, EW, etc.). Some level of electrical hardware/lab experience, and/or field test experience
  • Familiarity with unmanned aircraft systems (UAS), their primary components, theory of operation, and control systems
