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

Epirus designs and manufactures novel RF systems for a variety of platforms in a rapid development environment. The Systems Engineer – Development role is a multidisciplinary role, with significant breadth (interacting with all engineering disciplines) and depth (from customer needs to unit-level specifications). The Systems Engineer – Development role will focus on typical Systems Engineering responsibilities, such as requirements definition & management (at system, subsystem, and component levels), system architecture, system analysis, change management, interface definition, etc. Additionally, in this role the Systems Engineer – Development engineer is a key stakeholder in integration, verification, and validation (IV&V) planning and execution to ensure products meet requirements. As much as possible, a Model Based Systems Engineering (MBSE) approach is employed to make Systems Engineering processes more thorough and efficient. As a fast-moving technology company, Systems Engineering at Epirus focuses on supporting the other engineering teams and facilitating rapid development, rather than focusing on overly bureaucratic processes.


  • Requirements
    • Own system requirements for a product, to include requirement definition and maintenance
    • Ensure Key Performance Parameters, as derived through mission modeling and operational analysis, are properly flowed to system requirements
    • Act as key interface with either existing or prospective customers to prove customer requirements / needs are fully satisfied by system requirements
    • Coordinate key requirements with subsystem design teams; ensuring requirement flow-down to hardware and software subsystems is captured and properly traced

  • Architecture
    • Collaborate with design engineering to establish the system architecture, capturing in MBSE diagrams (to include Structural and Behavioral Diagrams)
    • Maintain architectural definition throughout the development process to ensure team alignment
    • Develop interface control documentation and own interface management between hardware/software/firmware subsystems

  • Analysis
    • Perform trade studies and quick-turn impact analyses to facilitate agile hardware/software/firmware development
    • Perform analysis to prove system requirements are addressed by the system design
  • Ensure best practices for configuration management are adhered to
  • Facilitate multi-discipline coordination across teams
  • Participate in IV&V planning and preparation
  • Contribute technical writing and figures to proposals and other business development efforts
Basic Qualifications

  • Experience working with Systems Engineering tools for Requirements Management and Product Lifecycle Management (e.g. JAMA, Polarion, DOORS)
  • Experience working with MBSE (e.g. SparxEA, Capella)
  • Experience with Python development or other similar object-oriented languages
  • Experience working with Git/GitHub, or similar version control systems
  • Ability to identify gaps, prioritize in the context of the project / program, and lead an effort involving multiple engineers from other teams to resolve issues
  • US Citizen or Permanent Resident (future security clearance may be required)

Preferred Skills And Experience

  • Experience working with RF systems (e.g. radar, comms, EW, etc.), preferably including phased arrays
  • 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
  • Ability to anticipate and communicate blockers, delays, and cost ballooning within the project before they require escalation
  • Eager to train team members and help them overcome obstacles, resolve blockers, and complete work tasks
  • Organized; comfortable working in a fast-paced, ever-changing environment
  • Focused, with perspective on what matters most, rapidly delivering customer value
