Job description

Software Engineer – RF/DSP | Shape the Future of Electronic Warfare

Build Real Systems That Matter

Are you ready to move beyond simulations and build real-world RF sensing systems that protect our nation? We're looking for a Software Engineer who thrives at the intersection of embedded systems, RF environments, and mission-critical software. This isn't a desk job, it's a hands-on technical role where you'll architect solutions, write code that runs on actual hardware, and see your work deployed in the field.

Why This Role is Different

• Real Impact: Your code powers Electronic Warfare systems that advance national security
• Technical Ownership: Become a subject matter expert on core embedded systems, not just a cog in the machine
• Cross-Functional Innovation: Collaborate directly with DSP engineers, hardware designers, and M&S experts
• Lab-to-Field: Participate in testing, data collection, and validation, not just development
• Cutting-Edge Tech: Work with SDRs, modern systems languages (Rust/Go/Zig), and next-gen RF architectures

What You'll Actually Do

• Design and develop embedded software for EW and RF sensing systems
• Architect HW/FW/SW partitioning for calibration algorithms and processing structures
• Build and integrate software for software-defined radios (SDRs) and RF front-ends
• Translate Electronic Warfare concepts (EA, ES, EP) into deployable capabilities
• Implement system models in C and MATLAB for optimal performance
• Collaborate with FPGA and hardware teams to integrate real-time algorithms
• Prototype operational capabilities, not just PowerPoints
• Shape the product roadmap through direct interaction with Engineering Leadership
• Support proposals and white papers for new opportunities

What We're Looking For

Must-Haves:

• Bachelor's degree in CS, EE, Physics, or related field
• Must have the ability to obtain and maintain a U.S. government issued Security Clearance . U.S. citizenship is required, as only U.S. citizens are eligible for a Security Clearances.
• 6+ years designing signal processing for EW systems
• Strong proficiency in C/C++, MATLAB, Python
• Experience with modern systems languages: Rust, Go, or Zig
• Hands-on experience with SDRs and RF data pipelines
• Working knowledge of Electronic Warfare concepts and RF/analog components
• Familiarity with DSP concepts and Linux development environments
• Excellent communication skills and ability to thrive in cross-functional teams
• Based in Dayton, Ohio (up to 20% travel)

Bonus Points:

• Master's degree with 3+ years of experience
• Experience with GNU Radio or similar frameworks
• Background in SIGINT, ELINT, or radar systems
• Familiarity with Open Architectures (OMS, FACE standards)
• Exposure to FPGA/firmware interfaces (VHDL/Verilog)
• Interest in REDHAWK, LabView, or Simulink
