Ideal candidate
Mission-driven RF engineer with hands-on hardware instincts who wants designs tested in real contested environments and enjoys collaborating across electronics, software and systems teams.
Requirements
- Have designed and integrated RF systems in a professional engineering context, ideally within aerospace, defence, or another demanding, safety-critical domain
- Understand RF fundamentals deeply enough to reason from first principles, propagation, antenna theory, link budgets, modulation schemes, noise, and interference
- Have hands-on experience with RF test and measurement equipment, and are comfortable debugging real hardware, not just simulation output
- Have worked on systems that need to survive a contested or degraded RF environment, or can reason confidently about what that requires
- Can interpret complex datasheets and specifications for RF components (amplifiers, filters, mixers, antennas)
