Senior RF Design Engineer

Location: Los Angeles, CAEmployment Type: Full-TimeIndustry: Advanced Defense Technology / RF SystemsClearance Requirements: U.S. Citizenship required due to federal contractingAbout the CompanyJoin a cutting-edge engineering team working on next-generation RF and microwave solutions that enable mission-critical defense applications. Our company designs high-performance, software-defined systems that push the boundaries of what’s possible with RF power and intelligent signal control.Role SummaryWe’re looking for an experienced RF Design Engineer to take ownership of the design, simulation, and testing of high-power RF amplifier modules. You'll work across the full development lifecycle—evaluating components, designing circuits, integrating off-the-shelf parts, and verifying system performance. If you’re passionate about RF design and want to contribute to real-world solutions in national defense and security, this is the role for you.What You’ll Do

• Design and simulate high-power RF amplifiers for CW and pulsed applications (sub-10GHz)
• Evaluate and integrate off-the-shelf components such as MMICs, discrete transistors, splitters, and combiners
• Guide PCB layout, schematic capture, and support board fabrication and bring-up
• Perform bench testing using equipment such as VNAs, spectrum analyzers, signal generators, and load pull setups
• Optimize circuit performance for gain, efficiency, thermal stability, and impedance matching
• Collaborate with mechanical, thermal, and systems engineering to ensure first-pass success
• Develop test plans and support system/subsystem validation
• Assist with manufacturing and process improvement initiatives
• Interface with vendors to evaluate new components and capabilities

QualificationsRequired:

• BS or MS in Electrical Engineering (RF/Microwave focus preferred)
• 5+ years of experience in broadband high-power amplifier design (UHF to C-band or similar)
• Proficiency with RF simulation tools (e.g., Keysight ADS, Cadence AWR)
• Experience with schematic capture, PCB design collaboration, and RF circuit analysis
• Familiarity with test and measurement equipment for RF components
• Solid understanding of impedance matching techniques and power amplifier architectures

Preferred:

• Experience with 3D EM modeling (e.g., HFSS, CST, Feko)
• Exposure to RF filter design
• Prior involvement in low-to-medium volume production environments (dozens to hundreds of units)
• Comfortable in a fast-paced, highly collaborative engineering environment

Why Join Us?

• Work on game-changing RF tech that makes a difference
• Small team, big impact: your contributions matter
• Flexible, dynamic engineering culture with strong mentorship
• Competitive compensation and benefits

Ready to bring your RF design expertise to a high-impact team? Apply now and help shape the future of advanced defense systems.
