RF Design Project Engineer

Stellant Systems Inc. (Stellant) is seeking an experienced RF Engineer to develop and maintain high-performance RF integrated microwave assembly and power amplifier products for space applications. We bring cutting-edge technology to mission-critical aerospace and defense programs, supporting commercial and government systems for orbital or terrestrial use. Stellant has delivered over 7000 active RF units since 1996, spanning UHF to Q-band.

About the role

The primary role is technical ownership of design, development, and production troubleshooting for RF/microwave assemblies and power amplifiers built in both SMT and chip-and-wire construction. As a senior engineer, you will guide a multi-disciplinary team through proposals, development, and production to meet program commitments.

Responsibilities

• Detailed design and schematic capture of RF/electronic circuits and overall product.
• Develop functional specifications for RF power amplifiers and integrated microwave assemblies.
• Support proposals for existing and future products.
• Perform design tweaks through full new designs for active RF products.
• Ensure bare die and bond wire layout designs meet requirements.
• Execute qualification on new development hardware.
• Release engineering design packages to production configuration management.
• Set up and calibrate RF test benches for Gain, Power, NF, and VSWR measurements.
• Develop automated methods for sub-system testing.
• Design power amplifier matching networks using non-linear models.
• Support production builds on development and flight hardware.
• Conduct root-cause investigations on built hardware.

Requirements

• Bachelor’s degree in physics or an engineering discipline; master’s degree a plus.
• Minimum 4–9 years of relevant engineering experience (level III: 4 years, level VI: 6 years, level V: 9 years; advanced degree may substitute for professional experience).
• 6+ years of direct RF and microwave assemblies experience.
• Hands-on experience with RF test equipment: network analyzers, power meters, bench power supplies, signal/waveform generators, high-speed oscilloscopes, noise figure analyzers, spectrum analyzers.
• Proficiency with Microwave Studios CST, Ansys HFSS, Microwave Office, ADS, or equivalent.
• Familiarity with development milestones: PDR, CDR, MRR, TRR, and RF device qualification.
• Experience supporting space hardware strongly preferred.
• Proposal experience.
• Hands-on manufacturing engineering experience a plus.
• Experience with engineering drawings and writing technical instructions.
• Computer programming skills a plus.
• Strong verbal and written communication; experience presenting to internal/external customers a plus.
• Ability to collaborate across disciplines (program managers, engineers, operations staff).
• Root-cause analysis experience a bonus.
• Proficiency in Microsoft Office applications.
• Must be a U.S. citizen, lawful permanent resident, or ITAR-protected individual.

Pay

$110,000–$175,000/year, depending on experience.
