RF Spatial Engineer - High-Power Microwave Systems (Onsite)

Tower Eleven; Garden Grove (CA); On-site; USD 155,000 - 165,000; Full time

Benefits offered by this job

Relocation assistance

Job summary

Tower Eleven is seeking an experienced RF Spatial Engineer to design, develop, and validate high-power RF hardware for aerospace, defense, and satellite communications applications. You’ll own RF hardware through the full development lifecycle, from architecture to production support, focusing on SSPAs, BUCs, and quasi-optical power combining.

The ideal candidate will be hands-on at the lab bench, capable of circuit design, simulations, and collaborating with manufacturing to transition

Qualifications

• Bachelor's degree in electrical engineering, electronics engineering, RF engineering, or another relevant field.
• At least three years of direct, hands-on experience designing, simulating, building, and testing RF or microwave circuits and subsystems.
• Experience with high-power RF hardware, including SSPAs, BUCs, power amplifiers, or comparable microwave subsystems.
• Experience using RF or electromagnetic simulation platforms such as ADS, AWR Microwave Office, HFSS, or CST.
• Hands-on proficiency with RF laboratory equipment, including VNAs, spectrum analyzers, signal generators, oscilloscopes, and power meters.
• Experience measuring RF performance characteristics such as gain, efficiency, output power, noise figure, linearity, stability, and thermal behavior.
• Strong mathematical, analytical, and spatial-reasoning abilities.
• Demonstrated ability to troubleshoot complex RF hardware and resolve model-to-hardware performance discrepancies.
• Strong written and verbal communication skills.
• Detail-oriented, self-motivated, and comfortable taking ownership in a fast-paced engineering environment.
• Ability to work onsite in Cypress, California.

Responsibilities

• Design advanced spatial and quasi-optical power-combining architectures.
• Architect, simulate, and develop RF and microwave circuits and subsystems, including SSPAs, BUCs, power amplifiers, frequency converters, synthesizers, filters, mixers, and transmit/receive modules.
• Perform electromagnetic and RF/microwave simulations using tools such as ADS, AWR Microwave Office, HFSS, and CST.
• Translate system-level performance requirements and simulation results into optimized, production-ready hardware.
• Select, source, and evaluate RF components, including transistors, mixers, switches, and passive components.
• Develop detailed test and hardware-validation plans.
• Configure and operate VNAs, spectrum analyzers, signal generators, oscilloscopes, and power meters.
• Characterize prototype hardware for gain, output power, efficiency, noise figure, linearity, stability, and thermal performance.
• Investigate performance discrepancies and conduct troubleshooting, failure analysis, and root-cause analysis.
• Partner with mechanical, thermal, manufacturing, test, and quality engineers to ensure designs are reliable and manufacturable.
• Support new product introduction activities, including design reviews, manufacturability assessments, prototype builds, and production ramp-up.
• Resolve RF design, testing, reliability, and manufacturing issues and recommend corrective actions.
• Prepare design reports, test results, failure reports, root-cause analyses, and manufacturing-support documentation.
• Contribute to RF technology roadmaps and continuous product and process improvement.
