Description
We are seeking a Senior RF Engineer with a strong technical foundation, leadership capability, and a drive for innovation to join our fast-paced and growing team in Austin, TX. In this role, you will lead the design, development, integration, and testing of complex RF and microwave assemblies and subsystems for mission-critical applications in radar, electronic warfare (EW), aerospace, and defense.
This position plays a key role in advancing our modular RF architecture and driving the next generation of high-performance solutions using our proprietary X-Microwave platform.
Key Responsibilities
- Lead end-to-end development of advanced RF and microwave systems, from concept to production.
- Architect and design complex RF subsystems, including amplifiers, mixers, converters, filters, and transceivers.
- Perform high-level system modeling, simulations, trade studies, and design optimizations to meet performance, cost, and environmental constraints.
- Drive prototype development, hands-on testing, troubleshooting, and performance verification using advanced RF test equipment.
- Collaborate cross-functionally with internal teams, customers, and technical leads to ensure successful execution of project deliverables.
- Contribute to strategic product planning and technology roadmaps based on customer needs and market trends.
- Provide technical leadership and mentorship to junior engineers and engineering technicians.
- Support proposals, cost estimates, and technical responses for new business opportunities.
- Serve as industry expert on RF and microwave application needs to advise customers on optimal solutions and present proposals to technical experts from customers.
Requirements
Qualifications
