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. 

Qualifications 

• Bachelor's degree in Electrical Engineering, Physics, or a related field (Master’s or PhD preferred). 
• 7+ years of industry experience in RF and microwave system design, test, and integration. 
• Deep understanding of RF system architecture, component behavior, and signal integrity across frequency bands from MHz to tens of GHz. 
• Proficiency in industry-standard tools such as Keysight ADS, HFSS, MATLAB, and Altium Designer (or equivalents). 
• Experience with high-power and low-noise amplifier chains, frequency conversion, and transmitter/receiver (Tx/Rx) systems. 
• Skilled in RF cascade analysis, impedance matching, intermodulation distortion, and thermal effects. 
• Proven track record of leading complex engineering projects from concept to production. 
• Strong interpersonal and communication skills with the ability to present to internal and external stakeholders, including customers and leadership teams. 
• U.S. Person as defined by U.S. export control regulations (required). 

Preferred Experience 

• Experience in defense or aerospace RF systems. 
• Familiarity with modular hardware architectures or software-defined RF systems. 
• Exposure to design-for-manufacturability and automated testing environments.
