Job summary

Qualis, LLC is hiring a full-time RF Engineer to work in the Space Domain (SDA) and Missile Warning (MW) missions in Huntsville, AL. You will contribute to advanced radar hardware solutions and participate in cross-disciplinary teams delivering high-impact RF systems from concept through production.

The role requires leadership in RF analysis, design, and calibration, with a focus on performance, reliability, and compliance with military standards.

Qualifications

• Must be a U.S. Citizen with the ability to obtain an Active DoD Secret Clearance.
• Experience with government customers including the USAF and USSF.
• Understanding of Military and Industrial standards governing hardware design, selection, qualification, characteristics, etc.
• Familiar with the product lifecycle and have some experience applying technical standards, principles, theories, concepts, processes, and techniques to solve problems.
• Experience with design, integration, and transitioning products from development to production, and obsolescence management.
• Bachelor’s Degree and a minimum of 12 years of prior relevant experience, or a Graduate Degree and a minimum of 10 years of prior related experience.

Responsibilities

• Analyze RF subsystem requirements and develop design solutions for transmit, receive, and channel-simulation functions in a hardware-in-the-loop environment.
• Perform link-budget, frequency, and interference analyses to characterize gain, loss, noise, linearity, isolation, and dynamic range, and recommend design improvements.
• Design, integrate, and characterize RF modules and frequency-conversion circuits using amplifiers, filters, mixers, switches, attenuators, and related components.
• Develop and assemble RF signal paths using cables, connectors, splitters, and combiners, and evaluate impedance matching, coupling, losses, and channel isolation.
• Develop and review RF and interface-board schematics and PCB layouts, and support fabrication, assembly, board bring-up, and design corrections.
• Evaluate substrate and enclosure materials, shielding, grounding, and thermal effects on RF performance, and recommend practical design changes.
• Evaluate components and test hardware, prepare technical specifications and bills of materials, and support procurement and resolution of supplier technical issues.
• Implement and test RF hardware interfaces with software and firmware engineers, including control, configuration, status monitoring, and data capture.
• Integrate timing references and synchronization interfaces, and verify coordinated transmit, receive, and channel-simulation operation.
• Develop and execute calibration procedures, measure signal-path amplitude and delay, and update calibration data when hardware configurations change.
• Perform board, module, and system tests; investigate complex RF and hardware/software integration problems; and verify corrective actions against requirements.
• Document analyses, designs, interfaces, calibration data, and test results, and contribute technical findings and recommendations to design reviews and engineering plans.
