Qualis LLC is looking for a full-time Lead RF (Radio Frequency) Engineer to work in the Space Domain (SDA) and Missile Warning (MW) mission areas. This position will be filled in Huntsville, AL. Our team is dedicated to advancing the SDA and MW missions through focused and innovative research and engineering. We are on the cutting edge of Deep Space surveillance radar technology and radar hardware solutions to enhance mission capabilities.

We focus on delivering rapid, high-value solutions to our customers by recruiting, growing, and mentoring top technical talent. We are motivated technical staff who are interested in working independently, collaboratively, and performing high-impact work from day one. Our engineers are willing and expected to dive deep into developing solutions to the most challenging technical problems.

Responsibilities

The Lead RF Engineer will work within a multi-discipline team of engineers providing engineering support that addresses our customers’ needs implementing current technology in SDA and MW radars.

The Lead RF Engineer is responsible for the analysis, design, implementation, optimization, and enhancement of RF systems. The position applies comprehensive RF Engineering knowledge to support system performance, frequency conversion, signal routing, synchronization, calibration, interference analysis, and optimization.

The Lead RF Engineer provides program support by bringing knowledge and skills to a hybrid development environment where waterfall and agile practices are combined to quickly bring feedback during the design, development, and testing of new products.

The Lead RF Engineer will be a self-starter who works well both in teams and independently. They will have strong communication skills and robust attention to detail, organizational skills, and self-accountability. Additional responsibilities include (but not limited to):

• Lead RF engineering execution, provide technical direction, and resolve design tradeoffs and technical issues across the hardware-in-the-loop system.
• Develop RF technical plans, sequence engineering activities, and coordinate dependencies and design reviews with systems, software, firmware, mechanical, and test engineers.
• Define RF subsystem requirements, architectures, and interfaces, translating system performance needs into component and signal-path specifications.
• Direct and perform link-budget, frequency, and interference analyses to assess gain, loss, noise, linearity, isolation, and dynamic range.
• Guide and contribute to transmit/receive, channel-simulation, and frequency-conversion designs, including amplifiers, filters, mixers, switches, and attenuators.
• Establish RF routing and interconnection designs, addressing cabling, connectors, splitters, combiners, impedance matching, coupling, losses, and channel isolation.
• Guide RF and interface-board schematic and PCB development, fabrication, and bring-up, evaluating materials, shielding, grounding, and thermal effects on RF performance.
• Establish hardware selection criteria, review technical specifications and bills of materials, and coordinate procurement and supplier technical issues.
• Define hardware, firmware, and software interfaces, and coordinate RF control, configuration, data capture, and timing synchronization across the system.
• Establish RF calibration methods and configuration practices, and ensure affected signal paths are characterized and recalibrated after hardware changes.
• Plan and lead RF integration and verification, coordinate troubleshooting and corrective actions, and assess test…
