Angel Aerial Systems - RF & Electrical Systems Engineer

Angel Aerial Systems; Cincinnati (OH); On-site; USD 90,000 - 140,000; Full time

Job summary

Angel Aerial Systems seeks an RF & Electrical Systems Engineer to own architecture through production for UAV platforms. You will design, bring up, test, and validate RF/mixed‑signal hardware and work with vendors to ensure robust EMI/EMC and flight readiness.

You will lead RF integration, antenna design, link budgets, embedded interfaces (UART, CAN, Ethernet), and perform flight tests while supporting FCC/FAA regulatory compliance.

Qualifications

• Bachelor's degree in Electrical Engineering.
• Strong experience designing, bringing up, and debugging electronic hardware.
• Proficiency with Altium Designer, including schematic capture and PCB layout.
• Strong analog, digital, power, and RF engineering fundamentals.
• Experience with antennas, RF propagation, impedance matching, link budgets, and wireless communication systems.
• Hands-on experience with oscilloscopes, logic analyzers, spectrum analyzers, VNAs, signal generators, and related laboratory equipment.
• Familiarity with embedded interfaces and networking, including UART, CAN, SPI, I2C, USB, Ethernet, TCP/IP, and UDP.
• Ability to independently troubleshoot complex electrical and RF problems at both the board and system level.

Responsibilities

• Own command‑and‑control, telemetry, video, and payload‑data communication systems across UAV platforms.
• Develop RF architectures, link budgets, antenna configurations, and wireless system designs.
• Select and integrate radios, antennas, filters, amplifiers, and supporting RF hardware.
• Design electronic hardware from concept through production, including schematic capture, component selection, PCB layout, board bring‑up, validation, and debugging.
• Develop mixed‑signal, digital, power, communications, and interface circuitry.
• Integrate processors, radios, sensors, cameras, power electronics, and other electronic subsystems.
• Design and troubleshoot UART, CAN, Ethernet, USB, SPI, I2C, and other embedded interfaces.
• Conduct antenna characterization, range testing, interference analysis, and system‑performance validation.
• Diagnose signal‑integrity, power‑integrity, grounding, EMI/EMC, and RF‑coexistence issues.
• Support FCC certification, EMI/EMC testing, and regulatory compliance.
• Develop test fixtures and engineering tools for development and production.
• Work directly with component, PCB, radio, antenna, and electronics vendors.
• Support hardware through flight testing, design iteration, production release, and manufacturing.

Preferred Qualifications

• M.S. or Ph.D. in Electrical Engineering, RF Engineering, or a related discipline
• Experience with UAVs, aerospace, robotics, or other size-, weight-, and power-constrained systems
• Experience designing RF PCBs, controlled-impedance layouts, antenna interfaces, filters, or RF front ends
• Experience with embedded processors, Linux, PX4, MAVLink, or UAV avionics
• Experience with battery-powered systems, DC/DC converters, or power electronics
• Experience with signal integrity, power integrity, grounding, shielding, and EMI/EMC
• Familiarity with FCC certification, FAA Remote ID, or other wireless regulatory requirements
• Experience taking electronic hardware through DFM, DFT, production release, and manufacturing
• FAA Part 107 Remote Pilot Certificate, or willingness to obtain one
