Angel Aerial Systems - RF & Electrical Systems Engineer

Our aircraft already delivers roughly 3–4x the flight endurance of conventional drones in its class. Now we want to bring that same level of engineering to RF and communications.

We are looking for an RF & Electrical Systems Engineer with exceptional electrical engineering ability, strong RF depth, and a genuine passion for hardware design.

You will own systems from architecture through schematic design, PCB layout, bring-up, integration, flight testing, and production.

Responsibilities
Own command-and-control, telemetry, video, and payload-data communication systems across our 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

Required Qualifications
Bachelor’s degree in Electrical Engineering or a closely related discipline
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

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
