We are looking for a Senior RF Engineer to take ownership of the radio communication subsystem across the full development cycle — from RF hardware and antenna design to embedded firmware, system integration, testing, and field validation.

The role requires strong hands-on experience with RF hardware, wireless communication systems, antennas, and embedded development.

Responsibilities

  • Design and improve RF circuits, RF front ends, and PCB layouts.
  • Develop and integrate antenna solutions for compact mobile platforms.
  • Work with receiver/transmitter chains, filters, amplifiers, impedance matching, and frequency synthesis.
  • Develop embedded firmware for STM32-based radio modules in C.
  • Integrate RF transceivers using SPI, UART, and I2C.
  • Design and optimize reliable communication links, including link-budget analysis.
  • Work with modulation, frequency hopping, spread-spectrum techniques, and mesh networking.
  • Integrate telemetry communication with flight controllers via MAVLink.
  • Identify and mitigate EMI/EMC issues and onboard interference.
  • Improve communication-link robustness in interference-heavy and contested RF environments.
  • Perform RF measurements using spectrum analyzers, VNAs, oscilloscopes, and related equipment.
  • Conduct laboratory and field testing and support product validation and certification.

Requirements

  • 5+ years of professional experience in RF / wireless communication systems.
  • Proven full-cycle experience: schematic → PCB → bring-up → testing → field validation.
  • Strong experience with RF hardware and antenna systems.
  • Strong knowledge of STM32 and embedded C.
  • Practical experience with RF measurement equipment.
  • Solid understanding of digital communication systems and radio-link design.
  • Experience with real-world hardware products or systems deployed in the field.
  • Ability to work independently and take technical ownership of the RF subsystem.
  • English sufficient for technical documentation.

Nice to Have

  • Experience with UAVs, avionics, or other mobile embedded platforms.
  • Experience with electronic warfare, anti-jamming, or congested RF environments.
  • Knowledge of LoRa / LPWAN, mesh networks, MAVLink, or SDR.
  • Experience with RF product certification.
