Job summary

Urban Sky in Denver seeks a Senior RF Systems Engineer to own the RF domain across the company—from vehicle boards to ground stations. You will ensure coexistence of SATCOM, GNSS, SDRs, and other emitters in dense RF environments.

The role requires 7+ years in RF systems engineering, hands-on testing with spectrum analyzers and VNAs, and experience with SDRs, secure communications, and mesh networks. On-site work near Denver with travel for field campaigns is expected.

Qualifications

  • B.S. or M.S. in Electrical Engineering, Communications Engineering, or a related field.
  • 7+ years of hands-on RF systems engineering across hardware and system levels, preferably in aerospace or high-altitude platforms.
  • Deep understanding of RF propagation, link budgets, modulation and coding, and antenna design principles.
  • Board-level RF experience with spectrum analyzers, VNAs, and debugging desense/interference.
  • Hands-on test experience with spectrum analyzers, VNAs, signal generators, and antenna measurement.
  • Experience with software-defined radios and mesh or relay network architectures.
  • Working knowledge of secure communications (encryption, key management) as applied to RF links.
  • Strong scripting/analysis skills for link modeling and test automation.
  • Experience with HABS, smallsat comms, or airborne relay architectures.
  • Contested-environment or electronic warfare experience (jamming, GPS denial, LPI/LPD).
  • ISM, L-, or S-band systems and adaptive modulation/coding.
  • RF payload experience: direction finding, TDOA/geolocation, SIGINT, or SAR.
  • Antenna simulation tools and an active US security clearance.

Responsibilities

  • Review and optimize every emitting and receiving system across our avionics and devices, including board-level RF review with layout, filtering, shielding, desense, and co-site interference.
  • Review and optimize antenna selection, design, and placement across the fleet, including LOS CSS radios, SDRs, SATCOM terminals, and GNSS.
  • Own RF link budgets across all mission phases and geometries, and validate them with hardware-in-the-loop and field testing.
  • Architect Urban Sky’s ground station systems and multi-node relay/bent-pipe topologies (balloon-to-balloon, balloon-to-ground, payload-to-ground).
  • Develop solutions for MIMO architectures, mesh data backhaul, and efficient routing topology.
  • Harden RF systems for contested environments: jamming resilience, GPS protection, and graceful degradation.
  • Develop secure, encrypted networking standards for RF-borne data across vehicle, ground, and customer interfaces.
  • Lead RF integration and interference deconfliction for third-party payloads hosted on our platforms.
  • Evaluate RF-sensing partners and payloads.
  • Support spectrum planning, frequency coordination, and regulatory compliance (FCC, ITU).
