Job description

Overview

We are seeking an experienced RF Engineer (510years) to design and analyze RF subsystems for next-generation satellite platforms. In this role, youll be responsible for end-to-end RF chain design including receive paths, transmit chains, front-end modules, and antenna integration and system performance optimization.

This is a hands-on role where youll take designs from concept through analysis, simulation, prototyping, and test, working closely with mechanical, systems, and mission teams to deliver reliable flight hardware.

What Youll Do

  • Design and develop RF receive and transmit chains , including LNAs, filters, mixers, PAs, and frequency conversion stages.
  • Perform cascade analysis for noise figure, gain, linearity, and dynamic range across RF chains.
  • Contribute to link budgets and verify compliance with system requirements.
  • Support antenna design, selection, and integration , ensuring proper impedance matching and radiation performance.
  • Perform RF board schematic and layout in Altium Designer , including grounding, shielding, and impedance control best practices.
  • Select and qualify RF components suitable for space and high-reliability environments .
  • Perform lab testing and characterization using VNAs, spectrum analyzers, signal generators, and other RF equipment.
  • Support system-level integration and troubleshoot RF issues during bring-up and test and on-orbit analysis and debugging.
  • Document designs, analyses, and test results for internal teams and external stakeholders.

What Were Looking For

  • B.S. or M.S. in Electrical Engineering or related field.
  • 5 years minimum of experience in RF design, layout, and test .
  • Strong background in RF receive / transmit chain design and cascade analysis .
  • Hands-on experience with Altium Designer (or equivalent PCB CAD tool) for RF layout.
  • Deep understanding of RF performance trade-offs : noise figure, gain, IP3, linearity, sensitivity, and power efficiency.
  • Proficiency with RF design and simulation tools (Matlab RF and Antenna Toolbox and HFSS).
  • Hands-on experience with lab equipment such as VNAs, spectrum analyzers, and power meters.
  • Excellent problem-solving and cross-functional collaboration skills.
  • Bonus

  • Experience with spacecraft RF systems , ground station hardware, or aerospace communications.
  • Knowledge of antenna arrays, beamforming, or phased-array systems.
  • Familiarity with modulation schemes, digital signal processing, or SDR integration.
  • Understanding of radiation effects and environmental testing for high-reliability RF hardware.
  • Experience with Digital Signal Processing (DSP) and Software Defined Radio (SDR).
  • Proficiency in one or more programming languages, especially C / C++ and Python.
  • Why Join Us?

  • Ownership of RF designs that enable cutting-edge satellite communications.
  • Work on both receive and transmit systems , from concept to flight hardware.
  • Join a collaborative team where your RF expertise directly impacts mission success.
