About the company 

OrbitAID Aerospace is building the foundation for a new era of on-orbit servicing and refueling, enabling satellites to operate longer, maneuver more freely, and deliver greater value in space. At the core of this vision is the development of standardized docking and refueling technologies and a future network of orbital fuel stations, transforming how spacecraft are designed, launched, and sustained in orbit. 

Our long-term goal is to make space operations more flexible, resilient, and sustainable where satellites are serviced, upgraded, and refueled rather than replaced. We are a small, driven team that values strong engineering fundamentals, ownership, and hands-on problem solving. At OrbitAID, you’ll work closely across disciplines, move quickly from concept to hardware and software, and contribute directly to building the space infrastructure that will power the next generation of missions. 

 

Role Overview 

We are seeking an RF Hardware Design Engineer to join our team. In this role, you will be responsible for the design, development, integration, and validation of RF communication hardware for spacecraft and satellite missions. Your primary focus will be on developing spacecraft communication boards, RF transceivers, RF front-end electronics, and antenna systems for TT&C, payload communication, and high-speed data transmission across multiple frequency band applications. 

 

Key Responsibilities 

  • Design and develop spacecraft RF communication boards, RF front-end circuits, transceivers, and communication subsystems for satellite communication applications across Multiple frequency bands.
  • Design, simulate, develop, integrate, and optimize spacecraft antenna systems, antenna feed networks, and impedance matching circuits, ensuring compliance with mission performance requirements. 
  • Develop multilayer RF PCBs, including schematic capture, controlled impedance routing, stack-up definition, grounding, shielding, signal integrity, thermal management, and Design for Manufacturability. 
  • Configure, integrate, and optimize RF transceivers and communication hardware for TT&C, payload communication, and high-speed data transmission systems. 
  • Perform RF circuit, electromagnetic (EM), and antenna simulations using tools such as HFSS, CST Studio Suite, ADS, AWR, or equivalent to optimize RF and antenna performance. 
  • Select, evaluate, and characterize RF components including LNAs, Power Amplifiers, Mixers, Filters, Oscillators, PLLs, RF Switches, Duplexers, and passive RF components based on system performance and reliability requirements. 
  • Support PCB fabrication, assembly, hardware bring-up, debugging, RF characterization, antenna measurements, and performance optimization using VNA, Spectrum Analyzer, Signal Generator, Oscilloscope, RF Power Meter, and other laboratory equipment. 
  • Support environmental qualification, EMI/EMC compliance, thermal, vibration, and reliability testing to ensure flight readiness of RF hardware and antenna systems. 
  • Collaborate with RF Systems, FPGA, Embedded Software, Mechanical, AIT, and Manufacturing teams to ensure successful integration, verification, and deployment of spacecraft communication subsystems. 
  • Prepare engineering documentation, participate in technical and design reviews, troubleshoot complex RF hardware issues, and contribute to knowledge transfer and continuous improvement initiatives. 

 

Required Qualifications 

  • Bachelor's or Master's degree in RF & Microwave Engineering, or a related field. 
  • 2+ years of experience in RF hardware design, preferably in satellite communications, aerospace, defense, radar, or advanced wireless communication systems. 
  • Strong understanding of RF and microwave engineering fundamentals, transmission line theory, impedance matching, and RF front-end architecture. 
  • Hands-on experience with RF simulations, PCB development, hardware bring-up, and laboratory validation. 
  • Strong analytical, debugging, and problem-solving skills with the ability to work in multidisciplinary engineering teams.

 

Required Skills 

  • Experience in spacecraft communication hardware development.
  • Hands-on experience with RF transceivers such as AD9361, ADRV9002, or equivalent SDR RFICs. 
  • Experience in designing spacecraft antennas, antenna feed networks, and RF front-end architectures.
