About the Role

Design, analyze, and validate wireless communication systems for satellite platforms. This role covers the full communication link: RF front-end and antenna design through modem architecture and ground station integration. You will work across S-band, X-band, K-band and UHF radio systems, performing link budget analysis and system-level performance evaluation to ensure robust, high-reliability communication links for space missions.

Responsibilities

  • Design and develop wireless communication systems for satellite platforms, including RF subsystems operating in S-band, X-band, K-band and UHF frequency ranges
  • Lead antenna design, simulation, and validation efforts to meet mission-specific coverage, gain, and pattern requirements
  • Support ground station design, integration, and operational readiness for satellite communication links
  • Perform link budget analysis and simulation to validate communication link performance across mission scenarios and operating conditions
  • Select, architect, and integrate COTS modem hardware, including part selection, validation testing, and system integration
  • Work closely with hardware and software teams to ensure seamless integration of the physical layer modem with other system components
  • Perform detailed performance analysis of the designed communication system, including link budget analysis, throughput, latency, and error rate characterization
  • Conduct RF and wireless system testing using lab-grade test equipment, including spectrum analyzers, signal generators, and network analyzers
  • Develop and execute test plans and validation procedures for RF, antenna, and modem subsystems
  • Troubleshoot and resolve communication link performance issues identified during integration, test, or field operations
  • Document design decisions, analysis results, and test data, and present findings in design reviews
  • Collaborate with systems engineering to define communication system requirements and trade studies
  • Support FCC certification and regulatory compliance efforts for RF transmitters, including equipment authorization filings, spurious emissions testing, and coordination with test labs
  • Ensure RF system designs comply with applicable FCC Part 25 (satellite) and other relevant domestic and international spectrum regulations
  • Prepare technical documentation and test reports required for regulatory submissions and spectrum licensing applications

Required Qualifications

  • Bachelor's or Master's degree in Electrical Engineering, RF/Wireless Communications, Aerospace Engineering, or related field
  • 7+ years of professional experience in wireless communication systems engineering, with a focus on satellite or space-based communication systems
  • Hands-on experience with S-band, X-band, and UHF radio systems for satellite communication applications
  • Demonstrated experience in antenna design, simulation, and validation testing
  • Experience with ground station design, integration, and operations
  • Strong background in link budget analysis and communication system simulation
  • Experience selecting, architecting, and integrating COTS modem hardware, including component-level validation
  • Proficiency with wireless/RF test equipment, including spectrum analyzers, signal generators, vector network analyzers, and BERTs
  • Solid understanding of physical layer modem architecture and its interfaces to hardware and software systems
  • Experience performing communication system performance analysis, including throughput, latency, and error rate characterization
  • Strong analytical and problem-solving skills with the ability to troubleshoot complex RF/communication system issues
  • Effective communicator able to collaborate cross-functionally with hardware, software, and systems engineering teams
  • Familiarity with FCC certification processes and regulatory compliance requirements for RF transmitting equipment

Preferred Qualifications

  • Master's degree or Ph.D. in RF/Wireless Communications, Electrical Engineering, or Aerospace Engineering
  • Experience with space-qualified or radiation-tolerant RF hardware design
  • Familiarity with modulation and coding schemes used in satellite communication (e.g., QPSK, OQPSK, LDPC, Reed-Solomon)
  • Experience with satellite communication standards and protocols (e.g., CCSDS)
  • Background in phased array or steerable antenna systems
  • Experience with RF simulation tools (Ansys HFSS, Keysight ADS, or equivalent) and link budget/system simulation tools (STK, MATLAB/Simulink)
  • Familiarity with software-defined radio (SDR) platforms
  • Experience supporting satellite mission operations or field deployment of ground station equipment
  • Direct experience leading FCC equipment authorization filings (e.g., Part 15, Part 25) or working with FCC-accredited test labs
  • Familiarity with international spectrum regulatory bodies (e.g., ITU, ETSI) for cross-border satellite communication licensing
  • Publications or patents related to satellite communication system design

Compensation and Benefits

Salary range: $182,000 - $243,000 annually. Actual base salary depends on job-related skills, experience, qualifications, and internal equity.

  • Equity in Cowboy Space Corp.
  • Medical, dental, and vision insurance
  • 401(k) retirement savings plan
  • Paid time off
  • 10 paid holidays per calendar year
  • Paid parental leave
  • Relocation assistance if applicable
  • Daily lunch in the office and fully stocked kitchen with beverages and snacks
