RF Communications Engineer (REMOTE)

Columbus Technologies and Services is hiring an RF Communications Engineer to design and integrate communication systems for lunar, deep-space, satellite, and other missions. The role develops subsystem requirements and architectures, analyzes communication performance, and supports modeling, testing, troubleshooting, and cross-functional integration.

Responsibilities:

• Design communication systems to support satellite systems in lunar orbit, deep-space, satellite, and other mission applications
• Define communication subsystem requirements and allocate requirements across spacecraft, payload, and ground system interfaces
• Develop RF communication subsystem architectures, interfaces, and test activities including antennas, transceivers, SDRs, LNAs, SSPAs, filters, multiplexers, and related hardware
• Develop and analyze communication link budgets to ensure mission performance requirements are met
• Define and implement communication waveforms, modulation schemes, coding/FEC techniques, and synchronization methods
• Perform RF system modeling, simulation, integration, testing, and troubleshooting activities
• Conduct communication performance analyses including Eb/No, carrier-to-noise ratio, throughput, coverage, access, and link margin assessments
• Ensure communication subsystem designs comply with applicable constraints, standards, and requirements
• Collaborate with cross-functional teams, including systems, software, avionics, GNC, payload, and ground systems engineers, to ensure successful communication system integration

Requirements:

• Must be a US Citizen or Permanent Resident
• Bachelor's degree in Electrical Engineering, Aerospace Engineering, Physics, or a related field
• 5+ years of experience in communications or related fields
• Experience developing communication subsystem requirements and interface definitions
• Excellent problem-solving and troubleshooting skills
• Ability to work effectively in a fast-paced, collaborative environment
• Experience with lunar, deep-space, or satellite communication systems
• Experience with Software Defined Radios (SDRs), optical, and/or RF communications systems
• Experience with communication analysis tools such as MATLAB, Simulink, STK, FreeFlyer, GMAT, or equivalent
• Experience with test equipment including spectrum analyzers, vector network analyzers, signal generators, and oscilloscopes
• Familiarity with government standards, CCSDS protocols, and spectrum management activities
• Experience supporting communication subsystem integration, verification, environmental testing, and mission operations
