Nanosatellite RF Subsystems Architect

GomSpace A/S; Aalborg; On-site; DKK 673,000 - 972,000; Full time

Job summary

GomSpace A/S in Luxembourg seeks an experienced RF Subsystems Engineer to design, develop and validate RF communication subsystems for ambitious nanosatellite missions.

You will own end-to-end RF subsystem architecture from link budget to firmware development, HIL testing and over-the-air validation, collaborating with GomSpace’s RF Hardware team in Aalborg. This role requires strong hands-on RF design, testing and systems integration in space contexts.

Qualifications

• MSc or PhD in Electrical Engineering, RF/Microwave Engineering, Telecommunications, or a related field.
• 5+ years of experience in RF subsystem design, testing, or integration for satellite or aerospace applications.
• Hands-on experience with UHF, S-band, or X-band communication systems.
• Proficiency in RF simulation and design tools CST, ADS, HFSS.
• Familiarity with modulation schemes (GMSK, QPSK, 8PSK, DVB-S2) and communication protocols (CSP, CCSDS).
• Experience with ECSS standards or space-grade RF qualification is a strong plus.
• Experience with RF payload design, DSP, or sensing systems would be considered an advantage.

Responsibilities

• Define RF subsystem architectures and perform trade-offs across frequency bands, performance, and constraints.
• Perform link budget analysis, RF chain modelling, and system-level performance optimisation.
• Specify RF subsystem requirements and interfaces in coordination with system and payload teams.
• Support integration, verification, and validation of RF subsystems, including HIL and over-the-air testing.
• Contribute to selection and oversight of RF front-end components and suppliers (UHF/VHF/S/X-band).
• Identify and assess onboard signal processing and data reduction algorithms for RF payloads.
• Assess radar emitter detection, classification, and geolocation techniques using pulse and spectral analysis.
