Satellite TT&C Engineer

About the role

Aerospacelab, which designs and manufactures small satellites and develops earth observation services, is looking for a Satellite TT&C Engineer. The role owns the technical procurement of TT&C systems and equipment for LEO/GEO missions in S-band and Ka-band, and covers the full supplier management process from requirements to acceptance.

Key responsibilities

• Own the technical procurement of TT&C systems and equipment for LEO/GEO missions in S-band and Ka-band (and other bands as needed).
• Write and maintain TT&C requirements and specifications, and manage compliance through the procurement cycle.
• Define and control TT&C interfaces (electrical, RF, data) between spacecraft, TT&C equipment and ground segment via ICDs.
• Generate and review RF link budgets and RF performance metrics, including antenna pattern simulations, to validate supplier designs.
• Assess EMC/RFI requirements such as auto-compatibility and inter-satellite interference.
• Lead technical evaluation of supplier proposals, trade studies and compliance matrices against requirements.
• Ensure supplier deliverables meet ITU/national regulatory requirements and ECSS standards (e.g. ECSS-E-ST-50/70).
• Interface with ESA, national agencies and ground station providers (ESTRACK, KSAT, SSC, Leaf Space, AWS Ground Station) on ground segment compatibility, including LEOP phases.
• Manage suppliers through design reviews (PDR, CDR, TRR), progress monitoring, testing and acceptance.
• Maintain a market overview of TT&C products, suppliers and ground networks to inform make-vs-buy decisions.

Required profile

• MSc/PhD in Electrical, Telecommunication, Aerospace Engineering or a related field.
• 3+ years in technical procurement, systems engineering or supplier management for TT&C/telecom systems.
• Experience interfacing with ESA and/or national space agencies.
• Fluent English and strong communication skills.

Required skills

• Strong RF background: link budgets, RF performance metrics, antenna pattern analysis.
• Experience with EMC/EMI requirements and testing.
• Ability to write clear, verifiable requirements and specifications.
• Solid understanding of TT&C interfaces and ICDs.
• Good knowledge of ITU regulations (including Article 22) and frequency coordination/licensing.
• Working knowledge of ECSS standards.

Nice to have: TT&C subsystem design background, satellite constellation experience, spread spectrum techniques, ITU/FCC filing experience, SDR/DSP knowledge, RF analysis tools (HFSS, ADS, SystemVue), Python scripting for RF automation, prior space industry experience and willingness to work outside your comfort zone.

What we offer

• Permanent contract, open to all offices and remote work.
• Flat hierarchy and fast-paced environment.
• Flexible ways of working and a salary package consistent with experience.
