Direct Radiating Array Responsible Engineer, MEO

SES

Betzdorf, Luxembourg

We are looking for an experienced and forward-thinking engineer to lead the development and delivery of the Ka-band Direct Radiating Antenna (DRA) subsystem for our satellite payloads. This role is central to the design, integration, qualification, and performance assurance of space-grade electronic hardware. You will be responsible for the technical execution of the DRA subsystem throughout the full satellite lifecycle.

The DRA subsystem includes a range of technologies—from analog high-frequency front ends (SSPAs, LNAs, filters) and power conditioning electronics to digital beamforming ASICs and high-speed SERDES. You will work closely with payload and satellite teams, with a strong focus on thermal design and system integration.

As a Senior Engineer, Direct Radiating Array Responsible, MEO, you will be in charge of

Subsystem Ownership & Technical Leadership:

Act as the technical lead for the Ka-band DRA subsystem, including active antenna elements, RF distribution, and digital beamforming electronics;
Define and manage subsystem requirements, interfaces, and performance budgets (e.g., EIRP, G/T, gain, noise figure, linearity);
Lead technical reviews, risk assessments, and design decisions with internal and external stakeholders.

Electronic Hardware Integration:

Oversee integration and qualification of space-grade components, including:
- RF front-end electronics (SSPAs, LNAs);
- Radiating apertures (patches, horns);
- High-speed digital ASICs for beamforming;
- Control and telemetry interfaces.
Ensure compliance with space environment constraints (thermal, radiation, EMC, mechanical);
Coordinate with ASIC development teams and suppliers to ensure subsystem readiness.

Supplier & Project Management:

Manage subcontractors and suppliers for DRA hardware, ensuring technical alignment, schedule adherence, and quality assurance;
Review and approve design documentation, test procedures, and qualification results.

Integration, Test & Verification:

Support payload integration and test campaigns, including:
- RF and digital performance validation;
- Functional testing of beamforming ASICs and control units;
- Troubleshooting during AIT and in-orbit commissioning.

Cross-functional Collaboration:

Work closely with systems engineering, mechanical, thermal, and AIT teams to ensure subsystem compatibility and mission success;
Contribute to payload-level trade-offs and system optimisation.

Documentation & Reporting:

Prepare technical documentation, compliance matrices, and customer deliverables;
Present technical status and findings to internal leadership and external customers.

YOUR PROFILE

Master’s degree or Ph.D. in Electrical Engineering, Computer Engineering, or a related field;
10+ years of experience in electronic equipment design, ideally in the space sector and/or involving high-frequency electronics;
Fluency in English; additional languages are a plus.

COMPETENCIES

RF & Microwave Hardware: Experience with space-qualified RF components (SSPAs, LNAs, filters, couplers) and RF chain performance validation;
Electronic Space Hardware: Strong background in developing and qualifying electronic hardware for space, including thermal, mechanical, radiation, and EMC compliance;
Ka-Band Payloads: Proven experience with Ka-band systems and RF performance metrics (EIRP, G/T, noise figure, linearity, isolation);
Direct Radiating Antennas (DRA): Hands-on experience with active antenna systems, phased arrays, and electronically steerable beams;
Digital Beamforming Systems: Familiarity with digital beamforming architectures and high-speed ASIC integration;
Reliability & EEE Parts: Experience with reliability analysis (WCA, derating, failure propagation) and EEE parts selection for space;
Project & Supplier Management: Skilled in managing suppliers, reviewing technical documentation, and ensuring quality and schedule compliance;
Soft Skills:
- Strong leadership and ownership mindset;
- Excellent communication and stakeholder management;
- Analytical thinking and problem-solving in complex systems;
- Collaborative and team-oriented approach.
