Senior Electronic Design Engineer - Space
Senior Electronics Design Engineer (Space Propulsion)
📍 Location: Paris region (Palaiseau) 💰 Salary: €55k–€80k (annual) 🏡 Note: Relocation required to the Paris area or nearby
🚀Join a fast-growing French SpaceTech startup, playing a critical role in designing cutting-edge electronics for innovative space propulsion technology with a proven track record in orbit.
Proven via 10+ years of research and development (R&D), our technology boasts exceptional in-orbit performance and strong commercial potential. Now advancing towards industrialisation and mass production, we’re building a capable 30-strong team in a technically demanding yet collaborative, innovative environment.
About the Role
You will own the integration, assembly, and testing of our propulsion systems’ electronic modules to guarantee:
- Quality and traceability in a controlled workspace
- Technological innovation through continuous improvement
- Close collaboration with our Avionics, Propulsion, and Thermal-Mechanical teams
In a dynamic start-up setting, you’ll participate in high-impact projects—shaping hardware for space while balancing engineering rigor with ingenuity.
Key Responsibilities
1. Electronics Design
- Route power electronics and onboard computer PCBs adhering to:
- IPC Class III
- ECSS (compliance)
- EMC standards
- Thermal management standards (e.g., temperature cycling)
- Model and simulate (electrical, thermal, EMC) to optimise performance and regulatory compliance.
- Uphold rigorous space and industrial standards (radiation hardened if applicable).
2. Test and Characterisation
(TBA in cleanroom conditions)
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
- Lead board testing alongside propulsion teams.
- Execute environmental test campaigns (vibration, thermal shocks, cyclic ageing).
- Inspect and triage test results to enhance reliability.
- Debug errors and assist test teams in troubleshooting.
3. Industrialisation and Partner Coordination
-
PCB process selection for assembly:
- Trial potting/conformal coating techniques.
- Validate manufacturability, assembly/ladder tolerances.
-
Negotiate with component partners/supply chain to improve:
- Cost control
- Lead time reduction
- Traceability of space-grade electronic parts.
-
Strive for ongoing improvements in hardware production methods (assembly micro-optimisation).
-
Provide subject-matter expertise to key stakeholders including:
- Space agencies
- End-users/customers
- Instrument manufacturers
Education & Experience
- Minimum 10 years in embedded electronics or related domain.
- Relevant academic credentials like a Master’s or engineering degree (MSc, BE) in:
- Embedded Electronics
- Electronic System Design
- Applied Physics/Mechatronics (with electronics focus)
(Shortlisting candidates with SQE/Bluetooth/Charcoal급 experience prioritised.)
Telemetry for Bonafides: 10+ years cumulative professional experience in:
- Embedded electronics design (logic boards, FPGA/DC-DC, low/noise dev)
- High-voltage PCB routing (Sub-100Vμ or <±1000V μ-space applications)
- Schematic capture (i.e., Altium Designer or similar)
- Board fabrication, checkout & خصوصه.: confirmed preference for practitioners of radiation-relevant PCB properties (GHz switch-mode power conversion topologies.)
