Senior Electronics Engineer – High-Reliability Space Hardware (m/f/d)

We are looking for an experienced electronics engineer to help mature our electronic systems toward reliable and qualification-ready space hardware. You will join projects with existing architectures and prototype designs. Your role will be to assess these designs critically, identify gaps in reliability, EMC, verification, component selection, and failure behaviour, and drive the necessary improvements. This is a senior hands-on engineering position without immediate personnel responsibility. As our electronics team grows, the role can develop toward broader technical responsibility.

What You Will Do

• Assess existing electronic architectures and designs with regard to requirements, robustness, failure behaviour, testability, and future qualification needs.
• Identify technical risks and recommend practical design improvements.
• Develop and review mixed-signal and power electronics, including sensor interfaces, power distribution, protection circuits, monitoring, and actuator or valve drivers.
• Translate system requirements into hardware requirements, interface definitions, design assumptions, and verification objectives.
• Perform circuit and subsystem analyses such as worst-case analysis, derating assessment, and electrical stress analysis.
• Perform electronics-related FMEA/FMECA activities and provide technical input to system-level failure and reliability analyses.
• Plan and execute structured hardware bring-up, debugging, robustness testing, and fault-injection testing.
• Prepare EMI/EMC pre-compliance and formal test activities, including test objectives, configurations, expected results, and acceptance criteria.
• Select components with consideration for electrical performance, availability, lifetime, derating, failure behaviour, and future qualification constraints.
• Define electrical PCB layout constraints and review layouts for grounding, return paths, EMC, power integrity, signal integrity, and testability.
• Document important requirements, design decisions, analyses, and verification results.
• Work closely with junior electronics engineers as well as software, control, mechanical, test, and system engineers.

• A degree in electrical engineering or a comparable technical background.
• Several years of hands-on experience developing and testing electronic hardware.
• Experience with complete electronic subsystems rather than only individual circuit blocks.
• Experience in a high-reliability, mission-critical, or safety-relevant environment such as aerospace, automotive, medical, railway, industrial safety, or space.
• Strong schematic design and circuit analysis skills in mixed-signal or power electronics.
• A solid understanding of component tolerances, temperature effects, electrical stress, protection concepts, and electronic failure behaviour.
• Practical laboratory experience with hardware bring-up, debugging, and structured testing.
• The ability to work from requirements through design and analysis to verification.
• Strong written and spoken English.

Strongly Preferred

• Practical experience with one or more of the following:
• EMI/EMC design and test preparation
• FMEA, DFMEA, or FMECA
• Worst-case circuit analysis
• Derating or electrical stress analysis
• Requirements-based verification
• Fault-injection or robustness testing
• Design reviews in a regulated or structured development environment

We do not expect candidates to be specialists in every discipline listed above. We are looking for someone who understands how reliable electronics are developed and can apply structured engineering judgement to unfamiliar problems.

Nice to Have

• Experience with space hardware, ECSS, EEE components, environmental testing, or qualification planning.
• Experience with sensor electronics, solenoids, valves, motors, DC/DC conversion, or power distribution.
• Experience with Altium Designer or a comparable ECAD environment.
• Experience with SPICE-based simulation.
• Familiarity with Python, MATLAB, or similar tools for analysis and test automation.
• Experience supporting or mentoring less experienced engineers.

• Meaningful technical responsibility for hardware used in real space systems.
• The opportunity to mature existing prototypes into robust, qualification-ready designs.
• Close collaboration across electronics, software, control, mechanics, test, and systems engineering.
• The opportunity to influence our electronics development, verification, and review processes as the team grows.
• Permanent full-time position with flexible working hours and 30 days of annual leave.
• Bike leasing, EGYM Wellpass, Deutschlandticket subsidy, professional development opportunities, company events, and complimentary beverages.
