Senior Electrical Engineer, Radiation Effects & Reliability About the Role:
As a Senior Electrical Engineer, Radiation Effects & Reliability, you will ensure our spacecraft electronics remain resilient against the harsh environment of space. You will own radiation assurance and reliability across electrical systems from architecture through on-orbit operations. In this hands-on role, you will lead radiation test campaigns, perform reliability analysis, and implement robust mitigation strategies. You'll be expected to move quickly, translate complex environmental data into actionable design decisions, and take ownership of system-level resilience that directly impacts mission success.
Responsibilities:- Own radiation effects and reliability across spacecraft electrical systems-from early architecture through on-orbit operations
- Define radiation and reliability requirements, translating mission environments into component- and system-level specifications
- Plan and execute radiation test campaigns (heavy ion, proton, gamma/TID) for components including FPGAs, ASICs, power electronics, and COTS parts
- Characterize and analyze Single Event Effects (SEE), Total Ionizing Dose (TID), and displacement damage; document results and drive design decisions
- Develop and implement avionics reliability strategies, including redundancy, fault detection/isolation/recovery (FDIR), derating, and robustness in degraded modes
- Design and implement mitigation techniques (e.g., ECC, watchdogs, latch-up protection, shielding) at both component and system levels
- Perform reliability analyses such as FMEA/FMECA, fault tree analysis (FTA), and worst-case circuit analysis (WCCA)
- Establish and maintain approved parts lists (APL) with a focus on radiation performance, reliability, and supply chain considerations
- Model radiation environments for LEO missions and conduct system-level risk assessments and margin analyses
- Partner cross-functionally with avionics, hardware, and software teams to ensure resilient, fault-tolerant system architectures
- Drive radiation assurance and reliability processes across the full lifecycle-from design and qualification through launch and on-orbit operations
Basic Qualifications:- Bachelor's degree in Electrical Engineering or a related field
- 4+ years of experience in radiation effects, avionics reliability, or high-reliability electronics
- Hands-on experience with radiation testing (SEE, TID) and familiarity with test methodologies and data analysis
- Experience with reliability engineering methods (e.g., FMEA/FMECA, FTA, derating, WCCA)
- Strong understanding of electronic components (FPGAs, ASICs, power systems, mixed-signal circuits) and failure mechanisms in harsh environments
- Ability to translate test and analysis results into actionable design and system-level improvements
Preferred Qualifications:- Advanced degree (MS or PhD) in Electrical Engineering, Nuclear Engineering, Physics, or related field
- Experience designing, qualifying, or supporting spaceflight hardware (LEO, MEO, GEO, or deep space)
- Deep expertise in Single Event Effects (SEU, SEL, SET) and practical mitigation techniques in digital and power systems
- Familiarity with radiation environment and analysis tools (e.g., SPENVIS, OMERE, NOVICE) and standards (e.g., NASA, MIL-STD)
- Experience with rad-hard or rad-tolerant design, component derating, and system-level trade studies under mass/power constraints
- Background working in fast-paced, high-reliability environments with tight iteration cycles (e.g., aerospace, defense, advanced hardware startups)
- Proven ability to take ownership of ambiguous problems and drive cross-functional engineering decisions
