Engineer Seattle WA- July 2026

Engineer - Radiation - Seattle WA - July 2026
We are seeking a Senior Electrical Engineer to join our client in the Seattle Area to lead radiation test campaigns perform reliability analysis and implement robust mitigation strategies.

Responsibilities:

• Own radiation effects and reliability across spacecraft electrical systemsfrom 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

• 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 lifecyclefrom design and qualification through launch and on-orbit operations

Basic Qualifications:

• Bachelors 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

Required Experience:

Senior IC
