Space Radiation Engineer, AI Hardware

What to Expect

We are building the future of computing in partnering with SpaceX - a distributed, AI-optimized data center infrastructure operating in space. The terawatts orbital AI data center will be powered by Dojo - our custom supercomputer designed for the neural networks behind SpaceX, xAI, FSD, and Optimus.

As a Space Radiation Engineer, you will be the primary technical authority on ensuring high-performance AI accelerators (TPUs/GPUs), storage, and networking hardware can withstand the harsh space environment. You will lead the effort to transition from conventional hardware hardening to advanced architectural resilience, ensuring our data center scales safely while providing low-latency compute to terrestrial users.

What You'll Do

• Radiation Environment Modeling:Analyze and predict space radiation environments (trapped particles, solar events, galactic cosmic rays) for targeted orbital altitudes (LEO/MEO)
• AI Hardware Hardening:Develop shielding and mitigation strategies for cutting-edge AI accelerators to ensure Total Ionizing Dose (TID), Displacement Damage Dose (DDD), and Single Event Effect (SEE) tolerance
• Radiation Testing Campaigns:Plan and execute radiation testing campaigns (heavy-ion and proton beam) at national laboratories to characterize component sensitivity
• Architectural Resilience:Collaborate with computer architects to design software-defined fault tolerance, error detection, and correction techniques (ECC) to handle Single Event Upsets (SEUs)
• Simulation & Analysis:Use computational tools (e.g., GEANT4, MCNPX, NOVICE, SpaceRad, CREME) to model radiation transport through spacecraft shielding
• Root-Cause Analysis:Investigate radiation-induced anomalies and failures during simulation and testing, providing actionable design modifications
• Documentation & Standards:Establish radiation hardness assurance (RHA) plans and requirements for high-density, multi-layer printed circuit boards (PCBs)

What You'll Bring

• Degree in Physics, Electrical Engineering, Aerospace Engineering, or related technical field, or equivalent experience
• 5+ years of experience in space radiation effects analysis, modeling, and testing
• Proven experience with space radiation tools such as CREME96, SPENVIS, FASTRAD, or NOVICE
• Deep understanding of semiconductor physics and radiation impacts on microelectronics (ASICs, FPGAs, CPUs)
• Strong written and verbal skills to present risk assessments to project stakeholders
