Job description

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! Blue Origin is pioneering the future of space-based communications with TeraWave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.TeraWave combines LEO and MEO spacecraft, high-throughput RF payloads, optical inter-satellite links, propulsion power electronics, and high-performance avionics. The resulting radiation assurance problem spans mission environments, shielding and layout, EEE part susceptibility, solar-array degradation, materials effects, and fleet-level availability. As the dedicated TeraWave Radiation Engineer, you will own the end-to-end radiation hardness assurance (RHA) process. You will define mission-specific environments and margins, flow requirements to systems and parts, evaluate designs and test data, guide mitigation, and create the objective evidence needed to accept radiation risk. **Special Mentions** [*Edit or remove as needed*]* Relocation provided* Travel: Up to 15% based on business needs. **Responsibilities include but are not limited to:*** Develop, maintain, and execute the TeraWave RHA Plan for LEO and MEO spacecraft, payloads, avionics, EPS, propulsion electronics, sensors, optical devices, and solar-array technologies.* Define and control external and internal radiation environments over the applicable mission lifetime, including trapped particles, solar particle events, galactic cosmic rays, total ionizing dose (TID), displacement damage dose (DDD/TNID), and single-event effects (SEE).* Translate mission orbit, duration, confidence level, shielding, duty cycle, and availability needs into system, subsystem, unit, circuit, and EEE-part radiation requirements.* Establish and maintain radiation design margin policy, including risk/criticality-based margin tiers and documented rationale for confidence, uncertainty, and lot-to-lot variability.* Perform or direct shielding, dose-depth, sectoring/ray-trace, and part-location analyses; work with configuration and mechanical teams to maintain an analyzable spacecraft geometry.* Evaluate EEE parts and optoelectronics for destructive and non-destructive SEE, TID, enhanced low-dose-rate sensitivity, DDD, and application-specific failure thresholds.* Calculate mission SEE rates and translate device events into circuit, box, subsystem, and system effects such as reset rate, data loss, outage, degraded throughput, latent damage, or destructive failure.* Partner with EEE Parts Engineering to screen BOMs, assess applicability of heritage and vendor data, disposition radiation risk, and define lot-specific testing or procurement controls.* Partner with electrical, RF, optical, and avionics hardware designers on radiation mitigation, including part substitution, shielding, current limiting, latch-up protection, filtering, redundancy, circuit-level protection, and operating constraints.* Support solar-array degradation predictions and end-of-life power assurance with the Solar and EPS teams, maintaining traceability among radiation confidence level, degradation factors, and the authoritative power budget.* Maintain the radiation risk register, part-by-part evidence status, waivers/deviations, open tests, and residual risk; support design reviews and flight-readiness decisions.* Monitor emerging radiation-effects data and provide rapid application-specific guidance for new technologies, commercial parts, FPGAs/processors, memories, power semiconductors, RFICs, and photonics.**Minimum Qualifications*** B.S. in electrical engineering, nuclear engineering, physics, aerospace engineering, materials science, or a related technical discipline.* 5+ years of experience in spacecraft radiation effects, RHA, radiation test, electronic-device physics, or a closely related field.* Demonstrated knowledge of TID and SEE mechanisms, radiation environment modeling, shielding, and electronic design mitigation.* Experience interpreting radiation test data and determining whether data are applicable to a specific part, lot, operating condition, circuit, and mission.* Ability to derive and communicate radiation requirements, margins, assumptions, uncertainty, and residual risk across multiple engineering disciplines.* Ability to plan and execute technical work with external radiation test facilities and part suppliers.* Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.**Preferred Qualifications*** M.S. or Ph.D. in radiation effects, electrical engineering, nuclear engineering, physics, or a related field.* Experience with both LEO and MEO missions and with trapped-electron/proton environments.* Experience testing or analyzing modern commercial and automotive-grade electronics, FPGAs, memories, power devices, RF electronics, and optoelectronics.* Familiarity with JEDEC, ASTM, ESCC, MIL-STD-883, NASA EEE-INST-002, and radiation test standards/guidance.* Experience connecting device-level radiation response to hardware reliability, availability, system performance, and fleet operations.* Experience with radiation effects on photovoltaic cells, coverglass selection, optical materials, polymers, adhesives, or coatings.### Base Pay Range for:CA applicants is $156,802.00 - $219,522.45CO applicants is $144,179.00 - $201,849.90WA applicants is $156,802.00 - $219,522.45**Other site ranges may differ** **Culture Statement**Don’t meet all desired requirements?
