Radiation Engineer — Spacecraft & Payloads - TeraWave

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 Tera Wave, 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.

Tera Wave 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 Tera Wave 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.

*** Develop, maintain, and execute the Tera Wave 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…
