Senior Radiation Effects Engineer

Senior Radiation Effects Engineer

Astranis builds advanced satellites for high orbits, expanding humanity’s reach into the solar system. Today, Astranis satellites provide dedicated, secure networks to highly-sophisticated customers across the globe—large enterprises, sovereign governments, and the US military. With five satellites on orbit and many more set to launch soon, the company is servicing a backlog of more than $1 billion of commercial contracts. Astranis is the preferred satellite communications partner for buyers with stringent requirements for uptime, data security, network visibility, and customization.

This senior position requires technical leadership, hands-on expertise in circuit design, and a proven track record of validating high-reliability electrical components for space environments. The role involves architecting and designing fault-tolerant, radiation-hardened electrical systems and avionics architectures capable of operating reliably in high-radiation environments. It also includes leading simulation and modeling to evaluate Geostationary (GEO) and Geosynchronous Transfer Orbit (GTO) radiation effects, establishing methodologies and driving radiation testing campaigns to upscreen and qualify commercial off-the-shelf (COTS) and automotive-grade electrical components, collaborating cross-functionally with mechanical and structural teams to run 3D ray-tracing simulations (e.g., FASTRAD), and optimizing shielding levels versus mass trade-offs for sensitive electrical assemblies. Additionally, the role involves providing technical mentorship to junior engineers and supporting core electrical engineering activities, including schematic capture, PCB layout reviews, and hardware bring-up. Support the engineering team in recruiting efforts, technical interviewing, and mentoring additional teammates.

Requirements

• Bachelor of Science degree in Electrical Engineering (EE) or equivalent technical field (with an emphasis on electronics and semiconductor physics)
• Extensive professional experience in hands-on electrical hardware design, development, and troubleshooting in a fast-paced space or high-reliability environment
• Deep technical understanding of the Geostationary radiation environment and its specific degradation mechanisms on electronic components (TID, SEE, DDD)
• Expert-level experience in testing, debugging, and analyzing complex analog, digital, and mixed-signal circuits using standard lab equipment
• Demonstrated experience leading technical projects and managing the risk profile of high-reliability electrical hardware systems
• Experience delivering flight-qualified, mission-critical electrical designs for space radiation environments
• Background in electromagnetic design and its interaction with radiation environments
• Established relationships with radiation test facilities and experience directing heavy-ion or proton testing campaigns
• High proficiency with ECAD tools for schematic capture and PCB layout (e.g., Altium Designer) and familiarity with MCAD workflows (Solidworks)
