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. Astranis has raised over $750 million from some of the world’s best investors, from Andreessen Horowitz to Blackrock and Fidelity, and employs a team of 450 engineers and entrepreneurs. Astranis designs, builds, and operates its satellites out of its 153,000 sq. ft. headquarters in Northern California, USA.

As a Senior Radiation Effects Engineer, you will support the radiation hardness assurance (RHA) strategy. You will be responsible for defining the environmental requirements, leading circuit-level mitigation designs, and overseeing advanced testing to ensure our electrical systems survive the harshest orbits. 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.

Architect and design fault-tolerant, radiation-hardened electrical systems and avionics architectures capable of operating reliably in high-radiation environments
Lead simulation and modeling to evaluate GTO and GEO radiation effects
Establish methodologies and drive radiation testing campaigns to upscreen and qualify commercial off-the-shelf (COTS) and automotive-grade electrical components
Collaborate cross-functionally with mechanical and structural teams to run 3D ray-tracing simulations (e.g., FASTRAD) and optimize shielding levels versus mass trade-offs for sensitive electrical assemblies
Provide technical mentorship to junior engineers and support 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
