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. 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 Radiation Effects Engineer, you will be responsible for driving the electrical survivability of our spacecraft by analyzing, designing, and testing robust electronic systems. This position requires hands-on experience in circuit design, component validation, and mitigating radiation effects for harsh aerospace environments.
- Support the electrical architecture and design of fault-tolerant systems optimized for radiation environments
- Actively participate in core electrical design, schematic capture, PCB layout reviews, hardware bring-up, and laboratory testing
- Coordinate and execute electrical radiation testing campaigns to upscreen COTS and automotive-grade components
- Develop fault-tolerant systems & operations into the spacecraft by working closely with the rest of the team
- Assist in recruiting and hiring additional teammates to our rapidly-growing team
- Bachelor of Science degree in Electrical Engineering (EE), or a related technical field (Physics, Nuclear Engineering) with a focus on electronics
- A passion for hardware development, including hands-on electrical circuit design, prototyping, and troubleshooting in a fast-paced environment
- Strong foundation in electrical design principles, including component selection, power distribution, and signal integrity
- Direct experience analyzing, designing, and testing electronic circuits for radiation effects
- Experience in testing and debugging complex analog, digital, and mixed-signal circuits using standard lab equipment (oscilloscopes, spectrum analyzers, etc.)
- Experience engineering fault-tolerant, high-reliability electrical hardware architectures
- US Citizenship or Green Card
- Experience testing electrical designs for space or high-radiation environments
- Advanced understanding of semiconductor physics and radiation interactions
- Experience configuring electrical test setups and running measurement campaigns at radiation test facilities
- Proficiency with ECAD tools for schematic capture and PCB layout (e.g., Altium Designer) and familiarity with MCAD (Solidworks)
Base pay is just one component of Astranis’s total rewards package. Your compensation also includes a significant equity package via incentive stock options, high-quality company-subsidized healthcare, disability and life insurance, 401(k) retirement planning, flexible PTO, and free on-site catered meals.
