FPGA Engineer

Overview

About Radiant Radiant is an El Segundo, CA-based startup building the world’s first mass-produced, portable nuclear microreactors. The company’s first reactor, Kaleidos, is a 1-megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid-deploy capability can replace similar-sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases.

Radiant’s unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials. Founded in 2020, Radiant is on track to test its first reactor at the Idaho National Laboratory next year, with initial customer deliveries beginning in 2028.

FPGA Engineer Radiant is seeking a driven FPGA Engineer to join our Embedded Systems team. You will be responsible for designing, developing, and validating FPGAs used in the reactor instrumentation and control system for safety critical applications, sensor and actuator handling, and communication systems. This role requires working with hardware engineers, embedded software engineers, and test engineers in a cross-functional setting to develop cohesive designs that meet the demands of controlling and monitoring fission reactors.

You will be a key contributor in testing the first commercial reactor design in over 50 years.

• Own the design of sensor processing systems from concept to integration.
• Implement logic designs in VHDL.
• Integrate designs onto FPGA/SoC platforms.
• Write automated verification tests.
• Work directly with embedded software engineers to deliver complete products.
• Collaborate with cross-functional mechanical, software, and control teams.

• Bachelor’s degree in computer engineering, electrical engineering, or a related field.
• 5+ years of experience working with FPGAs.
• Knowledge of VHDL.
• Experience troubleshooting timing closure issues.
• Experience with multi-clock designs.
• Understanding of verification methodologies and frameworks.

• Experience with embedded C/C++.
• Experience with Microchip Polar Fire SoC platform
• Experience with Linux and bash shell scripting.
• Experience with Docker.
• Excellent documentation skills and ability to collaborate in multidisciplinary environments.

• Cross-functional team with embedded software, FPGA, and hardware all together.
• Opportunities for technical growth outside of pure software.
• Opportunity to own designs from concept to completion.

• Must be willing to work extended hours and weekends as necessary to accomplish our mission.
• Must work 100% onsite at El Segundo HQ.
