Company mission
To bring one of the world's first factory-constructed microreactors to market.
Role
Who you are
- Bachelor's degree in computer science, engineering, or a related technical field
- 8+ years of professional experience in DevOps, Site Reliability, Infrastructure, or Platform Engineering
- Expert-level proficiency in programming languages such as Python, Golang, Rust, C#, or C/C++
- Expert-level proficiency with Kubernetes and Docker for orchestration and deployment
- Experience with Git and CI/CD tools (Argo, GitLab CI, Jenkins, GitHub Actions), designing automated build, test, and deployment pipelines
- Strong coding skills, developing automation and monitoring tools, internal applications, and infrastructure software
Desirable
- Experience deploying and maintaining cloud-native applications in production, including hands-on work with microservices, architectures, service mesh technologies, and distributed systems
- Familiarity with infrastructure monitoring and observability tools like Datadog, Grafana, InfluxDB, Prometheus, Nagios, etc
- Working experience in secrets management, Identity and access management, network security, vulnerability scanning, etc
- Experience in highly regulated industries (aerospace, defense, automotive, nuclear, or medical devices)
- Passion for clean, maintainable code and building automation that enhances developer productivity and accelerates engineering velocity
- Experience working cross-functionally with engineering teams in different disciplines such as mechanical, electrical, materials, and nuclear
What the job involves
- Radiant is seeking a driven Senior DevOps Engineer to lead software infrastructure, deployment, and automation projects
- In this role, you will collaborate across the entire org and work closely with the software team to design scalable, secure, and resilient DevOps practices, tools, and systems
- The infrastructure you manage, pipelines you build, and analysis tools you design and maintain will be used to design, run, and analyze the first new reactor design in 50 years, and you will have the opportunity to build a strong foundation for production
- Architect, implement, and maintain infrastructure across AWS and on-premises Linux environments, ensuring high availability, security, and performance for mission-critical systems
- Own and optimize Kubernetes and Docker container orchestration to run simulations, internal tools, and engineering applications at scale
- Design, build, and optimize CI/CD pipelines using Git, Argo, and other automation tools to enable rapid, reliable software delivery across engineering teams
- Develop internal tools supporting build systems, testing frameworks, deployment automation, and developer environments
- Develop computational analysis tools for the digital twin platform, implementing automated profiling and monitoring to optimize HPC workloads for reactor modeling
- Implement and manage infrastructure-as-code practices using Terraform or similar tools to ensure reproducible, version-controlled infrastructure deployments
- Establish and maintain observability, monitoring, and logging infrastructure to ensure system reliability and enable rapid incident response
- Design and maintain high-performance networking infrastructure for distributed simulation systems, optimizing data transfer between HPC clusters
- Work across engineering teams to understand infrastructure requirements and eliminate bottlenecks that impact development velocity
- Must be willing to work extended hours and weekends as necessary to accomplish our mission
- Must work 100% onsite at El Segundo HQ
Our take
To support the clean energy revolution, Radiant Nuclear is developing a portable, containerised nuclear microreactor. Once launched, it will have the potential to provide power to remote parts of the world or act as a backup supply to vital infrastructure such as hospitals and data centres.
Typically, these backup systems are powered by diesel generators - making them extremely bad for the environment. Radiant's microreactors could allow the replacement of these generators whilst supplying the same critical asset support, enabling a substantial reduction in carbon footprint.
Having completed the design phase of the project, Radiant has taken a step closer towards realising its portable microreactor (known as Kaleidos). On the back of impressive Series D funding, the company intends to test a prototype as early as mid-2026 and has secured considerable funding to support its work towards that goal.
