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 failsafe microreactor that can be transported anywhere power is needed and run for up to five years without the need to refuel. 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 utilizes modern software engineering to rapidly achieve safe, factory-built microreactors that leverage existing, well-qualified materials. Founded in 2020, Radiant is on track to test its first reactor next year at the Idaho National Laboratory, with initial customer deliveries beginning in 2028.
We're building a new team to own Radiant's internal data infrastructure, executive analytics, and AI capabilities. As the Staff DevOps Engineer, you'll own the infrastructure that powers our data platform—ensuring reliability, security, and scalability for the systems that connect Finance, HR, Supply Chain, and Recruiting.
You'll work closely with the Software Engineering team on shared Databricks infrastructure, ensuring that operational analytics and reactor simulation workloads coexist smoothly. You'll also own CI/CD pipelines, monitoring, and security compliance for our data systems.
What You'll Do- Own infrastructure: Deploy and manage Databricks, Fivetran, Airbyte, and supporting infrastructure on AWS
- Administer Databricks: Manage workspaces, clusters, Unity Catalog, and SQL Warehouses (shared responsibility with SWE team)
- Build CI/CD pipelines: Automate deployments for dbt models, connector configurations, and dashboard updates
- Monitor and alert: Set up Datadog (or similar) for pipeline monitoring, data quality alerts, and infrastructure health
- Ensure security compliance: Implement infrastructure that meets ITAR/EAR requirements; work with IT/Security on access controls, audit logging, and network configuration
- Support the team: Enable Data Platform Engineers to ship quickly with reliable, well-documented infrastructure
- 7+ years of DevOps or infrastructure engineering experience
- AWS experience—EC2, S3, IAM, VPC, and related services (Radiant is AWS-based)
- CI/CD pipeline development—GitHub Actions, GitLab CI, or similar
- Infrastructure as code—Terraform, CloudFormation, or Pulumi
- Scripting and automation—Python, Bash, or similar
- Databricks administration experience—workspaces, clusters, Unity Catalog, SQL Warehouses
- Experience in regulated environments—SOC 2, FedRAMP, ITAR, or similar compliance frameworks
- Experience with data pipeline monitoring and observability (Datadog, Monte Carlo, etc.)
- Familiarity with Fivetran, Airbyte, or similar data integration tools
- Experience supporting data engineering or analytics teams
- Mission: Clean energy that can go anywhere—few problems matter more
- Team: Work alongside exceptional people from SpaceX, Blue Origin, and other top engineering organizations
- Compensation: Competitive compensation with equity
- Benefits: Health/dental/vision, 401(k), and flexible PTO
- Ownership: You'll own the infrastructure for a critical new team—not maintaining someone else's system
- Modern stack: Databricks, Fivetran, dbt, Datadog—best-in-class tools
This position requires the ability to work in the United States and eligibility for access to export-controlled information under ITAR/EAR.

What We Do
Radiant is a clean energy startup building a nuclear microreactor. A climate-friendly alternative to diesel generators, Radiant's Kaleidos 1MW microreactor will be the world's first portable, zero-emissions power source that works anywhere. We plan to test our development reactor by 2026 and if successful, it will be the first new commercial reactor design to achieve a fueled test in over 50 years. Our microreactor can bring power to remote parts of the world and provide backup power for life-saving applications in hospitals or disaster-relief scenarios.
Why Work With Us
Our world-class team has prior experience in complex hardware development from SpaceX, McMaster, The Boring Company, and renowned national laboratories that define our mentality to radically improve our microreactors. We care deeply about our mission to reduce carbon emissions, and have fun while doing so from trivia nights to ski retreats.
