Company mission
To bring one of the world's first factory-constructed microreactors to market.
Role
Who you are
- 10+ years of software or data engineering experience, including hands-on AI/ML work
- Deep understanding of the AI landscape—you can evaluate vendor tools, understand RAG architectures, and advise on build-vs-buy tradeoffs
- Data platform architecture experience—you've designed and built systems on Databricks, Snowflake, or similar
- Strong technical leadership—you can set direction, mentor engineers, and interface effectively with non-technical stakeholders
- Hands-on ability—you're a player-coach who can write code when needed, not just draw diagrams
Desirable
- Background in hardware, aerospace, or defense—you understand manufacturing data, supply chain systems, and the complexity of physical product development
- Experience shipping AI products or building AI capabilities at a company (not just research)
- Experience with data integration tools (Fivetran, Airbyte, dbt)
- Experience in regulated environments (SOC 2, FedRAMP, ITAR)
- Familiarity with BI/analytics tools (Looker, Tableau, Power BI, Databricks dashboards)
What the job involves
- We're building a new team to own Radiant's internal data infrastructure, executive analytics, and AI capabilities
- As the Technical Lead (Director), you'll set the technical direction for the team—architecting the data platform, owning the AI strategy, and ensuring we make the right build-vs-buy decisions
- This is a player-coach role
- You'll lead technical direction and mentor engineers, but you'll also go hands-on when needed
- You'll own the AI vendor evaluation process, which is critical given our ITAR/EAR security requirements—standard AI tools don't work out of the box, and we need someone who can navigate the landscape and find compliant solutions
- Set technical direction: Define the architecture for our data platform (Databricks, Fivetran, dbt) and AI tooling; make build-vs-buy decisions
- Own AI strategy: Evaluate and select AI platforms (chatbot, enterprise search, specialized tools) that meet security requirements; lead RAG evaluation in H2
- Lead technical delivery: Ensure the ION-Ramp integration, dashboards, and AI tools are built correctly; hands-on when needed
- Mentor engineers: Set the technical bar for hiring; develop the DevOps and Data Platform Engineers on the team
- Interface with SWE: Coordinate with the Software Engineering team on shared Databricks infrastructure; ensure operational and engineering workloads coexist
- Navigate security: Work with IT/Security to ensure all technical decisions meet ITAR/EAR compliance requirements
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.
