Company mission
To bring one of the world's first factory-constructed microreactors to market.
Role
Who you are
- 5+ years of data engineering or software engineering experience
- Python and SQL proficiency—you'll write both daily
- Experience with data warehouses—Databricks, Snowflake, BigQuery, or Redshift
- ETL/ELT pipeline development—Fivetran, Airbyte, Stitch, or custom pipeline experience
- API integration experience—REST, GraphQL; you're comfortable reading API docs and building integrations with enterprise SaaS tools
- Data modeling skills—dimensional modeling, schema design, understanding of how data will be used downstream
- This position requires the ability to work in the United States and eligibility for access to export-controlled information under ITAR/EAR
Desirable
- Background in hardware or hardtech companies—you understand manufacturing, supply chain, and physical product development
- Experience with dbt (data build tool)
- Experience with data quality frameworks and testing (Great Expectations, dbt tests, etc.)
- Comfortable building lightweight internal tools—Python/Flask, basic frontend—or using AI coding assistants (Cursor, Copilot) to extend your capabilities
- Familiarity with MES, ERP, or supply chain systems (ION, SAP, NetSuite, etc.)
What the job involves
- We're building a new team to own Radiant's internal data infrastructure, executive analytics, and AI capabilities
- As a Staff Data Platform Engineer, you'll be hands-on building the integrations and pipelines that connect Radiant's operational systems—Finance, HR, Supply Chain, Manufacturing, and Recruiting—into a unified data platform
- Your first priority will be the ION-Ramp integration: building the pipeline that enables three-way matching (PO + Receipt + Invoice) between our manufacturing execution system and payments platform
- This directly reduces manual work for the Finance team
- From there, you'll expand to connect 9 enterprise systems, build dbt transformation models, and ensure data quality across the platform
- Build integrations: Configure Fivetran connectors, build custom pipelines, and connect 9 enterprise systems (ION, Ramp, QuickBooks, Rippling, Ashby, Salesforce, SharePoint, Smartsheet, DocuSign)
- Develop the ION-Ramp pipeline: Build the Snowflake → Databricks → Ramp pipeline that enables three-way matching for Finance
- Write dbt models: Transform raw data into clean, documented, tested models for dashboards and analytics
- Ensure data quality: Implement testing, monitoring, and alerting for data pipelines; catch issues before they reach dashboards
- Support dashboards: Work with the PM and stakeholders to ensure the data models support Finance, Operations, and HR/Recruiting dashboards
- Document everything: Maintain clear documentation for pipelines, models, and data definitions
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.
