- Partner with design engineers to develop innovative production methods for complex mechanisms and structures
- Develop, qualify, and refine manufacturing processes to meet all design and business requirements including safety, quality, efficiency, and delivery
- Develop and execute manufacturing specifications and fabrication instructions
- Manage manufacturing bill-of-materials (mBOM) for components and assemblies

Our take
To support the clean energy revolution, Radiant Nuclear is developing a portable, containerized 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 centers.
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 realizing its microreactor (known as Kaleidos). The company intends to test a prototype as early as mid-2026 and has secured considerable funding to support its work towards that goal.
