Staff Reactor Systems Engineer at Radiant Industries · LumiJobs

Responsibilities

We are seeking a Staff Reactor Systems Engineer to own the technical integration of a first-of-a-kind reactor. With no operating predecessor to copy and no mature supply chain, you will be the person who holds the whole machine together, making sure hundreds of design decisions across nuclear physics, thermal-hydraulics, controls, structures, materials, fuel, and licensing add up to a reactor that works safely and is delivered to customers on time.
As a staff-level engineer, you will work across every engineering discipline, resolve the hardest cross-system tradeoffs, and set the systems engineering practices the team uses as Kaleidos moves from first-of-a-kind builds to scaled production. You will be instrumental in unlocking commercialization of the first mass-produced nuclear reactor.
Own the Kaleidos system architecture and serve as technical authority for integrated system performance, safety, and reliability.
Define and manage system budgets (e.g., thermal, mass, power, reactivity, and volume) and allocate margins across subsystems.
Own interface definitions and interface control documents between subsystems, including reactor core, primary loop, power conversion loop, shielding, controls, and structures.
Maintain the technical baseline (requirements, configuration, change control, risk registers, and documentation) using lightweight processes scaled to a fast-moving startup.
Identify cross-cutting risks early and drive them to resolution before they become safety or schedule problems.
Define the verification and validation strategy and partner with Test Engineering to turn requirements into test plans, success criteria, and acceptance tests.
Correlate analysis and test results against system requirements, and drive resolution of discrepancies.
Support safety-basis and licensing or regulatory documentation as needed.
Mentor engineers across the organization in systems thinking, requirements quality, and interface discipline.
Communicate system status, risks, and tradeoffs clearly to engineering and program leadership.
