Senior Turbomachinery Engineer - Nuclear

Senior Turbomachinery Engineer - Help Build the Future of Nuclear Power!

Opportunity Summary

A fast-growing, venture-backed energy technology startup is building a first-of-its-kind compact, zero-emissions power solution designed for remote locations, disaster relief zones, and critical infrastructure. The company is on track to perform one of the first fueled tests of a new commercial nuclear design in over half a century and is poised to revolutionize portable energy. As a Senior Turbomachinery Engineer, you'll take full ownership of a helium circulator central to the reactor's primary loop. From early design concepts and hardware selection to testing and system integration, you'll lead the development of a high-pressure, high-temperature turbomachinery system that directly supports upcoming demonstration and production units. This is a rare opportunity to contribute to a generational leap in energy systems by building foundational hardware in an agile, high-impact environment.

About Us

We're a deep-tech company focused on building the world's first factory-produced nuclear microreactors. Our core mission is to replace carbon-heavy power systems in remote and off-grid settings with reliable, safe, and clean nuclear energy. Our team includes experienced engineers and scientists from top aerospace, energy, and defense backgrounds, united by a commitment to bold innovation and a practical path to commercialization.

Job Duties

• Lead the end-to-end development of helium circulator turbomachinery for the reactor's primary system
• Design, assemble, and test high-performance hardware capable of withstanding extreme thermal and pressure conditions
• Manage supplier relationships to ensure timely component delivery and integration
• Conduct thermodynamic, fluid dynamic, and structural analyses to inform design decisions using hand calcs and simulation tools
• Run trade studies balancing performance, cost, mass, and manufacturability
• Develop manufacturing instructions, assembly documentation, and test procedures
• Maintain and manage detailed Bills of Materials (BOM)
• Oversee risk mitigation activities including FMEA and subsystem reliability assessments
• Interface with cross-functional teams to align system-level requirements and technical goals

Qualifications

• B.S. in Mechanical or Aerospace Engineering from an accredited institution
• 5+ years of professional experience designing, building, and testing turbomachinery systems
• Strong command of turbomachinery principles including blade design, rotordynamics, and pressure vessel constraints
• Demonstrated experience taking hardware from concept through prototyping and testing
• Proficiency in fluid modeling techniques for both compressible and incompressible flows
• Familiarity with manufacturing methods relevant to high-precision rotating machinery
• Excellent communication and documentation skills across technical disciplines
• High sense of ownership, independence, and attention to detail
• Prior nuclear experience is not required
