Antares is building mass-producible, inherently safe, deployable microreactors for terrestrial, underwater, and space applications, with a mission to make clean energy abundant from Earth to the Asteroid Belt. The company has raised over $600M in venture capital and holds hundreds of millions in contracts with military services, NASA, and the Department of Energy. The team includes veterans from SpaceX, the White House, the Pentagon, the Department of Energy, MIT, and national laboratories.
As a Staff Turbomachinery Design Engineer, you will own turbomachinery hardware for Antares nuclear reactors from concept through development, qualification, and production. You will be a key member of the Reactor Hardware Team, responsible for the technical execution of complete turbomachines while coordinating analysis, design, manufacturing, test, and supplier activities to deliver hardware that meets program requirements and schedule.
Key responsibilities include:
- Own new and existing turbomachinery hardware through development and production
- Lead the design, analysis, build, and test of turbomachinery for Antares nuclear reactors
- Translate system requirements into turbomachinery requirements, interfaces, and verification plans
- Coordinate work across aerodynamics, mechanical design, structures, rotordynamics, bearings, thermal analysis, manufacturing, and test
- Define development and test plans that retire the highest technical risks early
- Work closely with external suppliers and Antares manufacturing, test, and quality engineers to deliver hardware on schedule
- Investigate issues during manufacturing and test, identify root causes, and drive corrective actions to closure
- Improve existing designs to increase reliability and manufacturability, reduce cost and lead time
- Lead design reviews and communicate technical status, risks, and decisions to engineering and program leadership
The ideal candidate is comfortable making engineering decisions with incomplete information, balancing performance, reliability, manufacturability, cost, risk, and schedule. You should be able to identify the work required to retire technical risk, delegate effectively to subject matter experts, and maintain ownership of the overall result. Experience taking complex mechanical designs from concept to production is essential.
Note: This role requires flexibility to support hardware development milestones, including occasional weekend or long-hour pushes. ITAR compliance is required; applicant must be a U.S. citizen, national, lawful permanent resident, Refugee, or Asylee, or be eligible to obtain required authorizations from the U.S. Department of State.
QUALIFICATIONS:
Required:
- Bachelor's degree in Mechanical, Aerospace, or related engineering discipline
- 7+ years of full-cycle design engineering experience
- Experience releasing production-intent mechanical drawings and models for fabrication, including GD&T and tolerance stack-up
- Working knowledge of turbomachinery and high-speed rotating machinery
- Experience making engineering tradeoffs involving performance, manufacturability, cost, risk, and schedule
- Demonstrated ability to break down complex engineering problems, prioritize work, and drive technical issues to closure
- Ability to coordinate and delegate technical work while maintaining ownership of the complete hardware
Preferred:
- Master's degree in Mechanical, Aerospace, or related engineering discipline
- 8+ years of experience in design and ownership of turbomachinery
- Experience serving as a responsible engineer, design owner, technical lead, or equivalent role for complex hardware
- Experience working directly with suppliers and manufacturing teams to resolve design and production issues
- Experience in a demanding, fast-paced development environment
- Proficiency with NX for CAD design, drafting, and GD&T
- Proficiency with ANSYS Mechanical and CFX
