About the job
At Arbor, we’re creating technology to power our lives while protecting the planet that sustains them. Our advanced power systems deliver clean, reliable baseload electricity with zero operating emissions—modular, fuel-flexible, and engineered for the realities of today’s energy demand. At the core is a supercritical CO₂ turbine with integrated carbon capture, designed to bring carbon-neutral power online quickly at meaningful scale.
Our team includes aerospace engineers, combustion experts, and systems thinkers with a shared goal: to build technology worthy of the world we want to live in. While many of us began our journeys looking to the stars, we’re applying that expertise here at home to deliver dependable, emission-free baseload power and a future of lasting abundance.
If you’re drawn to rigorous work with lasting impact, we’d love to hear from you. Come build what the future will run on.
We are seeking a Sr. Mechanical Design Engineer to lead the design and analysis of rotors and casings for turbomachinery in a supercritical CO₂-based power cycle. This role involves conceptual design, assembly architecture selection, material selection, and structural analysis, ensuring high-performance, reliable operation under demanding conditions. The ideal candidate has expertise in bolted joint and seal design, finite element analysis (FEA), and thermomechanical analysis, with preferred experience in creep analysis and rotordynamics.
Responsibilities
- Design and optimize rotors and/or casings for high-performance turbomachinery using NX.
- Select assembly architectures and materials to meet performance and reliability requirements.
- Size and analyze bolted joints, seals, and piping flanges for structural integrity.
- Perform static and transient thermomechanical analysis using ANSYS.
- Conduct modal analysis of both stationary and rotating systems to evaluate dynamic behavior.
- Perform thermal analysis to assess the effects of temperature gradients and thermal expansion.
- Ensure designs meet operational, thermal, and mechanical performance requirements.
- Collaborate with combustion and systems teams.
- Support manufacturing, assembly, and testing efforts to validate designs.
Requirements
- Bachelor’s degree in Mechanical, Aerospace, or a related Engineering field.
- 5+ years of experience in turbomachinery design or mechanical system engineering.
- Proficiency in ANSYS FEM software for stress, thermal, and thermomechanical analysis.
- Strong understanding of bolted joint, seal, and flange design.
- Experience with static, transient, and thermal structural analysis of rotating systems.
- Familiarity with materials selection for high-stress and high-temperature applications.
Preferred Qualifications
- Experience in creep analysis for high-temperature applications.
- Knowledge of rotordynamics and vibration analysis of rotating machinery.
- Familiarity with bearing design, damping, and balancing of rotating components.
- Experience working with supercritical CO₂ or high-density working fluids.
- Proficiency in NX CAD software
- Experience in startup or R&D environments.
Benefits
- Stock options
- Medical, dental, and vision insurance (Arbor covers 90% for employees)
- Basic life insurance fully covered
- Health savings account (HSA) with matching
- Flexible savings account (FSA)
- Unlimited PTO
