Sr. Mechanical Design Engineer (Turbomachinery)

Job Description

Job Description

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.
