Role Overview
We are seeking a hands-on Turbomachinery Engineering Manager to lead the design, development, and delivery of rotating equipment for next-generation energy systems. This role requires a technically deep leader who thrives in a fast-paced, resource-constrained environment and is comfortable owning both the engineering details and team execution. You will lead a small-to-mid-sized team responsible for turbomachinery development—from early concept through detailed design, build, test, and productization.
Arbor’s team of world-class engineers and scientists are developing a scalable, low-cost approach to Bioenergy with Carbon Capture and Storage (BECCS) based on modern rocket engine technology. BECCS is a carbon dioxide removal (CDR) approach that uses biomass to produce energy and remove CO₂ from the atmosphere and store it permanently underground, while ensuring food security, rural livelihoods, and biodiversity are not affected. Our modular technology leverages the power density of supercritical CO2 to enable compact gasification, oxy-combustion, and high-pressure turbo-expansion to convert abundant waste biomass into clean electricity, water, and high-purity CO2, capturing and sequestering all emissions from the process. Our team brings together a passion for science, technology, and global stewardship to make low-cost, high-quality carbon removal and baseload power a reality.
Responsibilities

- Establish and maintain design processes, technical rigor, and documentation practices (e.g., design reviews, analysis workflows, validation plans)
- Work cross-functionally with systems, combustion, controls, manufacturing, and test teams to ensure successful integration
- Support hardware build, test execution, and troubleshooting—this is not a purely desk-based role
- Mentor and develop engineers, setting clear expectations while fostering a high-performance, ownership-driven culture
- Balance speed and rigor—making pragmatic decisions in an environment without large-company support structures
Requirements
- 10–15+ years of experience in turbomachinery or rotating equipment (e.g., compressors, turbines, pumps, expanders)

- Experience working in hands-on hardware environments (build, test, iterate)
- Ability to operate effectively in a “scrappy” environment with limited resources and evolving processes
- Strong systems thinking and ability to interface across multiple engineering functions
Preferred Qualifications
- Experience in small teams, startups, or skunkworks-style programs
- Background in high-speed turbomachinery, novel cycles (e.g., sCO₂, hydrogen), or tightly integrated systems
- Familiarity with design for manufacturability and supplier engagement
- Experience setting up or scaling engineering processes in a growing organization
- Prior ownership of a turbomachinery module or full machine
