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 share our values and are drawn to rigorous work with lasting impact, we’d love to learn more about you. Come build what the future will run on.
Steward our planet: We build for tomorrow, ensuring every bolt we tighten and every hand we lend leaves our environment stronger than we found it.
Lead with Love: We champion the success of our people, partners, and planet, nurturing excellence through camaraderie and rigor.
Explore the Uncharted: We embrace the unknown with curiosity, using courage and discipline to transform uncertainty into opportunity.
Role Overview
The Sr. Combustion Engineer (Syngas Oxyfuel) helps pioneer our rocket-derived, high-pressure combustion systems for carbon-negative power cycles, burning our biomass-produced syngas in a high efficiency combustor. In this role, you’ll take syngas oxy-combustion from lab-scale characterization to implementation running off of gasifier syngas within a year and carry what you learn into the development of fuel-flexible combustors at the heart of our commercial product. You will partner closely with test engineers, analysts, and designers to push boundaries—delivering breakthrough performance that powers a sustainable future.
From conceptual design and modeling to hands-on testing and rapid iteration, you'll own the full hardware lifecycle.
Responsibilities
- Develop the kinetics that the envelope demands: reduced H₂/CO/CO₂ mechanisms, flame-speed, autoignition and blowout limits across composition; anchor models to hot-fire data
- Plan, execute, and analyze high-pressure and temperature test campaigns, delivering actionable insights to accelerate progress
- Own rapid hardware development cycles—from manufacturing and assembly through testing and iterative improvements
- Leverage additive manufacturing and state-of-the-art simulation tools to accelerate innovation and reduce development timelines
Requirements
- Bachelor’s degree in Mechanical, Aerospace, Chemical engineering, or related field
- 5+ years of experience in combustion system design, analysis, and testing
- Strong understanding of thermodynamics, fluid mechanics, and heat transfer
- Comfort in high-pressure / real-fluid combustion (supercritical reactants, CO₂ dilution) and/or a demonstrated track record of ramping into an unfamiliar regime fast
- Curious, inventive, and entrepreneurial mindset comfortable driving progress
Preferred Qualifications
- Advanced degree (M.S. or Ph.D.) in Mechanical, Aerospace or Chemical engineering
- Hands-on experience with hot-fire testing and high-pressure systems in rocket or gas turbine environments
- Programming or scripting skills for data reduction and automation (Python, MATLAB, etc.)
- Background in startup environments or agile hardware development cycles
Benefits & Compensation
- Pre-IPO 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
- 12+ company holidays, including Earth Day!
- 401(k)
- Commuter benefits
- Annual learning and development stipend
- And more!

Arbor designs high-performance energy systems to power a livable, abundant future. Our compact turbine system HALCYON delivers carbon-neutral baseload power with zero operating emissions. Each 25 megawatt (MW) unit combines oxy-combustion and supercritical CO₂ technology for high thermal efficiency, a small footprint, and rapid deployment. It’s fuel-flexible by design, able to run on natural gas today, and in time, on carbon-negative fuels like organic waste. HALCYON systems can run independently or be linked together into 100 MW+ plants, meeting the urgent need for clean, firm power in the places legacy suppliers have left behind. Founded by aerospace engineers and systems thinkers, Arbor brings deep experience from rocket propulsion and turbomachinery to the urgent work of sustaining life on Earth. We believe the tools we build today should serve generations to come—and that progress, done right, can be both powerful and restorative. If you’re ready to build systems that matter alongside kind, curious people committed to doing meaningful work well, we’d love to hear from you. We’re backed by leading climate investors including Gigascale Capital, Voyager Ventures, Lowercarbon Capital, and Cantos Ventures.
