At Arbor Energy & Resources Corporation ("Arbor Energy"), 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 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.
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.
- 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
- 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
- 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
- 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!

What We Do
At Arbor, we’re sustainably powering the present while erasing emissions of the past. Our innovative system transforms organic waste into clean, reliable electricity while capturing carbon dioxide at scale. Founded by space tech veterans who pivoted from building technology to explore new planets to protecting our own, Arbor leverages cutting-edge aerospace technology to tackle climate change. Our mission is to bring gigawatts of clean, dependable baseload power online while removing gigatons of legacy carbon emissions. Earth is the most important spaceship we’ll ever have, and we’re dedicated to restoring its balance. Drawing on our team’s deep aerospace expertise, we’ve created a power system that meets today’s demands while repairing yesterday’s damage. Arbor’s engine, fueled by organic waste, improves on Bioenergy with Carbon Capture and Storage (BECCS) using advancements in oxy-combustion, supercritical turbomachinery, and additive manufacturing. The system turns waste—like overgrown brush, crop residues, and food waste—into clean power, reducing wildfire risks and landfill emissions. The captured CO2 is permanently stored deep underground, where it mineralizes into rock, ensuring it never returns to the atmosphere. At Arbor, we envision a future where human progress and environmental stewardship work in harmony to power our world and bring the planet into balance. We’re proudly backed by climate-focused investors including Gigascale Capital, Voyager Ventures, Lowercarbon Capital, and Cantos Ventures.
