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.
We’re seeking a Mechatronics Engineer to drive the design, development, and optimization of high-pressure solids feed and removal systems—critical systems enabling reliable biomass delivery and ash management in our novel high-pressure gasification platform for carbon-negative power cycles.
In this role, you’ll own end-to-end development of robust, high-reliability solids handling hardware in a fast-paced, collaborative startup environment. From conceptual design and mechatronic integration through prototyping, testing, rapid iteration, and validation, you’ll deliver solutions that ensure continuous, clog-free operation under extreme pressure and temperature conditions.
You’ll collaborate closely with gasification, test, and controls engineers, providing technical expertise on critical decisions to accelerate progress while maximizing system uptime, flexibility, and overall carbon impact.
Responsibilities- Own the design, analysis, and integration of high-pressure solids feed (e.g., lock hoppers, screw feeders) and removal (e.g., ash extraction, filtration) systems
- Develop mechatronic solutions combining mechanical design, actuation, sensing, and control logic for reliable solids transport in harsh environments
- Perform sizing calculations, 3D modeling, structural/FEA analysis, and flow modeling for solids handling components and assemblies
- Plan, execute, and analyze solids flow tests and integrated high-pressure test campaigns, driving rapid learning and iteration
- Lead hardware development cycles—from detailed design and procurement through manufacturing, assembly, commissioning, and performance upgrades
- Leverage additive manufacturing, modern actuators/sensors, and automation tools to accelerate innovation and improve system robustness
- Propose and implement continuous improvements to eliminate bottlenecks, enhance safety, and increase operational reliability
- Bachelor’s degree in Mechanical, Mechatronics, Aerospace Engineering, or related field
- 3+ years of hands-on experience designing, building, and testing solids handling, feeding, or conveyance systems (preferably under high pressure/temperature)
- Strong expertise in mechanical design, actuation, sensing, controls integration, and materials selection for abrasive/corrosive environments
- Proficiency with 3D CAD (SolidWorks/NX preferred), FEA, and GD&T; experience generating fabrication drawings and BOMs
- Proven ability to own technical development of complex hardware from concept through validation in fast-paced settings
- Demonstrated track record of delivering reliable mechatronic systems with minimal downtime
- Curious, inventive, and entrepreneurial mindset—thrives in ambiguity and drives practical solutions forward
- Advanced degree (M.S. or Ph.D.) in Mechanical or Mechatronics Engineering
- Experience with high-pressure systems in rocket propulsion, gasifiers, pneumatic conveying, lock hopper systems, or similar
- Hands-on experience integrating PLCs, sensors, and control loops for automation
- Proficiency in programming/scripting for data analysis, automation, or control (Python, MATLAB, Ladder Logic, etc.)
- Background in startup or agile hardware development environments
- 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!
Base Pay: $130,000 - $150,000 USD/year. The salary is subject to the applicant's skills, qualifications, experience, and geographic location.

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.
