Gasification Engineer

Arbor is a team of engineers, scientists, and builders focused on creating the next generation of clean energy systems. Our work combines high-efficiency turbomachinery, advanced combustion, and modular design to deliver zero-emission, fuel-flexible power at scale. We’ve drawn from aerospace and industrial expertise to meet the challenge of surging electricity demand—and to offer a solution that installs faster, performs better, and costs less than conventional alternatives. We’re designing energy systems that can evolve with the world’s needs.

We’re looking for a Gasification Engineer to take ownership of the development, testing, and optimization of our biomass gasification reactor as we scale from demonstration to pilot and beyond. As a core member of a small, hands-on combustion team, you’ll guide daily operations, execute performance testing, and lead design improvements to ensure safe, reliable, and high-performing systems.

Responsibilities

• Serve as technical lead for the biomass gasification reactor, owning design, build, operation, and iteration
• Conduct and lead test campaigns, including planning, execution, and data analysis
• Operate and troubleshoot the gasification reactor during daily testing and development
• Guide system configuration and performance optimization efforts
• Own and execute feedstock sensitivity studies to assess system flexibility and robustness
• Drive continuous improvement through design changes and upgrades
• Collaborate cross-functionally to support system integration and scale-up
• Ensure safe operation of high-temperature, high-pressure thermochemical equipment
  
  
  

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
• Hands-on experience with high-temperature and pressure equipment
• Demonstrated ability to own product lifecycle from conceptual design to validation
• Willing to travel (up to 20%) to the test site in San Bernardino, CA, for operational activities and builds
  
  
  

Preferred Qualifications

• Advanced degree (M.S. or Ph.D.) with a focus on combustion science or energy systems
• Experience with supercritical CO₂ or high-pressure combustion systems
• Familiarity with low-emissions combustion strategies, such as lean premixed combustion or staged combustion
• Knowledge of chemical kinetics and fuel property effects on combustion behavior
• Proficiency in combustion modeling tools (e.g., CHEMKIN, Cantera, Fluent, or OpenFOAM)
• Programming or scripting skills for data reduction and automation (Python, MATLAB, etc.)
• Experience working in startup or experimental R&D environments
  
  
  

Benefits

• 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!
