We are seeking a Mechanical Design Engineer to design, develop, and oversee mechanical and electro-mechanical systems. In this role, you will use FEM software, CAD tools, and hand calculations to create and refine designs, generate technical drawings, and lead skilled technicians in building and testing systems. The ideal candidate has experience with hazardous systems, control systems, and industry standards like ASME and AISC.

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

Own the development of multiple mechanical and electro-mechanical systems
Use FEM software and hand calculations to design and build mechanical systems for energy generation.
Create drawings and work instructions for system design and construction.
Collaborate with and guide technicians in building and testing mechanical systems.
Improve and refine the mechanical systems under your responsibility.

Requirements

Bachelor’s degree in Mechanical or Aerospace Engineering.
3+ years of experience as a mechanical engineer.
Proficiency in CAD and FEA software.
Must work on-site at headquarters in El Segundo, CA.
Willing to travel (up to 20%) to the test site in San Bernardino, CA for operational activities and builds.

Preferred Qualifications
