Mechanical Design Engineer (Combustion) (El Segundo)

Mechanical Design Engineer (Combustion)

We are seeking a Mechanical Design Engineer for our Combustion team to own the 3D design of high-temperature, high-pressure hardware from concept through fabrication. You'll collaborate closely with combustion engineers, analysts, and test engineers to develop practical, test-ready systems. Your work will leverage metal additive manufacturing, precision machining, and algorithmic design techniques to push the boundaries of modern fabrication.

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 CO? 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

• Lead detailed 3D modeling of complex components and assemblies.
• Apply Design for Additive Manufacturing (DfAM) principles to optimize performance, cost, and manufacturability.
• Create complete drawing packages with GD&T, assembly documentation, and bill of materials (BOMs).
• Translate engineering requirements into practical, buildable designs.
• Generate work instructions and collaborate with technicians during builds and test campaigns.
• Continuously iterate based on feedback from analysis, testing, and fabrication.
