Mechanical Design Engineer (Combustion)

Arbor Energy•El Segundo, CA

10d•$130,000 - $150,000

About The Position

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.

Requirements

Bachelor’s degree in Mechanical, Aerospace, or a related Engineering discipline.
3+ years of experience in mechanical design of high-performance systems.
Proficiency in CAD software (Siemens NX preferred; others such as SolidWorks or Creo also acceptable).
Experience producing fully detailed drawing packages including GD&T and manufacturing specs.
Experience with additive manufacturing and DfAM principles.
Understanding of additive constraints: overhang angles, support strategy, build orientation, powder removal, etc.

Nice To Haves

Exposure to material behavior and surface finish considerations in high-temperature AM alloys (e.g., Inconel 625/718, Hastelloy, Haynes).
Familiarity with FEA or fluid/thermal analysis workflows.
Prior experience in a fast-paced, hands-on R&D or startup environment.
Exposure to combustion systems, high-temperature materials, or pressure vessels.

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.
