Arborenergy Sr. Combustion Engineer (Syngas Oxyfuel) at Arborenergy pioneers rocket-derived, high-pressure combustion systems for carbon-negative power cycles. The role involves taking syngas oxy-combustion from lab-scale to implementation and developing fuel-flexible combustors.

Responsibilities

The Sr. Combustion Engineer (Syngas Oxyfuel) helps pioneer our rocket-derived, high-pressure combustion systems for carbon-negative power cycles, burning our biomass-produced syngas in a high efficiency combustor. In this role, you’ll take syngas oxy-combustion from lab-scale characterization to implementation running off of gasifier syngas within a year and carry what you learn into the development of fuel-flexible combustors at the heart of our commercial product. You will partner closely with test engineers, analysts, and designers to push boundaries—delivering breakthrough performance that powers a sustainable future.
From conceptual design and modeling to hands-on testing and rapid iteration, you'll own the full hardware lifecycle.
This is an onsite opportunity in our El Segundo, CA office.
Develop the kinetics that the envelope demands: reduced H2/CO/CO2 mechanisms, flame-speed, autoignition and blowout limits across composition; anchor models to hot-fire data
Plan, execute, and analyze high-pressure and temperature test campaigns, delivering actionable insights to accelerate progress
Own rapid hardware development cycles—from manufacturing and assembly through testing and iterative improvements
Leverage additive manufacturing and state-of-the-art simulation tools to accelerate innovation and reduce development timelines
