Company Overview:
Oleo is an early-stage biomanufacturing company developing a platform to produce carbon-negative oil feedstocks for advanced fuel production. Our technology combines microwave hydrolysis and microbial fermentation to convert biomass waste into oil feedstocks, addressing a $21B market. Oleo’s platform reduces cost exposure and improves supply chain stability for energy producers, with a targeted ~22% cost reduction compared to incumbent seed oils. This technology was developed by Oleo’s founders at Stanford University and is in the process of being scaled to the 300L setting at Lawrence Berkeley National Laboratory. Oleo is supported by Activate, DOE Leep @ Cyclotron Road, and BEAM Circular, and has received investment from Gener8tor, Safar Partners, Alpine Social Ventures, Collab Fund, and G-Force.
Role Description:
As the Mechanical Engineer, you will design and build the custom microwave applicator housing and biomass slurry delivery system required to operate at industrial throughput. You will translate RF design requirements into a manufacturable, robust reactor system capable of handling abrasive, high-solids biomass slurries at scale.
This is a hands-on role spanning design, prototyping, fabrication oversight, and commissioning.
Primary Responsibilities of this Role Include:
Design and engineer a custom microwave applicator vessel based on RF requirements
Develop a continuous biomass slurry delivery system capable of 600 kg/hr throughput
Design pumping, mixing, and flow control systems for high-solids biomass slurries
Select materials compatible with microwave exposure, thermal cycling, and chemical conditions
Design pressure-rated and temperature-rated systems as required
Develop sealing, containment, and shielding solutions
Ensure uniform flow distribution to complement homogeneous microwave heating, potentially including mechanical agitator design
Create detailed CAD models and fabrication drawings
Work with contract manufacturers and machine shops
Lead system assembly, installation, and commissioning
Implement safety systems and industrial design best practices
As the Ideal Candidate, You Would Bring:
MS, or PhD in Mechanical Engineering or related field
5+ years experience in industrial equipment, reactor design, or process systems
Experience designing fluid handling systems (slurries preferred)
Strong CAD proficiency (SolidWorks or similar)
Experience with material selection for thermal and chemical environments
Familiarity with industrial fabrication methods
Hands-on build and troubleshooting experience
What We Offer:
Annual salary of $110,000 with potential for expanded responsibilities and corresponding compensation growth as the company advances through the seed stage.
Company equity.
Healthcare and dental insurance.
Competitive PTO.
Unfortunately at this time, we are unable to sponsor visas.
We are focused on building a diverse and inclusive workforce. If you’re excited about this role, but do not meet 100% of the qualifications listed above, we encourage you to apply.
Start Date: July 7, 2026
