5d•$135,000 - $150,000

About The Position

We’re seeking a Mechatronics Engineer to drive the design, development, and optimization of high-pressure solids feed and removal systems—critical systems enabling reliable biomass delivery and ash management in our novel high-pressure gasification platform for carbon-negative power cycles. In this role, you’ll own end-to-end development of robust, high-reliability solids handling hardware in a fast-paced, collaborative startup environment. From conceptual design and mechatronic integration through prototyping, testing, rapid iteration, and validation, you’ll deliver solutions that ensure continuous, clog-free operation under extreme pressure and temperature conditions. You’ll collaborate closely with gasification, test, and controls engineers, providing technical expertise on critical decisions to accelerate progress while maximizing system uptime, flexibility, and overall carbon impact.

Requirements

Bachelor’s degree in Mechanical, Mechatronics, Aerospace Engineering, or related field
3+ years of hands-on experience designing, building, and testing solids handling, feeding, or conveyance systems (preferably under high pressure/temperature)
Strong expertise in mechanical design, actuation, sensing, controls integration, and materials selection for abrasive/corrosive environments
Proficiency with 3D CAD (SolidWorks/NX preferred), FEA, and GD&T; experience generating fabrication drawings and BOMs
Proven ability to own technical development of complex hardware from concept through validation in fast-paced settings
Demonstrated track record of delivering reliable mechatronic systems with minimal downtime
Curious, inventive, and entrepreneurial mindset—thrives in ambiguity and drives practical solutions forward

Nice To Haves

Advanced degree (M.S. or Ph.D.) in Mechanical or Mechatronics Engineering
Experience with high-pressure systems in rocket propulsion, gasifiers, pneumatic conveying, lock hopper systems, or similar
Hands-on experience integrating PLCs, sensors, and control loops for automation
Proficiency in programming/scripting for data analysis, automation, or control (Python, MATLAB, Ladder Logic, etc.)
Background in startup or agile hardware development environments

Responsibilities

Own the design, analysis, and integration of high-pressure solids feed (e.g., lock hoppers, screw feeders) and removal (e.g., ash extraction, filtration) systems
Develop mechatronic solutions combining mechanical design, actuation, sensing, and control logic for reliable solids transport in harsh environments
Perform sizing calculations, 3D modeling, structural/FEA analysis, and flow modeling for solids handling components and assemblies
Plan, execute, and analyze solids flow tests and integrated high-pressure test campaigns, driving rapid learning and iteration
Lead hardware development cycles—from detailed design and procurement through manufacturing, assembly, commissioning, and performance upgrades
Leverage additive manufacturing, modern actuators/sensors, and automation tools to accelerate innovation and improve system robustness
Propose and implement continuous improvements to eliminate bottlenecks, enhance safety, and increase operational reliability
