About the job
About Us
Molten Industries advances how people live, build, and move through innovative materials, chemicals, and fuels. We are commercializing breakthrough technology to make high-quality, CO2-neutral graphite and hydrogen using only methane and electricity as inputs. Transportation (cars, trucks, ships, planes) and heavy industry (cement, steel, chemicals, fertilizer) currently make up over 40% of global CO2 emissions. Graphite is up to 25% of the mass of lithium-ion batteries used in phones, laptops, and electric vehicles. Battery-grade graphite and clean hydrogen can enable carbon-neutral or carbon-negative transport, shipping, fertilizer, steel, cement, and chemicals.
Molten started in 2021 out of a garage at Stanford and is backed by top-tier venture capital firms and a world-class advisory board. We believe in using our talents for the most meaningful work of our lives - mitigating the effects of climate change. We want to do the kind of work that you can write home about. The work that you’ll tell your grandkids about. Engineering feats, growth miracles, and rock-solid, real-world change. At Molten we believe in dreaming big, working with urgency, and getting our hands dirty.
Join us in our effort to push the final frontier of decarbonization.
The Role
As a member of Molten’s early team, you will lead the design and build out of reactors and mechanical systems to produce clean hydrogen using our proprietary technology. You will help design, engineer, specify, procure, build, and test new ideas and setups as we scale from our pilot system to industrial plants. You will wear a variety of hats and are excited by work that spans mechanical, electrical, and chemical engineering. You are a scrappy self-starter with a bias to action. You enjoy being hands-on and building physical systems, and you are comfortable translating complex problems into achievable goals.
What you will do
- Use 3D tools to design, build, and test our breakthrough hydrogen production technology
- Hack, build, and troubleshoot physical prototypes for quick feedback loops and testing
- Independently create engineering models and drawings for parts that you will source from suppliers
- Perform engineering calculations to validate equipment and tool designs
- Work closely with a small technical founding team to push our hydrogen production technology from bench-top to industrial scale
What you will bring
- We are looking for candidates with 2+ years of experience
- BS / MS in Mechanical Engineering (or equivalent)
- Expert in 2D/3D CAD modeling (e.g. SolidWorks)
- Skilled in creating detailed engineering drawings, with strong knowledge of geometric dimensioning and tolerancing
- Strong technical fundamentals in fluid mechanics, thermodynamics, and structural analysis
- Working knowledge of machine shop fabrication processes and machine building
- Experience working directly with suppliers to procure parts with blazing fast lead times
- Hands-on experience is essential
- Excellent written and verbal communication skills
You do not need to have every listed skill to be a great fit! If you are passionate about this opportunity and think you have the skills to help our team succeed, please apply!
Bonus Points
- Startup experience or experience in a fast-paced environment
- Experience with electrical drawings and designs
- Experience designing for 24/7 industrial use, with safety and reliability at the forefront
- Experience designing, engineering, and building chemical reactors or other chemical plant or semiconductor production equipment
- Experience with coding and design of control systems and electronics
- Knowledge of pyrolysis, reforming, gasification or other thermal conversion processes
- Experience with solids, fluid handling, solid gas separation, and associated equipment
- Experience with compressors and pumps
- Experience with hydrogen or graphite production processes
- Experience with finite element analysis modeling
