Twelve is a new kind of chemical company built for the climate era. Our breakthrough technology eliminates emissions by turning CO2 into essential products. We are a team of scientists, engineers and problem solvers on a mission to fundamentally shift the way the world addresses climate change and lead the transition to a fossil free future with our carbon transformation technology.

The Fabrication Team is a dynamic part of Twelve’s technical team responsible for formulating inks, designing electrodes, coating substrates and scaling-up the core component of our CO2 electrolyzer system, the Membrane Electrode Assembly (MEA). The MEA is made of catalysts, polymer electrolytes, and other substrates that catalyze the conversion of CO2 to CO and other chemicals. Our team works collaboratively to translate research ideas into functioning systems and products with high performance and durability. So if you're ready to roll up your sleeves with a diverse, world class team of material scientists, electrochemists and engineers in an innovative and supportive environment to make a positive, measurable impact on climate, Twelve is the place for you. 

Job Brief

We are looking for a Formulation Engineer to conduct research and develop inks for coating substrates and fabricating the anodes and cathode components of our CO2 electrolyzers.  In this position you will be engaged with multiple cross-functional teams to explore various aspects of developing scalable coating processes by rapidly iterating through ink formulations, optimizing ink mixing methods, modifying the deposition of thin films on substrates, and tuning formulation and fabrication parameters (solids ratio, viscosity, surface tension, drying rate etc.) to optimize electrode composition and morphology. You will be tasked with becoming the subject matter expert on ink rheology, develop new solvent-based ink dispersion techniques, evaluate the stability of materials and optimizing new ink formulations for various fabrication/deposition methods.  You will also be collaborating with a team of scientists, engineers and technicians to conduct R&D hands-on primarily on-site in Berkeley, CA.

What you will do

  • Formulate inks for spray deposition, slot die or roll-to-roll coating and support various fabrication projects to scale up Twelve’s MEA production 
  • Plan and execute projects or design experiments to optimize coating methods and drying behavior of inks to fabricate high performance electrodes
  • Lead and mentor a team of engineers and technicians and provide technical support to projects leads
  • Liaise and communicate effectively between the R&D project teams and fabrication team to achieve project goals and meet deliverables
  • Analyze and present experimental findings to colleagues and collaborators
  • Direct, train, and mentor MEA fabrication technicians and engineers on new processes and tools
  • Rapidly analyze measurement data for process and characterization parameters
  • Maintain and manage good record keeping and communication platforms

Who you are

  • You have a relevant STEM Master's Degree and 6+ years of experience, or a Bachelor's degree in a STEM field with 10+ years of relevant experience
  • Hands on experience working with, or developing, inks for roll to roll or other relevant coating methods or equipment
  • Prior experience leading projects fabricating electrodes using slot die, roll-to-roll coating, Meyer rod coating, blade coating, or gravure coating methods is strongly preferred
  • Experience working with and operating ink preparation and ink mixing equipment
  • Familiarity with electrochemical systems (fuel cells, electrolyzers) is desired

Twelve Benefits

  • Medical, dental, and vision coverage
  • Paid sick days and vacation
  • Competitive salary and equity compensation commensurate with experience
  • Diverse and inclusive work environment


We believe that the unique contributions of each individual is the driver of our success. To make sure that our products and culture continue to incorporate everyone's perspectives and experience we never discriminate on the basis of race, religion, national origin, gender identity or expression, sexual orientation, age, or marital, veteran, or disability status.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past. For more information about this form or the equal employment obligations of federal contractors under Section 503 of the Rehabilitation Act, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at
