Senior Staff Engineer, Rheology

Are you ready to build America’s energy future? Form Energy is an American manufacturing and energy technology company. We’re revolutionizing energy storage with cost-effective, multi-day technology designed to keep the electric grid secure and reliable, even during extended periods of stress. By strengthening the electric system and reimagining what’s possible, we’re giving clean energy a whole new form!

In recent years, Form Energy has earned a number of accolades, including being named by TIME as a "Best Invention", MIT Technology Review as a "Top Climate Tech Company To Watch", and Fast Company as "One of the Next Big Things In Tech". We are making rapid progress on our mission of delivering energy storage for a better world, and our team is growing just as rapidly to meet demand.

We have signed contracts with leading electric utilities across the United States and production of our iron‑air batteries is underway at our first high‑volume manufacturing facility in West Virginia.

Working for Form Energy is more than just a job, it’s a chance to be part of something extraordinary. And now - right as we significantly scale up battery manufacturing - might be the most exciting moment in the company’s history to join. We are assembling a team of highly talented and driven individuals across the country. Driven by our core values of humanity, excellence, and creativity, our team is determined to deliver on our mission and transform the energy landscape for the better.

Feeling energized to make a meaningful impact on the world? Then keep reading - you’ve come to the right place.

Form Energy is hiring a scientist to drive the slurry and dispersion development behind next‑generation electrodes for our iron‑air technology. This role reports into the manager of Discharge Cell R&D. As part of our R&D team, you will work on developing aqueous slurry formulations, characterizing key rheological properties, and identifying process‑property relationships in partnership with chemists, materials scientists, and battery engineers.

This is an exciting opportunity to help shape and be part of the growth of a fast‑moving company with breakthrough technology and an incredible mission!

Relocation assistance is available.

• Define the approach, characterization strategy, and success criteria for new formulation problems where no established method exists, reducing ambiguity and complexity for the broader team

• Design, formulate, and optimize aqueous slurries containing active materials and conductive carbon additives, balancing rheological behavior with downstream processability and electrode performance

• Establish quantitative links between mixing and processing conditions and the resulting particle microstructure, dispersion state, and transport properties of the finished electrode in a battery

• Diagnose and resolve dispersion stability challenges in chemically active or corrosive continuous phases, drawing on first‑principles understanding of solvent‑mediated and particle‑to‑particle interactions

• Build and operate a comprehensive slurry characterization toolkit

• Translate raw data into predictive models of stability and performance

• Serve as the subject matter expert in colloidal and dispersion science for the R&D organization and represent the function in cross‑functional and program‑level design reviews

• Bachelor's + 10 years work experience;
  Master’s degree + 8 years work experience;
  PhD with 4+ years work experience with degree in Physics, Chemical Engineering, or related fields

• Deep knowledge of colloidal and interfacial science, including solvent‑mediated and particle‑to‑particle interactions

• Demonstrated experience in developing slurries, dispersions, or particle‑laden formulations for demanding applications, such as battery electrodes (flow or semi‑solid), fuel cell catalyst inks, ceramic or coating slurries, or comparable multiphase systems

• Proficiency in developing and using characterization techniques (e.g. rheometry, vertical scan light‑scattering, analytical centrifugation) to establish process‑property and structure‑property relationships that predict electrode and…
