About the position

Solid Power is seeking a Multiphysics Modeling Scientist to join their talented team working to revolutionize the battery industry through the development of next-generation, all solid-state rechargeable batteries. Solid Power is a dynamic, fast-paced, collaborative, and innovative team environment. The preferred candidate will have significant experience working with and using multiphysics simulations to model chemical systems, heat transfer dynamics, and electrochemical devices. The candidate will be expected to guide synthetic approaches for dry, inorganic powders by modeling conditions in high-throughput powder reactors. They will also work to update existing thermal abuse models that integrate atomic-scale reaction kinetics with continuum-scale heat transfer dynamics. The candidate should be comfortable building P2D/P4D DFN models and using these approaches to guide experimental planning, especially as it relates to battery formulation improvements.

Responsibilities

  • Develop continuum-scale reactor models for dry inorganic powder synthesis, coupling heat transfer, gas flow, mass transport, and reaction kinetics to guide reactor conditions and experimental planning.
  • Upgrade existing COMSOL-based implementations for thermal abuse modeling of ASSB cells.
  • Develop and validate mathematical models (both fundamental physics-based and data driven) to predict thermal, mechanical, and electrochemical behavior of ASSB materials, sub-assemblies, and finished cells.
  • Work with subject matter experts to develop experimental plans to isolate and quantify key model parameters, while producing minimal solvers that can be used by scientists/engineers.
  • Collaborate with subject matter experts to refine and continually validate modeling approaches, while employing best-practice workflows (i.e., mesh sensitivity analysis, ablation testing, unit testing, parameter sensitivity quantification).
  • Clearly explain to internal stakeholders the uncertainty in modeling predictions and write documentation on proposed upgrades that could be used to improve certainty.
  • Collaborate with data scientists on strategies to accelerate multiphysics modeling solvers and on strategies to guide virtual experiment prioritization (e.g. Bayesian approaches).
  • Collaborate with atomic-scale and coarse-grained modeling team members to translate their outputs into continuum-scale model inputs, assumptions, parameters, and validation targets.

Requirements

  • Master’s or Ph.D. in Computational Chemistry, Materials Engineering, Chemical Engineering or a related Electrochemical discipline.
  • 2+ years of professional experience using commercial software to develop multiphysics models of lithium-ion batteries.
  • A deep understanding of electrochemistry, preferably with at least some experience in battery systems.
  • Proficiency with Python and common data science libraries such as Pandas, NumPy, and SciPy.
  • Strong analytical and statistical problem-solving skills, having specific experience with configuring solvers for regression and parametrization tasks.
  • Experience working with COMSOL is necessary.
  • The ability to formulate coupled multiphysics models from first principles, including governing equations, assumptions, constitutive relationships, source terms, and boundary/initial conditions, prior to software implementation is a must.
  • Rapid learner and a self-motivated individual who takes ownership in a collaborative start-up environment.
  • Excellent communication, negotiation, and organizational skills with strong attention to detail.

Nice-to-haves

  • Experience working in Ansys, work with PyBaMM, and general python knowledge are all a strong plus.
  • Previous experience building 1D PDE/ODE models from first principles and manually implementing them is a strong plus (e.g., Numpy implementation for Gummel iteration, Newton iteration, segregated solver).
  • Familiarity with agentic code development concepts and the limitations of LLMs is a plus.
  • The candidate should be someone who stays up to date on the latest continuum-scale modeling approaches.

Benefits

  • medical/dental/vision insurance
  • employer paid Life/AD&D/STD/LTD insurance
  • 401k with company match
  • 8 paid holidays + the week between Christmas and New Years off
  • Unlimited PTO
  • up to six (6) weeks paid FMLA leave
  • cell phone reimbursement
  • eligibility to participate in our bonus and equity plans

Common Interview Questions And Answers

1. HOW DO YOU PLAN YOUR DAY?

This is what this question poses: When do you focus and start working seriously? What are the hours you work optimally? Are you a night owl? A morning bird? Remote teams can be made up of people working on different shifts and around the world, so you won't necessarily be stuck in the 9-5 schedule if it's not for you...

2. HOW DO YOU USE THE DIFFERENT COMMUNICATION TOOLS IN DIFFERENT SITUATIONS?

When you're working on a remote team, there's no way to chat in the hallway between meetings or catch up on the latest project during an office carpool. Therefore, virtual communication will be absolutely essential to get your work done...

3. WHAT IS "WORKING REMOTE" REALLY FOR YOU?

Many people want to work remotely because of the flexibility it allows. You can work anywhere and at any time of the day...

4. WHAT DO YOU NEED IN YOUR PHYSICAL WORKSPACE TO SUCCEED IN YOUR WORK?

With this question, companies are looking to see what equipment they may need to provide you with and to verify how aware you are of what remote working could mean for you physically and logistically...

5. HOW DO YOU PROCESS INFORMATION?

Several years ago, I was working in a team to plan a big event. My supervisor made us all work as a team before the big day. One of our activities has been to find out how each of us processes information...

6. HOW DO YOU MANAGE THE CALENDAR AND THE PROGRAM? WHICH APPLICATIONS / SYSTEM DO YOU USE?

Or you may receive even more specific questions, such as: What's on your calendar? Do you plan blocks of time to do certain types of work? Do you have an open calendar that everyone can see?...

7. HOW DO YOU ORGANIZE FILES, LINKS, AND TABS ON YOUR COMPUTER?

Just like your schedule, how you track files and other information is very important. After all, everything is digital!...

8. HOW TO PRIORITIZE WORK?

The day I watched Marie Forleo's film separating the important from the urgent, my life changed. Not all remote jobs start fast, but most of them are...

9. HOW DO YOU PREPARE FOR A MEETING AND PREPARE A MEETING? WHAT DO YOU SEE HAPPENING DURING THE MEETING?

Just as communication is essential when working remotely, so is organization. Because you won't have those opportunities in the elevator or a casual conversation in the lunchroom, you should take advantage of the little time you have in a video or phone conference...

10. HOW DO YOU USE TECHNOLOGY ON A DAILY BASIS, IN YOUR WORK AND FOR YOUR PLEASURE?

This is a great question because it shows your comfort level with technology, which is very important for a remote worker because you will be working with technology over time...
