Full Job Description
About the Role
We are seeking a motivated Manufacturing Engineer to drive process development
of a novel battery technology. In this role, you will design, execute, and analyze experiments to deepen our understanding of process-design-material interactions and work with a cross-functional team to realize process improvements.

The ideal candidate is hands-on, has a first-principles approach, and thrives in a fast-paced
environment where you will directly contribute to the factory ramp.

What You'll Do
  • Process Development & Scaling: Invent, characterize, and optimize battery
    manufacturing processes (e.g., electrode coating, calendering, assembly, cell assembly,
    formation, or testing).
  • Hands-on Experimentation: Perform proof-of-concept tests to green-light new materials, methods, and equipment. Build prototypes and run pilot line experiments.
  • Data Analysis: Use data analysis tools (Python, SQL, JMP, Minitab, or Tableau) to
    analyze process capabilities, establish SPC (Statistical Process Control) limits, and
    improve yield.
  • Root Cause Analysis: Diagnose issues found during cell manufacturing, driving root
    cause identification and corrective action using structured methods (DMAIC, 5 Whys,
    8D).
  • Equipment Commissioning: Assist in the installation, FAT (Factory Acceptance Test),
    and SAT (Site Acceptance Test) of new automated manufacturing equipment.
  • Documentation: Create and maintain Manufacturing Instructions (MI), PFMEAs, and
    Control Plans to define process standards for production teams.


Who you are
  • B.S. or M.S. in Mechanical Engineering, Chemical Engineering, Material Science, or a
    related field.
  • 1-3 years of hands-on experience in an R&D lab or manufacturing facility (prior
    experience in batteries or semiconductors is a major plus).
  • Proficiency in experiment design, statistical data analysis (JMP, Python, Matlab), and
    data visualization/representation.
  • Knowledge of CAD software (SolidWorks, Catia) .
  • Exceptional problem-solving skills and a desire to work in a high-expectation, fast-paced
    environment.
  • Ability to communicate clearly and work cross-functionally with quality, production, and
    design teams.
This role is right for you if
  • You are a fast learner and adjust quickly to new learnings and opportunities.
  • You are both comfortable working in ambiguity and capable of maintaining focus on important details.
  • You are looking for a role in a fast-growing startup.

Onsite Expectations
Given the nature of the work and team this role is is expected to be onsite 5 days a week.

Expected Compensation

Base Salary Range: $135,000 - $185,000

Base salary is determined based on many factors such as: market rate, candidate experience, interview performance, and geographic location.
