Position Summary

We're looking for a Sr Cell Engineer to lead the technical work of moving Blue Current's cell technology from early-stage R&D through scaled production. You'll stay engaged across the full cell development arc, from working alongside scientists on novel cell designs and materials, to partnering with manufacturing and process engineers to make those designs buildable at scale. An ideal candidate brings genuine expertise, creativity, open-ended problem solving capability, and the ability to work cross-functionally in mid-size-and-growing organizations. In this role, you'll operate independently on complex technical problems, own your area of work end-to-end, and will be responsible for project design and execution within your domain.

Essential Functions & Responsibilities

- Designs and executes hypothesis-driven experiments to understand and improve cell performance, using a mix of analytical techniques (chemical/material metrology like SEM, spectroscopy, etc) and statistical techniques (design of experiments, regression, and capability analysis)
- Leads root cause analysis on cell underperformance and unexpected failures, developing mechanistic explanations rather than correlations, and driving the design or process changes that eliminate the cause.
- Investigates material and interface failure modes (e.g. degradation, delamination, contact loss, mechanical fracture, contamination), and quantifies their contribution to performance loss and yield loss
- Directs cell characterization and post-mortem analysis in partnership with metrology, selecting the techniques that discriminate between competing failure hypotheses rather than merely describing the result
- Leads new cell design introduction from small-format research samples through pilot and production-representative builds. Successful engineers identify scale-sensitive failure modes early, and work with the manufacturing team and R&D to iterate and solve problems
- Defines cell design requirements that balance electrochemical performance, mechanical robustness, and process capability, and develops cell designs and processes as the cell is scaled out of the lab to ensure high quality product rollout
- Collaborates with research scientists on new cell chemistries, electrolyte systems, electrode architectures. Collaborates with process engineers to ensure scalability.
- Documents experimental findings, cell specifications, and design-of-record revisions so that conclusions and the evidence behind them remain traceable across research, engineering, and manufacturing
- Mentors junior engineers and technicians in experimental design, failure analysis, and characterization practice. Represents cell engineering in cross-functional technical planning and project execution
- Models and improves laboratory safety practices, demonstrating sound experimental technique and helping implement best-practice updates
- Other duties as assigned, consistent with the scope and level of this position

## Minimum Qualifications

Education

- PhD in relevant field, or MS (with 3+ years of relevant experience), or BS (with 5+ years of relevant experience); relevant fields include Materials Science, Chemical Engineering, Chemistry, Physics, or a related field, with a focus on batteries or electrochemical devices

## Experience

- Demonstrated experience taking a cell design from laboratory scale through at least one meaningful scale-up stage, such as a format change, process transfer, or production pilot
- Hands-on experience with cell build unit operations (including 3 or more of: coating, calendering, slitting, stacking or winding, electrolyte or separator integration, sealing, and formation) and an understanding of how variation in each affects performance and yield
- Experience designing and interpreting cell characterization studies, including rate testing, electrochemical impedance spectroscopy, and cycle life testing
- Experience conducting failure analysis and connecting observed failure modes to upstream process or design root causes

## Skills & Knowledge

- Technical foundation in electrochemical cell design, including electrode architecture, stack design, electrolyte-electrode compatibility, and the trade-offs between performance and manufacturability
- Statistical fluency sufficient to design experiments that support defensible conclusions, and to analyze cell test results (A/B, run charts, DOE analysis, and related)
- Clear technical writing sufficient to author and maintain cell specifications, SOPs and build documentation that other functions rely on
- Ability to communicate across research, process engineering, quality, and operations, and to make decisions with incomplete information while stating assumptions explicitly

Certifications / Licenses

- N/A

## Preferred Qualifications

- Experience with dry room or glovebox build environments and the constraints they place on cell design and material handling
- Experience defining cell architecture (format, stack design, current collector configuration, sealing approach) in a scaleup environment
- Experience contributing to equipment and capability roadmap planning, including identifying gaps between current infrastructure and scaleup requirements
- Background in structured problem-solving methods such as design failure mode and effects analysis or experience in root cause analysis with cell teardowns and deep material analytics
