Description
About Blue Current
Blue Current (the “Company”) is the industry leader in the development of silicon solid state batteries. Free of flammable liquid electrolytes, Blue Current’s fully dry, inherently safe batteries significantly reduce risks to human and environmental health while providing a higher-performance alternative to traditional lithium-ion batteries. Blue Current’s silicon-based platform is highly adaptable, enabling a cost-effective solution for both the mobility and stationary storage markets. Blue Current’s team works out of its state-of-the-art headquarters and pilot line facility in Hayward, California. To learn more about Blue Current, Inc., visit http://bluecurrent.com. Position Summary
The Senior Cell Assembly Engineer is responsible for developing and refining the cell assembly processes at the core of Blue Current's solid-state battery technology, where the novelty of the cell design and formulation means that innovation is a routine part of the job rather than an exception. This engineer owns the assembly process from receipt of dry electrode rolls through finished cell delivery, defining the tooling requirements that mechanical and equipment engineers build to, and applying a sophisticated quality toolkit (visual inspection, layer alignment and tolerancing, X-ray imaging, and electrochemical characterization) to ensure that every cell meets defined structural and performance standards. Working across electrode process, cell engineering, mechanical engineering, and quality teams, the Senior Cell Assembly Engineer is a central integration point where materials, processes, and measurements come together. Success means a cell assembly process that produces high-quality, well-characterized cells consistently today, with the process understanding in place to support scale-up.
Essential Functions & Responsibilities
Develops and refines cell assembly processes for solid-state batteries, including electrode handling and punching, alignment, lamination, stacking multiple layers, sealing pouches and tabs, and delivering finished products to the cell test team
Defines tooling and fixture requirements for cell assembly operations, working closely with mechanical and equipment engineers to specify, validate, and iterate on tooling that meets process needs
Characterizes assembly process parameters and their relationship to cell structural and electrochemical outcomes, building the process understanding needed to set specifications and improve yield
Applies advanced metrology techniques including X-ray imaging, electrochemical characterization, and electrochemical testing to evaluate assembly quality and diagnose process failures
Develops and monitors assembly-stage QA/QC protocols in partnership with the Quality team, including visual inspection criteria, edge alignment and layer tolerancing standards, and acceptance criteria for finished cells
Leads root cause investigations on assembly defects and cell failures attributable to assembly process, implementing and documenting corrective actions
Collaborates with electrode process and cell engineering teams to ensure assembly process decisions account for upstream material and electrode constraints and downstream cell performance requirements
Contributes to scale-up planning by identifying critical assembly process parameters and tooling requirements that must be addressed on the path to high-volume manufacturing
Leads projects by developing clear, actionable plans with defined milestones and success metrics, managing timelines effectively, and ensuring high-quality, on-schedule execution.
Supports a strong safety culture by following and improving laboratory safety practices, demonstrating exemplary experimental techniques, and helping implement best-practice updates.
