Advanced Cell Engineer Cell DiagnosticsComponents

Job Description

On-site: This role is categorized as onsite. This means the successful candidate is expected to report to Wallace Battery Cell Innovation Center (WBCIC) in Warren Michigan on a full-time basis (5 days/week).

The Role:
At General Motors were driving the future of mobility through cutting-edge battery innovation. As an Advanced Cell Engineer youll play a critical role in developing and refining cell technologies that power our next-generation electric vehicles. This is a hands-on on-site position at WBCIC where youll collaborate with top-tier engineers and researchers to push the boundaries of energy storage.

Were looking for a candidate who is passionate about advancing technologies in automotive battery cells and eager to continuously learn and grow. You will be responsible for leveraging your technical experience to complement a talented team of advanced cell engineers to develop and implement solutions for cell designs and builds that meet project timelines.

What Youll Do (Responsibilities):

• Lead development and optimization of cell designs (e.g. electrode loading/balance electrolyte systems cell geometry) to meet performance durability safety DC fast charge and cost targets.
• Define and validate DC fast charge use cases limits and cell-level requirements; design test protocols to evaluate DCFC performance heat generation and degradation.
• Translate learnings into design rules and operating envelopes that can be applied across programs and manufacturing environments.
• Plan and execute advanced diagnostic work to understand performance gaps and degradation mechanisms (e.g. rate/temperature studies DC fast charge cycling aging protocols impedance/OCV analysis tear-downs post-mortem characterization).
• Design and execute experiments using three-electrode (3E) or reference-electrode configurations to isolate anode and cathode behavior track lithium inventory shifts and identify limiting electrodes under aggressive conditions (e.g. DCFC low temperature high SOC storage).
• Use physico-chemical and electrochemical techniques (e.g. half-cell analysis materials characterization) to identify limiting mechanisms and propose corrective actions at material electrode or cell level.
• Analyze complex multi-factor data sets (design process test) to extract key drivers and quantify trade-offs using appropriate statistical and modeling tools.
• Act as technical owner for assigned cell designs material sets or technology workstreams ensuring robust requirements validation plans and documentation.
• Provide day-to-day technical guidance and mentoring to junior engineers co-ops and technicians.
• Collaborate cross-functionally with R&D cell design pack/vehicle engineering quality purchasing and supplier partners to solve issues and deliver program milestones.
• Contribute to and help maintain internal specifications standards and best practices for cell design performance testing DC fast charge evaluation and diagnostic methods.
• Champion a strong safety culture in lab and pilot environments ensuring compliance with GM safety policies and regulatory requirements.
• Identify and drive continuous improvement opportunities in test methods workflows instrumentation utilization and data quality.

Your Skills & Abilities (Required Qualifications):

• Bachelor of Science in Engineering Material Science Chemistry or other related Science Degree
• 5 years of relevant experience
• Advanced understanding of cell technology including cell design and manufacturing processes
• Strong understanding of structurepropertyprocess relationships in electrodes (porosity tortuosity particle morphology binder systems calendaring etc.).
• Strong problem-solving skills and ability to break down ambiguous technical problems into executable workstreams.
• Excellent written and verbal communication skills including experience presenting technical content to mixed technical and non-technical audiences.
• Demonstrated ability to work effectively in cross-functional fast-paced environments and to lead without formal authority.
• High level analytical ability where problems are unusual and complex

What Can Give You a Competitive Edge (Preferred Qualifications):

• Masters Degree PhD or other advanced certifications
• Hands-on experience with advanced diagnostic techniques (e.g. EIS GITT cyclic voltammetry XRD SEM/EDS XPS tomography gas analysis).
• Direct experience with pouch cell design build and testing for automotive applications.
• Experience with high-nickel cathodes silicon- or SiOx-containing anodes or next-generation electrolyte systems.
• A passion for innovation and a collaborative mindset in a fast-paced environment
