Battery Failure Analysis & Quality Engineer

Pittsburgh Tomorrow; Pennsylvania; On-site; USD 90,000 - 130,000; Full time

Job summary

Eos Energy Enterprises is seeking a Materials and Failure Analysis Engineer to lead the incoming materials quality program and drive root-cause investigations into battery failures. You will translate field returns and production issues into corrective actions, working with supply chain, R&D, and manufacturing to safeguard product performance and safety.

The role sits at the intersection of materials, electrochemistry, mechanical/electrical engineering, and quality, requiring strong analytical

Qualifications

• Bachelor's degree in materials science, electrical engineering, mechanical engineering, chemical engineering, or a related field
• 5+ years of experience in failure analysis, reliability engineering, or quality engineering, ideally in batteries, electronics, or electromechanical systems
• Hands-on experience with failure analysis techniques such as electrical/electrochemical testing, microscopy (SEM/optical), thermal analysis, or X-ray/CT imaging

Responsibilities

• Lead root-cause failure analysis (RCFA) on battery modules and systems, from initial triage through corrective action
• Design and execute teardown, inspection, and testing protocols for failed units returned from the field or flagged during production
• Apply analytical techniques (electrical characterization, electrochemical testing, microscopy, spectroscopy, thermal imaging, etc.) to identify failure modes and mechanisms
• Partner with R&D, suppliers, and manufacturing engineering to close the loop between failure findings and design or process improvements
• Develop and maintain FMEA (Failure Mode and Effects Analysis) documentation for cell, module, and system components
• Track failure trends across production and fielded fleets; build dashboards and reports to communicate findings to engineering and leadership
• Support supplier quality investigations for component-level failures
• Own incoming parts quality and inspection processes, including incoming material inspection plans, sampling strategies, and acceptance criteria for raw materials and purchased components
• Investigate incoming inspection rejects and non-conformances, working with suppliers and sourcing teams to drive corrective and preventive actions (CAPA)
• Contribute to safety investigations, ensuring findings are documented to meet internal and regulatory requirements
• Author clear, well-documented failure analysis reports and present findings to cross-functional stakeholders
• Help build out failure analysis lab capabilities, tooling, and standard operating procedures as the team scales
