Jobs at East Penn Manufacturing

Leads mechanical design and analysis for lithium-ion battery modules and packs from concept through production. Responsibilities include CAD, structural and thermal FEA, tolerance analysis, prototype builds, validation testing, root-cause investigations, supplier support, engineering changes, and design-for-manufacturing. The role collaborates cross-functionally to improve performance, cost, quality, reliability, safety, and manufacturability while mentoring junior engineers.

Develop and support battery management system software from requirements and architecture through integration, verification, and production release. Build protection, diagnostics, communications, monitoring, balancing, contactor control, and state-estimation functions. Troubleshoot complex software, hardware, electronics, and battery-system issues; define verification methods; perform hands-on testing; collaborate across engineering and manufacturing teams; and provide technical oversight to external engineering partners.

Leads complex lithium-ion battery module and pack development from concept through production. Defines requirements, architecture, interfaces, validation strategies, and technical specifications; leads integration, testing, design reviews, root-cause investigations, engineering changes, supplier resolution, and risk mitigation. Provides technical leadership across mechanical, electrical, thermal, manufacturing, quality, test, and program teams while mentoring junior engineers and driving robust, manufacturable products.

Leads multiple complex lithium battery product development projects from production readiness through end of life. Manages schedules, budgets, deliverables, risks, phase-gate reviews, financial performance, executive reporting, and cross-functional alignment. Supports PMO best-practice development, advises portfolio and department leaders, and may manage and develop direct reports. Ensures projects meet scope, cost, quality, timing, safety, and performance objectives.

Supports the design, validation, testing, documentation, and manufacturing of lithium-ion battery modules and components. Responsibilities include analyzing test data, conducting failure analysis, supporting prototype builds and pilot production, resolving manufacturing issues, participating in DFMEA and PFMEA activities, and contributing to root cause and corrective action initiatives. The intern collaborates with engineering, quality, and manufacturing teams in an on-site battery production environment.

Supports engineering project planning, execution, documentation, financial performance, production planning, risk management, and issue resolution. Coordinates project tasks and commitments, maintains stakeholder communication, assists with proposals, tracks milestones and KPIs, and helps improve operational processes. The role also supports the project manager, follows safety procedures, and works in a temperature-controlled manufacturing environment with occasional weekend or holiday work.

Supports materials and supply chain teams with inventory management, cycle counting, forecasting, scheduling, procurement, variance investigations, data analysis, and process improvement. The intern collaborates cross-functionally in a manufacturing environment, assists with purchasing and inventory accuracy, presents recommendations, and gains exposure to end-to-end supply chain operations.

Lead the design, development, release, and validation of customized battery packs for industrial and low-voltage automotive applications. Translate customer requirements into system specifications, lead safety analyses, support certification compliance, develop verification and validation plans, and coordinate with engineering, sales, customers, OEM partners, testing, and simulation teams. Own product design, safety, quality documentation, project risk reporting, and process improvement while working with minimal supervision.

Provides technical leadership and architectural ownership for multi-generation battery management systems used in military, commercial, and industrial applications. Responsibilities include embedded firmware and electronics architecture, BMS algorithms, safety and compliance, requirements traceability, risk assessments, verification strategies, diagnostics, testing, manufacturability, and system sustainment. The role serves as the subject-matter expert across firmware, hardware, controls, sensing, and system integration.

Lead process improvement and engineering projects for lithium-ion battery manufacturing. Analyze KPIs, OEE, yield, cycle time, reliability, and defects using statistical tools and data analysis. Drive Lean, Six Sigma, Kaizen, root-cause analysis, corrective actions, process documentation, supplier evaluation, and integration of new manufacturing technologies. Collaborate cross-functionally with production, quality, safety, R&D, supply chain, and design engineering while promoting safe, efficient manufacturing operations.
