Job Description

Li-Ion Battery Design Engineer

As a Li-Ion Battery Design Engineer, you will play a critical role in designing, developing, qualifying, and sustaining rechargeable lithium-ion battery systems. In this role, you will contribute to end-to-end battery pack development, including cell selection, battery architecture, Battery Management System (BMS) integration, safety and regulatory compliance, verification and qualification testing, supplier collaboration, and lifecycle management.

You will apply strong engineering fundamentals, battery technology expertise, risk management principles, and product development processes to deliver safe, reliable, compliant, and cost-effective battery solutions. You will work closely with cross-functional engineering teams and global battery suppliers throughout the product lifecycle.

Your role:

• Design and develop Li-Ion battery packs from concept through production release, including in-house and supplier-led development.
• Define battery architecture, including cell configuration, electrical protection, thermal management, mechanical packaging, and BMS requirements.
• Evaluate and select Li-Ion cells based on performance, capacity, lifecycle, safety, availability, cost, and regulatory requirements.
• Define and support BMS functions such as State of Charge (SOC), State of Health (SOH), cell balancing, temperature monitoring, fault detection, and protection algorithms.
• Develop battery requirements, design specifications, verification plans, qualification plans, and technical documentation.
• Perform battery performance evaluation covering capacity, runtime, charge/discharge behavior, thermal performance, aging, shelf life and cycle life.
• Ensure battery design compliance with applicable standards and regulations such as IEC 62133-2, UL 2054, UL 1642, UN 38.3, IEC 60601-1, EU Battery Regulation, Battery Waste Management Rules, IATA requirements, RoHS, and REACH.
• Perform design and safety risk management activities, including hazard analysis, FMEA, fault tree analysis, and risk assessments.
• Lead battery failure investigations, root cause analysis, troubleshooting, and implementation of corrective actions.
• Collaborate with cell manufacturers, BMS suppliers, battery pack manufacturers, contract manufacturers, and cross-functional engineering teams.
• Support supplier technical reviews, design reviews, manufacturing transfer, qualification, and production readiness activities.
• Manage component obsolescence, alternate component qualification, ECRs/DCRs, and sustaining engineering activities throughout the product lifecycle.
• Support electronic hardware development, including MCU, power, sensing, connectivity, protection circuits, schematic design, component selection, PCB development, verification, debugging, and integration.
• Contribute to continuous improvement of product safety, reliability, quality, performance, and cost.

You are a fit if:

• Bachelor's or master's degree in electrical engineering, Electronics Engineering, Mechanical Engineering, Energy Storage Engineering, or equivalent.
• Minimum 7+ years of hands-on experience in Li-Ion battery pack design and development, battery electronics, or hardware engineering.
• Strong knowledge of lithium-ion cell technologies, battery pack architecture, BMS, protection circuits, battery safety, and charging/discharging fundamentals.
• Good to have - Experience in medical device battery development and IEC 60601-1 environments will be preferred.
• Strong analytical, problem-solving, technical documentation, and troubleshooting skills.
• Ability to work independently while effectively coordinating with cross-functional and global teams.
• Good written and verbal communication skills.

Minimum required Education:

• Bachelor's or master's Degree in Electrical Engineering, Electronic Engineering, Mechanical Engineering, Energy Storage Engineering or equivalent.

Minimum required Experience:

• Minimum 7+ years of hands-on experience in Li-Ion battery pack design and development, battery electronics, or hardware engineering. Experience working with global battery suppliers and contract manufacturers.
