The Battery Systems Engineer is responsible for defining, developing, and integrating Li-Ion and/or ultra-capacitor battery systems that meet OEM and regulatory requirements for low-voltage (12V-48V) automotive applications. This role involves requirements engineering, system integration, functional safety, and collaboration with cross-functional teams to deliver safe, reliable, and high-performance energy storage solutions. This position is ideal for candidates with a strong background in battery technology, automotive systems engineering, and compliance with industry standards (ASPICE, ISO 26262, ISO 15288, INCOSE SE Handbook).

  • Capture, analyze, and refine system-level requirements from OEMs, product management, and internal teams.
  • Allocate performance and other limiting requirements to all functional levels.
  • Ensure traceability between system requirements, architecture, and validation plans using a requirements management tool.
  • Balance competing requirements across multiple customers and regulatory frameworks.
  • Define system architectures, including cell selection, thermal, electrical, and mechanical interfaces.
  • Develop detailed block diagrams, interface definitions, and system-level schematics.
  • Allocate functional and non-functional requirements to subsystems and components.
  • Manage trade-offs between safety, performance, cost, and scalability.
  • Implement according to the Clarios Functional Safety Process (consistent with ISO 26262) throughout the development lifecycle.
  • Conduct safety analyses such as HARA, FTA, FMEA, and Common-Mode Analysis.
  • Own the system level DFMEA and coordinate the connections with other sub-systems and component FMEAs.
  • Define safety goals, technical safety concepts, and validation strategies.
  • Define and manage thermal, electrical, and mechanical interfaces between the battery pack, BMS, and vehicle powertrain.
  • Work closely with software, mechanical, and electrical teams to optimize system-level interactions.
  • Support Hardware-in-the-Loop (HiL) and Model-in-the-Loop (MiL) testing to validate system integration.
  • Lead the development of Design Verification Plans (DVPs), ensuring comprehensive validation coverage for system performance, durability, and compliance with OEM and regulatory standards.
  • Document verification coverage of all requirements with traceability in the requirements management tool.
  • Participate in system-level validation, durability testing, and failure mode analysis.
  • Assist in aging studies, thermal modeling, and electrical load analysis for predictive performance assessments.
  • Ensure system and component designs are optimized for manufacturing, assembly, and scalability.
  • Work closely with manufacturing, quality, and supply chain teams to refine designs for production feasibility.
  • Support Advanced Product Quality Planning (APQP), contributing to control plan development and DFMEA execution.
  • Release the battery system design to production, ensuring alignment with assembly plant and supplier requirements.
  • Own system-level DFMEA, ensuring proper alignment with subsystem and component-level DFMEAs.
  • Ensure alignment with ASPICE 3.1, ISO 15288, and INCOSE Systems Engineering best practices.
  • Act as a technical liaison between systems, mechanical, electrical, thermal, and software engineering teams.
  • Manage engineering documentation to ensure a sensible archive of information including engineering calculations, engineering drawings, intellectual property, DFMEAs, validation reports, meeting minutes, trip reports, and customer documents/communication.
  • Provide technical guidance to designers, engineers, and suppliers.
  • BS/MS in Electrical, Mechanical, Systems Engineering, or related field (or equivalent experience).
  • 5+ years of experience in automotive battery systems, powertrain, or electrification projects.
  • Experience with ISO 26262 Functional Safety, ASPICE, and INCOSE Systems Engineering methodologies.
  • Proficiency in requirements management tools (Jama, DOORS), simulation tools (MATLAB, Simulink), and validation frameworks.
  • OEM/Tier 1 experience in automotive battery systems is preferred.
  • Medical, dental and vision care coverage and a 401(k) savings plan with company matching – all starting on date of hire.
  • Tuition reimbursement, perks, and discounts.
  • Parental and caregiver leave programs.
  • All the usual benefits such as paid time off, flexible spending, short-and long-term disability, basic life insurance, business travel insurance, Employee Assistance Program, and domestic partner benefits.
  • Global market strength and worldwide market share leadership.
  • HQ location earns LEED certification for sustainability plus a full-service cafeteria and workout facility.
  • Clarios has been recognized as one of 2024's Most Ethical Companies by Ethisphere.
