Requirements

5+ years of work experience in Battery and/or Automotive industries.
At least a bachelor’s degree in an engineering discipline.
Strong understanding of High Voltage Safety and international battery regulations.
Holistic understanding of thermal and electrical interdependence in battery pack design.
Proficiency with automated requirements management tools (e.g., JAMA, Doors, Polarion) and issue tracking tools like JIRA.
Strong communication, multitasking, and interpersonal skills, both in presentation and technical writing.
Ability to work within dynamic development timelines and accelerated hardware production cadences.

Nice To Haves

Experience launching a high voltage battery pack is preferred.
Experience launching a BEV in the EU and international markets is a strong nice to have.

Responsibilities

Lead the pack level systems design process to analyze vehicle, powertrain, and end-user specifications to derive pack system requirements.
Lead the process of translating international regulations, including EU 2023/1542 (Battery Passport), EC No 1907/2006 (REACH), and ECE R100, into actionable battery pack and sub-system requirements.
Ensure the battery's conformity with relevant requirements by generating technical documentation and performing risk assessments as required.
Lead the decomposition of legislative requirements and the creation of associated test cases.
Establish Requirements Verification Traceability (RVT) to ensure every legislative mandate is linked to a verified test result.
Coordinate with test and validation teams for scheduling, lead test kickoff reviews, and perform final report signoff.
Act as the single point of ownership for requirements used for outsourced battery pack programs.
Define the Statement of Requirements (SoR) for RFQs, responding to supplier feedback, managing requirements, creating and linking test cases, and tracking validation status through program milestones.
Own the maintenance and decomposition of thermal system requirements into component-level requirements.
Manage the thermal subsystem DFMEA and support Component DREs in their DFMEA elicitation.
Coordinate closely with System Modeling teams to ensure thermal requirements align with 1D/3D modeling outputs.
Cascade sub-system requirements, validation procedures, and verification traceability.
Ensure all technical documentation is maintained and accessible as defined by Rivian’s data management policies.
Chair DFMEA working sessions and maintain the DFMEA as the development program matures.
Work alongside Battery Control Systems, Cell/Module, and Mechanical Structures Engineers to ensure robust traceability.
