Senior Electrical Systems Engineer, Batteries

About the role

Your ImpactBatteries are a critical subsystem in all modern mobile devices and require careful attention to safety, performance, reliability, and regulatory compliance. As the Senior Systems Engineer for Batteries within the Devices Hardware Engineering team, you will serve as the subject matter expert for battery technologies across Axon’s product portfolio.

Responsibilities

• Develop cross-functional system requirements for battery sub-assemblies across body-worn, automotive, and fixed outdoor product lines
• Define cell and pack requirements (capacity, voltage, cycle life, temperature range, discharge rate) for each program
• Own the battery integration checklist for each new product
• Evaluate new battery chemistries and technologies from safety and performance perspectives
• Monitor industry trends — new chemistries, form factors, energy density improvements — and translate into actionable roadmap input
• Develop and maintain Axon's battery technology roadmap and integration plan for future solutions across all device platforms
• Lead technical RFP process in collaboration with cross-functional teams for supplier selection
• Provide technical input into RFQs for battery cell and pack suppliers
• Lead supplier qualification — review datasheets, test reports, and qualification data; push back when specs don't hold
• Manage supplier relationships from qualification through production
• Partner with suppliers to qualify and deliver subassemblies meeting safety, performance, quality, and regulatory requirements
• Lead detailed design reviews of supplier and internal BMS schematics and PCB layouts; review for protection coverage, design margins, fault handling, and safe operating area compliance
• Review battery integration into product for compatibility with cell operating limits
• Write and execute battery characterization and verification test plans for NPI programs (capacity, cycle life, abuse, temperature)
• Lead Ongoing Reliability Testing (ORT) for secondary batteries across multiple suppliers
• Interpret test data, make go/no-go calls at program gates, and own battery-related failure analysis
• Ensure compliance with UN 38.3, IEC 62133, UL 2054, and applicable market/regulatory requirements
• Track regulatory changes impacting the portfolio and flag early
• Present regularly on battery technology trends and NPI program status to cross-functional stakeholders
• Monitor, report, and maintain a dashboard covering Axon's full fleet of batteries across all active programs

Requirements

• BS or MS in Electrical Engineering, Systems Engineering, Chemical Engineering, or a closely related field
• 6–9 years of battery systems, power systems, or related interdisciplinary engineering experience
• Industry experience with high-performance, battery-powered, size- and weight-constrained products such as body cameras, action cameras, wearables, or mobile communications devices
• Hands-on experience with battery pack development from concept through high-volume manufacturing — including cell selection, pack design review, and supplier qualification
• Experience leading Ongoing Reliability Testing (ORT) programs for secondary batteries across multiple suppliers
• Experience with NPI program cycles (EVT, DVT, PVT) and the associated battery characterization and verification activities at each gate
• Solid understanding of battery chemistry types (Li-ion, LiPo, LiFePO4, primary lithium) and their tradeoffs in safety, energy density, cycle life, and temperature performance
• Solid understanding of battery pack architecture — cell configuration, BMS design, protection circuits, fuel gauging, and thermal management
• Familiarity with emerging battery technologies and ability to assess maturity and suitability for product integration
• Proven ability to lead technical RFP and RFQ processes for battery cell and pack suppliers
• Proven ability to independently lead scoped engineering analysis and drive tradeoffs across EE, ME, firmware, product management, and test teams
• Experience managing supplier relationships through qualification and into production, including audit and corrective action processes
• Demonstrated experience achieving regulatory certification for worldwide product deployment: UN 38.3, IEC 62133-2, UL 1642, UL 2054
• Working knowledge of additional standards relevant to battery fleet management and enterprise products: IEC 62619, UL 1973
• Familiarity with transportation and shipping requirements for lithium batteries (IATA, DOT 49 CFR)
• Proven experience developing systems engineering documentation: system architectures, block diagrams, interface diagrams, SRDs, and requirements traceability matrices
• Ability to build and maintain battery fleet dashboards and present program status and technology assessments to cross-functional and executive audiences
• Solid skills with documentation, analysis, and presentation tools: Word, Excel, PowerPoint; familiarity with PLM/requirements tools (e.g., Arena, Jira, Windchill, or equivalent) is a plus
