Responsibilities
Act as the primary triage point for advanced EV system issues across E/E architecture, HV propulsion, software/firmware, and safety domains within CE1
Verify reproducibility of symptoms; assess field vs. lab data for safety implications; clearly bound the scope to prevent harm
Gather and align data: logs (CAN, Ethernet, serial), diagnostic trouble codes, BMS history, thermal trends, charging data, OTA history, and variant information
Design controlled reproduction steps or data-window analyses, document assumptions and limitations
Propose non-invasive checks first; specify required data, traces, bench tests, and sequence tests by likelihood and risk
Use structured methods (fault trees, 5 Whys, 8D) to connect symptoms to root causes; identify latent failure modes and environmental factors
Lead and coordinate with hardware, software, powertrain, thermal, safety, and cybersecurity teams; drive concise briefs, handoffs, and decision records
Produce concise triage briefs, RCA summaries, and knowledge-base entries; maintain a pattern library of recurring symptom clusters and typical causes
Apply a formal risk scoring approach (likelihood x impact) to determine escalation paths to appropriate domains and management levels
Propose immediate mitigations (config/workarounds) and longer-term actions (design changes, software patches, OTA updates)
Archive evidence, record decisions, and deliver a handoff brief with next steps and owners; ensure downstream teams have clear action items
Qualification
Required
Bachelor's degree in Electrical/Automotive Engineering, Computer Science, or related field; 3+ years of hands-on EV/system diagnostics (or equivalent)
Strong command of vehicle E/E architectures, domain controllers, HV propulsion (battery, BMS, inverter, motor, thermal management), and functional safety basics
Proficiency with automotive networks (LIN, CAN/CAN-FD, Ethernet), diagnostic tools, log analysis, and interpretation of system interactions, timing, and environmental impacts
Demonstrated ability to perform structured root-cause analysis (fault trees, 5 Whys, Ishikawa) and derive actionable steps from partial data
Experience with OTA/update processes, software versioning, traceability, and baseline/fault-change management
Strong written and verbal communication; able to produce executive summaries and technical appendices; proven cross-functional collaboration
Comfortable in a fast-paced program environment; able to balance speed with rigor and prioritize high-impact work
Preferred
Advanced diagnostic tooling and environments
Experience with HIL, bench/rig testing, lab equipment, and diagnostic simulators
Coding and data tools
Proficiency in Python or MATLAB for data processing; data visualization skills (Excel, Tableau, Power BI, etc.)
RCA documentation
Experience with formal RCA templates, pattern libraries, and reusable triage playbooks
Additional EV domains
Familiarity with charging standards (NACCS/CCS), V2X concepts, and battery chemistries
Functional safety training/certifications (ISO 26262 or equivalent)
Foundational knowledge of ISO 26262/ASIL concepts and basic automotive cybersecurity practices relevant to vehicle systems
Automotive cybersecurity basics
OEM or supplier-specific EV safety training
Strong understanding of vehicle dynamics
An eagerness to work cross-functionally in a dynamic environment where you are part of a high performing team
