Plant Vehicle Engineer, Propulsion, HV Systems & Chassis At Slate, we're building safe, reliable vehicles that people can afford, personalize and love—and doing it here in the USA as part of our commitment to reindustrialization. The spirit of DIY and customization runs throughout every element of a Slate, because people should have control over how their trucks look, feel, and represent them. Slate is looking for a hands-on Plant Vehicle Engineer, Propulsion, HV Systems & Chassis to support vehicle assembly, launch readiness, production quality, and continuous improvement for propulsion, high-voltage, thermal, and chassis systems in the Warsaw Assembly Plant. This role supports plant execution of propulsion and chassis content across drive unit(s), HV battery, HV system integration, thermal systems, suspension, steering, brake systems, and related vehicle interfaces, ensuring each system can be assembled consistently and to product intent in a manufacturing plant environment. This role serves as the engineering link between the manufacturing plant, Design & Release Engineering, Manufacturing Engineering, Quality, Suppliers, Production, Safety, End of Line, Vehicle Integration, Service, and other cross-functional teams. The position focuses less on new component design or manufacturing process ownership and more on protecting product intent in the plant, resolving production and integration issues, and improving build quality in production. This role does not own production release of propulsion, HV, thermal, or chassis designs. It is responsible for identifying build and integration issues, supporting root cause analysis, protecting safety-critical and quality requirements, and driving plant-side issue resolution in partnership with Design & Release Engineering and the broader manufacturing organization. Propulsion, HV & Chassis Integration Support Support the launch and ongoing production of propulsion, high-voltage, thermal, and chassis systems in a vehicle assembly plant environment. Serve as the Plant Vehicle Engineering point of contact for production and vehicle integration issues related to drive unit(s), HV battery interfaces, HV cables/connectors, HV system integration, thermal systems, suspension, steering, brake systems, and chassis interfaces. Help ensure plant build execution maintains product design intent, safety requirements, quality standards, functional performance, serviceability, and customer expectations. Enforce safety-critical characteristics, HV safety boundaries, and torque-to-spec requirements; maintain traceability and escalation protocols; support containment and no-build/no-ship decisions where required. Production Issue Resolution Investigate, diagnose, and resolve production issues related to drive unit installation, HV battery and electrical interfaces, HVIL concerns, cable routing, thermal connections, chassis assembly, brake system installation, torque-controlled joints, leaks, fit/function, NVH, diagnostics, and component interfaces. Lead root cause analysis, containment, corrective action development, and breakpoint coordination; validate permanent fixes before closure. Analyze production data, audit findings, end-of-line results, repair trends, teardown feedback, supplier concerns, and plant feedback to identify risks, trends, and improvement opportunities. Launch, Change & Cross-Functional Support Partner with Design & Release Engineering, Propulsion Engineering, HV Systems Engineering, Chassis Engineering, Manufacturing Engineering, Quality, Production, Suppliers, Safety, End of Line, Vehicle Integration, and Service teams to resolve plant and vehicle-level concerns. Support engineering change implementation, prototype/pilot builds, breakpoint coordination, plant readiness, issue tracking, containment, readiness reporting, and lessons learned. Contribute plant-perspective input to DFM/DFA reviews, PFMEAs, control plan reviews, and station readiness reviews; represent build and integration requirements in product and process improvement discussions. Documentation & Process Improvement Review and support production documentation, including work instructions, inspection standards, torque requirements, quality alerts, repair procedures, HV safety instructions, and related process documentation. Support issue tracking, change management, quality systems, deviation / waiver processes, containment documentation, and production breakpoint control. Drive continuous improvement actions that reduce defects, improve first-time quality, minimize rework, and strengthen production robustness for propulsion, HV, thermal, and chassis systems. Success Factors Improve first-time quality for propulsion, HV battery, HV system integration, thermal systems, and chassis including brake systems. Reduce rework, repair loops, and recurring production issues across drive unit(s), HV interfaces, thermal systems, suspension, steering, brake systems, and chassis-related content. Improve launch readiness through effective build support, issue tracking, station readiness, system integration discipline, and closure management. Improve containment effectiveness and accelerate issue resolution through clear triage, documentation, breakpoints, traceability, and validation. Strengthen feedback loops between the plant, Design & Release Engineering, Manufacturing Engineering, Quality, Production, Suppliers, Safety, End of Line, Vehicle Integration, and Service.
