Systems Engineer - Commercial Vehicle

Requisition Summary

This role serves as the primary liaison between Vehicle Function Definition (VFD), Software Development, suppliers, and PACCAR Technical Center (PTC) Verification & Validation (V&V) teams to ensure software and system content is truly ready for system‑level verification and vehicle testing.

The #1 objective is Verification Readiness: ensuring that before PTC begins HIL/SIL and vehicle testing, the software architecture and functional requirements are complete and high quality, supplier systems are feature‑complete, supplier testing is executed per approved test plans, and known defects have been addressed or have an agreed corrective action plan and timing.

This role serves under the Vehicle Function Definition group and improves program execution by establishing clear readiness gates, aligning documentation and deliverables, and ensuring test planning is complete, accurate, and actionable across the complete development product lifecycle.

• Define and manage verification readiness criteria and deliverables required for PTC V&V to begin system HIL/SIL and vehicle testing (requirements completeness/quality, architecture readiness, supplier feature completeness, supplier test completion, defect status).
• Ensure software/system architecture and interfaces are defined with sufficient quality and maturity to support integration and downstream validation.
• Drive requirements quality: ensure Function Requirements / Function Design documents are complete, testable, consistent, peer‑reviewed, and traceable to verification methods.
• Ensure suppliers have executed component/subsystem testing per their test plans, and that defects are either corrected or have an approved corrective action plan prior to PTC test execution.
• Join stakeholder review sessions for FRS and FDS documents, offering input on how testable the functional requirements are.

• Create and maintain preliminary and formal test plans that validate software‑enabled vehicle features, ensuring complete requirements coverage and clear test intent.
• Partner with PTC V&V to translate requirements and architecture into executable validation strategy across component test, SIL/HIL, and vehicle test domains.
• Track verification readiness progress, risks, and gaps; proactively escalate blockers with proposed options and timelines.

• Collaborate as needed with the Defect Review Board (DRB) and cross‑functional stakeholders to triage defects, improve problem statements, and ensure timely assignment to the appropriate SMEs.
• Focus on driving corrective actions (not duplicating PTC's root‑cause function): ensure ownership, containment plan (as needed), corrective action plan, and verification closure approach are defined and tracked to completion.

• Define and document program validation activities and plans to ensure products meet reliability and verification confidence targets.
• Identify and incorporate test activities into Product Financial Supporting Documentation (PFSD) for accurate budget forecasting, including ensuring program funding is identified and secured for planned validation work.
• Ensure validation results are documented in required systems (e.g., DVPR/WRR) and failures are documented/closed appropriately in FRACAS when applicable.

• Improve and standardize verification readiness processes, engineering workflow, deliverables, and timelines aligned to best practices, V‑model development, and industry standards.
• Mentor and develop junior engineers by modeling strong documentation discipline, requirements quality practices, and structured problem‑solving methods.
• Identify process improvement opportunities and propose solutions that improve quality, efficiency, and cross‑site alignment.
• Travel up to 20% depending on program phase, including on‑site support at PTC, PACCAR sites.

• Bachelor of Science degree in Systems Engineering, Mechanical Engineering, Software…
