About the role

Key responsibilities & impact

Create, maintain, and improve high-quality 3D CAD models and assemblies in NX for ECU housings, brackets, seals, mounting features, connector interfaces, and vehicle integration content.
Develop and release 2D drawings with appropriate GD&T, critical-to-function callouts, and tolerance considerations to support robust and manufacturable components.
Perform advanced CAD ownership activities including package studies, fit and clearance reviews, interference checks, section analyses, and swept-volume evaluations to identify issues early and drive practical design solutions.
Support the mechanical design of electronics packaging, housings, and enclosures from concept through production release in collaboration with senior and staff engineers.
Design mechanical components such as castings, injection moldings, stampings, gaskets, PCBA mounts, and structural or vehicle interface features under program timing constraints.
Own day-to-day Teamcenter responsibilities for assigned content, including structure management, BOM authoring, revision control, release readiness, and engineering change execution.
Manage CAD and product definition updates resulting from design reviews, build learnings, supplier feedback, and program changes while maintaining strong data integrity and traceability.
Coordinate cross-functional interface definition with vehicle structures, packaging, electrical, PCB, and supplier teams to ensure mechanical content is compatible with adjacent systems and vehicle constraints.
Drive definition and coordination of error-proofing, bracket/interface features, and related mechanical integration details needed to support assembly robustness and vehicle implementation.
Participate in DFM, DFA, and DFx reviews with suppliers and manufacturing partners, incorporating feedback into CAD and drawings to improve manufacturability, quality, cost, and release maturity.
Present CAD, drawing updates, packaging status, and key mechanical risks in design reviews and cross-functional stakeholder meetings.
Follow and help improve CCH mechanical design standards, templates, and best practices for NX modeling, drawing quality, Teamcenter usage, and release execution.
Provide periodic onsite support for prototype builds, engineering verification activities, fit checks, and issue resolution when hands-on presence is needed to close key development risks.

Requirements

What you’ll need

Bachelor of Science in Mechanical Engineering or related discipline.
6–10+ years of mechanical design experience in complex assemblies such as automotive products, electronics, or similar systems.
At least 3+ years of hands-on experience with Siemens NX and Teamcenter in a production development environment.
Demonstrated expertise in NX including: Parametric 3D part and assembly modeling, Drawing creation and detailing to ASME standards, Use of expressions, reusable features, and modeling best practices for robust designs, Packaging studies, interference analysis, and design problem solving in complex assemblies.
Demonstrated proficiency in Teamcenter including: Managing large assemblies and configurations, Structure management and BOM authoring, Release and change management, including ECRs, ECNs, and revision control.
Solid understanding of mechanical fundamentals including solid mechanics, materials, tolerance analysis, GD&T, and basic heat transfer.
Experience collaborating across disciplines and locations, with strong written and verbal communication skills.
Proven ability to manage multiple CAD, data, and release tasks in parallel while prioritizing effectively and delivering to program timing.
Ability to work effectively in a remote-first environment while maintaining close collaboration with onsite and cross-functional teams.
Willingness to travel periodically for prototype builds, design reviews, testing support, and other critical onsite program activities.
