Mechanical CAD & PLM Engineer

About Thea Energy:   Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.   Position Overview: The Lead Mechanical CAD & PLM Engineer owns the configuration and integrity of Thea Energy's products by directly managing the top-level assembly in Siemens NX and creating, maintaining, and enforcing the modeling standards, drafting standards, review workflows, and release process for the company. The role pairs end-to-end ownership of one or more top-level assemblies with process and procedure governance over CAD and PDM standards and processes. These responsibilities will be executed using Siemens NX and Siemens Teamcenter to achieve project goals through a lean, high-performance process adhering to ISO 9001 standards. 

The Lead Mechanical CAD & PLM Engineer is the single point of accountability for how Thea structures, controls, and evolves its top-level CAD configurations, and for ensuring that the PDM environment remains stable, current, and well-governed as the team scales. The role combines deep CAD authority with system-administrator responsibility, and partners closely with subassembly leads, systems engineering, and engineering leadership. 

Key Responsibility Areas:

Top-Level Assembly Configuration Ownership 

• Assembly Ownership: Serve as the named owner of a designated top-level assembly (TLA), responsible for its structure, release state, and configuration integrity from concept through production. 

• Subassembly Coordination: Partner with subassembly leads to maintain alignment between subordinate models and the TLA, including merge cadence, naming conventions, structural standards, interfaces, space claim, and modeling best practices. 

• Conflict Resolution: Drive resolution of configuration conflicts between subassemblies and ensure design intent preservation across the assembly hierarchy. 

Cross-Functional Interface Coordination 

• Interface Tracking: Partner with the Systems Engineer to track and document mechanical-to-electrical, mechanical-to-fluid, and mechanical-to-software interfaces relevant to the assigned TLA. 

• Interface Register: Maintain a PDM-based interface register based on an authoritative source that reflects the current physical and logical boundaries between subsystems.
