Responsibilities
Own and manage the CAD models and large, multi-level assemblies for Alpha engine hardware, maintaining assembly structure, mates, and configuration integrity as the design matures
Create, release, and review detailed manufacturing drawings with appropriate GD&T that properly communicates design intent per ASME Y14.5
Analyze tolerance stackups across assemblies
Establish and enforce CAD best practices, modeling standards, templates, and assembly structures that keep large assemblies robust, performant, and maintainable
Manage configuration, revision, and change control of models, drawings, and bills of materials within the PLM system, including release workflows
Collaborate with manufacturing, quality, and suppliers to ensure drawings are manufacturable and inspectable, and support disposition of non-conformances
Support design reviews with up-to-date model and drawing deliverables
Lead development of design concepts that reduce part count, complexity, cost, and lead time while preserving design intent and maximizing reliability
Provide hands-on CAD and GD&T support to the broader Alpha Engines team
Qualifications
Required
B.S. in Mechanical, Aerospace, or a related engineering discipline, or equivalent design and drafting experience
1-3 years of experience in mechanical design of hardware
Expert proficiency with 3D CAD, including the modeling and management of large, complex assemblies (Siemens NX strongly preferred)
Strong command of GD&T, tolerancing, and ASME Y14.5, and the ability to produce complete, manufacturable, and inspectable engineering drawings
Experience with PLM and configuration management tools (Teamcenter preferred), including formal revision and change control
Experience performing tolerance stackups and fit, clearance, and interference analysis across assemblies
Working knowledge of manufacturing and inspection methods (precision machining, castings/forgings, additive manufacturing, welding, sheet metal, assembly, and NDT) and design for manufacturability
Deep knowledge of engineering fundamentals and a demonstrated history of applying first principles to arrive at simple, robust solutions
Excellent problem-solving, communication, and technical writing skills
Proven ability to rapidly develop solutions with partially defined or evolving requirements
Desired Qualifications
Advanced degree in Mechanical Engineering, Aerospace Engineering, or an equivalent field
5+ years creating flight hardware CAD and drawings for launch vehicle, spacecraft, or liquid rocket engine propulsion systems
Experience administering or customizing NX and Teamcenter (templates, standards, item types, and release workflows)
Familiarity with Python, NX Open, or other scripting to automate CAD and drawing tasks
Experience with model-based definition (MBD) and GD&T-driven inspection, including CMM and first-article inspection
In-depth knowledge of cryogenic, high-pressure, or high-temperature hardware and compatible material selection
Proven experience reducing the complexity of large integrated assemblies to reduce part count, cost, and lead time
Demonstrated experience supporting the full hardware lifecycle, from blank-sheet design through application
