Job Summary:
The Senior Mechanical Engineer is responsible for designing and integrating custom industrial machines from concept through deployment. This hands-on role supports the development of next-generation powder-metal 3D printers built on a CNC platform, requiring deep experience with motion systems, electromechanical assemblies, and machine-level integration. The ideal candidate has built machinesnot just modeled componentsand is fluent in sourcing, assembly, and system-level mechanical design.

Essential Functions:
● Redesign and upgrade existing 3D printing systems, replacing prototype components with production-grade machined parts to support long-term scalability and manufacturing readiness.
● Specify, select, and integrate motion control systems including stepper motors, extended motion axes, recoating mechanisms, spindles, and linear guides.
● Modify and expand build chamber designs, including sealing and controlled access systems to enable inert gas environments.
● Incorporate cosmetic design elements as provided by external industrial design partners.
● Develop and implement new mechanical processes, technical solutions, and machine features to support ongoing hardware development initiatives.
● Collaborate closely with electrical, software, and controls engineers to ensure complete system integration.
● Lead prototype builds, mechanical testing, debugging, and iterative design improvements.
● Support design transfer to manufacturing and provide production support for deployed systems.
● Maintain complete design documentation including BOMs, mechanical drawings, and revision histories.

Required Qualifications:
● Proficiency with SolidWorks or similar CAD software, including assemblies, tolerancing, and CNC-ready design
● Strong understanding of motion components, linear guides, actuation, and mechanical fasteners
● Proven ability to build and integrate electromechanical systems in a lab or production environment
● Hands-on experience sourcing components
● Effective collaboration with cross-functional teams in a fast-paced RD setting

Preferred Qualifications:
● Experience designing sealed systems, gas enclosures, or powder-handling equipment
● Field installation, debug, or customer training experience

Education and Experience:
● Bachelors degree in Mechanical Engineering or a related field required
● Minimum of 6 years of experience in mechanical design, machine development, or automation
● Masters degree preferred but not required

Physical Requirements and Work Environment:
● Regularly works in an engineering lab and machine build environment
● Must be able to sit, stand, and perform hands-on work at machines and workbenches
● Occasionally required to lift and move up to 50 pounds
