Senior Mechanical Engineer

Mattur; Phoenix (AZ); On-site; USD 90,000 - 140,000; Full time

Job summary

Mattur is seeking a Senior Mechanical Engineer to own mechanical designs from concept through production release. You will develop production-quality 3D models and GD&T documentation, collaborate with machining, fabrication, and assembly teams, and guide prototypes to manufacturing readiness.

The role requires hands-on prototyping, problem-solving in a shop environment, and experience with common manufacturing processes to improve designs and ensure successful production transfer.

Qualifications

• Bachelor's degree in Mechanical Engineering or closely related field.
• 5–8 years of mechanical engineering experience in hardware product development.
• Experience taking designs from prototype to production release.
• Strong proficiency in SolidWorks and production drawings with GD&T.

Responsibilities

• Own mechanical design from concept through production release using SolidWorks.
• Create and maintain production-quality 3D models, drawings, BOMs, and GD&T documentation.
• Plan and support prototyping, build, testing, and iteration with shop teams.
• Collaborate with manufacturing, suppliers, and contract manufacturers to resolve design-for-manufacturing issues.
• Support systems integration and cross-functional collaboration across engineering, manufacturing, and operations.

Job description

Mattur is seeking a Senior Mechanical Engineer to support the design, development, and refinement of mechanical components and subsystems across early-stage and production hardware. This role is for an engineer who can take ownership of meaningful hardware workstreams - from concept and CAD through prototyping, testing, and release to manufacturing - while working closely with fabrication, machining, and assembly teams.

We are looking for someone with strong hands‑on instincts, sound design judgment, and practical experience working through manufacturing considerations as designs mature from prototype to production.

Key Responsibilities

Mechanical Design and Documentation

• Own the design and development of mechanical components and subassemblies from requirements through production release using SolidWorks and related engineering tools.
• Produce and maintain production-quality 3D models, 2D drawings, bills of materials, and related design documentation, including clear GD&T and functional tolerancing.
• Apply sound design-for-manufacturing and design-for-assembly principles across machined parts, sheet metal, weldments, additive parts, fixtures, and related assemblies.
• Support tolerance stack-up analysis and fit-up planning for critical interfaces and assemblies.
• Support drawing release and engineering change processes including revision control, ECOs/ECNs, and as-built updates.

Prototyping, Build, and Test

• Plan and support prototype builds with internal and external resources, including process selection, material choices, and build sequencing.
• Work hands‑on in the shop and lab assembling, troubleshooting, and improving hardware alongside machinists, fabricators, and technicians.
• Support test activities for mechanical subsystems, including fit/function, durability, vibration, thermal, and structural validation, and translate results into practical design improvements.
• Design basic jigs, fixtures, and tooling to support prototyping and low-rate builds.

Manufacturing and Supplier Collaboration

• Partner closely with manufacturing and operations to help prepare designs for pilot and production builds.
• Work with suppliers and external manufacturing partners as needed on design feedback, manufacturability questions, and part refinement.
• Identify manufacturing issues during prototype and early production phases and help drive practical solutions around tolerances, inspection, finishing, and assembly.
• Help improve documentation quality and part readiness ahead of fabrication and assembly.

Cross-Functional Collaboration

• Partner with electrical, controls, and manufacturing teams to support system-level integration, packaging, mounting, routing, and interface definition.
• Communicate design intent clearly through drawings, models, written documentation, and working sessions.
• Manage multiple parallel workstreams and help drive assigned deliverables to completion in a fast-paced development environment.

Qualifications

• Bachelor's degree in Mechanical Engineering or a closely related field.
• 5 - 8 years of relevant mechanical engineering experience in hardware product development, including experience supporting designs from prototype through production release.
• Strong proficiency in SolidWorks or similar 3D CAD software.
• Strong experience producing manufacturing-ready drawings with GD&T and related documentation for machinists, fabricators, and suppliers.
• Meaningful hands‑on experience with hardware prototyping, assembly, troubleshooting, and design iteration in a shop or lab environment.
• Practical manufacturing experience across common processes such as CNC machining, sheet metal, weldments, additive manufacturing, fixtures, and mechanical assembly.
• Experience working directly with machinists, fabricators, suppliers, or contract manufacturers is strongly preferred.
• Experience using simulation and engineering analysis tools such as FEA to support design decisions, along with judgment around when to simulate versus when to test.
• Strong communication skills and the ability to work effectively across engineering, manufacturing, and operations.
