• Understanding of common manufacturing processes: sheet metal forming, machining, welding, trimming, drilling, fastening, fixturing, and assembly.
• Strong communication skills with the ability to mentor engineers and establish engineering standards across a multidisciplinary team.

Responsibilities

• Own the mechanical design process from concept through released production drawings, assemblies, and documentation.
• Create and modify mechanical designs for structural defense products, including missile, hypersonic, UAV, and aerospace metallic structures.
• Identify producibility issues related to forming, welding, machining, trimming, fixturing, assembly, inspection, and integration.
• Serve as the engineering release authority for CAD models, drawings, assemblies, and design data.
• Administer and maintain the Product Data Management (PDM) system, including workflows, revision control, permissions, and configuration management.
• Develop high-quality CAD models, detailed drawings, assemblies, and bills of materials.
• Establish and maintain engineering drawing standards, GD&T practices, Design for Manufacturability (DFM) guidelines, and engineering best practices.
• Review and approve engineering work produced by other team members to ensure quality, consistency, and compliance with established standards.
• Mentor manufacturing, process, and applications engineers on mechanical design principles, engineering documentation, and product development best practices.
• Collaborate closely with manufacturing teams to improve producibility, reduce cost, shorten lead times, and increase manufacturing efficiency.
• Identify manufacturing risks early and drive design improvements that enhance quality and scalability.
• Participate in customer technical discussions, design reviews, manufacturability reviews, and cross-functional engineering meetings.
• Support continuous improvement initiatives across engineering documentation, configuration management, and product development workflows.

Job description

About Machina Labs:

Engineering moves at software speed. Manufacturingdoesn't. Yet.

Machina Labs is changing that. We build intelligent, software-defined factories that produce complex metal structures directly from digital design. By integrating advanced metal forming, robotics, and automated production inside a flexible factory architecture, we enable customers to move from prototype to production in weeks, not years.

Backed by Lockheed Martin, Toyota, and NVIDIA,we'rebuilding the manufacturing infrastructurethat defense, aerospace, and advanced mobility programs will run on.

If you want to work on hard problems that matter and see them fly, drive, and defend, this is the place.

Job Description:

Machina Labs is seeking a Senior Mechanical Engineer – Aerospace & Defense to serve as a technical leader within our engineering organization. This is a hands-on role that combines mechanical design, engineering ownership, and technical mentorship. You will be responsible for driving designs from concept through release while establishing the engineering standards, configuration management processes, and design practices that support a rapidly growing manufacturing organization.

As a key member of the engineering team, you will own the release of engineering documentation, oversee our Product Data Management (PDM) system, mentor engineers across manufacturing and process engineering, and ensure that designs are optimized for production, quality, and scalability.

This position is ideal for an experienced engineer who enjoys balancing technical execution with engineering leadership and is passionate about developing robust design processes in a collaborative startup environment.

Key Responsibilities:

• Own the mechanical design process from concept through released production drawings, assemblies, and documentation.
• Create and modify mechanical designs for structural defense products, including missile, hypersonic, UAV, and aerospace metallic structures.
• Identifyproducibility issues related to forming, welding, machining, trimming, fixturing, assembly, inspection, and integration.
• Serve as the engineering release authority for CAD models, drawings, assemblies, and design data.
• Administer and maintain the Product Data Management (PDM) system, including workflows, revision control, permissions, and configuration management.
• Develop high-quality CAD models, detailed drawings, assemblies, and bills of materials.
• Establish and maintain engineering drawing standards, GD&T practices, Design for Manufacturability (DFM) guidelines, and engineering best practices.
• Review and approve engineering work produced by other team members to ensure quality, consistency, and compliance with established standards.
• Mentor manufacturing, process, and applications engineers on mechanical design principles, engineering documentation, and product development best practices.
• Collaborate closely with manufacturing teams to improve producibility, reduce cost, shorten lead times, and increase manufacturing efficiency.
• Identify manufacturing risks early and drive design improvements that enhance quality and scalability.
• Participate in customer technical discussions, design reviews, manufacturability reviews, and cross-functional engineering meetings.
• Support continuous improvement initiatives across engineering documentation, configuration management, and product development workflows.
