Mechanical Design Engineer, Defense Structures

Location: Chatsworth

About Machina Labs:

Engineering moves at software speed. Manufacturing doesn'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're building the manufacturing infrastructure that 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 looking for a motivated, detail-oriented, and technically strong Mechanical Design Engineer to join our Aerospace and Defense team. This role will focus on the mechanical design, producibility, and design-for-manufacturability of structural defense products, including missile structures, hypersonic vehicle components, UAV structures, and other integrated metallic assemblies.

As a Mechanical Designer, you will work closely with engineering, manufacturing, business development, and customer teams to translate customer requirements and product concepts into manufacturable designs. You will support the development of metallic structures, tooling concepts, assembly approaches, and producibility recommendations that enable rapid, scalable production using Machina Labs' advanced manufacturing capabilities.

Success in this role requires strong mechanical design fundamentals, practical manufacturing judgment, attention to detail, and the ability to work in a fast-paced technical environment. The ideal candidate is comfortable working with incomplete information, can identify manufacturability risks early, and can propose clear design changes that improve cost, lead time, quality, and production scalability.

This role is well suited for someone who understands that the best design is not only technically sound, but also buildable, inspectable, repeatable, and scalable.

Key Responsibilities:

* Create and modify mechanical designs for structural defense products, including missile, hypersonic, UAV, and aerospace metallic structures.

* Support design-for-manufacturability reviews for customer-provided designs, models, drawings, and technical data packages.

* Identify producibility issues related to forming, welding, machining, trimming, fixturing, assembly, inspection, and integration.

* Develop clear manufacturability recommendations and design change requests to support customer design improvements.

* Generate CAD models, layouts, detailed drawings, assemblies, bills of materials, and supporting technical documentation.

* Work with internal engineering and manufacturing teams to align product designs with Machina Labs' robotic forming and advanced manufacturing processes.

* Support concept development for integrated structures, including formed panels, stiffened structures, tanks, aeroshells, frames, brackets, ducts, and other metallic components.

* Translate customer requirements into practical design inputs for manufacturing development, quoting, prototyping, and production planning.

* Participate in internal and external design reviews, manufacturability reviews, and technical interchange meetings.

* Support rapid iteration of designs based on customer feedback, manufacturing results, inspection data, and production lessons learned.

* Collaborate with manufacturing engineers, mechanical engineers, weld engineers, quality engineers, and program teams to resolve design and production issues.

* Help develop standard design guidelines for manufacturable metallic structures using Machina Labs' processes.

Maintain a high level of technical rigor, configuration discipline, and documentation quality.

Required Background &

Experience:

* Bachelor's degree in Mechanical Engineering.

* 3+ years of experience in mechanical design, aerospace design, defense product design, or manufacturing-focused product development.

* Experience using parametric CAD software to create parts, assemblies, and drawings, such as Solid Works,…
