The engineers of the mid-1900s put a man on the moon in eight years, designed and built planes and submarines from scratch in under three, and conceived of building things we wouldn’t even be able to dream up today. Today, the last of the engineers who imagined and built these systems are retiring. As they go, we lose not only the engineering knowledge gained from their decades of imagination and trial-and-error, but also the spirit that made that imagination possible. Amca is working day-in and day-out to restore America’s ability to engineer anything that our critical systems depend on, and reinvigorate the cycle of creation that allows imagination to shape physical reality. We rapidly develop and manufacture new critical components and subsystems required to build and sustain the planes, military vehicles, and core infrastructure America needs. By restoring the capability of our antiquated supply chains, we increase the country’s capacity to imagine and realize new systems, and make a physical world that looks very different from today. Overview: The Mechanical Build Engineering role is responsible for owning the build procedures used to develop qualification hardware, and iterate on the initial builds to ensure highly reliable production level builds at our factories once product maturity has been achieved. You will serve as the extreme owner for build process of the parts we design. Your days will consist of hands on R&D for new build methodologies and specifications, while also working closely with the design engineering team to ensure design for manufacturability of our new products. Responsibilities: - Develop build methodology from industry standards and conduct cutting edge R&D to improve on our component manufacturing processes and unlock new methods - Oversee the assembly and manufacturing procedures for both new and existing hardware - Act as the extreme owner of DFM changes to part drawings. You will be empowered to make changes to the drawings as required to eliminate repeat failures - Conduct development campaigns for new manufacturing methods and write specifications on manufacturing best practices based on real world data for the design engineers to abide by - Trade purchasing commercial build/manufacturing capabilities off the shelf against designing and developing the capabilities in house - Act as the extreme owner for various manufacturing methods, you will be the ultimate source of information for design engineers on how machines work and how to best optimize parts for various methods - Ideate and implement tooling, enabling high-quality build of Amca hardware - Identify, plan, and execute capital equipment, machine, and layout upgrades to meet changing needs - Partner with engineering and production teams to generate ideas, designs, and improvements for current and next-generation vehicles - Assist design engineers in guiding new designs from concepts to qualified, production-capable aerospace components - Prototype new components at our in-house R&D lab. You will be expected to be intimately involved with any prototype development Basic Qualifications: - Bachelor's or advanced degree in aerospace engineering, manufacturing engineering, materials engineering, mechanical engineering or engineering physics - 1+ years of engineering experience in manufacturing, design, test, or development (internship and project team experience is applicable) - Strong understanding of engineering first principles, specifically with regards to thermodynamics, fluid dynamics, and solid mechanics Preferred Skills and Experience: - Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to optimize modern aerospace production and design processes - 2+ years of professional experience in the field of aerospace/mechanical engineering - 2+ years of experience with GD&T concepts - Strong project management skills and effective communication of technical concepts across multi-disciplinary teams - Experience with the building and testing of fluid and/or electrical systems - Experience with the build and test of pneumatic, hydraulic, and structural assemblies - Experience with scientific computer science languages (Python, MATLAB, or similar) - Experience with Siemens NX or other similar CAD package - ## Experience with DFM improvement projects Additional Requirements: - Travel to vendors and other Amca sites as needed - Able to work flexible hours and occasional weekend support as needed Annual Salary Range $100,000—$130,000 USD This position requires use of information which is subject to the International Traffic in Arms Regulations (ITAR).
