the posting
There was a time when all of America believed that the future of the physical world could be radically different. 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 Design Engineering role is responsible for developing flight hardware for new and existing airframes. You will serve as the extreme owner of the product from concept through qualification, and eventually production handoff. Your day will consist of designing, analyzing, and building a wide range of fluid and structural systems. Most importantly you will own the relationship between customer level requirements and the build/test engineering teams.
Responsibilities:
Own design and prototyping of new mechanical hardware
Develop state-of-the-art, manufacturable, avionics hardware (buttons, switches, dials), flow control devices (valves, regulators, solenoids) or mechanisms (actuators, switches, pistons). Question requirements, simplify, and accelerate aerospace component deliveries
Generate and maintain detailed drawings, component specifications, analysis and risk assessments. We believe design engineers should perform their own concept design, technical analysis and first unit builds – we minimize compartmentalized duties wherever possible
Spearhead root cause investigations that arise in development, production, and test. Implement corrective actions to prevent repeat failures
Set the standard for rigorous component design and qualification testing. As a member of an early-stage startup, you will be integral in defining company design and testing policies
Act as the extreme owner for the parts you work on, you will be expected to be the ultimate authority for components you develop and be able to work closely with customers and manufacturers as problems arise
Prototype new components at our in-house R&D lab. You will be expected to be intimately involved with any prototype development
Work with test engineering to define and execute qualification plans
Work closely with build engineers to ensure new designs are manufacturable at production facilities and DFM feedback is implemented
Basic Qualifications:
Bachelor's or advanced degree in aerospace engineering, manufacturing engineering, materials engineering, mechanical engineering or engineering physics
1+ years of mechanical or fluids design, analysis, or build experience (student project team and internship experience qualifies)
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 designing, building, testing and troubleshooting mechanical systems
Experience with pressurized components (valves, regulators, tubes, pipes, etc.)
Experience with finite element analysis (FEA) software packages
Experience with Siemens NX or other similar CAD package
Experience using test instrumentation and control components (e.g. pressure transducers, thermocouples, resistance temperature detectors, relays, solenoid valves, etc.)
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
