Shift5 is building a data platform for onboard operational technology (OT) that delivers cybersecurity, predictive maintenance, and compliance capabilities to defense and commercial fleets. We are seeking a Mechanical Engineer to drive the mechanical design, development, and integration of cutting-edge rugged hardware for data collection and processing on the edge.
This role sits at the intersection of mechanical design, hardware lifecycle management, and aerospace/defense compliance. You will own the full hardware development lifecycle, from initial design through field deployment. This is an active, in-office and field-oriented position requiring hands-on engagement with customer platforms, technical fluency in mechanical design, and relentless drive to solve complex integration challenges.
Key Responsibilities:
- Design and develop ruggedized electronic enclosure assemblies and custom mechanical installation kits using first-principles physics and engineering analysis to comply with military and aerospace standards (MIL-STD-810, DO-160).
- Own CAD modeling and PLM for ruggedized electronic assemblies, generating production drawings with GD&T under applicable standards.
- Partner with vendors and suppliers to manage tooling, procurement, BOMs, and design revisions supporting manufacturing and field deployment.
- Travel and deploy into the field to work directly alongside customers, leading on-site mechanical fit checks, installations, and supporting integration testing and system verification.
- Prototype, test, and validate mechanical designs against real-world structural, thermal, environmental, and integration requirements.
- Translate field integration findings into actionable mechanical design improvements, resolving interface, fitment, environmental, and manufacturability issues.
Requirements:
- 3+ years of experience in mechanical engineering of rugged electrical enclosure design, bracket/installation kit design, or hands-on hardware integration (7+ years for Senior level consideration).
- Proficiency in 3D CAD and PLM tools, including SolidWorks and Siemens NX & Teamcenter, for detailed design, drafting, GD&T, and assembly validation.
- Strong engineering fundamentals across first-principles physics, FEA, sheet metal fabrication, and advanced manufacturing methods.
- Hands-on experience with mechanical prototyping, assembly, integration, and testing.
- Comfort operating in fast-paced, regulated environments involving MIL-STD-810 (shock, vibration, environmental) and DO-160 standards.
- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field.
- Highly self-motivated with strong bias for action, proactive problem-solving skills, and willingness to travel as needed.
- Active U.S. Secret security clearance, or ability and willingness to obtain one.
Preferred:
- System-level electromechanical integration experience for defense/aerospace platforms, including cable routing, thermal management, structural load paths, and mounting constraints.
- Experience conducting vendor surveys, evaluating component supplier changes, and working closely with supply chain and manufacturing teams.
- Experience in AS9100 certified environments and familiarity with IPC standards.
