Mechanical Engineer II

# Mechanical Engineer II – Rugged Electronics Product Development ## About Orion Edge We are an agile, early-stage startup in a rapid growth phase, developing next-generation electronic warfare (EW) and digital disruption equipment. Our mission is to deliver cutting-edge capabilities to the modern warfighter at speed. Orion Edge is currently delivering systems to the US Army and USSOCOM, and we are scaling quickly to support the broader Department of Defense (DoD). If you thrive in a fast-paced environment where your work directly impacts national security and you have the opportunity to scale your career with a growing company, you belong here. ## Position Overview As a **Mechanical Engineer II**, you will design and develop compact, ruggedized electronic and electromechanical products that withstand harsh operational environments. This is a hands-on, early-to-mid-career product design role where you will own the physical packaging of our technology-from initial enclosure concepts, sealing, and thermal management to prototyping, testing, and production. You will work closely with electrical, RF, and PCB engineers to package complex electronics into deployable defense systems. If you have a passion for building physical hardware, love solving spatial puzzles, and want to see your designs transition quickly to the field, you belong on this team. ## Education Requirements - **Bachelor of Science (B.S.)** in **Mechanical Engineering** or a closely related engineering discipline. ## Key Responsibilities - **Mechanical & Housing Design:** Design compact enclosures, brackets, thermal components, connector interfaces, and small mechanisms using SolidWorks. - **Thermal & Physical Modeling:** Run first-order hand calculations and basic thermal/mechanical simulations to design optimized heat sinks, fans, and ducting. - **ECAD-MCAD Collaboration:** Collaborate with electrical and PCB engineers to manage board outlines, keepouts, component heights, and connector placement. - **Prototype & Validate:** Build, instrument, and test physical prototypes (for fit, thermal performance, and environmental sealing) to validate design assumptions. - **DFM & Production Support:** Apply Design for Manufacturability (DFM) principles for CNC machining, sheet metal, injection molding, and additive manufacturing; manage the transition from prototype to production. - **Documentation & Release:** Author clean engineering drawings, specifications, assembly instructions, bills of materials (BOMs), and engineering change notices. ## Required Skills & Experience - **Professional Experience:** 3 to 5 years of relevant mechanical design experience. *We highly value hands-on experience and will consider substantial internships, co-ops, senior design projects, military technical experience, or competitive engineering teams (e.g., Formula SAE, robotics).* - **3D CAD Proficiency:** Strong experience using **SolidWorks** (or similar parametric 3D CAD tool) to create clean models, assemblies, configurations, and basic 2D drawings. - **Engineering Fundamentals:** Strong grasp of statics, mechanics of materials, heat transfer, thermodynamics, fits, and manufacturing tolerances. - **Tolerance & GD&T Basics:** Practical understanding of mechanical tolerances, limit stacks, and the application of basic GD&T principles. - **Hands-on Assembly & Test:** Proven track record of building, testing, or troubleshooting physical hardware in a lab, shop, or maker setting. - **Design Verification:** Experience testing physical hardware and utilizing test results to validate or iterate on mechanical designs. ## Preferred Qualifications - **Rugged Electronics Packaging:** Experience packaging electronics, radios, robotics, or avionics into IP-rated, sealed enclosures (using gaskets, O-rings, and sealed connectors). - **Advanced SolidWorks:** Experience with complex assemblies, configurations, surfacing, multibody parts, and detailed assembly drawings. - **Thermal Analysis & Simulation:**…
