Mechanical Engineer II

Orion Edge Group • Town "n" Country, FL

1d • $100,000 - $110,000 • Onsite

About The Position

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.

Requirements

• 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).
• Strong experience using SolidWorks (or similar parametric 3D CAD tool) to create clean models, assemblies, configurations, and basic 2D drawings.
• Strong grasp of statics, mechanics of materials, heat transfer, thermodynamics, fits, and manufacturing tolerances.
• Practical understanding of mechanical tolerances, limit stacks, and the application of basic GD&T principles.
• Proven track record of building, testing, or troubleshooting physical hardware in a lab, shop, or maker setting.
• Experience testing physical hardware and utilizing test results to validate or iterate on mechanical designs.

Nice To Haves

• Experience packaging electronics, radios, robotics, or avionics into IP-rated, sealed enclosures (using gaskets, O-rings, and sealed connectors).
• Experience with complex assemblies, configurations, surfacing, multibody parts, and detailed assembly drawings.
• Familiarity with thermal interface materials (TIMs), heat pipes, or vapor chambers, alongside experience using simulation software (e.g., SolidWorks Flow Simulation, Ansys, Icepak, FloEFD, or Flotherm).
• Training or project-level application of GD&T per ASME Y14.5 and formal tolerance-stack calculations.
• Familiarity with collaboration tools such as Altium MCAD CoDesigner, CircuitWorks, or IDX/IDF.
• Experience working directly with machine shops, sheet metal fabricators, 3D printing bureaus, or molders.
• Exposure to environmental compliance testing (vibration, drop, thermal cycling, or water/dust ingress).
• Advanced degrees.
• You love physical prototyping and are eager to work with shop tools, 3D printers, and thermal testing instrumentation.
• You understand that CAD and simulation are tools, and you always verify digital models against hand calculations and real-world physical tests.
• You actively communicate across engineering boundaries, asking smart questions to discover hidden electrical or software constraints.
• You are comfortable researching unfamiliar manufacturing processes or components and welcome technical feedback to sharpen your skills.
• You take pride in clean models, organized CAD structures, and robust documentation.

Responsibilities

• Design compact enclosures, brackets, thermal components, connector interfaces, and small mechanisms using SolidWorks.
• Run first-order hand calculations and basic thermal/mechanical simulations to design optimized heat sinks, fans, and ducting.
• Collaborate with electrical and PCB engineers to manage board outlines, keepouts, component heights, and connector placement.
• Build, instrument, and test physical prototypes (for fit, thermal performance, and environmental sealing) to validate design assumptions.
• Apply Design for Manufacturability (DFM) principles for CNC machining, sheet metal, injection molding, and additive manufacturing; manage the transition from prototype to production.
• Author clean engineering drawings, specifications, assembly instructions, bills of materials (BOMs), and engineering change notices.
