Job description

Mechatronics CAD Design Engineer (Outdoor Robotic Enclosure Systems) | Motion Mechanisms & Weatherproof Design

About the role

We’re looking for a Mechatronics CAD Design Engineer to take an existing autonomous ground hardware system and raise it to industry-grade standards. The work is very hands‑on: improving mechanical design for movable doors/panels, increasing weather resistance and waterproofing, and making the product more reliable, serviceable, and production‑ready—without overcomplicating it.

What you’ll do

• Improve and industrialize an existing mechanical system into a robust, production‑ready product with strong reliability and serviceability.
• Design and refine movable door/panel mechanisms (hinges, sliders, latches, linkages, hard stops, dampers) for smooth operation and repeatability.
• Develop and validate weatherproof and waterproof mechanical design: sealing concepts, gasket grooves, labyrinth features, drainage paths, IP‑oriented design practices, and corrosion protection.
• Integrate electromechanical components such as motors, actuators, gearboxes, belts/lead screws, springs, locks, sensors, and limit switches into clean mechanical layouts.
• Improve structural stiffness and alignment for mechanisms under real‑world conditions (dust, rain, vibration, temperature changes), including tolerance considerations and wear points.
• Design quick‑service mechanical joiners and modular subassemblies for fast maintenance and replacement in the field.
• Create complete CAD deliverables: 3D models, assemblies, drawings, BOMs, tolerance notes, and assembly instructions suitable for fabrication and production.
• Work closely with fabrication and production teams to prototype, test, and iterate quickly based on real build feedback.
• Collaborate with electrical and controls teams to ensure good routing/protection of cables and sensors, safe actuator integration, and reliable interlocks.
• Support verification testing and improvements based on field issues, root‑cause analysis, and engineering change implementation.

What we’re looking for

• 2+ years experience in mechanical/mechatronics CAD design for robotics, automation, industrial products, outdoor equipment, or similar systems.
• Strong CAD skills in SolidWorks
• Solid understanding of mechanisms and design fundamentals: fasteners, tolerance stack‑up, alignment, bearings, materials, wear, vibration, and practical DFM/DFA.
• Comfort designing for real‑world deployment: sealing, corrosion prevention, drainage, service access, and durability.
• Ability to produce shop‑ready drawings and work closely with technicians to get parts built and working.

Nice to have

• Exposure to IP‑rated enclosure design (IP54/IP65/IP67 concepts), gasket selection, sealing strategies, and outdoor thermal considerations.
• Experience with sheet metal, machined parts, castings, or composite enclosures.
• Basic understanding of actuator sizing, load paths, and mechanism testing.
• Familiarity with PDM/PLM and engineering change workflows.

Why join us

• You’ll work on a product that’s already real—and make it industrial, rugged, and field‑ready.
• Strong ownership: your design decisions will directly improve reliability and user experience.
• Fast iteration loop with direct access to fabrication and testing.
• Performance‑based recognition and growth opportunities as projects scale.
