Senior Mechanical Engineer

AIM • Seattle, WA

5d • Onsite

About The Position

AIM builds autonomy for the real world - robots that move mountains. Our systems combine software, hardware, robotics, and mission-critical infrastructure into ruggedized, safety-critical machinery operating in some of the harshest environments on earth. Our customers depend on our machines to work reliably in dust, mud, vibration, shock loads, thermal extremes, and unpredictable jobsite conditions. Mechanical engineering is at the foundation of this mission. Our hardware must be robust to all the conditions the machines work in, tolerating shock, vibration, and environmental conditions from full desert sun to deep snow. The system must be field-serviceable, and deeply integrated with autonomy, electrical, and software systems. We design mechanical systems that perform not just in CAD or simulation, but in real-world chaos: misalignment, wear, debris, hydraulic spray, operator variability, and global deployment. We're scaling fast and building the mechanical engineering foundation that will define the next century of construction and autonomy.

Requirements

• BS degree in Mechanical Engineering or equivalent practical experience.
• 7+ years of experience in mechanical engineering and product development.
• Strong mechanical fundamentals: machine design, structural analysis, thermal analysis & modeling
• Proficiency in CAD tools (SolidWorks, OnShape, or similar).
• Experience performing component-level FEA and mechanical simulation.
• Hands-on experience with prototyping, bench/field testing, environmental testing, and failure analysis.
• Experience working with component vendors, sensor vendors, and assembly houses.
• Ability to work cross-functionally in collaborative, fast-paced environments.
• Ability to occasionally travel to production sites and customer deployments.

Nice To Haves

• Experience designing ruggedized systems for construction, mining, agriculture, or heavy equipment.
• Experience designing welded structures, steel mounting systems, and fabrication-driven assemblies.
• Experience with environmental sealing, thermal management, vibration/shock mitigation, or fatigue engineering.
• Working knowledge of electrical systems, sensors, compute integration, or electromechanical assemblies.
• Experience with welding, machining, metal fabrication, and industrial manufacturing methods.

Responsibilities

• Architect & Deliver Robust Mechanical Systems: Own major mechanical subsystems such as sensor suites, compute enclosures, LiDAR and camera mounts, structural brackets, safety housings, and environmental protection systems. Create concepts and designs for manufacturable, field-serviceable solutions to challenging engineering problems. Transform customer needs and product requirements into mechanical architectures and integration strategies across machine platforms.
• Design, Analyze & Model: Produce high-quality CAD (SolidWorks, OnShape, or similar) to communicate design intent and critical dimensions and properties to fabrication and manufacturing partners. Take CAD from quick concept and prototyping activities, all the way to full production designs, with detailed drawings, tolerances, and inspection plans. Perform advanced mechanical analysis to inform you designs - from numerical analysis through to FEA as you consider material selection and designs to meet the environment your designs need to operate in, including fatigue, vibration, shock, and thermal considerations. Evaluate tradeoffs between manufacturability, reliability, cost, weight, and serviceability.
• Prototype, Test & Validate: Prototype designs using internal and external fabrication resources; iterate quickly based on fit, function, and field feedback. Execute rigorous verification plans, including ingress testing, vibration & shock testing, thermal testing, fit checks, and field trials. Conduct failure analysis and drive corrective-action loops that meaningfully improve robustness.
• Integrate Across Disciplines: Collaborate closely with EE, SWE, Autonomy, Systems, TPMs, Deployment Engineers, and OEM partners to ensure seamless mechanical-electrical integration. Clarify ambiguous requirements early by surfacing mechanical risks and installation constraints. Ensure designs account for operator behavior, jobsite realities, and real-world tolerances.
• Manufacture & Scale: Create detailed manufacturing drawings and documentation for production. Work with vendors, fabricators, and assembly houses to build reliable supply chains and ensure manufacturability at scale. Improve manufacturing yield and reduce manufacturing times through DFM and serviceability-driven design improvements.
• Raise the Mechanical Engineering Bar: Mentor and guide junior and mid-level mechanical engineers; lead by example in design reviews and technical discussions. Improve mechanical engineering practices: validation plans, part libraries, design patterns, documentation, and standards. Help define what mechanical engineering excellence looks like at AIM.

Benefits

• Competitive compensation, equity, medical/dental/vision, 401(k), life insurance.
• Travel opportunities to customer jobsites across the U.S., Australia, Europe, Africa, South America, and more.
• company funded medical, dental, vision, 401k, life insurance, gourmet food & perks
• Experience a strong onsite collaboration (AIM offices, labs and proving grounds on the east side of the Greater Seattle area)
• Have an opportunity to travel to unique sites around the world (Americas, Australia, Africa & more)
