About ATI: Automated Tire (ATI) is on a mission to reinvent tire changing and wheel balancing using cutting-edge robotics. We are transforming a process that hasn't fundamentally changed in decades into an automated, high-performance system built for the future of automotive service. Founded by experienced entrepreneurs and backed by leading players across the automotive and tire industries, ATI is building technology that will redefine how cars are serviced. Our team combines deep robotics expertise with real world deployment, moving fast from prototype to production and scaling solutions directly in the field. This role offers an exciting opportunity to work at the forefront of robotics and industrial automation, applying expert-level mechanical engineering to develop advanced mechatronic systems. If you are a mechanical engineer with a passion for solving complex automation challenges, we encourage you to apply and become a key part of our innovative team. Position Overview: We are looking for a highly skilled and experienced Senior Mechanical Engineer with expertise in complex mechatronic system design, contributing to the delivery of multidisciplinary industrial robotic products. The ideal candidate will have hands-on experience designing, fabricating, assembling, documenting, and testing mechatronic systems that include multi-axis actuation. The candidate will work in a small team of engineers building a novel robotics and automation solution. As we are a small startup, the role will have a large amount of autonomy, and the candidate must be comfortable working in a fast-paced environment where requirements may shift and decisions need to be made with limited information. Key Responsibilities: Mechatronic Hardware Design: Design complex electro-mechanical systems from concept through production release, including: Design elegant hardware solutions that function with efficiency and simplicity. Specifying actuators, motors, and sensing technologies (encoders, load cells, proximity sensors, etc.). Validating your own designs through hands-on prototyping and testing. Documentation & Quality: Drive high standards for engineering documentation and design reviews for production release. Communicate with vendors effectively to drive rapid design cycles through completion. Collaboration: Work with cross-functional teams, including electrical, controls, software, and perception engineers, to ensure solutions are aligned and integrated with product goals. Requirements BS in Mechanical Engineering, Robotics Engineering, or equivalent. 5+ years of applicable professional experience in the robotics or automation industry. Demonstrated experience designing electro-mechanical systems from concept through product release/shipment at scale (industrial products preferred). Expertise in the design and specification of actuators, motors, and sensing technologies (encoders, load cells, proximity sensors, etc.). Experience validating designs with structural finite element analysis (FEA). Proficient with Onshape, Solidworks (or equivalent) Proficient creating and interpreting engineering drawings with Geometric Dimensioning and Tolerancing (GD&T). Experience with Product Lifecycle Management (PLM) systems such as Arena PLM or equivalent, including document control, revision management, engineering change order (ECO) processing, and bill of materials (BOM) structuring Proven ability to perform hands-on, low-level debugging and systematic troubleshooting of complex mechatronic systems in real-world environments. Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to drive innovative solutions from concept through production in a fast-paced startup environment. Please submit your Portfolio, or Sample of your work, along with your application Preferred Qualifications: MS or PhD in Mechanical Engineering. Proven experience applying Design for Manufacturing (DfM) principles to low-to-medium volume industrial systems. Expertise in system dynamics, simulation, modeling, and vibration analysis. Experience developing free body diagrams and governing equations for electro-mechanical systems. Experience performing static and dynamic load calculations and kinematic analysis. Experience working with industrial controls systems. Experience developing engineering documentation processes from the ground up. (Engineering drawing formats , part numbering, CAD PDM, etc.). Matlab or Python experience.
