Senior Mechanical Engineer

Overview

A fast-growing robotics and industrial automation startup in the Greater Boston area is hiring a full-time Senior Mechanical Engineer to help develop next-generation robotic systems that are transforming automotive service operations. This role focuses on the design, development, testing, and production release of complex mechatronic systems, combining mechanical engineering, robotics, automation, and industrial product development. The position offers the opportunity to work on highly innovative robotic solutions in a hands‑on startup environment where engineers have significant ownership and direct influence over product development from concept through deployment.

This is an ideal opportunity for an experienced mechanical engineer who enjoys building complex machines and seeing products move rapidly from prototype to production. The company is looking for someone who can combine strong analytical design skills with practical hands‑on engineering, working closely with electrical, software, controls, and perception teams to create robust robotic systems. You'll play a key role in shaping product architecture, improving manufacturability, and helping establish engineering processes as the organization continues to scale.
