Senior Mechanical Engineer

Arrive AI Inc.•Fishers, IN

About The Position

We are seeking a Senior Mechanical Engineer to lead the evolution and scaling of our next-generation autonomous delivery hardware. This is a high-impact, hands-on role for a technical architect who thrives at the intersection of physical design, robotic intelligence, and systemic reliability. You will own the mechanical integrity of our Arrive Point hardware, moving fluidly between digital twin simulation, rapid prototyping, and large-scale manufacturing oversight. In this role, you aren't just designing parts; you are engineering the physical foundation for autonomous intelligence. You will balance the "speed vs. rigor" trade-off, ensuring that our AI-driven features—from robotics intelligence to predictive sensors—are robust, manufacturable, and field-ready. Design Digitally First: Use expert-level CAD (Creo preferred) and simulation tools to concept, validate, and iterate. You’ll lead "digital-first" workflows to accelerate development and eliminate costly physical revisions Coordinate Across Disciplines: Work hand-in-hand with Electrical, Robotics, and Systems engineers. You will lead the "war room" conversations, resolving technical trade-offs to ensure seamless integration of PCBs, sensors, and compute modules. Accelerate Prototype-to-Production Cycles: Oversee high-velocity prototyping to test features and enhance current builds based on real-world field data, while simultaneously partnering with external design firms and Contract Manufacturers (CMs) to ensure those innovations are optimized for unit economics, DFM, and high-volume. Technical Leadership: Provide mentorship to the engineering team, fostering a culture of rigorous problem-solving, documentation excellence, and creative engineering.

Requirements

5+ years of experience in mechanical engineering, preferably in robotics or autonomous systems.
Strong CAD proficiency (SolidWorks preferred) and experience designing for manufacturability.
Proven success working with contract manufacturers and design partners.
Comfort moving between design, hands-on prototyping, and documentation.
Experience working in fast-paced, iterative environments with evolving requirements.

Nice To Haves

Familiarity with AI-powered or IoT-integrated hardware is a plus.
