OptoMechanical Engineer III, Matrix Team

Key job responsibilities

• Collaborate with experienced cross-disciplinary teams to develop, design, and bring to market innovative devices and services
• Design and build innovative technologies in a large distributed computing environment and help guide fundamental changes in the industry
• Create solutions to run predictions on distributed systems with exposure to advanced technologies at incredible scale and speed
• Build distributed storage, index, and query systems that are scalable, fault‑tolerant, low cost, and easy to manage/use
• Architect and oversee the development of advanced sensor and optoelectronic systems for Amazon Robotics. This role requires a seasoned engineer who can define system architectures, set technical direction, and make informed trade‑offs across electrical, mechanical, and software interfaces.
• Own product development from concept through production, including requirements definition, design, prototyping, validation, DVT planning, and release to manufacturing. The engineer will design and analyze sensor modules, including optoelectronics packaging, PCBA layout, signal integrity, thermal considerations, and environmental/EMI compliance.
• Guide cross‑functional technical choices, ensuring alignment across interdisciplinary teams, and providing structure in ambiguous problem spaces. The engineer will evaluate and integrate new sensing technologies, oversee characterization of internally developed and off‑the‑shelf sensors, and drive documentation such as functional specs, verification plans, and test procedures.
• Mentor junior engineers, guide design reviews, manage external development partners, and communicate clearly with leadership through concise written and verbal updates. This role demands strong ownership, technical depth, and the ability to deliver results in fast‑paced environments.

A day in the life
