About The Position

The Sr. Software Development Engineer on the Duro Design team builds and ships product experiences that hardware engineers rely on every day. You’ll work across our modern stack—from frontend interfaces to backend architecture—to deliver elegant, performant, and scalable solutions. This role partners closely with product, design, and engineering teammates in a fast-moving, highly autonomous environment. We’re looking for engineers who think end-to-end, embrace experimentation, and leverage modern AI-powered workflows to move with speed and precision. This is a hybrid role based in Los Angeles, CA (3 days per week in office). At Duro, AI is integrated into our engineering workflows. Engineers leverage AI-powered development environments to orchestrate tasks, structure context, and accelerate delivery while maintaining high standards of craftsmanship. We value architectural intuition, precision in communication, pattern recognition, product taste, and intellectual curiosity. We optimize for engineers who can take ambiguous requirements and transform them into measurable, high-impact product outcomes.
