Software Engineer - Systems & Rendering Performance (Freeform), Vision Products Software

The visionOS Freeform team is looking for a senior engineer to deliver smooth, responsive, and power-efficient spatial experiences on Apple Vision Pro. This role focuses on rendering performance, frame pacing, and cross-layer systems debugging in close partnership with platform and performance teams across Apple. The work spans application behavior, system scheduling, memory, and rendering, with an emphasis on translating real-world usage into durable, production-ready improvements.

As the product and platform mature, this role is expected to evolve and contribute broadly to complex systems challenges across visionOS, iOS, and macOS.

Description

You will work at the intersection of application behavior, rendering, and system infrastructure, investigating performance and power issues and driving high-impact fixes. You will translate architectural direction into concrete execution, influence technical decisions through careful measurement and engineering judgment, and raise quality through code reviews, design discussions, and mentorship.","responsibilities":"Design, implement, and maintain performance-critical systems related to rendering, frame scheduling, and responsiveness for Freeform on visionOS
