Summary

Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other’s ideas stronger. Here, you’ll do more than join something — you’ll add something. Video Engineering is seeking a strong, experienced, self-motivated Software Development Engineer in Test with a passion for making all Apple product experience the best it can be. You will be working on the latest Apple products, ensuring that the video experience is the best in the world!

Description

In this role, your main responsibility will be test design and development for video processing frameworks and low-level software of video codecs, covering both functionality verification and quality measurement across all iOS/macOS/tvOS/visionOS platforms. The work targets image & video encoding/decoding, editing/post-processing, and machine learning based technologies.

Your daily tasks will include developing software and tools to validate algorithms and code changes of projects, designing test cases, and architecting test harnesses. You will implement tests in C/C++, Objective-C, Swift, and Python/Shell scripting using test frameworks. Additionally, you will automate workflows in testing and quality evaluation pipelines, triage and root-cause failures, and drive early test strategy and planning. You will also build LLM-based tools and agentic workflows that extend what these pipelines can automate at scale.

You will partner with R&D engineering teams and both internal and external cross-functional partners to ensure image and video frameworks/firmware/drivers deliver the highest quality video experience.
