In the Amazon Fire TV team, we are creating the most engaging entertainment platform for the whole family, worldwide. Be part of a fast-paced, agile and innovative team who is delivering new experiences to Fire TV devices in a startup like environment.

We are looking for a Senior System Development Engineer to join our Picture Quality (PQ) engineering team in Shenzhen. In this role, you will be at the intersection of software, hardware, and manufacturing — owning end-to-end PQ system quality for Amazon's smart TV devices and driving PQ excellence across our ODM partner ecosystem. You will work closely with display hardware teams, ODM/OEM partners, and cross-functional software engineers to define, implement, and validate PQ standards that set the bar for the industry.

This is a high-impact, highly technical role that requires both deep system-level thinking and hands-on execution. You will not just define standards — you will build the tools, algorithms, and processes that make those standards real.

Key job responsibilities
As a Senior System Development Engineer on the PQ team, you will:

• Own the end-to-end PQ system architecture for Amazon 1P devices, spanning SW feature development, display tuning, and factory quality integration.
• Develop and maintain PQ software algorithms including picture quality features, gamma/LUT calibration pipelines, white point correction, and color management systems and etc.
• Define and enforce Amazon's PQ tuning standards across ODM partners, ensuring consistent visual quality across global markets.
• Lead PQ certification programs including Dolby Vision, HDR10 and HDR 10+,coordinating with third-party certification labs and internal stakeholders.
• Collaborate with display hardware engineers and ODMs to understand panel characteristics and translate hardware capabilities into optimized SW tuning parameters.
• Drive root cause analysis for PQ defects identified in factory, field, or competitive benchmarking, and implement systematic fixes at the SW or process level.
• Partner with ODM engineering teams to resolve PQ gaps during production, ensuring quality gates are met before launch.
• Mentor junior engineers and contribute to the technical growth of the PQ team.
• Influence product roadmap by providing data-driven PQ assessments and competitive analysis.

A day in the life
As a System Development Engineer on the System Engineering team, no two days are alike. You'll tackle new problems and development challenges across different layers, learning and growing rapidly as you go. This role will provide you with exceptional breadth, deepening your understanding of CS fundamentals and best practices in consumer electronics, operating systems, and system architecture. You'll have high visibility across our products and direct connection to customers who rely on Fire TV as their daily streaming device, with abundant opportunities to influence and make a meaningful difference.
