Amazon MGM Studios is seeking a Software Development Engineer III to lead technical development for our Studio in the Cloud (SITC) platform. SITC is transforming entertainment content creation by moving all major production and post-production workflows from traditional on-premises infrastructure to AWS cloud-based solutions. This initiative encompasses nine core workflows—Dailies, Editorial, VFX, Sound, Conform, Color, Mastering, QC/Delivery, and Remote Production—representing the complete content creation lifecycle from Original Camera Footage (OCF) ingestion through final delivery. In this role, you will lead software development for critical SITC platform components, owning team-level architecture and providing technical direction for multi-engineer projects. You may own architecture for specific workflows (e.g., media transcoding and processing engine, real-time collaboration infrastructure, GPU-accelerated rendering system, or content delivery and QC automation), designing and implementing distributed systems that enable creative professionals to work globally using industry-standard tools integrated on AWS. Your work will solve complex technical problems including high-bandwidth media transfer, sub-second latency playback for 4:4:4 10-bit video, elastic GPU compute for rendering workloads, and multi-region disaster recovery for productions that cannot tolerate downtime. As an SDE III, you will work both tactically and strategically, contributing to 1-2 year technical strategy while delivering hands-on technical implementations. You will lead multi-engineer projects, provide system-wide design guidance, and ensure your team's software is architected for scale, performance, and long-term maintainability. You will integrate with leading creative tool providers including Avid, Adobe, Colorfront, and Blackmagic, understanding their technical requirements and ensuring optimal performance in cloud environments. Your systems will support Amazon MGM Studios' production slate spanning 150+ titles annually across International Originals and Global Originals. This role requires deep technical expertise in distributed systems, media processing pipelines, high-performance computing, and cloud infrastructure. You will architect solutions that handle terabyte-scale data (each production generates 10-50TB), maintain sub-second response times for interactive creative workflows, and provide elastic compute scaling for rendering workloads that must complete on production schedules. Success requires balancing technical excellence with pragmatic delivery—building scalable architectures while meeting production timelines and maintaining the creative quality that content creators demand.
