Engineering Manager, Media Foundations and Delivery

 Video consumption on our platform is experiencing massive organic growth, and we are heavily investing in integrating media as a functional layer of human discussion.

We are looking for an Engineering Manager to lead our Media Foundations & Delivery team. In this role, you will help transition media into a first-class citizen with a strong technical foundation and extensible architecture. You will lead a cross-functional group of Backend, iOS, Android, and Web engineers to evolve our media stack and to unlock the next phase of growth at Reddit.

What You'll Do

• Drive Infrastructure Modernization: Lead the architectural shift to elevate media to a first class citizen.
• Optimize Playback & Delivery: Own key success metrics related to Quality of Services (QoS), including Time to First Frame (TTFF), stall/rebuffer rates, exits before video screen (EBVS). You will define the path to ensure reliable streaming for all of our users across the globe.
• Manage Global Distribution: Partner closely with our infrastructure teams to define how to scale media via Content Delivery Networks (CDNs), edge computing, and caching strategies.
• Standardize Formats: You will drive the standardization of our stack, from streaming protocols (HLS, MPEG-DASH) to container formats (CMAF, MP4).
• Champion a culture of innovation and experimentation, where team members are encouraged to explore, test, and refine novel ideas, while balancing platform scale with product velocity.
• Establish a clear technical vision and direction for our media systems, while staying ahead of the curve in terms of emerging technologies.
• Navigate ambiguity with confidence, utilizing data-driven insights to guide the team towards successful outcomes.
• Work in close partnership with Product, Data, and ML teams to ensure effective leadership, alignment with broader organizational objectives, and maximum impact.

Qualifications:

• Bachelor’s or Master’s degree in Computer Science, Data Science, or a related quantitative field.
• 8+ years of industry experience, including 3+ years of engineering management experience, specifically leading complex, high-volume consumer systems. Experience managing cross-platform teams (Backend and Mobile/Client) is highly preferred.
• Proficiency in at least one programming language (Java, Go, Python).
• A strong background in video streaming technologies, CDN routing, and media ingestion. You should understand the intricacies of multi-part uploads, encoding schedulers, and adaptive bitrate streaming.
• Proven ability to balance immediate performance fixes (e.g., MP4 playback optimizations) with long-term architectural overhauls (e.g., media delivery at the edge, caching strategies).
• Experience defining and governing clear Ser
