Senior / Staff Video Software Engineer

Mux is video for developers. Our mission is to democratize video by solving the hard problems developers face when building video: video encoding and streaming (Mux Video), video monitoring (Mux Data), and more. Video is a huge part of people's lives, and we want to help make it better.

As a Senior / Staff Video Software Engineer at Mux, you will play a key role in building Mux's next-generation Video products that power delightful user experiences for millions worldwide. You will lead and execute complex projects across our Video stack and infrastructure, handling hundreds of thousands of videos ingested and more than a billion encodes per month using our proprietary just-in-time transcoding architecture. You will also help chart the technical direction of our platform and product offerings and work closely with the rest of the engineering team to advance how we build software collaboratively.

What You'll Do:

• Work cross-functionally with product, customer success, and other engineering teams to execute on product and business strategy and build cutting-edge Video products that our customers will love.
• Contribute to the full development cycle: technical design, development, test, experimentation, analysis, launch & on-call. You'll review code and design docs, give feedback on product specs, and run your code.
• Take accountability for the planning and delivery of projects, both as a hands-on contributor and architect and as a facilitator.
• Bring ideas and directly influence your team's roadmap, collaborating closely with cross-functional stakeholders, especially regarding Video features and functionality.
• Build & promote best practices in your team for availability, reliability, and production readiness.

Who you are:

• 5+ years of experience in production Backend & Video Engineering using Golang, C, C++, or other similar languages, with a successful track record of contributing to sizable projects from start to finish with end-user impact.
• Expertise in building and operating distributed video systems in a service-oriented architecture, including best practices for fault tolerance, latency, and observability.
• A track record of writing high-quality, maintainable code across multiple services & team boundaries.
• Solid operational experience with Kubernetes, monitoring tools (we use Grafana & Prometheus), databases (we use CockroachDB, Clickhouse, & Redis) and data streaming technologies (we use Kafka).
• Strongly preferred: In-depth experience building integrated Video products using open-source libraries like ffmpeg or libav, and ideally, direct contributions to them. You also know what PSNR, VMAF & SSIM are and how to move those. Solid knowledge of different video codecs, encoding, profiles, and compatibility, and a track record of debugging, fixing & optimizing encoding-related issues end to end.
• Excellent communication, collaboration, and problem-solving skills.
