Senior Software Engineer – Data

About Mux

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.

We’re committed to building a healthy team that welcomes diverse backgrounds and experiences. We want people who care about our mission, are ready to grow, believe in our values (from Be Human to Turn Customers Into Fans), and want to improve the people around them.

You’ll join a tight-knit team with experience at places like Google, YouTube, Twitch, Reddit, Zencoder, Fastly, and more. Our founders previously started (and sold) Zencoder, an early leader in cloud video technology, and authored Video.js, the biggest HTML5 video player on the web. We organize Demuxed, the premiere conference for video engineers in the world.

We’re backed by top investors like Coatue, Accel, Andreessen Horowitz, and Y Combinator. You’ll get to work with amazing companies: hundreds of startups, plus Strava, Patreon, Vimeo, Robinhood, PBS, and Equinox. Customers, large and small, love working with us and love our team.

We are building something big together. We’d love to hear from you!
About the Role
As a Senior Software Engineer on the Mux Data team, you will play a key role in building Mux’s next-generation data products. Mux Data empowers developers to monitor and optimize end-to-end video playback experiences for millions of viewers worldwide.

You will lead and execute complex projects across our data stack and infrastructure, which collects and aggregates over a trillion requests each month. You will also help shape the technical direction of our data platform and product offerings, working 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, developing features that help customers optimize video experiences.
• Develop features as part of a full stack product team. Contribute to the full development cycle: technical design, development, testing, experimentation, analysis, launch, and on-call. You’ll review code and design docs, provide feedback on product specs, and take ownership of your code in production.
• Take accountability for planning and delivering projects, both as a hands-on contributor and architect, as well as a facilitator.
• Drive ideas and contribute to your team’s roadmap, collaborating closely with cross-functional stakeholders.
• Build and promote best practices within your team for availability, reliability, and production readiness.

Who You Are

• 4+ years of experience in backend or data engineering using Golang 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 data systems in a service-oriented architecture, with a solid understanding of best practices for fault tolerance, latency, and observability.
• A track record of writing high-quality, maintainable code across multiple services and team boundaries.
• Solid operational experience with data streaming technologies (e.g., Kafka), Kubernetes, monitoring tools (e.g., Grafana & Prometheus), and databases (e.g. Clickhouse, Redis).
• Strongly preferred: In-depth experience building and scaling data streaming applications.
• Experience with video playback telemetry and performance metrics (e.g., rebuffer rates, latency, etc.) is a plus. Experience with Elixir, React/Typescript a plus.
• Excellent communication, collaboration, and problem-solving skills.
