Description

As an Engineering Manager, you enable your team to do their best work: approachable, a good listener, and a strong facilitator of ideas and knowledge. You bring your own ideas for improving the architecture and extending what our systems can do.

This is a hands-on leadership role. We want a manager who is also a strong engineer, someone who acts as technical lead, dives into the code and architecture when it matters, and sets direction by example.

THE ADS BACKEND TEAM

The team owns In-house Server-Side Ad Insertion (SSAI) solution: the whole ad pipeline, from deciding which ads to show to tracking every impression, built as a suite of services serving viewers at scale. These are business-critical services with a direct revenue impact, and we collaborate closely with our sister teams (Ingest & Storage, Streaming & CDN, Playback) and commercial and ad operations stakeholders.

We’re about to take SSAI to the next level: a major re-architecture. It’s the team’s flagship challenge ahead, and one we want this hire to help lead from the front.

WHAT YOU’LL DO

  • Lead the Ads Backend team, organizationally and technically
  • Own the technical vision and architecture of our SSAI platform, with the senior developers
  • Contribute hands-on as technical lead: review designs, raise the bar by example, and step into critical code when needed
  • Own the end-to-end development process and operational excellence for revenue-impacting services
  • Help shape the technical direction of Zattoo’s broader video platform, with the other video teams and our Principal Engineers
  • Drive cross-team initiatives spanning across multiple video teams.
  • Represent the team to stakeholders.
  • Directly manage 2 – 4 engineers and lead hiring
  • Grow, develop, and retain engineering talent

Requirements

  • 5+ years leading engineering teams
  • Strong, current hands-on engineering: you can design, build, and review production code and act as technical lead
  • Proficient in C++/Go
  • Experience building highly available services and APIs that scale
  • Experience with distributed systems, event-driven architectures and message queues (e.g. Kafka), and non-relational databases (e.g. Scylla)
  • Testing is a fundamental part of how you build software
  • Experience with advertising technology platforms, ad serving, and dynamic ad insertion (DAI/SSAI)
  • Broad experience across the video pipeline (ingest, transcoding, packaging, DRM, streaming, playback)
