About the Team

Slack is looking for an engineering leader for our Demand/Traffic Engineering team which enables fast and reliable delivery of Slack to our 12M+ (and growing fast!) globally distributed daily active users. We are responsible for traffic management both at the Edge and within our cloud infrastructure, working to drive up reliability and drive down latency. We partner closely with SRE and application developers, enabling them to focus on implementing business logic instead of worrying about how to get traffic in and out of their services.

Slack already has a mature and stable infrastructure but we are taking everything to the next level by implementing even more intelligent components that utilize real-time performance metrics to make traffic routing decisions and further optimize our customer experience. Our team consists of hybrid systems, software, and network engineers who take ownership of large scale infrastructure while continuously improving reliability and building automation.  

In summary, we look after the ingress/egress load-balancing tier for Slacks global traffic.

The scale and complexity of Slack’s network is a unique opportunity. Combined with the explosive rate of growth we expect this to be one of the world’s best traffic engineering teams, tackling tough problems on a global scale. This team headquarters at Slack’s HQ in SF with the addition of our Demand/Traffic team in Dublin, Ireland. You will be close partners with the Engineering Manager in Dublin and manage this San Francisco-based team.

Slack has a positive, diverse, and supportive culture — we look for people who are curious, inventive, and work to be a little better every single day. In our work together we aim to be smart, humble, hardworking and, above all, collaborative. If this sounds like a good fit for you, why not say hello?

Your responsibilities include:

  • Support the Demand/Traffic team with servant leadership and strategy development
  • Recruit and retain the technical talent required to solve our toughest design and support problems

  • You are able to weigh several and often conflicting constraints and make rapid decisions in a dynamic and quickly-growing company.
  • You are highly organized. With many people doing many things in a fast-paced company, strong organizational skills—both for yourself and for the team—will be required.


  • You are not expected to deliver code, but you should possess enough technical experience in Demand or Traffic automation and tooling to recognize the important decisions your team faces and give meaningful advice.
  • You have several years experience serving in an engineering management role.
  • You possess extraordinary written and verbal communication skills.
