Head of SRE

About the Team

We handle tens of millions of customers each day playing our games which turns into quite the infrastructure challenge. We receive billions of requests, among API calls and RPCs, and we serve billions of queries in our databases as well. This means we process many terabytes of logs and other data. All the while our growth continues meaning these numbers aren’t stagnant and the challenges keep mounting. As we continue to grow, scale and reliability are evermore tantamount to the success of the company and support of our gamers.

The SRE team is one of our newer parts of this Infrastructure team. We have a core team in Sao Paulo but as we look to grow and scale we wanted to build out the team, both in terms of leadership but also geography.

About the Role

Our Irish office is looking for someone who wants autonomy for making game-changing changes to our infrastructure and who can deal with a really high scale and dedicated to the reliability of our end-to-end infrastructure. You will roll up your sleeves and dive into the issues that affect reliability be it on systems, software, process, and operational levels. You will be relentless in the search for how to best automate to free up time for our SREs and software engineers to focus on the next big challenges. But also for how best to playbook and create seamless processes for handling all sorts of challenges (cost & efficiency, migrations, integrations & rollouts, outages, etc).

As this is a management position for a team that doesn't exist yet, you will have full autonomy to build it. First and foremost will be to source, attract, and staff the local team as well as to help onboard and integrate them with the Sao Paulo SRE team and broader engineering organisation. You will need to be an experienced manager who has built out a team and know how to effectively staff a team given limited resources and creative planning. Second, you will need to design and implement the model for SRE engagement working with engineering leadership on assimilation and support. This will then open up to developing a set of shared processes and playbooks by which not only SRE org but all of engineering org will need to think about and design for scale, reliability, and performance.
