Team Lead - Cloud Engineer (Azure & Kubernetes)

Pracovní nabídka

We’re looking for a senior engineer who wants to lead a team while staying hands-on with cloud and Kubernetes.

You’ll lead a team of 9 engineers working on services that are part of the ESET XDR platform. As Team Lead, you’ll be responsible for the people in the team, including regular 1:1s, feedback, performance reviews, goals, career development and compensation.

Around 30% of your time will be focused on team leadership. The rest will be hands-on engineering work, mainly around Microsoft Azure, AKS, Kubernetes, Terraform and Helm.

You’ll help design and evolve the architecture of our production cloud environment. We currently run Kubernetes clusters across 5 production regions, and the environment is continuously evolving. You’ll work on scaling, performance, reliability, cost optimization, monitoring, logging and security, including addressing security findings.

You’ll work closely with other senior engineers, architects, Product Owners and Security. For new solutions, you’ll help shape the architecture, discuss the trade-offs with the team and work with Security on threat modelling and security requirements.
