automation of our platform and delivery processes. The focus is on building, improving, and
operating services through code and automation — supporting consistent deployments and stable
environments, while working closely with development teams in alignment with Tekton’s technical

assigned systems, and has the proactivity to identify and resolve issues before they become
problems.
