troubleshoot sync failures, schema drift, and performance issues; coordinate with source system owners on connector changes.Support and extend pipelines: manage job scheduling, run monitoring, model dependencies, and test coverage; work with data practitioners on performance optimization.Operate and harden our dev platform: manage user access, environment variables, secrets, deployment configurations, and platform upgrades.Administer Okta SSO integrations and auth0 across the platform; manage application assignments, SCIM provisioning, and authentication policies.Build and maintain CI/CD pipelines for infrastructure and application code; enforce automated testing, security scanning, and deployment gates.Author and maintain Dockerfiles and container images;
