• Support event-driven and data-integration solutions;
• Provide shared observability: dashboards, alerting and tracing standards;
• Embed security and compliance controls into platform defaults (secrets, vulnerabilities, certificates);
• Improve developer experience and platform resilience through runbooks, capacity management and automation that reduces operational toil;
• Track adoption, reliability and delivery outcomes, evolving the platform based on team feedback.

• Clear communication in English and experience working with international, cross-functional teams;
• Experience building an internal developer platform, service catalogue or self-service workflow (highly valued);
