As a Senior Site Reliability Developer (IC4), you will play a key role in ensuring the availability, scalability, and operational excellence of OCI's Japan Sovereign Cloud services. You will design and implement automation, drive service reliability improvements, lead complex incident investigations, and partner with development teams to improve operational readiness. You will own and prioritize an SRD operational improvement backlog based on shift feedback, incident reviews, alert quality reviews, and business reliability requirements.
