• Coordinate knowledge transfer from incumbent vendors and own the team’s Knowledge Base (KB) quality.
• Mentor Java + DevOps engineers and L1 support engineers to drive technical excellence.
• Manage weekend release activities and coordination (several times per year).

About You:

• 5+ years of experience in application support or software engineering with heavy support responsibility.
• Prior experience as a Tech Lead or Senior Engineer in managed services is highly preferred.
• Ability to work independently and make critical decisions under pressure during production outages.
• Strong communication skills to simplify technical concepts for clients and stakeholders.
• Structured, detail-oriented, and well-organized approach to incident management.
• Fluent English is required for all tickets, escalations, and global communication.

Core Competencies & Technical Skills:

• Database Mastery: Oracle 11g and MS SQL Server (query writing, execution plan analysis, and stored procedures).
• Cloud & DevOps: Hands-on with AWS (Lambda, RDS, S3, CloudWatch) and CI/CD tools (GitLab, Docker, Kubernetes).
• Observability: Experience with Datadog for dashboards, alert configuration, and log correlation.
• ITSM Knowledge: Proficient in ServiceNow for incident, problem, and change management workflows.
