• Integrate AI-driven automation with observability platforms, incident management systems, and operational workflows, incorporating appropriate human oversight and security controls.
• Troubleshoot Java-based applications, REST APIs, microservices, and cloud-native workloads deployed on OpenShift, Kubernetes, or equivalent platforms.
• Collaborate with development teams on application defects, CI/CD pipelines, deployment automation, and production readiness.

Collaboration & Continuous Improvement

• Collaborate with Product, Engineering, SRE, Cybersecurity, and Delivery teams to ensure reliable and secure production operations.
• Participate in technical retrospectives, post-implementation reviews, and continuous service improvement initiatives.
• Support incident, problem, change, and release management processes aligned with ITSM practices.
• Contribute to operational knowledge repositories, automation frameworks, and engineering best practices.
• Identify opportunities to adopt emerging AI technologies, Agentic AI capabilities, and automation solutions to improve engineering productivity and operational efficiency.

Minimum Qualifications

• Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field, or equivalent practical experience.
• 3+ years of experience in application support, production engineering, site reliability engineering, or software engineering.
• Strong hands-on experience troubleshooting enterprise applications, resolving production incidents, and performing root cause analysis.
• Proficiency in programming or scripting languages such as Java, Python, Ruby, Perl, or Unix Shell.
• Working knowledge of Java-based applications, Spring frameworks, REST APIs, JSON, and microservices architectures.
• Familiarity with web technologies such as JavaScript, HTML5, and Node.js.
• Hands-on experience with observability and application performance monitoring tools such as Splunk, ELK Stack, Dynatrace, or equivalent platforms.
• Experience designing, developing, and implementing operational automation using Python, Shell scripting, Ansible, APIs, or orchestration frameworks.
• Working knowledge of AIOps concepts, including intelligent alerting, anomaly detection, event correlation, and automated incident management.
• Experience automating production support activities, including monitoring, diagnostics, incident triage, and remediation workflows.
• Experience supporting applications on OpenShift, Kubernetes, or other cloud platforms.
• Familiarity with CI/CD tools such as Jenkins and GitHub.
• Understanding of ITSM concepts, Agile methodologies, and tools such as Jira.
• Strong analytical, troubleshooting, communication, and collaboration skills.
• Ability to work effectively in a fast-paced, business-critical production environment.

Preferred Qualifications

• Experience supporting Identity and Access Management (IAM), authentication, authorization, or cybersecurity applications.
• Knowledge of OAuth 2.0, OpenID Connect (OIDC), JSON Web Tokens (JWT), and API security concepts.
• Experience supporting highly available, large-scale distributed applications and microservices.
• Understanding of SRE principles, including Service Level Indicators (SLIs), Service Level Objectives (SLOs), and reliability metrics.
• Experience with advanced observability technologies such as Grafana, Prometheus, OpenTelemetry, and distributed tracing.
