Site Reliability Engineer (SRE) – Kubernetes / Observability / Java

Role Summary

We are looking for an experienced Site Reliability Engineer (SRE) with a strong background in Kubernetes, production support, observability, SQL, and Java-based applications. The role will focus on ensuring the availability, reliability, scalability, and performance of business-critical production systems.

The ideal candidate will combine strong application troubleshooting skills with SRE and DevOps practices, using Datadog and/or Prometheus for monitoring and observability and Kubernetes for managing containerized workloads. A strong understanding of Java applications and relational databases/SQL is essential for diagnosing issues across application, infrastructure, and data layers.

Key Responsibilities

• Own the reliability, availability, and operational health of business-critical production applications and services.
• Provide L2/L3 production support, including incident triage, troubleshooting, resolution, and stakeholder communication.
• Monitor and support applications deployed on Kubernetes, including pods, deployments, services, ingress, resource utilization, scaling, and cluster-related issues.
• Implement and maintain application and infrastructure monitoring using Datadog, Prometheus, dashboards, metrics, logs, and alerts.
• Define and monitor SLIs, SLOs, SLAs, error budgets, and service-health indicators for critical applications.
• Troubleshoot production issues across Java applications, APIs, microservices, Kubernetes, databases, and infrastructure.
• Analyze Java application logs, exceptions, JVM performance, memory utilization, thread behavior, and garbage collection to identify performance and reliability issues.
• Use SQL to investigate production incidents, validate data, identify data-related issues, and perform application-level troubleshooting.
• Participate in incident management, major incident calls, root-cause analysis (RCA), and post-incident reviews.
• Identify recurring production issues and drive permanent remediation through automation and engineering improvements.
• Build and enhance monitoring dashboards, alerting mechanisms, and operational runbooks to improve early detection and reduce recovery time.
• Drive improvements in MTTR, availability, performance, capacity, and production stability.
• Automate repetitive operational activities using scripting and appropriate DevOps/SRE tooling.
• Support application releases, production deployments, rollback activities, and post-deployment validation.
• Work closely with Development, Infrastructure, DevOps, Database, Security, and Business teams to ensure production readiness.
• Participate in on-call and production support rotations as required.

Required Skills & Experience

• 5+ years of overall IT experience , with significant experience in SRE, Production Support, Application Support, or DevOps roles.
• Strong hands-on experience with Kubernetes and containerized applications.
• Experience with Datadog and/or Prometheus for monitoring, alerting, metrics, and observability.
• Strong experience supporting Java/J2EE or Java-based microservices applications in production.
• Good understanding of JVM troubleshooting, application logs, memory, threads, garbage collection, and performance issues.
• Strong SQL skills with experience troubleshooting relational databases and application data issues.
• Experience managing P1/P2 production incidents, including incident coordination, RCA, and problem management.
• Good understanding of REST APIs, microservices, distributed systems, and application integration patterns.
• Experience with Linux/Unix environments and shell scripting.
• Understanding of CI/CD pipelines, release management, and deployment practices.
• Strong analytical and troubleshooting skills with the ability to diagnose issues across multiple technology layers.

Preferred Skills

• Experience with cloud platforms such as AWS/ Azure.
• Familiarity with Docker, Helm, GitLab/GitHub Actions, or similar DevOps tooling.
• Experience with centralized logging platforms such as ELK/OpenSearch or Splunk.
• Exposure to Infrastructure as Code tools such as Ansible/Terraform.
• Understanding of load balancing, networking, DNS, certificates, and application security.
• Experience implementing automation to reduce manual operational effort and production toil.
• Familiarity with ITIL processes including Incident, Problem, and Change Management.
• Production Reliability: Ability to maintain highly available and resilient production services.
• Observability: Strong understanding of metrics, logs, traces, dashboards, and actionable alerting.
• Incident Management: Ability to rapidly diagnose and restore services during critical incidents.
• Problem Management: Strong RCA skills with focus on permanent remediation rather than repeated tactical fixes.
• Automation: Ability to identify and automate repetitive production-support activities.
• Performance Engineering: Ability to identify bottlenecks across Java applications, Kubernetes, and databases.
• Stakeholder Management: Ability to communicate clearly during incidents and work effectively across engineering and business teams.

Success Measures
