• Define a pragmatic remediation plan with clear priorities, owners, and success metrics (SLIs / SLOs).
• Establish a delivery cadence (standups, checkpoints, and readouts) to drive remediation through to production.
• Demonstrate effectiveness via measurable outcomes (reduced MTTR, error budgets honored, latency / throughput targets met).

Core SRE Responsibilities

• Lead performance testing (load, stress, soak) using BlazeMeter / JMeter; analyze results and tune platforms (caching, thread / connection pools, GC, autoscaling, query / index tuning).

• Build / operate observability (Datadog, Splunk / ELK, CloudWatch / New Relic) : dashboards, alerts, traces, logs, and SLO / error-budget policy.
• Architect secure, scalable infrastructure on AWS (ECS, S3, Lambda, VPC) with IaC (Terraform); containerize / run services with Docker.
• Optimize / maintain CI / CD in Jenkins (gates for quality, security, and performance); integrate automated tests into delivery pipelines.
• Run SRE programs: on-call, incident response, post-mortems, and continuous improvement; partner with teams on Kafka / microservices best practices.

Key Skills & Qualifications

• 10+ years in SRE / Infrastructure Engineering (Java + UNIX / Linux background).
• Hands-on BlazeMeter / JMeter expertise and platform performance tuning.
• Proficient with Kafka, Terraform, Jenkins, Docker, AWS (ECS, S3, Lambda, VPC), and IaC patterns.
• Strong with Datadog / Splunk / ELK / CloudWatch / New Relic; builds usable dashboards and actionable alerts.
• Networking fundamentals (VPCs, load balancers, DNS, TLS, peering) and environment management at scale.
• Scripting / automation in Python and Bash.
