<p><p><b>Description : </b></p><br/><p>Senior DevOps Engineer (AWS) India</p><br/><p><b>Overview : </b></p><br/><p>As a senior DevOps Engineer, you will own the AWS infrastructure and DevOps toolchain for a high-scale ad serving system composed of asynchronous Java microservices (Akka framework).
Targets include <50ms response time and up to 5M concurrent users with 99.99% uptime.</p><br/><p><b>Responsibilities : </b></p><br/><p>- Design & stand up AWS environments end-to-end (landing zone, VPCs, networking, security, automation).</p><br/><p>- Build immutable infrastructure and CI/CD for Java microservices (Maven/Gradle) including blue/green & canary releases and automated rollbacks.</p><br/><p>- Implement observability : metrics, logs, traces, SLOs/SLIs, alerting, on-call runbooks.</p><br/><p>- Engineer reliability & performance : autoscaling, caching layers, multi-AZ/region DR, capacity planning to support 5M+ concurrent users and p95/p99 latency goals.</p><br/><p>- Establish security-by-design : IAM least privilege, KMS/Secrets Manager, WAF/Shield, image/signing policies, CIS benchmarks.</p><br/><p>- Partner with EY developers & Performance Test Engineer to tune JVM/Akka, thread pools, GC, and infra limits based on load-testing feedback.</p><br/><p>- Champion cost governance and tagging; produce dashboards and weekly reports.</p><br/><p><b>Tech youll use (you dont need every single one, but you know most) : </b></p><br/><p>- AWS : EKS/ECS, EC2, ALB/NLB, API Gateway/Lambda, S3/CloudFront, DynamoDB/ElastiCache (Redis), Aurora/RDS, MSK/Kinesis, OpenSearch, Route 53, VPC, NAT/GW, WAF/Shield, CloudWatch/X-Ray, IAM, KMS, Secrets Manager.</p><br/><p>- IaC & CI/CD : Terraform/CloudFormation, Helm, Argo CD or Flux, GitHub Actions/Jenkins/GitLab CI, Docker.</p><br/><p>- Observability : CloudWatch, OpenTelemetry, Prometheus/Grafana, log pipelines.</p><br/><p>- Languages/Build : Bash/Python for automation; familiarity with Java build/release workflows.</p><br/><p><b>What makes you a great fit : </b></p><br/><p>- 35+ years total experience; Senior/Manager-level depth in AWS platform engineering for high-throughput, low-latency services.</p><br/><p>- Proven ownership of production systems at 10k1M+ concurrent users (or comparable high RPS) with 99.9x SLOs.</p><br/><p>- Hands-on with Akka/Java microservice delivery pipelines (nice if youve tuned JVM, GC, Akka dispatchers).</p><br/><p>- Strong grounding in scaling patterns (event-driven, async IO, caching, backpressure, rate limiting) and resilience(circuit breakers, retries, chaos).</p><br/><p>- Excellent collaboration, documentation, and stakeholder communication.</p><br/><p><b>Logistics : </b></p><br/><p>- Location : Remote (prefer India candidates)</p><br/><p>- Schedule : Must join US morning calls (Eastern Time) as needed.</p><br/><p>- Start : 1-3 weeks from offer.</p><br/></p> (ref:hirist.tech)
