  • Deploy, manage, and optimize containerized applications on Kubernetes, OpenShift, EKS, GKE, or AKS.
  • Design and implement scalable solutions on AWS, Google Cloud Platform (GCP), and Microsoft Azure.
  • Optimize application performance, scalability, reliability, and resiliency in distributed environments.
  • Design and optimize database solutions using Oracle, PostgreSQL, Cassandra, and Redis.

  • Implement security best practices including OAuth 2.0, OIDC, RBAC, Keycloak, HashiCorp Vault, and secure API development.
  • Monitor application health using Prometheus, Grafana, OpenTelemetry, and ELK Stack.
  • Participate in architecture discussions, code reviews, mentoring junior engineers, and driving engineering best practices.
  • Collaborate with product owners, architects, QA, and DevOps teams to deliver high-quality software solutions.
Required Qualifications
  • Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
  • 10+ years of software development experience with strong expertise in Java (Java 8–21).
  • Extensive experience with Spring Boot, Spring Cloud, Microservices, and distributed system design.
  • Hands-on experience with Apache Kafka, REST APIs, gRPC, and event-driven architectures.
  • Strong experience with Docker, Kubernetes, OpenShift, and container orchestration platforms.
  • Experience deploying and managing applications on AWS, GCP, or Azure.
  • Strong knowledge of relational and NoSQL databases including Oracle, PostgreSQL, Cassandra, and Redis.
  • Experience implementing CI/CD pipelines using Jenkins, GitHub Actions, ArgoCD, and build tools such as Maven.
  • Strong understanding of software architecture, design patterns, performance tuning, and scalability.
  • Experience with Agile/Scrum development methodologies and version control systems such as Git.
Preferred Qualifications
  • Experience with Quarkus, Akka, Scala, or Python.
  • Knowledge of Terraform, Helm, and Infrastructure-as-Code practices.
  • Experience with OpenTelemetry, distributed tracing, and observability platforms.
  • Familiarity with Vertex AI, cloud-native AI services, or modern data platforms.
  • Excellent communication, leadership, mentoring, and problem-solving skills.
