Job Details

Strong experience designing and implementing cloud-native application architectures on AWS.
Hands-on expertise with AWS services including Lambda, Step Functions, API Gateway, SNS, SQS, EventBridge, ECS/EKS Fargate, and Amazon Bedrock.
Proven experience with both serverless and containerized application architectures.
Strong understanding of event-driven architectures and distributed systems, including patterns such as sagas, eventual consistency, circuit breakers, retries, and idempotency.
Experience designing contract-first APIs using API Gateway and OpenAPI 3.x, including API versioning and authentication.
Practical experience incorporating generative AI into production applications, particularly agents, RAG, Amazon Bedrock, guardrails, and evaluation approaches.
Solid understanding of application security and AWS IAM, including least-privilege principles and RBAC/ABAC.
Experience with operational observability, including CloudWatch or Datadog and SLI/SLO practices.
Experience with Infrastructure as Code, particularly Terraform, and modern CI/CD delivery practices.
Strong architectural thinking and the ability to balance scalability, resilience, performance, security, and cost.

Design and implement serverless and containerized applications on AWS using services such as Lambda, Step Functions, ECS, and EKS Fargate.
Architect solutions with a strong focus on resilience, concurrency, cost optimization, retries, and dead-letter queue (DLQ) strategies.
Design contract-first APIs using API Gateway and OpenAPI 3.x, incorporating appropriate versioning and authentication approaches.
Implement real-time communication channels, including technologies such as Server-Sent Events (SSE) and MCP.
Design event-driven architectures using SNS, SQS, and EventBridge, ensuring ordering, idempotency, reliability, and low latency.
Develop and integrate production-ready generative AI solutions, including AI agents, Amazon Bedrock, RAG architectures, guardrails, and quality evaluation.
Apply distributed-systems patterns such as sagas, eventual consistency, and circuit breakers to build robust enterprise applications.
Design and implement secure application architectures using IAM principles, least privilege, and RBAC/ABAC approaches.
Establish effective operational observability using tools such as CloudWatch and Datadog, supported by appropriate SLI/SLO practices.
Implement infrastructure and application delivery as code using Terraform and CI/CD pipelines.
