Java Full Stack Technical Lead
About the Role
We’re seeking a hands-on Java Full Stack Technical Lead who can architect, build, and scale API-first platforms and integrations. You’ll lead design and delivery of high-volume APIs, craft cloud-native microservices on AWS, and guide teams on best practices for reliability, security, and observability. This role blends deep back-end expertise (Java, Spring) with front-end fundamentals (React/TypeScript) to deliver end-to-end features and integration experiences.
*Please note, this role is not able to offer visa transfer or sponsorship now or in the future*
Key Responsibilities
Architecture & API Design
· Own end-to-end API architecture (REST/GraphQL), including resource modeling, error schemas, versioning strategy and contract testing.
· Design domain-aligned microservices (DDD), event-driven patterns (Kafka/SNS/SQS) and distributed workflows.
· Define integration patterns (webhooks, event streaming, async queues, batch, CDC) and BFF (Backend-for-Frontend) layers for client needs.
· Delivery & Engineering
· Build Java 17+ / Spring Boot services; implement JPA/Hibernate, Spring Security, WebFlux, and Resilience4j for reliability.
· Establish and enforce API standards (OpenAPI/Swagger), linting, and SDK generation where appropriate.
Cloud & DevOps (AWS)
· Architect, implement, and operate workloads on AWS:
· Compute: ECS/Fargate, EKS, Lambda
· Networking: VPC, ALB/NLB, PrivateLink, API Gateway, Route 53
· Data: RDS/Aurora, DynamoDB, ElastiCache/Redis, S3, OpenSearch
· Integration: SNS/SQS, EventBridge, Step Functions, Kinesis
· Security: IAM, KMS, Secrets Manager, WAF, Shield, Cognito/OIDC
· Build secure CI/CD pipelines (GitHub Actions/Azure DevOps/Jenkins), IaC with Terraform/CloudFormation, and implement blue/green or canary deployments with automated rollbacks.
· Implement observability: distributed tracing, structured logging, metrics and SLOs via CloudWatch/Prometheus/Grafana.
Leadership & Collaboration
· Mentor engineers, lead code/design reviews, and foster engineering excellence.
· Collaborate with Product, Architecture, and Security on roadmaps, discovery, and prioritization.
· Champion documentation: API specs, runbooks, postmortems, and playbooks.
Work Model
We believe hybrid work is the way forward as we strive to provide flexibility wherever possible. Based on this role’s business requirements, this is a hybrid position requiring 2-3 days a week in a client or Cognizant office in Plano, TX. Regardless of your working arrangement, we are here to support a healthy work-life balance though our various wellbeing programs.

· Strong with integration patterns (sync/async), API versioning, backwards compatibility, schema evolution, and contract testing (Pact/WireMock).
· Proficient with SQL (PostgreSQL/MySQL/Aurora) and at least one NoSQL (DynamoDB/DocumentDB); caching with Redis.
· Proficient in CI/CD, IaC (Terraform/CloudFormation), Docker, and container orchestration (ECS/EKS).
