• API Design, Architecture & Integration
• AWS (ECS/EKS/Lambda, API Gateway, ALB, Route 53, Cloud Front), Docker, Terraform/Cloud Formation, Jenkins, Cloud Watch, Grafana/Prometheus
• Commercial Banking knowledge

• We’re seeking a hands‑on Senior/Lead Java FSD 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/Type Script) to deliver end‑to‑end features and integration experiences.

• Own end‑to‑end API architecture (REST/Graph
  
  QL), 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.

• Build Java 17+ / Spring Boot services; implement JPA/Hibernate, Spring Security, Web Flux, and Resilience4j for reliability.
• Develop front‑end features using React + Type Script, focusing on performance, accessibility, and maintainable components.
• Establish and enforce API standards (OpenAPI/Swagger), linting, and SDK generation where appropriate.

• Architect, implement, and operate workloads on AWS:
  • Compute: ECS/Fargate, EKS, Lambda
  • Networking: VPC, ALB/NLB, Private Link, API Gateway, Route 53
  • Data: RDS/Aurora, Dynamo
    
    DB, Elasti Cache/Redis, S3, Open Search
  • Integration: SNS/SQS, Event Bridge, Step Functions, Kinesis
  • Security: IAM, KMS, Secrets Manager, WAF, Shield, Cognito/OIDC
  • Build secure CI/CD pipelines (Git Hub Actions/Azure Dev Ops/Jenkins), IaC with Terraform/Cloud Formation, and implement blue/green or canary deployments with automated rollbacks.
  • Implement observability: distributed tracing, structured logging, metrics and SLOs via Cloud Watch/Prometheus/Grafana.

• 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.

• 14+ years professional software engineering experience; 3+ years architecting cloud‑native services on AWS.
• Expert in Java 11+/17, Spring Boot, REST, JSON, OpenAPI, and asynchronous messaging (SNS/SQS/Kafka).
• Strong with integration patterns (sync/async), API versioning, backwards compatibility, schema evolution, and contract testing (Pact/Wire Mock).
• Proficient with SQL (Postgre
  
  SQL/MySQL/Aurora) and at least one No
  
  SQL (Dynamo
  
  DB/Document
  
  DB); caching with Redis.
• Proficient in CI/CD, IaC (Terraform/Cloud Formation), Docker, and container orchestration (ECS/EKS).
• Solid observability (logs, metrics, traces) and performance tuning (JVM, DB, API latency, throughput).
• Security‑first mindset: IAM, KMS, Secrets Manager, WAF, CORS, CSP, input validation.
• Front‑end capability with React + Type Script (or Angular), including state mgmt (Redux/RTK/React Query), routing, and component design.

• Back End:
  Java 17, Spring Boot, Spring Cloud, Web Flux, JPA/Hibernate, Resilience4j
• APIs: REST, Graph
  
  QL, OpenAPI/Swagger, Pact
• Messaging & Events:
  Kafka/SNS/SQS, Event Bridge, Kinesis
• Data:
  Postgre
  
  SQL/Aurora, Dynamo
  
  DB, Redis, S3, Open Search

  React 18, Type Script, Vite/Webpack, Jest, Cypress/Playwright
• Dev Ops & Cloud: AWS (ECS/EKS/Lambda, API Gateway, ALB, Route 53, Cloud Front), Docker, Terraform/Cloud Formation, Jenkins, Cloud Watch, Grafana/Prometheus

• Event‑driven architectures with Event Bridge/Kinesis, CDC (Debezium), and saga patterns (Step Functions/temporal‑like orchestration).
• Graph
  
  QL (Apollo/Federation) and BFF patterns; API monetization and developer portal experience.
• Multi‑account AWS strategy, landing zones, network segmentation, and service mesh (App Mesh/Istio).
• Kubernetes (EKS), Helm, service autoscaling, pod disruption budgets, and cost optimization (Graviton/Spot).
• Experience in regulated environments (PCI, SOC 2, HIPAA) and data privacy (PII, GDPR).
