About the role
We’re seeking a hands-on Senior 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/TypeScript) to deliver end-to-end features and integration experiences.
In this role, you will:
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: Hybrid.

What you need to have to be considered:
· 6+ 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/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).
· 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 + TypeScript (or Angular), including state mgmt (Redux/RTK/React Query), routing, and component design.
· Excellent communication, stakeholder management, and mentoring skills.
*Please note, this role cannot offer visa transfer or sponsorship now or in the future*
These will help you stand out:
· Hold a bachelor’s degree in computer science or related field.
· Event-driven architectures with EventBridge/Kinesis, CDC (Debezium), and saga patterns (Step Functions/temporal-like orchestration).
· GraphQL (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).
