Description :

Role Overview :

We are seeking a Consultant/Lead Software Engineer with Java as the primary skill and AWS as secondary to architect and deliver scalable, secure, and resilient cloud-native platforms.

This is a hands-on technical role covering design, implementation, performance, security, and observability combined with technical mentorship, accountability for outcomes, and clear stakeholder communication.

Key Responsibilities :

- Architecture & Solution Design : Translate business and NFRs into robust service, data, and integration designs, document decisions (ADRs), define API contracts and versioning strategies.

- Build & Delivery : Implement Java/Spring Boot microservices and REST APIs, design event-driven integrations, ensure backward compatibility and operational readiness.

- Cloud Engineering (AWS) : Select and apply the right AWS services/patterns (serverless vs. containers) for scale, reliability, security, and cost efficiency.

- Quality Engineering : Establish test strategies (unit, integration, contract, performance), enable shift-left quality with CI quality gates and automated pipelines.

- Performance & Resilience : Profile JVM and databases, tune queries and memory, apply resilience patterns (circuit breakers, retries, bulkheads) and effective caching.

- Security & Compliance : Implement secure coding, OAuth2/JWT, secrets management, encryption, align to policy/regulatory requirements and support risk remediation.

- Observability & Operability : Implement logs/metrics/traces, define SLIs/SLOs, actionable alerts, dashboards, drive incident readiness and RCAs.

- Cost Optimization : Right-size resources, design efficient data access patterns, and apply autoscaling, lifecycle policies, and caching/CDN strategies.

- Stakeholder Communication : Communicate options, trade-offs, risks, and delivery plans clearly with Product, Architecture, Security, and SRE.

- Technical Mentorship : Mentor engineers via pairing, code/design reviews, and knowledge shares, contribute reusable libraries, templates, and IaC modules.

- Facilitate agile ceremonies : (stand-ups, backlog refinement, sprint planning, demos, retros) with a focus on technical outcomes, risk surfacing, and sprint goal clarity.

- Refine stories into actionable technical tasks : ensure Definition of Ready/Done, unambiguous acceptance criteria, testability, and accurate story point estimation.

Qualifications :

Must-Have Skills :

Java (Primary ) :

- Java / Java 8+

- Deep OOP and SOLID principles.

- Proficiency with Streams API, Optional, functional interfaces, lambda expressions.

- Multithreading & Concurrency : Thread pools, Future/Completable Future, synchronization, locks, concurrent collections.

Web & API :

- Design/implement RESTful APIs (idempotency, pagination, error models) .

- Rate limiting & API Gateway concepts, OpenAPI/Swagger documentation.

- Exposure to enterprise web servers (WebLogic/WebSphere) or embedded servers (Tomcat/Jetty).

Spring Framework :

- Spring Core (IoC/DI), Spring MVC, Spring Boot (auto-configuration, starter dependencies).

- Spring Security (JWT, OAuth2), Spring Batch, Spring AOP.

Data & Integration :

- Strong SQL (PostgreSQL/MySQL) : schema design, indexing, query tuning.

- Caching (Redis), messaging/eventing (Kafka/RabbitMQ), outbox/idempotency patterns.

Engineering Excellence :

- Build/CI/CD : Maven/Gradle, Git, Jenkins/GitHub Actions/Azure DevOps, trunk-based or GitFlow.

- Testing : JUnit 5, Mockito, Testcontainers, contract testing (Pact), performance testing (JMeter/Gatling).

- Observability : Structured logs, metrics, OpenTelemetry tracing, ELK/Prometheus/Grafana dashboards.

- Security : OWASP Top 10, dependency scanning, SBOM awareness.

AWS (Secondary ) :

- Core Services : Lambda, API Gateway, S3, DynamoDB, RDS/Aurora, EventBridge, SQS, SNS, ECS/Fargate, monitoring with CloudWatch/X-Ray, auditing with CloudTrail.

- Security & Networking : IAM (least privilege), KMS encryption, VPC (subnets, SGs/NACLs), Secrets Manager/Parameter Store, basic WAF.

- Infrastructure as Code : AWS CDK (TypeScript preferred) or Terraform/CloudFormation, environment promotion and GitOps-friendly workflows.

- Reliability & Cost : Autoscaling, throttling, DLQs, retries/backoff, cost-aware designs (right-sizing, storage tiers, capacity models for DynamoDB).

- Deployment Patterns : Blue/green, canary, feature flags, zero-downtime deployments.

Good to Have :

- Step Functions, Kinesis/MSK, ElastiCache, OpenSearch.

- Containers/orchestration with Docker and Kubernetes/EKS.

- API versioning strategies and consumer-driven contracts.

- Chaos testing, DR/backup planning, and multi-account landing-zone familiarity.

Soft Skills :

- High ownership and accountability for delivery quality, performance, and reliability.

- Clear stakeholder communication with options, trade-offs, and data-backed recommendations.

- Mentorship mindset, collaborative, pragmatic problem-solving and strong documentation
