Senior Backend Engineer / Tech Lead Memphis, TN OR Charlotte NC Onsite No H1B NO OPT  Need 13 Years of Experience    Key Responsibilities Design & implement REST APIs that maintain backward compatibility while evolving the entitlements domain model Orchestrate complex business workflows across multiple external systems (APIGEE, Interpose SOAP passthrough, Azure services) Own integration boundaries with downstream systems, including error handling, retry logic, idempotency, and response translation Build and maintain data persistence layers using Spring Data JPA / Hibernate against Azure SQL, with careful attention to transaction semantics and audit trails Implement caching strategies using Redis/Redisson for performance-critical paths Write production-grade tests that verify behavior, not just coverage—unit, service, and resource-layer tests Design and maintain Helm charts for Kubernetes deployments across multiple environments Implement CI/CD pipelines and deployment automation using modern DevOps practices Manage containerization with Docker, optimize images, and ensure security best practices Investigate and resolve production incidents using Dynatrace, DQL queries, and log analysis Document design decisions in architecture records and implementation plans; maintain alignment between code and documentation Mentor junior engineers on domain knowledge, testing practices, and architectural patterns specific to this system Required Technical Skills Core Java & Spring Java 21 with modern language features (records, sealed classes, pattern matching)

experience a plus) WebClient for async HTTP integrations with resilience patterns Experience with circuit breakers, retries, and timeouts (Resilience4j or equivalent) Understanding of idempotency and request deduplication in distributed systems Data & Persistence Azure SQL and relational schema design Spring Data JPA / Hibernate with complex mappings, composite keys, and cascading behavior Ability to reason about query performance, N+1 problems, and connection pooling Experience with database migrations and schema evolution Caching & Performance Redis and Redisson for distributed caching Cache invalidation strategies and TTL management Performance profiling and optimization Testing & Quality Writing unit, service, and integration tests that verify behavior Test-driven development (TDD) practices Checkstyle and code quality enforcement Familiarity with JUnit 5, Mockito, and MockWebServer DevOps & Infrastructure Kubernetes / AKS cluster management and deployment strategies Helm charts design, templating, and values management across environments Docker containerization, image optimization, and security scanning CI/CD pipelines (GitLab CI, GitHub Actions, or equivalent) Infrastructure-as-Code (IaC) principles and tools Azure services: Key Vault, SQL Database, Container Registry, managed identity mTLS and certificate-based authentication in Kubernetes Deployment automation, blue-green deployments, and rollback strategies Pod security policies, network policies, and RBAC in Kubernetes Observability & Operations Dynatrace for APM, log analysis, and trace investigation DQL (Dynatrace Query Language) for custom metrics and dashboards Understanding of SLOs, error rates, and latency analysis Ability to read and interpret production logs without exposing PII Health checks, readiness probes, and liveness probes in Kubernetes Metrics collection and monitoring strategy Cloud & Infrastructure Azure services: Key Vault, SQL Database, Container Registry, managed identity Kubernetes / AKS deployment concepts, scaling, and resource management Docker containerization and image management Container registries and image scanning Network configuration and service mesh concepts (optional but valued) Preferred Qualifications 10+ years of backend software engineering in Java/Spring 3+ years of DevOps, SRE, or infrastructure engineering experience Experience with banking or financial services domain (profiles, accounts, entitlements, audit) Familiarity with APIGEE API gateway or similar Hands-on experience with Helm charts in production environments Experience with Kubernetes in production (AKS, EKS, or GKE) Knowledge of GitOps practices and tools (ArgoCD, Flux) Experience with Databricks for audit reporting or analytics Knowledge of PowerShell for operational scripting Contributions to open-source projects or published technical writing Experience with incident response and RCA (root cause analysis) documentation

Redis, Redisson HTTP Client Spring WebClient Integrations APIGEE, Interpose SOAP, Azure Key Vault Observability Dynatrace, DQL, structured logging Testing JUnit 5, Mockito, MockWebServer Code Quality Checkstyle, Spotless, SonarQube Container Docker, Kubernetes/AKS Infrastructure Helm, Azure Container Registry CI/CD GitLab CI / GitHub Actions Audit Databricks, event-driven outbound workflows Code Quality & Standards You'll be expected to: Follow surgical, minimal-change principles when modifying code Preserve existing API contracts and status codes unless explicitly changing behavior Write focused tests that cover changed behavior, not just line coverage Maintain security standards: never log secrets, PII, or raw SOAP bodies Document design decisions in architecture records for major changes Participate in code review with attention to integration boundaries and transaction semantics Ensure Helm charts are maintainable, well-documented, and follow Kubernetes best practices Implement deployment automation with proper validation and rollback strategies       Looking forward to work with you !!   Riya  | Manager – Talent Acquisition United IT Solutions Inc | | Email:
