Java Technical Lead

TalentOla; Charlotte (NC); On-site; USD 120,000 - 150,000; Full time

Job summary

TalentOla is seeking a senior backend engineer in North Carolina to design and implement REST APIs, orchestrate complex workflows, and own integration boundaries across Azure and external systems. You will build robust data persistence layers with JPA/Hibernate, implement caching with Redis, and drive CI/CD, Docker, and Kubernetes initiatives.

Ideal candidates have Java 21, Spring Boot 3.5.4, and strong testing, DevOps, and observability skills.

Qualifications

• Strong Java and Spring backend experience with API design.
• Experience with Kubernetes, Helm, and CI/CD pipelines.
• Familiarity with caching, data persistence, and distributed systems.
• Excellent communication and mentoring abilities.

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 attention to transaction semantics and audit trails.
• Implement caching strategies using Redis/Redisson for performance-critical paths.
• Write production-grade tests that verify behavior—unit, service, and resource-layer tests.
• Design and maintain Helm charts for Kubernetes deployments across 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.

• 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
