Java software developer Jobs in Durham, NC

Job#: 3024583

Job Description:

Position Title: Senior Backend Developer/Java Application Lead

Location: Hybrid in Durham

Duration: 12-month Contract-Hire

Team: Histology Pod – Connect Program (Corporate IT)

About the Program

• The Connect program is a multi‑year modernization initiative migrating legacy COBOL-based LIMS systems to a modern Java + Spring Boot + Angular + AWS stack. The system spans 35 medical disciplines, with Histology and Cytology as key modules. This role joins the Histology pod, supporting both a backfill and new feature expansion as additional lab workflows come online.
• You’ll build in a brownfield environment: extending and evolving a complex, high-dependency system where disciplined sequencing and architecture choices matter.

Role Overview

• This is a blended role with ~70% hands-on development and ~30% architectural/design ownership. The team values lead-level behaviors—technical decision-making, mentoring, and cross-functional influence—more than prior “lead” titles. You’ll have support to grow into full ownership as you learn the domain and system.

What You’ll Do

• Design, build, and deploy RESTful microservices with Spring Boot on AWS, following enterprise standards and secure-by-default practices.
• Provide technical leadership: guide design reviews, solution patterns, and tradeoff decisions in a brownfield system.
• Collaborate directly with business stakeholders via the liaison team to understand lab workflows and translate them into scalable, reliable services.
• Promote engineering excellence: code quality, testing discipline, observability, secure coding, and CI/CD best practices.
• Mentor engineers on design choices, code reviews, and modern Java practices.
• Champion AI-augmented development (, Cursor, CodeWhisperer, Cloud Code) to improve productivity and delivery speed.
• Participate in Agile ceremonies (daily standups, sprint planning/reviews) and contribute to continuous improvement.

Must-Have Qualifications

• 10–12+ years backend engineering experience building enterprise-grade systems.
• Strong Java (11–21) fundamentals; modern Java features and idioms preferred.
• Spring Boot and REST API development experience (required).
• AWS (critical must-have): 3+ years hands-on experience (prefer 5+) with services such as Lambda, S3, SQS/SNS, API Gateway, ECS/EKS/EC2, IAM. AWS depth matters more than generic “cloud.”
• Brownfield systems experience: evolving existing platforms, respecting constraints, and sequencing changes to avoid system-level dependency conflicts.
• Solid understanding of application security (, Spring Security, OAuth , OIDC) and secure design.
• Proficiency with datastores: SQL (, Postgres/Oracle) and at least familiarity with NoSQL (, DynamoDB).
• CI/CD with Git-based workflows and build tools (Jenkins/GitHub Actions, Maven/Gradle, SonarQube).
• Strong communication skills and the ability to work directly with business stakeholders on requirements and workflows.
• Openness to AI tooling in day-to-day development; able to discuss what you’ve tried and how you use it responsibly and effectively.

Nice-to-Have

• Messaging/eventing: Kafka, RabbitMQ, SQS/SNS (used in the environment; not a deal-breaker).
• Containerization & platforms: Docker, Kubernetes/OpenShift.
• Observability: AppDynamics/Dynatrace/Datadog; logs via Splunk or ELK/OpenSearch.
• Testing discipline: TDD with JUnit 5, Mockito; strong coverage habits.
• Infrastructure as Code: Terraform/CloudFormation.
• Experience in healthcare/LIMS domain.
• Familiarity with agentic coding practices, prompt engineering, and LLM concepts.

Team & Ways of Working

• Team: 7 onshore devs + 5 offshore, with plans to grow by 2–3 later this year.
• Highly collaborative; engineers partner closely with business through a liaison team.
• Expectation to participate in daily standups, sprint ceremonies, and requirements discussions.

Interview Process

• Round 1 – Virtual (45 min): Conversation with hiring manager focused on architecture instincts, AWS/Java depth, brownfield problem-solving, and AI tooling usage.
• Round 2 – Onsite (panel): Scenario-based and architectural reasoning; discussion of prior experiences. Light or no coding—the emphasis is on design, tradeoffs, and how you work with AI tools.

Education

• Bachelor’s degree in computer science or equivalent practical experience.

Why This Role

• Help modernize mission-critical lab systems that directly impact patient outcomes.
• Work in a modern stack on AWS with meaningful ownership and growth into broader lead responsibilities.
• Join a collaborative team that values pragmatic architecture, craftsmanship, and AI-augmented productivity.
