Freelance Junior Java Developer Jobs in Tennessee

Job Title: Senior Full-Stack Engineer (Java & Angular)
Role Overview
We are seeking a highly analytical and technically versatile Senior Full-Stack Engineer to drive the design, development, and evolution of our enterprise information systems. In this mid-to-senior level seat, you will act as a core technical anchor, moving seamlessly between hands-on feature development and high-level applications systems analysis.
You will collaborate directly with business stakeholders and systems analysts to translate diverse requirements into scalable technical specifications, design data-verification methods, and build automated deployment pipelines. This role is ideal for a seasoned developer who possesses a high level of technical leadership-someone who can optimize system performance, guide less-experienced programmers, and ensure absolute operational uptime across business-critical platforms.

• API Integration: Engineer, secure, and integrate robust RESTful APIs to facilitate seamless cross-platform data exchanges.
• Performance Tuning: Devise and modify system application procedures to optimize functional requirements including database capacity, processing times, and server response speeds.
Technical Leadership & Systems Analysis
• Requirement Translation: Partner directly with business units and systems analysts to interpret complex operational requirements and synthesize them into precise technical architecture documents.
• Project Ownership: Provide technical leadership on assigned discovery efforts and agile project phases; coordinate task assignments and verify code delivery results for cross-functional sprint teams.
• Team Mentorship: Provide ongoing technical guidance, code review support, and practical training to junior and less-experienced developers on the team.
• Quality Assurance: Design and execute rigorous software/system test plans, ensuring modern data verification methods are built into standard development procedures.
DevOps & Platform Reliability
• Pipeline Automation: Leverage Azure DevOps to manage source control, configure CI/CD pipelines, and maintain automated build/release workflows.
• Incident Response: Respond proactively to system failures and performance anomalies, implementing immediate diagnostic measures to minimize platform downtime and permanently eliminate the recurrence of underlying bugs.
Qualifications & Requirements
Minimum Qualifications
• Education: Bachelor's degree in Computer Science, Information Systems, or a related technical field (or an equivalent combination of verified professional technical experience).
• Experience Baseline: 5 to 7 years of professional experience in systems analysis, application development methodologies, and enterprise-level programming.
• Full-Stack Stack Demands:
oProven hands-on development track record with Java (JDK 8+) and Angular (v18+).
oStrong experience writing and optimization queries/stored procedures within Microsoft SQL Server.
oSolid familiarity with Azure DevOps infrastructure, source control, and automated CI/CD pipelines.

Preferred & Soft Skills
• Previous experience or technical familiarity working within the Health Insurance, Payer, or Healthcare Informatics industries is highly preferred.
• Exceptional communication skills with a proven ability to translate highly technical or abstract engineering concepts into clear, meaningful insights for non-technical business partners.
