Sr. Systems Engineer (Angular-NodeJS FullStack Developer)

SAIC is looking for a dedicated Full-Stack Software Engineer to help build, support and migrate a cloud-based Web Dashboard application that processes healthcare EDI transactions. The ideal candidate will design and maintain RESTful APIs, support an Angular-based frontend, and collaborate with backend engineers to ensure reliable data delivery.

Responsibilities:

• Design, build, and maintain RESTful APIs in Java and/or Node.js that retrieve, transform, and serve EDI healthcare records
• Integrate with internal platform APIs, EDI processing pipelines, and data services to deliver live and historical EDI transaction data reliably and performantly
• Support and contribute to an Angular-based dashboard frontend — consuming APIs, building or maintaining components, and ensuring data is surfaced accurately to business and clinical users
• Collaborate with backend C#/.NET and AWS data engineers to define clean API contracts and ensure reliable data delivery across services
• Write clean, testable, well-documented code and participate actively in code review
• Perform unit and integration testing across backend services and API layers
• Support deployment, monitoring, and performance of backend services in production on AWS
• Apply and promote best software engineering practices within an agile framework
• Use Git and GitHub for version control, branching, pull requests, and collaborative development

Requirements:

• Bachelor's or master's degree in computer science, Engineering, or a related technical discipline required; equivalent practical experience considered
• 8 years of software development experience with a strong backend focus (Java and/or Node.js)
• Experience designing and consuming RESTful APIs in healthcare or enterprise environments
• Proven experience building backend services that serve structured EDI or healthcare data to frontend applications
• Some hands-on Angular experience — able to integrate APIs and contribute to frontend components
• Strong backend development experience in Java and JavaScript/TypeScript/Node.js — API design, data transformation, error handling, and performance
• Experience with Angular or another Modern front-end framework
• Proven ability to build RESTful APIs that consume and transform structured data (XML, JSON)
• Experience working with EDI data formats
• Familiarity with web document submission processes a plus
• Working knowledge of Angular — components, services, API integration; frontend development is secondary but real
• Hands-on Cloud (Azure/AWS) experience — API Gateway, Lambda, S3, CloudWatch, or related services
• Proficient with Git and GitHub — branching strategies, pull requests, collaborative workflows
• Experience with unit and integration testing frameworks (JUnit, Jest, or equivalent)
• Strong communication skills — able to work with stakeholders and cross-functional engineers to define and refine API requirements
• Experience with agile methodologies (Scrum, Kanban) and JIRA
• Ability to work independently and as part of a distributed team
• Strong attention to detail — especially around data accuracy and fidelity for healthcare records
• Ability to conduct code reviews and provide constructive feedback
• US Citizenship required with the ability to obtain and maintain a Public Trust clearance
• Familiarity with healthcare payer/PBM systems, clearinghouses, or pharmacy operations
• Experience with VA systems, ARS workflows, or 275 claim attachment transactions
• Knowledge of HIPAA compliance requirements in API and web application development
• Familiarity with accessibility standards (Section 508 / WCAG 2.1) for government-facing applications
• Experience with containerization (Docker, ECS, EKS)
• Familiarity with C#/.NET backend services for cross-team integration touchpoints
