• Possess a Bachelor's Degree in Computer Science or related field, or equivalent professional experience
• Have a minimum of 5 years of experience in software engineering, with at least 3 years focused on full-stack development
• Have at least 2 years of hands-on experience building front-end applications with Vue.js, React, Lit, or similar frameworks
• Have at least 2 years of experience developing back-end services and microservices with Node.js
• Have a minimum of 1 year of experience designing and implementing APIs in GraphQL
• Have at least 1 year of experience building and deploying microservices in a production environment
• Have proven experience applying TDD to deliver high-quality, testable code
• Have hands-on experience with CI/CD pipelines and tools like Azure DevOps, Jenkins, or GitHub Actions
• Possess strong proficiency in JavaScript/TypeScript, HTML, and CSS
• Have knowledge of front-end performance optimization and accessibility standards (e.g., WCAG 2.2)
• Possess understanding of RESTful APIs, OpenAPI specifications, and GraphQL best practices
• Have familiarity with cloud platforms (e.g., Azure, GCP, AWS) and containerization tools (e.g., Docker, Kubernetes basics)
• Have experience interacting with databases, both SQL (e.g., PostgreSQL, SQL Server) and NoSQL (e.g., MondoDB, DynamoDB) varieties
• Have the ability to work independently, solve complex problems, and communicate effectively with technical and non-technical stakeholders

Responsibilities

• Independently design, develop, and deploy full-stack applications, including accessible UIs, GraphQL APIs, and Node.js-based microservices, ensuring seamless integration across all layers
• Build responsive and WCAG-compliant user interfaces, prioritizing accessibility for users of all abilities
• Optimize application performance (e.g., lazy loading, code splitting, query complexity analysis) and implement security best practices (e.g., OAuth2, JWT, input validation)
• Follow TDD principles to write comprehensive unit, integration, and end-to-end tests, ensuring high code quality and reliability using frameworks like Vitest, Jest, or Playwright
• Architect and implement scalable, domain-driven microservices with Node.js, adhering to modern best practices such as API-first design and cloud-native principles
• Design and develop efficient GraphQL services, including schema design, query optimization (e.g., batching, caching), and integration with front-end and back-end systems
• Deploy and manage applications on cloud platforms (e.g., Azure, GCP, or AWS), leveraging container technologies (e.g., Docker or Kubernetes) for scalability and resilience
• Partner with cross-functional Agile teams—including designers, product managers, and other engineers—to deliver impactful technical solutions that align with business goals
• Provide guidance on technical decisions, contribute to architectural discussions, and uphold development standards with minimal oversight
• Maintain clear, comprehensive technical documentation for APIs, microservices, and front-end components to support team collaboration and future maintenance

Preferred Qualifications

• Have familiarity with healthcare industry standards (e.g., HIPAA, FHIR) and building secure, compliant applications
• Have experience with Apollo Server, Federation, or optimizing GraphQL performance in large-scale systems
• Have hands-on experience with performance monitoring and optimization tools (e.g., Dynatrace, Prometheus, Grafana)
• Possess a Microsoft Azure Developer, AWS Certified Developer, or equivalent certification
• Have knowledge of micro-frontend architectures or modular design patterns for scalable UIs (e.g., Module Federation)
