Nest JS Developer

Simelabs - An Astek Company 8590718392 hr@simelabs.com Company Profile Nest JS Developer ROLE OVERVIEW Aspire is seeking a Full stack developer specializing in NestJS to build and maintain the API / integration layer for a government citizen-facing eServices portal. The platform follows a threetier modernization pattern: a modern Angular front end for citizens, a NestJS middleware layer for orchestration and security, and a CA Gen (Cool:Gen) legacy core that remains the system of record for citizen data and business rules. This role sits at the centre of that architecture — translating citizen requests from Angular into secure, validated calls against the legacy core, without exposing that core directly to the public internet. KEY RESPONSIBILITIES • Design, build and maintain RESTful (and where applicable GraphQL) APIs in NestJS that serve the Angular citizen portal. • Implement authentication, authorization, and citizen identity verification (JWT/OAuth2/SSO), including session and token management. • Orchestrate and translate requests into the CA Gen legacy backend via SOAP/REST wrappers, message queues, or direct database access, depending on the exposure method agreed with the legacy team. • Apply request validation, DTOs, and business logic that the legacy core does not natively enforce. • Own API security for the integration layer: input validation, rate limiting, audit logging, and adherence to OWASP practices — this layer is the primary trust boundary between the public portal and citizen data. Aspire Infotech | 120 Queen Rania Street, P.O. Box 3150, Amman 11181, Jordan | T +962 6 516 3046 | info@aspire.jo | aspire.jo • Write and maintain automated unit and integration tests; participate in code reviews. • Document APIs using OpenAPI/Swagger for consumption by the Angular team and other integrators. • Collaborate closely with the Angular frontend team, the CA Gen/legacy backend team, and infrastructure/DevOps to deliver end-to-end features. • Support performance tuning, monitoring, logging, and production issue triage across the integration layer. • Contribute to technical documentation and knowledge transfer for a government client environment with formal audit and compliance requirements. REQUIRED SKILLS & EXPERIENCE • 4–5 years of overall software development experience, including at least 2–3 years of handson NestJS/Node.js development in production environments. • Strong command of TypeScript and modern JavaScript (ES6+). • Working familiarity with Angular, to support smooth collaboration with the frontend team • Solid understanding of REST API design principles; working knowledge of GraphQL is an advantage. • Experience integrating modern applications with legacy or monolithic backend systems (SOAP services, message queues, mainframe/midrange systems, or flat-file interfaces). • Hands-on experience with authentication/authorization standards: JWT, OAuth2, SSO. • Proficiency with relational databases (MongoDB, IBM DB2) • Practical knowledge of API security best practices (OWASP Top 10, rate limiting, input sanitization, audit logging). • Proficient with Git and collaborative development workflows; exposure to CI/CD pipelines. • Experience writing automated tests with Jest or an equivalent framework. • Comfortable working directly with government or public-sector clients where compliance, data residency, and audit requirements are heightened. NICE TO HAVE • Prior exposure to CA Gen / Cool:Gen or other 4GL/legacy modernization environments. • Prior experience on eGovernment or citizen-services digital transformation programmes. QUALIFICATIONS • Bachelor's degree in Computer Science, Software Engineering, or a related field.
