Description

Own end-to-end development of enterprise applications, from Angular frontend components to Node.js microservices and Oracle data layers. You will design scalable architectures, enforce engineering standards, and mentor junior developers.

This role is on-site.

Responsibilities

  • Build and maintain Angular 15+ applications using TypeScript, implementing lazy loading, reactive forms, and NgRx state management.
  • Architect scalable Node.js microservices and RESTful APIs with NestJS, ensuring validation, error handling, and versioning.
  • Develop and optimize complex Oracle SQL queries, stored procedures, and PL/SQL packages for high-performance data access.
  • Manage API testing via Postman and Newman CLI, integrating automated regression suites into CI/CD pipelines.
  • Participate in Scrum ceremonies, maintain Jira boards, and conduct code reviews to uphold engineering standards.

Required Skills

  • 7–10 years full-stack experience in enterprise or government environments.
  • Angular 12+ with deep knowledge of components, services, RxJS, and NgRx.
  • Strong TypeScript proficiency: generics, decorators, async/await, and strict null checks.
  • Node.js expertise with NestJS or Express.js, REST API design, and event-driven patterns.
  • Oracle database skills: SQL, PL/SQL, stored procedures, query optimization, and execution plans.
  • Experience with CI/CD integration, Git workflows (GitFlow or trunk-based), and Postman/Newman.
  • Bachelor's degree in Computer Science, Software Engineering, or equivalent.

Preferred Skills

  • Cloud platform experience (AWS, Azure, or GCP) and containerization with Docker/Kubernetes.
  • Message queuing experience with RabbitMQ, Kafka, or Oracle Advanced Queuing.
