Role Summary

OnTrac is seeking an experienced Senior Full-Stack Cloud Engineer to support our digital platform initiatives. In this role, you will design, build, test, and deploy modern full-stack application features spanning a React frontend, a Node.js REST API, and a PostgreSQL database. Working alongside internal engineering resources and partner teams, you will also manage cloud deployments, infrastructure automation, and CI/CD pipelines on Google Cloud Platform (GCP) using Terraform and Docker.

Requirements & Qualifications

• Google Cloud Certification: Active certification as a GCP Associate Cloud Engineer or Professional Cloud Developer (or equivalent demonstrated depth on Google Cloud).
• Containerization: Hands-on experience with Docker for containerizing Node.js applications and managing containerized runtime environments.
• Infrastructure as Code (IaC): Solid proficiency writing and managing Terraform scripts to provision GCP infrastructure.
• CI/CD Expertise: Proven ability to configure and maintain automated build, test, and deployment pipelines using Google Cloud Build or GitHub Actions.
• Full-Stack Proficiency:
  • Frontend: Strong experience building modern, responsive UI components in React directly from Figma designs.
  • Backend: Expertise designing, building, and securing RESTful APIs with Node.js.
  • Database: Deep knowledge of PostgreSQL, including relational data modeling, writing SQL queries, and managing schema migration scripts.
• Testing Beyond Unit Level: Hands-on experience implementing integration and end-to-end (E2E) testing strategies (e.g., Cypress, Playwright, Supertest) alongside standard unit testing.

Key Responsibilities

Application Engineering & Interface Development

• Design and implement full-stack application features across the React frontend, Node.js backend, and PostgreSQL schema.
• Translate design team mockups from Figma into clean, responsive, and reusable React components and views.
• Build and maintain the REST API layer handling communication between frontend and backend services.

Database Design & Schema Management

• Design and evolve the PostgreSQL relational data model to support new application capabilities.
• Author SQL queries and write schema migration scripts to execute database updates safely across environments.

Testing & Quality Assurance

• Write unit tests for new and modified code as a standard part of the software development lifecycle.
• Build and maintain integration and end-to-end (E2E) tests to validate user journeys and system interactions beyond the unit level.

GCP Infrastructure & DevOps

• Provision, deploy, and configure application components on Google Cloud Platform—including runtime services, managed PostgreSQL (Cloud SQL), and Cloud Storage—using Terraform.
• Set up, optimize, and maintain CI/CD pipelines covering automated builds, test execution, container image generation, and deployments.

Technical Alignment & Documentation

• Participate in collaborative working sessions with OnTrac project teams and external partner stakeholders (such as SADA) to define requirements and establish technical approaches.
• Author and maintain comprehensive technical documentation, including system architecture, API contracts (OpenAPI/Swagger), and data models.
