About the role

As a Software Engineer on the Billing & Collections platforms, you contribute directly to the systems that keep the company financially healthy. Your work helps ensure customers receive accurate bills, can make seamless payments, and experience smooth interactions throughout their billing journey. By building reliable, scalable, and high quality software, you help maintain consistent cashflow, reduce revenue leakage, and support strong customer trust. This role gives you the opportunity to make a measurable impact on mission critical business operations while growing your engineering skills in a complex, high visibility domain.

What you’ll be doing

Front-End Engineering & Solution Implementation

Support the implementation of UI technical solutions across billing applications.

Work with backend/API teams to resolve integration issues and deliver smooth cross-system functionality.

Contribute to UI components, design systems, and reusable front-end frameworks.

Architecture & Technical Decision Support

Participate in evaluating technology options (Angular/React, Node, Webpack, NPM, etc.).

Support front-end architecture discussions to balance short‑term delivery with long‑term platform modernization (micro-frontends, containerization, cloud readiness).

UI Design & Development

Implement screens, workflows, dashboards, and customer‑facing modules aligned with BT security, accessibility, and performance standards.

Convert UX wireframes into pixel-perfect, responsive UI components.

Code Review & Engineering Best Practices

Participate in UI code reviews, ensuring adherence to coding standards, performance tuning, and maintainability.

Keep updated with modern UI trends, frameworks, and industry best practices.

Technical Specifications & Documentation

Support the design of UI technical specifications for features and enhancements.

Contribute to estimation, feasibility analysis, effort breakdown, and documentation.

Coding, Testing & Quality Delivery

Write clean, modular, testable code using Angular/TypeScript, HTML5, SCSS, Bootstrap, and Jasmine/Karma.

Perform unit testing, integration testing, and participate in SIT/UAT cycles.

Integration & Compatibility

Integrate UI with backend systems (APIs, Spring MVC controllers, JSP outputs).

Troubleshoot UI rendering issues, browser compatibility problems, and platform inconsistencies.

Production Support & Defect Resolution

Monitor and resolve UI defects across SIT/UAT/Production environments.

Support real-time troubleshooting for issues like CDN failures, policy changes, Zscaler/VPN migration impacts, etc.

Tooling, Automation & CI/CD

Support CI/CD pipelines for UI builds, artifact deployment, test automation, and NPM dependency management.

Contribute to implementation of linting, code formatting, quality gates, and automated builds.

Technical Roadmap Contribution

Support UI modernization initiatives such as Angular upgrades, dependency cleanup, migration to micro-frontends, or containerization (Podman/Docker).

Assist with design and execution of long-term front-end transformation roadmaps.

Engineering & Operational Excellence

Participate in performance monitoring, logging, and observability improvements (ELK Stack, Prometheus, Grafana).

Help track engineering metrics like Core Web Vitals, accessibility rating, build times, and test coverage.

Process Improvement & Collaboration

Contribute to improving team processes, sprint workflows, coding guidelines, and documentation quality.

Collaborate closely with cross-functional teams like ASG, TI, QA, Product, and partner teams
