Software Engineer, Node.js

Published: 25 March 2025

​

Description

We are looking for an experienced Node.js developer to create a web scraping script that logs into an energy provider’s system using user credentials and extracts relevant tariff information. The script should return the following details:

• Tariff Name
• Contract Start Date (if available)
• Contract End Date (if available)
• Tariff Rates applicable to the user’s agreement

​

Technical requirements

• The script should be implemented in Node.js.
• HTTP requests should be made using fetch, axios, or any other suitable library.
• If advanced protection mechanisms (e.g., CAPTCHA, JavaScript-based authentication) prevent direct HTTP requests, headless browsers (Puppeteer/Playwright) may be used as a fallback.
• The extracted data should be structured as a JSON object.
• Error handling should be implemented for login failures, session timeouts, and data extraction errors.
• The code should be modular and reusable.

​

Deliverables

• A well-documented Node.js script
• Instructions on how to run the script (including dependencies)
• Any necessary configuration files (e.g., .env for credentials)
• Example output JSON

​

Additional notes

• If the provider has API access for tariff retrieval, that approach is preferred over scraping.
• The script should be designed with scalability and maintainability in mind.

• Video call with Lead Engineer
• You complete the work
