About the Role

We are looking for a hands-on Web Scraping / Crawling Engineer with 3–5 years of experience in web scraping, browser automation, and scalable data extraction.

The ideal candidate should have strong experience working with dynamic and JavaScript-heavy websites, building reliable crawling workflows, handling crawling failures, and working with distributed processing systems.

This is a highly technical, hands-on role. You will be expected to design, develop, debug, optimize, and maintain web crawling and data extraction systems.

Responsibilities

• Design, develop, and maintain scalable web crawling and scraping systems for dynamic and JavaScript-heavy websites.
• Develop browser automation workflows using Playwright, Selenium, Puppeteer, or similar frameworks.
• Investigate and resolve crawling issues such as 403/429 responses, redirects, timeouts, rendering failures, session issues, and anti-bot challenges.
• Develop robust retry, fallback, and failure-handling mechanisms to improve crawler reliability.
• Work with cookies, sessions, browser contexts, headers, proxies, and related crawling mechanisms to maintain state and improve crawling reliability.
• Build and optimize concurrent and distributed scraping workflows using asynchronous processing, queues, and worker-based architectures.
• Design data pipelines covering URL processing, crawling, extraction, validation, transformation, and storage.
• Optimize crawler performance, including concurrency, browser lifecycle, resource utilization, timeouts, and request handling.
• Implement monitoring and observability for crawl success rates, failure types, latency, retries, and worker performance.
• Debug complex crawling problems and identify root causes rather than relying only on one-off fixes.
• Develop reusable crawling components and frameworks that can support multiple websites and use cases.
• Collaborate with data engineering, AI, backend, and product teams to deliver reliable and structured web data.
• Evaluate and adopt new web crawling, browser automation, and data extraction technologies where appropriate.

Required Skills

• 3–5 years of hands-on experience in web scraping, web crawling, browser automation, or web data engineering.
• Strong programming experience in Python. JavaScript/Node.js is a plus.
• Strong hands-on experience with Scrapy, Playwright, Selenium, Puppeteer, or similar browser automation frameworks.
• Strong understanding of HTTP, HTML, DOM, JavaScript rendering, redirects, cookies, sessions, headers, and browser contexts.
• Experience with browser fingerprinting, WAFs, and modern anti-bot mechanisms.
• Experience working with dynamic, JavaScript-heavy, and asynchronous websites.
• Good understanding of asynchronous programming, concurrency, and parallel processing.
• Experience with job queues, distributed workers, or message-based processing systems such as Redis, RabbitMQ, Kafka, Celery, or similar technologies.
• Understanding of retry mechanisms, error handling, idempotency, rate limiting, and backpressure in distributed systems.
• Hands-on experience with proxy management, session handling, and anti-bot challenges.
• Strong debugging and analytical skills, with the ability to investigate and resolve complex crawling failures.
• Experience working with SQL databases such as PostgreSQL or MySQL.
• Familiarity with Docker and cloud platforms such as AWS, GCP, or Azure is a plus.
• Strong hands-on engineering mindset rather than purely project or delivery management experience.
• Ability to independently debug, investigate, and solve difficult crawling problems.
• Strong understanding of how browsers, HTTP requests, sessions, and websites interact.
• Ability to design systems that are reliable, scalable, and fault tolerant.
• Good understanding of how to distribute and coordinate large-scale scraping workloads.
• Ability to identify the root cause of crawling failures and develop generalized, reusable solutions.
• Willingness to work across scraping, backend services, distributed processing, data pipelines, and infrastructure when required.
• Strong problem-solving skills and curiosity to understand how websites behave rather than relying solely on existing scraping tools.

Education

• Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field is preferred.
• Equivalent practical experience in software engineering or web scraping will also be considered.
