 We're Hiring: Web Scraping Support Engineer (Remote)

Hello everyone! Massive is looking for a Web Scraping Support Engineer to join our fully remote team. If you dream in selectors, wake up parsing HTML, and genuinely enjoy helping people solve gnarly data extraction problems — this one's for you.

 What is Massive?
Massive is an infrastructure company powering data-driven innovation at scale. We operate a global proxy network, build managed APIs for search engines (SERP), and Web Unblocking API to bypass anti-bot measures for large-scale data collection and processing.

 Why This Role Is Different
Most support roles are reactive. This one isn't. You're the person customers trust when their scraping pipeline breaks at 2 AM, when a target site changes its structure overnight, when nothing works and nobody knows why. You don't just answer tickets — you solve problems that other engineers can't.

 Who We're Looking For
 

• Troubleshoots in Their Sleep: Broken selectors, anti-bot walls, rotating proxies, CAPTCHAs, headless browser quirks — you've seen it all and you fix it before your coffee gets cold
• AI is your best friend - you know how to leverage AI to be 10X faster and more productive
• Customer-Obsessed & Likable: You're the person customers ask for by name. You explain complex concepts in plain language and people genuinely enjoy working with you
• Can Scrape Anything, Anywhere: SPAs, paginated APIs, rate-limited endpoints, geo-restricted content — if it's on the web, you know how to extract it
• Consumes Data for Breakfast: You think in JSON, dream in XPath, and get excited about a well-structured dataset
• Relentlessly Organized: Your support board is pristine. Every ticket triaged, every follow-up tracked, every edge case documented. Nothing slips through — ever
• Curious Builder: When you notice the same issue three times, you don't just fix it — you automate the solution so it never comes back

 What You'll Be Doing
 

• Own the support board end-to-end with the support team — triage, prioritize, resolve, and follow up on every ticket
• Debug complex web scraping issues across proxy configurations, browser automation, and API integrations
• Help customers build, optimize, and fix their scraping pipelines
• Reproduce issues, identify root causes, and escalate bugs with full context to engineering
• Write documentation and guides that reduce repeat tickets

 Bonus Points
 

• Experience with Puppeteer, Playwright, Selenium or similar browser automation
• Hands-on with proxy networks and IP rotation strategies
• Familiarity with anti-bot systems (Cloudflare, Akamai, PerimeterX, DataDome)
• Working knowledge of Python, Node.js, or scripting languages for data extraction
• no satisfaction until all the work is done and then some

 Ready to Scrape the Future With Us?
Skip the generic resume. Show us something real — a scraper you built, a gnarly problem you debugged, a support process you transformed. We care about what you can do, not where you went to school.
If you read this and thought "finally, someone gets it" — trust that feeling. Apply now.
