Anti-Bot Engineer

Anti-Bot Engineer, Search Api

We are looking for an engineer obsessed with breaking through anti‑bot systems such as Cloudflare, Akamai, Data Dome, and Perimeter

X. If you've spent hours analysing fingerprinting techniques, debugging TLS handshakes, and figuring out why your headless browser gets detected, this role is for you.

Search Api is a real‑time SERP API delivering structured data from 100+ search engines and sources, including Google Search, Google Shopping, Google Jobs, Bing, Baidu, You Tube, Amazon, and many more. We power production workloads for Fortune 500 companies and fast‑moving startups who need reliable search data at scale.

We’re a lean, profitable, bootstrapped team. No VC pressure, no bloat. Just engineers shipping real products to real customers.

• The hardest problems. Anti‑bot systems evolve constantly. You’ll be at the cutting edge of evasion techniques.
• Real impact. When you break through a protection, thousands of customers benefit immediately.
• Deep technical work. This isn’t surface‑level scraping. It’s fingerprinting, TLS, CDP internals, browser behaviour analysis.
• Fortune 500 customers. Our API powers production workloads, not just experiments.
• Bootstrapped and profitable. We answer to customers, not investors.

• Playwright, Puppeteer, raw CDP
• Ruby, Node.js, or Python for tooling
• Browser internals (Chromium, Firefox)
• Network analysis tools (Wireshark, Burp Suite, Proxyman)
• AWS infrastructure
• Ruby on Rails familiarity is a plus (we use it for internal tools)

We ship faster because we use AI tools aggressively. Cursor and Claude. But you own the output. If you can’t evaluate what AI produces, you’re not ready for this role.

• Research and implement anti‑bot evasion techniques.
• Reverse‑engineer bot detection systems. Understand how they work, then bypass them.
• Work with browser fingerprinting: canvas, WebGL, audio, fonts, navigator properties, and more.
• Debug TLS fingerprinting (JA3, JA4, HTTP/2 fingerprints).
• Optimize Playwright/Puppeteer configurations for stealth.
• Analyse network traffic to understand detection mechanisms.
• Build internal tools for testing and validating evasion techniques.
• Stay ahead of the latest developments in bot detection.
• Document findings and share knowledge with the team.

You define the work. We don’t have a task list for this role. You tell us what you’ll work on based on what’s broken, what’s getting detected, and where you see opportunities. This is how much control you’ll have.

• Cat and mouse game. What works today might not work tomorrow. You need to constantly adapt.
• Deep debugging. Sometimes you’ll spend days figuring out why a single request gets blocked.
• Ambiguity. Anti‑bot systems don’t publish their detection methods. You reverse‑engineer and experiment.
• Pressure. When a major protection changes and customers are affected, you need to fix it fast.
• Lonely expertise. Few people understand this domain deeply. You’ll often be figuring things out alone.

• Obsessed with evasion. You’ve spent your own time trying to bypass protections. You find it fun.
• Hacker mindset. You enjoy reverse‑engineering and figuring out how systems work.
• Deep technical skills. Browser internals, networking, fingerprinting. Not surface‑level knowledge.
• Persistent. You don’t give up when something doesn’t work. You try another approach.
• Great writer. You document your findings clearly so others can learn.
• Self‑directed. You don’t need someone to assign tasks. You find the next problem to solve.
• Fluently speaks English, written and spoken.
• BSc or higher in CS or equivalent technical field.

• Deep experience with Playwright, Puppeteer, or Selenium internals.
• Understanding of browser fingerprinting techniques and how to spoof them.
• Experience bypassing at least one major anti‑bot system (Cloudflare, Akamai, Data Dome, Perimeter
  
  X, etc.).
• Network traffic analysis (Wireshark, Burp Suite, mitmproxy, or similar).

• TLS fingerprinting experience (JA3, JA4, HTTP/2).
• WebRTC fingerprinting and evasion.
• Chromium or Firefox source code familiarity.
• Experience at scale…
