Job summary

SearchApi is seeking an engineer obsessively focused on breaking through anti-bot systems. You’ll tackle fingerprinting, TLS handshakes, and headless-browser evasion at scale, collaborating on real-time SERP data delivery.

The role emphasizes deep technical work, with ownership over how you approach challenges and the impact you create for clients. The position offers a fully remote setup, equity, and profit sharing, plus fast-paced learning and opportunities to work on the hardest problems in

Qualifications

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, DataDome, PerimeterX, etc.).
Network traffic analysis with Wireshark, Burp Suite, mitmproxy, or similar.

Responsibilities

Research and implement anti-bot evasion techniques.
Reverse engineer bot detection systems and understand how they work, then bypass them.
Work with browser fingerprinting: canvas, WebGL, audio, fonts, navigator properties, and more.
Debug TLS and protocol fingerprinting (JA3, JA4, HTTP/2, HTTP/3 over QUIC, header order and casing).
Optimize Playwright/Puppeteer configurations for stealth.
Analyze network traffic to understand detection mechanisms.
Build internal tools for testing and validating evasion techniques.
Stay ahead of the latest developments in bot detection.

Job description

We are looking for an engineer obsessed with breaking through anti‑bot systems. Cloudflare, Akamai, DataDome, PerimeterX. If you've spent hours analyzing fingerprinting techniques, debugging TLS handshakes, and figuring out why your headless browser gets detected, this role is for you.

About SearchApi

SearchApi is a real‑time SERP API delivering structured data from over 100 search engines and sources, including Google Search, Google Shopping, Google Jobs, Bing, Baidu, YouTube, 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.

Why Join Us

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 behavior analysis.
Fortune 500 customers. Our API powers production workloads, not just experiments.
Bootstrapped and profitable. We answer to customers, not investors.

We are searching for grinders who take ownership and move fast. You'll work on the hardest technical challenges in web scraping.

Tech Stack

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 use Cursor, Claude, ChatGPT, GitHub, and Slack daily. We ship multiple times a day with CI/CD.

You Control AI, AI Doesn't Control You

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.

What You'll Do

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 and protocol fingerprinting (JA3, JA4, HTTP/2, HTTP/3 over QUIC, header order and casing), and push the QUIC frontier where most detection and most scrapers haven't caught up yet.
Optimize Playwright/Puppeteer configurations for stealth.
Analyze 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.

The Hard Parts

This role is not for everyone. Here's what makes it hard:

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.

If you want clear specifications and predictable work, this isn't for you.

About You

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.
Fluent in English, written and spoken.
BSc or higher in CS or equivalent technical field.

Required Experience

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, DataDome, PerimeterX, etc.).
Network traffic analysis (Wireshark, Burp Suite, mitmproxy, or similar).

We're Especially Looking For

TLS and protocol fingerprinting experience (JA3, JA4, HTTP/2, HTTP/3 over QUIC).
WebRTC fingerprinting and evasion.
Chromium or Firefox source code familiarity.
Experience at scale handling millions of requests.
Running headless browsers stably at scale in containers.
Contributions to open‑source evasion tools.

What We Look For

Tell us about the hardest anti‑bot system you've bypassed. What was the detection method? How did you figure it out? What was your solution? We want specifics, not generics.
