👋 Hi there! At Flipflow, we're looking for an Anti-Bot Engineer to join our Technology team and play a key role in how our platform collects data at scale from the open web — reliably, efficiently and undetected. This is a very hands-on, full-time engineering role, deep in the trenches of web scraping infrastructure and anti-detection systems. You will work at the intersection of Engineering, Research and Operations, ensuring our crawlers can access any public website, bypass bot-detection systems and deliver high-quality data to our customers. 🌍 About Flipflow & Our Mission Flipflow is a Retail Market Intelligence & Digital Shelf Analytics SaaS platform, currently scaling internationally after strong growth in Spain and Latin America. Since our launch in 2021, our mission has been clear: To give brands, manufacturers and retailers a real-time, actionable and reliable cockpit and AI copilot to understand their products, competitors and markets — enabling better business decisions. Retail is undergoing one of the biggest transformations in its history: markets are global, competition is tougher than ever, and margins increasingly depend on execution and data. At Flipflow, we believe real-time competitive intelligence is no longer optional — it's a strategic advantage. 🎯 Your Challenge & Impact We collect data from hundreds of retailers and marketplaces worldwide — each with different anti-bot protections, page structures and access challenges. As an Anti-Bot Engineer, your mission is to ensure that: • Customer accounts receive complete, accurate data by keeping crawlers running at full capacity, • Anti-bot and anti-scraping protections are systematically analyzed, understood and bypassed, • Our scraping infrastructure evolves to stay ahead of detection systems, reduce block rates and increase data coverage 🧑🏻💻 What will you do? Reverse Engineering & Analysis • Actively research new anti-bot techniques, evasion strategies and detection trends. You’ll stay ahead of an industry that evolves weekly. 👤 Your Profile Must-have: • 4+ years of experience in Anti-Bot Engineering, Web Scraping Engineering, Offensive Security Research, Penetration Testing (web-focused) or similar roles., • Strong experience with browser automation and stealth/anti-detection techniques., • Solid knowledge of HTTP internals (HTTP/1.1, HTTP/2, HTTP/3) and TLS mechanics (JA3/JA4 fingerprints, cipher suites)., • Ability to deobfuscate and reverse-engineer JavaScript detection scripts., • Knowledge of TCP/IP fingerprinting (p0f, MTU/MSS) and proxy/VPN detection techniques., • Experience with browser internals — WebGL rendering, canvas fingerprinting, Audio API identification., • Bug bounty, CTF experience or contributions to open-source anti-detect/scraping tools., • Familiarity with Go for high-performance HTTP clients. 🎓 Education Bachelor's degree in: • Computer Science (Grado en Ingeniería Informática) — focused on software engineering, systems, networks and security., • Cybersecurity or related specialization — with strong emphasis on web security and adversarial techniques., • Or equivalent professional experience in related technical fields. 🧠 Core Competencies At Flipflow, we value engineers who combine technical skills with operational impact. We're looking for someone with: • Ownership mindset, reliability and a strong bias towards action, • Adversarial thinking — you understand how detection systems work from the inside and enjoy finding creative ways around them, • Practical, execution-focused mindset — shipping beats theorizing, • Comfort operating in ambiguous, fast-changing environments where protections evolve weekly, • Curiosity and continuous learning — you read security blogs, follow anti-bot research and stay up to date with the latest evasion techniques, • Solid communication and collaboration skills 💥 What We Offer • 💶 Compensation: Competitive salary aligned with a engineering role, • 🚀 Real impact: Your work directly enables the entire platform’s data collection, • 🧠 Accelerated learning: Exposure to cutting-edge anti-bot systems, browser internals and adversarial security. You will work alongside amazing Senior teammates building complex software., • 💪 Flipflow culture: High standards, autonomy, frequent feedback and strong teamwork, • ⌚ Flexibility: Hybrid model (2 days remote / 3 onsite), • 🏖️ Location: Offices in La Marina, Valencia, within the Lanzadera ecosystem, • If you're excited about understanding how the web works at its deepest level and outsmarting the systems designed to stop you, we'd love to meet you.
