Senior Python Scraping / Anti-Bot Engineer (EU Applicants Only)

Senior Technical Customer Success Engineer

ZenRows

ZENROWS  |  REMOTE (EU HOURS)  |  FULL-TIME   ABOUT ZENROWS Born in the Basque Country and built for the world, ZenRows is one of the fastest-growing data infrastructure startups in Europe. We work 100% remotely and hire the best people regardless of where they are. Founded in 2021, we started as a scraping API for developers. In 2026, we are evolving into something bigger: the data collection infrastructure layer for the AI era. Thousands of companies across e-commerce, finance, real estate, and AI rely on ZenRows to power their data pipelines. Now, we're building for the next generation of users: workflow builders, AI engineers, and business teams who don't write code but need data to flow reliably through their systems. We're looking for a Senior Technical Customer Success Engineer to own how ZenRows' customers integrate, succeed, and grow. Could that be you? THE ROLE Our customers are technical and they know it. When something breaks, they want it fixed, not filed. When they're evaluating us, they want someone on the call who actually understands their stack. This role is for someone who can get into the weeds of a broken integration and walk out of an enterprise sales call having helped close it. You'll own the technical relationship with our customers from day one: onboarding, escalations, account health, and the internal tooling that stops CS from becoming a bottleneck. CS at ZenRows is still being shaped. You're not walking into a playbook, you're writing it. DAY TO DAY, YOU'LL BE * The main technical point of contact for our customers across chat, Slack, calls, and escalations * Onboarding enterprise customers hands-on, writing integration samples, debugging their code, and running POCs * Joining sales calls as the technical voice and helping close deals * Keeping a close eye on account health and getting ahead of problems before customers feel them * Reproducing and fixing integration issues yourself, testing the API, writing samples, and digging through OpenSearch logs * Building internal automation that removes the repetitive stuff: API tests, triage workflows, reports, and sales-call prep * Writing guides, runbooks, and post-mortems that people actually refer back to * Giving product real evidence on bugs, friction points, and gaps and pushing for fixes * Creating regular reports for the team to help the company move forward. WHAT WE'RE LOOKING FOR * You've spent 5+ years in technical CS, Solutions Engineering, or Developer Support at a developer-first SaaS where customers expect real answers, not ticket numbers * You write working Python or JavaScript, can read a customer's code and spot what's wrong. Not an engineer, but close enough to be useful * DevTools is second nature. You have a good understanding of HTTP, DNS, TLS, proxies. You've built something with AI that actually saved you time. A workflow, a script, an integration. Not a prompt. Something that runs. * You're equally at home running a technical POC, reviewing account health, and jumping on a call with a VP of Engineering * You adjust naturally to who you're talking to, direct and technical with developers, clear and calm with decision-makers * You make the people around you better without being asked. You share what you know, pick up what needs doing, and set a standard others follow * You've worked with data-driven CS teams and want to be the person who brings that rigor to a team that's still defining what success looks like. * Strong written and spoken English (C1 level or above) BONUS POINTS IF YOU HAVE * Hands-on experience with scraping, anti-bot systems, proxies, or headless browsers (Puppeteer, Playwright, Selenium, mitmproxy) * You've hired, onboarded, or interviewed teammates before * Startup background. You know how to move without a safety net * Worked with CS tools like Intercom, Zendesk, Hubspot, Amplitude, Notion, Stripe, Typeform, Metabase, or similars * Has worked with technical buyers or developer personas HOW YOU'LL GROW WITH US YOUR SUCCESS IN 1 MONTH * Up to speed on the product, stack, and customer base. * Handling EU chat coverage almost autonomously. Escalating only where it is genuinely needed.  * Shadowing sales calls and co-running POCs alongside the team. * First small automation or internal improvement shipped. YOUR SUCCESS IN 3 MONTHS * Fully owns EU coverage. Chat, Slack support channels, escalations, account follow-ups. * Running technical pre-sales independently. Joining calls, scoping POCs, closing technical objections without backup. * Multiple internal automations shipped that meaningfully reduce repetitive work (tests, reports, triage, sales prep) * Actively contributing to docs and internal runbooks. * Pushing product feedback upstream with evidence: bugs, friction points, feature gaps. YOUR SUCCESS IN 6 MONTHS * Co-owns how the CS function operates with the existing teammate. Process, tooling, knowledge management, account health monitoring, … visibly better than when they joined. * Active in hiring: interviewing candidates, scoring, owning a stage of the process. * Trusted technical voice on enterprise accounts and strategic deals. * Recognized internally as a senior operator across CS, Sales, and Engineering. * The automation you’ve built is compounding. The team does more with less than it did on day one.  THIS ROLE ISN'T FOR EVERYONE * We're ~20 people competing against companies 10x our size. There's nowhere to hide, but why would we want to?  * Fully remote means more documentation and async discipline than most places. If you hate writing things down, that'll be a problem. * Feedback here is direct and frequent. Strong opinions are normal. If you want a quiet life, look elsewhere. * We're moving fast and things change. If you need stable processes and predictability, this will frustrate you. WHY PEOPLE LOVE IT HERE * You get to build something, not maintain it. CS is yours to shape from the ground up. * No micromanagement. You're trusted to make calls and own the outcome. * The co-founders are accessible and straight with you. What you do gets noticed. * Genuinely fun team. Remote doesn't mean disconnected, we invest in that. PERKS AND BENEFITS * 100% remote: work wherever you like, as long as EU hours are covered * Salary based on what you're worth, not what you were paid before * Pick your own equipment * Learning & Development budget * Annual team kick-off in a new location each year * Regular Barcelona meetups * Deel benefits: VPNs, memberships, travel discounts, and more DIVERSITY & INCLUSION We're committed to building a team that reflects the world. Every job description goes through a gender bias review, and we're always looking at where we can do better. Whoever you are, wherever you're based, you're welcome here.   Learn more at zenrows.com/careers
