Senior Technical Customer Success Engineer

ZenRows is a rapidly growing data infrastructure startup based in Europe, offering a fully remote work environment. They are seeking a Senior Technical Customer Success Engineer to manage customer integrations, provide technical support, and enhance customer success through automation and documentation.

Responsibilities:

• 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

Requirements:

• 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)
• 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
