[Hiring] Senior Technical Customer Success Engineer @ZenRows

Role Description

We're looking for a Senior Technical Customer Success Engineer to own how ZenRows' customers integrate, succeed, and grow. 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.

Qualifications

• 5+ years in technical CS, Solutions Engineering, or Developer Support at a developer-first SaaS.
• Ability to write working Python or JavaScript and read a customer's code.
• Good understanding of HTTP, DNS, TLS, proxies.
• Experience building something with AI that saved time (workflow, script, integration).
• Comfortable running a technical POC, reviewing account health, and engaging with VPs of Engineering.
• Strong adaptability in communication style with different stakeholders.
• Proven ability to enhance team performance and share knowledge.
• Experience with data-driven CS teams.
• Strong written and spoken English (C1 level or above).

Requirements

• Hands-on experience with scraping, anti-bot systems, proxies, or headless browsers (Puppeteer, Playwright, Selenium, mitmproxy).
• Experience in hiring, onboarding, or interviewing teammates.
• Startup background with the ability to adapt quickly.
• Familiarity with CS tools like Intercom, Zendesk, Hubspot, Amplitude, Notion, Stripe, Typeform, Metabase, or similar.
• Experience working with technical buyers or developer personas.

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.
