Staff Frontend Engineer

Staff Frontend Engineer (EMEA)

Born out of the heart of the Basque Country in Bilbao, ZenRows is one of the fastest-growing startups in Europe! We work 100% remotely and believe in hiring the best people, no matter where you are in the world!

Founded in 2021, our mission is to transform the future of data workflows by enabling seamless, large-scale data extraction from the web. With our powerful tools, businesses can automate data collection at scale while leveraging the most advanced anti-bot bypass system on the market. Thousands of companies worldwide - across industries like e-commerce, real estate, finance, and AI - rely on ZenRows to streamline their data pipelines, fueling automation, analytics, and AI-driven insights.

As we continue our rapid expansion, we are now looking for a Staff Frontend Engineer to join us on a permanent basis and make an instant impact.

The Role:

We're hiring a Staff Frontend Engineer to take product and technical ownership of our frontend: someone with a strong product mindset, a genuine AI-forward way of building, and the seniority to set the bar for how we ship. This is a frontend-specialist role first, working alongside dedicated Backend Engineers, but there's also room to contribute to and operate backend services/APIs with their support, if that's where your curiosity takes you. You'll work closely with our CEO, and our Director of Engineering.

What You'll Do

• Own features end-to-end — from framing the problem with Product to shipping and measuring impact, across onboarding, activation, dashboards, and billing/account UI. You're judged on outcomes, not tickets closed.
• Build with an AI-first mindset — use tools like Claude Code, Copilot, or Cursor as core leverage, and go further: find where AI can improve the product itself (smart onboarding, AI-assisted setup, in-product guidance), prototype it, and advocate those ways of working across the team.
• Instrument what you ship — event tracking and dashboards (Amplitude, Segment, BigQuery, PostHog), so every feature comes with a way to know if it worked.
• Run experiments — A/B test and iterate on activation and conversion based on real usage data.
• Collaborate widely — with Product, Marketing, Sales, Support, and the Backend Engineer(s); help shape API design, and pick up backend work with their support when it makes sense.
• Set the technical bar — clean, well-tested React code, and mentor other engineers as the team grows.

What We're Looking For

• 8+ years of frontend/product engineering experience, with real Staff-level scope (technical leadership, not just tenure).
• Deep React expertise and a strong design sensibility for polished UI.
• A genuine product mindset — you can point to outcomes and metrics you've driven, not just features shipped.
• Active, hands-on AI usage in your workflow, ideally with examples of pushing it into the product, not just your own productivity.
• Experience with funnel analytics and instrumentation, and familiarity with A/B testing.
• Comfortable working against APIs built by others, with the judgment to specify a good contract — and open to picking up backend/API work yourself when it's useful.
• Confident communicator — clear with non-technical stakeholders, and unafraid to push back on technical founders when the data supports it.

What Makes This Different

• Full ownership. You'll own systems end-to-end — design, deployment, and operations. No handoffs to an ops team, no waiting for someone else to ship your work
• Direct impact. The systems you build directly affect customer SLAs, billing accuracy, and the core product success rate. You'll feel it
• No layers. You'll work closely with our CEO and Director of Engineering — both technically deep — without three layers of management in between
• No methodology theater. We skip the ceremony and give you a horizontal view of the problem. You decide where you can have the most impact

Why you will love working here…

• Our people crave ownership and opportunity over everything else. We offer responsibility and scope to do things in your role that you can only dream of in similar roles in larger companies.
• We have a CEO who values world-class talent over everything else. Trust and respect are earned, and with them come reward and recognition like nowhere else.
• In a world where it feels like everyone is being called back to being in an office, we operate a truly 100% remote approach that allows you to work from anywhere you choose.

Forget Agile, Scrum, Lean... or whatever development methodology is trendy this week. We give you a horizontal view that enables you to identify where you think you can contribute the most.

We have fun! The above may sound like we are all about work, but we put a lot of focus on ensuring our culture is one that our people enjoy, which lets you build lasting friendships and grow both personally and professionally.
