Job description

Our client helps hundreds of thousands of businesses collect data in a way that feels... well, human. From slick surveys to interactive forms, they're redefining digital engagement—with the help of an engineering team that knows how to ship smart, scalable software.

They’re now hunting for a Senior Fullstack Engineer who loves building seamless, end-to-end product features. You’ll work across the stack (React, Next.js, Node, TypeScript), tackle gnarly bugs, design scalable systems, and occasionally mumble to yourself in YAML. Bonus points if you enjoy debugging flaky CI pipelines while caffeinated.

You’ll:

• Build modern, beautiful web apps and robust backend services
• Write clean code, test it properly, and ship with confidence
• Collaborate with designers, PMs, and fellow engineers who speak fluent emoji
• Help define best practices, review code, and drive platform reliability

You bring:

• Real-world fullstack experience in tech first businesses whether in ScaleUp or slightly more established.
• A track record of handling complex engineering tasks and the ability to not just implement but to handle stakeholders and design tasks - ie taking accountability for the build.
• Solid CI/CD chops (GitHub Actions is a plus)
• A love of good UX and clean architecture
• CompSci or STEM background from a Top University with >4 yrs experience. Educated either to a 1st class or 2:1 degree level or have significant experience and a polished track record.
• A desire to build things people actually like using

Learning budget, async culture, great people—and zero patience for ego. Ready to build the future of forms? Then let’s talk.
