Fullstack Engineer (Backend-leaning)

About the Company

We’re working with a fast-growing SaaS start-up on a mission to turn the customer journey into the most powerful business tool there is.

They’re fully remote, global from day one, and building with the kind of ambition (and energy) you only find in companies rewriting the playbook. Instead of constant transformation projects and endless complexity, their platform helps some of the world’s biggest brands simplify, scale and grow smarter.

The traction’s real. Their product is already trusted by household-name enterprises, and the team behind it is scaling fast—80+ people, 30+ nationalities, spread across 20+ countries.

And here’s the fun part: they’re only just getting started.

What you’ll do

As a senior full-stack engineer with a backend mindset, you’ll spend around 60–70% of your time on backend systems, while also pitching in on frontend polish and performance when needed. You’ll get hands-on impact across areas like:

• Build integrations at scale — connect with tools like Miro, Figma, Salesforce, Snowflake, BigQuery, and more.
• Power real-time collaboration — enhance multiplayer features with techniques like fractional indexing and CRDTs.
• Develop AI-powered experiences — partner with the AI team to surface insights from customer journey data.
• Support frontend performance — contribute to the design system and craft fast, reliable user experiences.
• Own your work — plan, prioritise, and ship in an async-first, minimal-overhead environment.

What we’re looking for

• An ambitious engineer with a growth and learning mindset, and with a passion for building performant and scalable systems.
• Prior experience building data integrations at scale is a bonus.
• An engineer who wants to be at the foundation of a fast-growing team.
• A product-minded engineer that wants to understand how people use our product and why.
• An asynchronous worker who organises and documents their work.
• A clean coder who writes well-structured and maintainable code, through tests and documentation.
