Hello 👋

Help us scale growth through partners and new markets

Factorial is growing fast. Every new country we launch and every partner we work with depends on how quickly and well we can build on the web.

We’re looking for a Junior/Mid Front-End Developer to help us make that happen.

You’ll work at the heart of Growth Marketing and Partnerships, building the pages, tools, and systems that power new market launches and partner-led growth. This is not about one-off landing pages. It’s about building things once and scaling them across countries, languages, and channels.

Your work will go live, get traffic, and be measured. When something works, it gets rolled out globally. When it doesn’t, you’ll learn fast and improve it. You’ll have real ownership, real responsibility, and a clear view of the impact you’re making.

You’ll collaborate daily with marketers, designers, and partner managers, helping shape how Factorial shows up to the world as we keep expanding.

If you want to build at scale, move fast, and see your work drive the growth of a global company, this role is for you.

What You’ll Do

  • Own the front-end growth surface for Growth Marketing and Partnerships: from acquisition flows and partner experiences to the systems behind them.

  • Enable new market launches by building reusable, CMS-driven patterns that scale across countries, languages, and go-to-market needs.

  • Turn ideas into experiments: build, ship, measure, and iterate on growth initiatives that reach real users and real traffic.

  • Shape our CMS and web platform (DatoCMS) so marketers, partners, and local teams can move fast without breaking things.

  • Set a high bar for quality across performance, accessibility, mobile experience, and Core Web Vitals.

  • Work closely with designers and marketers to deliver simple, fast, and polished experiences that convert and scale.

You’ll Be a Great Fit If You…

  • Have solid experience as a front-end developer, working with React and Next.js on production websites.

  • Are comfortable working in fast-moving environments where priorities evolve and not everything is fully defined.

  • Have experience working with CMS-driven websites, such as DatoCMS, Contentful, Sanity, or similar platforms.

  • Enjoy collaborating with non-technical teams and can translate business or partner needs into maintainable solutions.

  • Care about performance, clean code, and user experience, especially at scale.

  • Are interested in growth, partnerships, and internationalization, and want to understand how your work impacts acquisition and revenue.

  • Are proactive, pragmatic, and comfortable balancing speed with quality.

Bonus Skills

  • Familiarity with design systems or component libraries

  • Experience with A/B testing, analytics tools, or experimentation platforms

  • Experience with multi-market setups

  • Basic backend knowledge (Rails, PHP, or similar)

  • Animation libraries such as Framer Motion or GSAP

Why You’ll Love Working Here

  • Work on high-impact growth and partner initiatives that directly support Factorial’s global expansion.

  • Collaborate with Growth Marketing, Partners, Design, and Engineering in a highly cross-functional environment.

  • Own features from idea to launch, with room to propose improvements and new solutions.

  • Join a team that values learning, autonomy, and clear communication.

  • Build scalable systems that will be used across multiple markets and partner channels.
