Help us move the needle on MRR

At Factorial, the Growth Marketing team is the driving force behind experimentation and innovation to find new distribution channels, optimize our acquisition funnel, and increase the volume and quality of leads. We are also the only technical team in Marketing, supporting over 100 stakeholders across content, SEO, events, partnerships, paid media, and more.

We’re looking for a Senior Developer who can thrive in ambiguity, move fast, and balance high-impact growth experiments with strategic, long-term improvements — like evolving our CMS and scaling our web platform.

The annual salary range for this position is €51,000 to €70,000.

What You’ll Do

• Lead front-end implementation for growth experiments across our marketing website and acquisition funnel — build, test, validate, iterate.
• Modernize our CMS integration (DatoCMS) to support scalable, flexible content structures. You’ll help us evolve away from legacy limitations and enable better workflows for both devs and non-devs.
• Collaborate with Marketing and other teams to bring high-quality, fast-performing, visually compelling pages and campaigns to life — animations, interactions, mobile-first execution.
• Be a multiplier for the team by mentoring developers, advocating for quality, and raising the technical bar through communication, documentation, and reviews. You will partner with another senior developer and be part of a team of mid-level developers and product designers.
• Support internal teams by building reusable components, scalable templates, and internal tooling that allow 100+ stakeholders to operate more efficiently and autonomously.
• Own experiments from code to data : Contribute to defining success metrics, integrate tracking, analyze outcomes, and iterate based on learnings.
• Keep performance top of mind — deliver high Core Web Vitals scores while supporting delightful, creative UI / UX solutions.
