Fresha: Shaping the Future of Beauty & Wellness

Join Fresha, the leading marketplace platform transforming the beauty and wellness industry globally. With over 120,000 businesses and 450,000 stylists trusting our platform, we've powered over 1 billion appointments worldwide. Fresha empowers businesses with an all-in-one platform for bookings, point-of-sale, marketing, and more, while connecting consumers to local services.

At Fresha, we believe AI is a force multiplier for feature delivery, not just a coding assistant. We provide every engineer with top-tier tooling (Claude, GitHub Copilot, Cursor) to strip away technical toil—so you can focus your energy on shipping high-impact product features. We value engineers who know how to leverage these tools to drive momentum within our 6-week cycles, accelerating the journey from concept to code while maintaining the deep technical judgment to verify, secure, and own the final user experience.

To foster a collaborative environment that thrives on face-to-face interactions and teamwork, all Fresha employees work in the office four days per week, with the flexibility to work remotely on Wednesdays. London office: The Bower, 207-211, Old St, Tower, London EC1V 9NR
