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

Your Impact as a Staff Backend Engineer

Are you ready to make a significant impact in a fast-paced, autonomous environment? We're seeking an exceptional Staff Backend Engineer to join our cross-functional product team in Warsaw.

Take ownership of architecture for a tribe

Guidance - Sought out for technical guidance; anticipating technical issues at the product level and making architectural and design decisions to avoid them

Improvements - Create sweeping improvements in stability, performance and scalability across major business-critical systems

What we are looking for

AI-Augmented Workflow: You have deep experience building and interacting with AI agents, using them to amplify your output to 5x that of manual coding.
