Nice to have:

• Experience contributing to, or participating in open source projects
• An interest or experience in mentoring other members of the team
• Experience working with data-rich frontend applications, handling real-time data, and using techniques such as client-side state management to seamlessly handle background offline updates, and collaborative editing
• A love for experimenting with new ideas, tools and techniques, and exploring new technologies

What we offer

• Competitive salary of £95,000 to £125,000
• Equity in an early-stage tech company on an incredible trajectory
• 25 days holiday plus local public holidays
