Gizmo is an AI startup on a mission to make learning so easy that anyone can learn anything. We're building Duolingo for anything - a platform that uses gamification and social mechanics to make learning fun.

With over 1 million monthly active users and $4M in annual recurring revenue, we’re already one of the fastest-growing startups in the UK. Backed by leading investors, we recently raised $22M in Series A funding to accelerate our vision of helping 1 billion people learn.

You’ll work closely with our wider engineering team to build, test and ship features that bring our vision to life. You’ll be joining a fast-paced, collaborative team during an exciting stage of growth, with plenty of opportunity to make a significant impact and grow alongside us as we scale.

Key Responsibilities:

  • Happy to work hard for a chance at building something great!

Benefits

  • Highly competitive salary.

  • Hybrid working model with 4 days in our East London office, ideally located between Shoreditch High Street, Old Street, and Liverpool Street stations.
