Senior Backend Engineer, Toronto

Tilt

We're building the next century of shopping—making it feel human, communal, and alive again. E-commerce has spent decades optimizing for clicks, stripping away the trust, joy, and connection that once made shopping meaningful.

Today, we are the UK's biggest live shopping platform, and we've got our sights set on the world. We raised an $18m Series A, which we're using to rapidly grow and hire A-players to join our mission.
