Job Description
Kulu is an AI startup, backed by some of the world’s leading investors including Antler (backers of Lovable and Airalo) and Redbus (backers of Cleo). We are building AI agents for software companies that run video calls with their users to get them onboarded. Imagine joining a Zoom call with an AI to help you get set up using a new piece of software - just share your screen and speak with the AI as it guides you through configuration.
Kulu is led by a rockstar founding team: Ed (CEO) - 1st PM at Teya ($1b+ valuation in 2 years) and one previous exit. Rio (CTO) - PhD in AI, specialising in neural networks and CV. Oscar (CCO) - Former Head of Sales at multiple VC-backed companies.
Kulu has two offices: London - Commercial Office, and Bali - Product & Engineering Office. The founding team works from both locations.
The role is based in Bali and we can offer a relocation package for the right candidate. The role will start as a contractor with a view to it moving full-time depending on performance.
