Billing & Finance Operations Specialist

We want to instill cybersecurity good practices to employees in a way that's actually effective, and entertaining enough so that employees don't feel like they're working. Think Duolingo but for cybersecurity.

We created a platform to easily rollout a cybersecurity awareness program: the platform sends chat-based 4-minutes long courses to teams. Following the courses, the other side of the platform simulates phishing attacks, to prepare employees to face hackers, but in a safe environment.

Created in 2020, Riot has raised $30m with best-in-class investors (Y Combinator, Left Lane, Base10, Funders Club and Frst Capital), and is now protecting more than 500,000 employees in over 1,000 companies (including Intercom, Deel and Deezer) all over the world.

Cybersecurity is everywhere. It's impacting everyone, everyday, and it's becoming the number one risk to any organization, whether it's a small business or a big firm. Yet, the cybersecurity culture in most companies is a disaster. Hackers are leveraging this by targeting the weakest link: the employees. We're on a mission to fix that.

Our Finance team is building the foundation that will support Riot as we grow to $20M+ ARR and expand into new countries. We care about accuracy, speed, systems, and building scalable processes that will support 2–3× growth without friction.
