24sessions is innovating customer interaction. We are a fast-growing scale-up in Amsterdam. Our SaaS solution is leading across Europe when it comes to customer interaction via video-chat. We are helping organizations like Rabobank, ING, AEGON, shape the future of customer satisfaction. Google, McKinsey & Rocket Internet recently elected us 1 of the 10 best B2B startups in Europe! 24sessions has been expanding rapidly and we want to remain the best video solution in the market.

About the role

Part of being the best video solution is making sure our virtual video-meeting environment runs like clockwork. Our product team consists of 2 squads. As Sr Backend Developer you would become part of the squad responsible for the meeting room and microservices that provide video connectivity, work with real-time video data, and video call management.
