Meet the team behind this journey

We're looking for Senior Backend Engineers to join two closely collaborating platform teams responsible for our core text backend services. The teams build these services by integrating advanced neural networks from our research department. Team one is focused on providing APIs to other teams and our customers, with a particular focus on implementing API requests using neural network inference jobs. Team two focuses on efficiently scheduling these inference jobs on our neural network infrastructure using a custom load balancer that dynamically optimises for latency and throughput. Both teams work closely with the research department to provide state-of-the-art AI technologies to other teams within the company and to our end users.
