About the role

As a Senior Backend Engineer, you will be required to produce and implement functional software solutions on our Optimization service. You will work with Product Managers and other Engineers in a cross-functional team to implement key features that will provide tangible results to the success

Optimisation is key to scheduling at scale. Our solution needs to free schedulers up to deal with the exceptions they encounter every day, and we do that by optimising schedules automatically. Optimisation is a complex problem - companies want to optimise for those variables that most directly impact their business, whether that’s resource utilisation, travel time, cost, continuity of care, other factors, or combinations of many factors.

We need you to help us continue our optimisation journey.

As a Senior Backend Engineer, you will be responsible for delivering performant, scalable solutions that meet the growing needs of our largest customers. They are able to clearly determine business requirements, model the underlying business domain, create documentation that other team members can leverage to deliver value to the end-users, and understand nuances related to microservice design.
