Back-end Ruby Engineer

About Koru Kids

Koru Kids is building the world’s best childcare service, starting in London. We’re making it easier and more affordable for families to access high quality childcare. We’re growing like crazy, backed by some of the best investors in Europe, and we’ve won a bunch of awards.


A little about the role

This role is perfect for an experienced Ruby Engineer who wants to continue to hone their craft in a software, data and content start-up about to enter a hyper growth phase.

We have a mature and stable tech stack and a healthy code-base, built with a strong focus on quality and best practices, which allows for fast design iterations, short development cycles and quick fixes when challenges spring up.

We’re not a deep tech company - we’re providing a tech solution to a complex human interaction problem. Ultimately we are reinventing one of the last essential areas of our social infrastructure that remains largely untouched by technology.

Cool things you could work on

Helping us scale our public transit time and routing services, enabling lightning quick calculations of transit time between hundreds of thousands of families across London and beyond.

Refining our search algorithms and building tools to make complex ‘matching’ problems a breeze, to give families and nannies a solution that works.

Designing our payroll infrastructure, supporting thousands of individual employee shift submissions every month, ensuring we invoice our families and pay our nannies accurately and on time. This will eventually extend to being a fully fledged scheduling and shift management tool.
