Full Stack Engineer

London, England, United Kingdom · Engineering


Koru Kids is growing quickly. We’re on a mission to improve childcare in London, and looking for someone experienced, creative and friendly to join our team as our fifth engineer.

About Koru Kids

Koru Kids is on a mission to improve childcare in London, making it easier and more affordable for families to access flexible and high quality childcare. We are backed by fantastic investors, including top VCs who’ve backed companies like Wonderbly, Thread and Appear Here, as well as the founders of Gumtree and Entrepreneur First. We won ‘Best Technology’ at the Business Women Awards 2017, and are currently shortlisted for a number of awards including Startups ‘Tech Business of the Year’.

About the role

We’re building a marketplace that enables families to find and share high quality nannies. As an engineer on the Koru Kids team, you’ll be designing and building tech to make complex matching problems a breeze, to give families and nannies a solution that just works, and to supercharge our nanny recruitment and training processes.

You’ll be working in Ruby for most of the backend, with Rails, PostgreSQL and Redis making up the majority of our core product. You’ll be using modern frontend tooling, with ES6, React and Tachyons. When it comes to shipping code, you’ll be sending pull requests and doing code reviews in GitHub, and checking that CircleCI is happy before anything goes live. You’ll mostly be deploying to Heroku, with some heavy lifting on AWS. (That said, our priority is making sure we’re using the right tools for the job and we’re open to adding to or changing up our tech and tooling as appropriate.)

We’re continuously improving our product, building key features that will move the needle in a big way. Instead of an endless product roadmap, we run short development cycles to test assumptions and make smart decisions quickly. We favour feature flags over staging environments and deploy to production as often as we need to; deployment cycles shouldn’t get in the way of delivering value. As an engineer on the team, you’ll work closely with product and operations to find and build creative solutions for business problems and make sure we’re delivering the most value to our customers.

About you

You’re a mid-level or experienced generalist or backend web developer who thrives in small, fast-moving engineering teams.
