Full Stack Engineer – Ruby on Rails

at Koru Kids (view profile)
Location London, United Kingdom
Date Posted January 3, 2019
Category United Kingdom - Tier 1 Visa Jobs
Job Type postgresql


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.


  • Familiarity with web application development
  • Familiarity with relational databases and SQL
  • You take pride in writing readable, well-designed and well-tested software
  • You’re keen to pair program when appropriate, and generally enjoy a culture of code review
  • You’re humble, you lap up feedback, and you want to learn
  • You roll with it. You understand that startups are unpredictable environments, and are comfortable with a degree of chaos
  • You own it. You take responsibility for your work from start to finish

Not essential, but nice to have

  • Experience with Ruby on Rails
  • Familiarity with frontend development, including modern JavaScript frameworks and tooling
  • You practice test-driven development
  • A degree in Computer Science or a related field
