Ruby on Rails Developer, onsite or remote within the UK

London, England, United Kingdom expand job description ↓

Description is an electric vehicle charging service. We design and manufacture the hardware, and write the software that communicates with the charge points and that the customers use to charge their car. It's a very rapidly growing industry that bridges transport, green energy, and the Internet of Things (the charge points have computers and modems). has come from humble beginnings in June 2016 - from a prototype in a cardboard box; to a metal box; to a 3D printed metal enclosure; to a sand-cast enclosure; to a die-cast aluminium enclosure tested by UL laboratories to ISO 61851. We were the first lamppost mounted public charge point in the UK. A large proportion of the cost of installing a charge point is digging up the road and laying cables. Reusing the existing power supply in lampposts dramatically reduces costs. If the trend in electric vehicle uptake continues, quite soon, we're going to need a lot more charge points.

The role

We are hiring a permanent developer to work either remotely in the UK, or on-site near Aldgate East in London.

Remote working saves on commuting and gives us a calm space to work, but sometimes face to face meetings are needed. You should expect to travel into the office near Aldgate East at least twice a month.

We are a small team so it's still possible to be heard and make a difference. You would be our third full time developer.

We do standups, planning and retros, use Github, Slack, CircleCI, Rails, AWS, Terraform, Ansible, and do TDD by default. We have a strong code review culture, pair when it's useful rather than by default, dress casually, and have flexible working hours.

Benefits include 25 days holiday, 10 "innovation days" to explore your own ideas, maternity and shared parental leave, a conference budget, and an Apple laptop. See below for other benefits.

And most of all, an opportunity to make a meaningful improvement to our environment!

We are hiring to help us:

  • Improve the customer's charging experience
  • Automate the process of configuration, testing at manufacture and installation
  • Make the IoT monitoring more comprehensive and reliable
  • Expand the customer portal for better usage statistics
  • And grow!
