This is an exciting role with the ability to impact our growth by working in partnership with our key customers. You should be someone who is happy to speak with customers, understand the problems they are looking to solve and then propose and implement solutions. This will often be combining technology we have already built with custom developed software to solve the client's unique requirements.

As an Engineer you should be able to work with your teammates across engineering and other disciplines to plan and implement the technical side of features. You should be driven to keep learning and developing your skills and have a strong understanding of where you need to develop your skills.

Our backend is built around the Django framework with a PSQL database. We use Django to help keep us focused on the features which are unique to our business and deliver value to our customers. We host our services on AWS with the full infrastructure and deployment process defined in AWS CloudFormation and Ansible. Much of the work we do is ingesting data from EVs and Chargers and sending back instructions on how to charge.  This means that a lot of our code is triggered outside of the context of a web request and for that we use the Huey task queuing system. You should be familiar with these tools (or similar like Flask or Celery) and be excited about the challenge of building a system which can handle the scale and complexity of managing the charging of EVs across the world. enables consumers to charge their EVs in the most cost-effective and least carbon-intense way possible, whilst saving them money!

Since we were incorporated three years ago, we’ve grown from 0 to 10,000s users, raised a funding round, collaborated with 15+ energy companies and saved tonnes of CO2. We were part of Microsoft’s first AI for Good cohort, won the EDF Pulse Innovation Challenge and were named “Best Energy Startup in the World” by Free Electrons 2019.

Our goals are:

  • Scale to 1 million users in the next 3 years!

  • Launch in five new markets worldwide, including non-English speaking markets and non-EU timezones;

  • Make our app work for users across different geographies, with various vehicles, charger manufacturers, and energy suppliers;

  • Deliver new charging services (like charging on public charging networks and giving users more flexibility in how they charge);

  • Improve our data and analytics offering for our Utility partners so they can better understand how smart charging stabilises their grids and reduces their costs.

  • Worked with a similar technology stack of Python (Django), PSQL, Celery (or similar) and AWS for multiple years;
  • Proven experience leading the technical development of a product which can scale quickly whilst staying performant;
  • Strong written communication skills, as a remote team written skills are highly valued;
  • Can communicate effectively to people with a range of job roles and backgrounds;
