About the role

Our Engineering department is going through a phase of growth, where we have more features to build than people to build them! Most of the work is greenfield projects developing brand new features, solving some very interesting problems in transforming an industry.

We're looking for an experienced Senior Engineer to join our team and be responsible for building new and innovative products. You'll be working daily with a team of between 8-10 people in an agile squad, part of a wider community of practice in both Engineering and the Back End Guild.

We encourage you to apply, even if you might not meet all the requirements. You'll be directly reporting to an Engineering Manager, who will help mentor and guide you in your career.

  • We regularly do hackdays! We believe in a culture of innovation in our day-to-day life. Experiment with new techniques, tools and frameworks to keep Motorway at the leading edge of modern JavaScript Development.
  • Work across our collection of microservices (node.js with Express and Sequelize) that power our user-facing applications through RESTful APIs.


  • Significant commercial experience with JavaScript. In particular, experience with ES6/7 features, and technologies and frameworks such as node.js, Vue, Express or Sequelize.
  • Experience configuring, deploying and monitoring app and websites on AWS.
  • Experience working with relational databases and NoSQL databases, including complex queries and performance optimisation.
  • Understanding of web design patterns, including SOLID principles of design.
  • Previous experience working in a company scaling up is useful, but not essential.
  • Experience working in a collaborative, agile team environment.
  • Experience working with automated testing and continuous integration and delivery.
