We are currently looking to recruit a Senior Javascript Engineer for a fixed term role of 6 months initially who will be responsible for planning and implementing cross-stack web applications. Working as part of small cross functional teams, this role will report to the Software Engineering Manager, and will be relied upon to support the SEM and the wider business in building enterprise grade bespoke software solutions within the domain of learning and training.


About you

Are you someone who is passionate about delivering high quality code, with a
focus on security and performance, whilst maintaining a great eye for detail in
the implementation of web UI.
We are a small agile team and whilst we all work independently, love
collaborating to find the best solutions.

Essential skills and experience

  • JavaScript: This is the foundation of much of our application development, so extensive industry experience here is key. We use this in a number of forms but mainly:
    • React for the frontend
    • Express for the backend
  • HTML/CSS: Seems obvious, but we are serious about high quality HTML to ensure that we can deliver enterprise level experiences that are accessible to all.

Additional skills that we look for

Whilst not critical, these tools are a big part of the work we do, and any
experience you have with these would be great:
  • GraphQL
  • Typescript
  • PHP
  • Python
  • MySQL/Postgres
  • Git
  • Docker
