  • build robust automations and services in Python or Ruby to support our internal engineering operations, taking responsibility for the quality of code you produce
  • implement tooling and automation to support development, operation, reliability, security and continuous improvement of the systems you work on
  • support the live operation of the services we run, and participate in out-of-hours support rotas where necessary - you'll be paid an allowance, and a further hourly payment, for any duties you perform when on call

  • understanding of common web security risks such as OWASP Top 10, and the corresponding mitigations
  • enjoy researching and learning new programming tools and techniques and sharing their skills with others
  • have experience working in a collaborative environment, and an understanding of the benefits of agile and multi-disciplinary approaches
  • a desire to use their skills and experience to make a genuine difference, and to work on important services that are used by millions of people

In addition to the above Senior Developers will also:

  • provide technical leadership within a team, advising and working with developers to identify the best approaches and solutions
  • take responsibility for solving complex issues, drawing upon a broad knowledge of web technologies

  • have experience in management, helping colleagues with their career development and coaching more junior staff members
