Our clients include Google, Apple, Microsoft and public sector organisations such as the Department of Transport and Transport for West Midlands.

The role

We are looking for a talented Technologist to join our development team at Ito World. Bringing strong technical skills and experience defining, building and supporting complex software products, you’ll develop a deep understanding of our transit data systems.

  • Work with the team to ensure that projects are completed on time, communicating progress with stakeholders.
  • Work with product teams and customers to decompose complex requirements into simple subsystems for the team to implement.
  • Show a passion for people, caring deeply about our engineering culture and the team’s wellbeing and development, doing all you can to continue making Ito World a great place to work.
  • Help to address production support issues, minimising data loss and customer impact.

What you need to have

  • Strong technical skills, with at least 5 years experience of Python, C++ or Java, and a solid familiarity with cloud based deployments.
  • Excellent interpersonal, written and verbal communication skills.
  • An ability to review and constructively feedback, helping others to learn.
  • Understanding of all aspects of the software development lifecycle including knowledge of (and preferably experience with) agile methodologies.
  • A strong grasp of software quality and how to ensure development practices lead to high-quality outcomes.

What would be desirable


  • Exposure to the transit system or logistics problem domain such as routing techniques, transit planning, or scheduling.

What you need to be

  • Organised with a good eye for detail
  • Comfortable guiding teams through Agile/Scrum development methodologies
  • Familiar with software development in a Linux environment, CI/CD Pipelines and container-based deployment paradigms
  • Innovative and creative in your approach to software development
  • Collaborative, and able to communicate effectively with other managers, developers, testers, product managers and customers.
  • Passionate about software quality.
