Software Engineer - Tonejet

  • Location
    Cambridge, United Kingdom


Tonejet Limited is seeking an experienced and talented Software Engineer to join its growing Engineering team. The successful candidate will have a strong background in developing .NET (C#) software for machine control or test and measurement.

The Software Engineer will have the support of a strong team but will need to be able to take responsibility for driving projects ranging from bug fixes to new-feature development through to completion.

The Role:

Tonejet develops cutting-edge technology and products in digital printing, based on our proprietary electrostatic drop-on-demand ink ejection technology. Our current focus is on the Cyclone machine, designed for digital printing of metal packaging. As part of a dynamic, creative and inventive team you’ll be given the room to grow your skills and specialise in the areas you excel while retaining the broad variety of day-to-day work.

As a software engineer at Tonejet your contribution will be immediate, involving a mixture of hands-on development with machines and systems, product improvement programmes and ground-up design work, which might include:

  • Design and development of machine control software
  • Low-level hardware interfacing
  • User interface development
  • Image processing
  • Development of test systems and software
  • Supporting system test and commissioning


Qualifications and Training:

  • 1st or Upper 2nd Class Degree (2:1) in Science or Engineering.

Skills and Experience:

  • Experience in the following areas of software development is desirable
    • UI/UX design and implementation for complex machines or equipment, using WPF / XAML.
    • Understanding of the MVVM architectural pattern.
    • Interfacing with low-level Hardware like PLCs / Sensors / embedded systems / networked devices.
    • Robust architecture design for software solutions, demonstrating modularity and loosely coupled interactions between sub-systems.
    • Unit Testing / Scripted Testing for improved software testing and robustness.
    • TCP/IP based network communications between applications and systems.
    • Asynchronous programming for .Net.
  • Planning projects for deploying new features / improvements to software.
  • Experience of Continuous Integration / Continuous Deployment using Microsoft Azure DevOps would be an advantage.
  • Some experience or knowledge of image processing and manipulation for industry formats would be desirable (but not essential) for this role.
  • Some PLC programming experience is desirable
  • Demonstrable skills in creative problem solving of complex systems would benefit your application – often a problem reported as a software error has an ultimate root cause outside of the system software.
  • You have initiative, good communication skills, attention to detail, an analytical and innovative approach and the ability to thrive under pressure.
