Software Engineer


Microsaic is a small world leading manufacturer providing cutting edge instrumentation to the chemical industry.

The company manufactures a small Mass Spectrometer which is being targeted at a range of environments including drugs manufacture. The software team provides an application which both controls the instrument’s functions and displays and analyses the data retrieved. The main application is written in Java, and we are developing a new Web GUI for the Mass Spectrometer.

Current work within the software team:

One key project is to develop a new web GUI, which is expected to eventually replace the existing Java Swing GUI. We will develop this using an Agile style process, where we get our stakeholders to pick what features should be implemented next and frequently review progress. Our new developer will have a key design role in the project, including recommending which technologies to use.

Other projects the new developer will be involved in include a major refactor of the existing java code base, which is particularly challenging.
We are also working on new features that allow the mass spectrometer to be used in exciting new fields, such as drugs manufacture and automated reaction monitoring.
Note that this is not an embedded software role – the mass spectrometer includes a PC motherboard running Linux, and we use normal development tools to develop the software.


We require an intermediate level software engineer with experience developing software in Java and experience developing Web GUIs, to join our small software team.

The role would suite a developer with a few years of commercial development experience who would like to take on more responsibility. We are a small team and everyone has a big impact. There is a lot of interesting science going on in the office, which greatly adds to the interest of software team’s work.
