Junior electronic engineer / firmware programmeR

Many Pebbles are looking to bring on board a junior electronic engineer / firmware programmer to work on ongoing research and development projects as well as other commercial projects as they arise.

Many Pebbles is based in South London (Brixton) and undertakes diverse and interesting engineering projects including wearable technologies, robotics, Internet of Things (IoT) devices and consumer electronics. No project is the same and project involvement can range from simply supporting in specific technical aspects to driving product development in its entirety from initial concept to ongoing manufacture. We work with a number of different organisations and benefit from a great deal of repeat business.

Some flexibility in working practice will be required (e.g. working on-site with clients or suppliers) and the role will likely commence as a part-time commitment with a view to moving full-time in the near future. Given the diversity of the work undertaken by Many Pebbles and the fact that we are a small team, the remit of the work undertaken will likely be broad and determined predominantly by commercial drivers.
