Become the founding member of this medical device software development team On the borders of Essex and Cambridgeshire, this diagnostics company develops medical instrumentation that provides accessible and timely results for public health purposes. Their system uses a combination of embedded C running on an RTOS, A React-Native app running on Android, and centralised data collection based on the LAMP stack and MariaDB. With products already on the market, they are seeking to move their software development in house, and are seeking an experienced and adaptable Senior Software Engineer to form the nucleus of their software team. The process of taking on board software development will be gradual, and supported by current (external) developers, so immediate familiarity with the entire stack isn't expected; however, a strong understanding of embedded development, and prior experience of developing software for medical devices (and therefore a knowledge of the associated medical software standards) will be needed. As the company is still at an early stage, you may be occasionally required to help out in other (non-software) functions of the company - you will therefore need an accommodating and adaptable outlook as well as an enthusiasm for work which will have a very substantial positive impact. You will need: A strong academic background in Computer Science, Electronics or similarly applicable subject. Substantial experience as a software engineer, including software development for medical devices. Excellent coding skills in embedded C. A can-do attitude, happy to dive into new technologies and learn new skills as needed (or indeed to help out with non-software tasks as the need occasionally arises). Full existing right to work in the UK without restriction, time limit, or sponsorship. Not essential, but useful: real-time operating systems, React Native, Android, LAMP, C# or Python. If you're looking for a role that will make a massive positive impact in the world, whilst at the same time becoming the founding member of a software team, then this may be for you. The role is on-site in a pleasant countryside location. A highly competitive salary is on offer to the successful candidate. Another top job from ECM, the high-tech recruitment experts. Even if this job's not quite right, do contact us now - we may well have the ideal job for you. To discuss your requirements call ecm or email your CV. We will always ask before forwarding your CV. Please apply (quoting ref: CV27517 ) only if you are eligible to live and work in the UK. By submitting your details you certify that the information you provide is accurate.
