Developing real-time control and sensing firmware for high-tech healthcare systems

Cambridge; Excellent + benefits

Specialising in firmware for control and sensing systems, this role will involve you in the development of robotics for the healthcare sector. You will be a key member of the team, working alongside domain experts from a variety of technical backgrounds, and turning initial concepts and algorithms into high quality, tried and tested code, ready for deployment.

Development will be in C for ARM processors and will entail you gaining a full understanding of how the overall system works and how requirements originate. Once up to speed, you will be able to contribute to technical discussions and influence design decisions. If you enjoy bringing hardware to life, and are looking for a role with a broad remit rather than being fed small individual work items, this may fit the bill.

You will need:

• A strong academic background with a 1st or 2.1 degree in computer science from a respected university and good supporting A-level grades (or equivalent).
• Excellent real-time embedded software engineering and debugging skills with C or C++ on ARM microcontrollers (STM32 experience is ideal). Languages such as Python, Java, or C# will be useful to support the development of specialised test harnesses. Day to day development will be within a Linux environment.
• Good familiarity with debugging paraphernalia such as probes, oscilloscopes, and logic analysers, and the ability to read schematics and data sheets for electronics.
• You will need existing UK work permission without time limit or the need for sponsorship.
• This role is fully on-site, so you will need live or be able to relocate to the vicinity of Cambridge.

Based near Cambridge, this company is at an exciting stage in their development with an entrepreneurial start-up mindset, and the security and resources stemming from a mature parent company. The role features a highly competitive salary and benefits package.

In this senior engineering role, you will help shape the software component of their system. Written in C++ and increasingly in Rust, this code runs in a Linux environment, and is responsible for control functionality and oversight of the hardware. You would be contributing to its design, development, test, and deployment throughout the software development lifecycle. Aspects you might typically be involved in include concurrency, threaded programming, communications protocols, and maximising performance by leveraging CPU and memory architectures. You may well also be called upon to impart your knowledge to less experienced engineers and to collaborate with colleagues and stakeholders, including from non-engineering specialisms.

You will need:

• A good degree in computer science or related discipline from a well-respected university.
• Demonstrably excellent software design and implementation skills, including strong skills in C++ and at least an interest in using Rust.
• A good understanding of DevOps techniques.
• Good communication and team-working skills and an analytical approach to problem solving.
• Full, existing, and unrestricted UK work permission.

This is a great opportunity for an accomplished Senior C++ Developer with a penchant for thinking outside the box to push the limits of highly optimised code. Whilst highly profitable, this company was founded primarily with altruistic aims in mind - a philosophy that includes taking good care of their employees and providing a friendly and supportive workplace culture. They offer a competitive compensation package including performance-based bonuses. Hybrid working is available for up to two day per week with the remainder being based at their Cambridge offices.

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.
