Embedded Software Engineer

As the R&D Embedded Software Engineer you will be a member of an international R&D team who develop sophisticated sensors to monitor environmental emissions and to optimise industrial processes. Our centre of expertise is focussed on the measurement of dust at very low concentrations (mg/m3), the mass flow of solids at high concentrations (tons/hour) and flow of exhaust gases, all in harsh industrial environments. This is achieved by using a range of technologies such as laser scattering, electrodynamic, capacitance, microwave and ultrasonic.

You will work in a team of scientists and engineers to develop analogue and digital hardware with embedded software for innovative sensors to measure dust, solids, and flow. You will be responsible for the full software lifecycle from system design, firmware implementation, testing and deployment to hardware. You will implement and test metrological algorithms and take certified emission monitoring (QAL, AMS) and functional safety (SIL) into account.

You will maintain existing products throughout their life cycle; this includes revising the embedded software components as required by hardware design changes.

You will participate in the development, testing and deployment of software and hardware for PC/tablet/smartphone systems.

You will create and maintain technical documentation in the form of design, test and functional documents, which can be used as a basis for the creation of manuals and the approval of the devices

• Team collaboration, capable of working within a broader software team and conducting peer code reviews.
• Legacy code maintenance, handling bug fixes and software updates throughout a product’s lifecycle.
• Education: Degree in a relevant field or equivalent industrial experience.

Desirable Skills

• Safety-certified code design experience.
• Knowledge of ISO 28119 software testing standards.
• ISTQB-certified tester qualification.
• Software development for Linux, Android, RTOS, and AWS environments.
• Analog and digital hardware design understanding, including:

We work in a cross-border, collaborative environment with ENVEA development teams in France, US, Finland, Germany and the UK. Our core team is located in Cambridge, UK, and Schliengen, Germany. Our collaborative environment uses MS Teams/SharePoint/Office 365 and JIRA/Confluence to work together. Effective communication and teamworking skills are essential. We organise our work in an agile manner where possible to achieve our targets.

The working language is English; knowledge of German is beneficial.

The role is based in our office in Swavesey, Cambridge UK.

There are opportunities to travel to other R&D sites within the ENVEA group and to customer sites where appropriate.
