Percyroc is looking for a motivated software developer for implementing a software layer connecting the different parts of the solutions. Our team wants to expand competence with an experienced software architect with a hands-on approach to coding. Earlier exposure to AI-related techniques such as Reinforcement Learning, and frameworks as Scikit-learn is preferred. Coding will mostly be done using Python, with an understanding that many of the hardware-related intricacies require other appropriate tools. It is important for the applicant to help the company in a broad perspective, and to take an active role in organisational, managerial and business-related tasks.


The core responsibility of the candidate is to code, debug and maintain embedded software for connecting the different parts of the solution offered by Percyroc. This requires also a keen interest in new developments in the broad areas of machine learning and AI, and of automatic control. The candidate will work closely with the RF/hardware experts, hence should have excellent communication skills as well as display an openness to learn about related technologies.  The successful candidate is expected to take on an active role in the daily operations of the company.


At least 1 year professional experience as a software developer with a focus on embedded systems. A university (master) degree in machine learning, automatic control, computer science or equivalent. A relative junior, flexible profile, with a base in Sweden, Uppsala. Personal drive, have the ability to take own initiatives. Innovation driven, provide innovative solutions to common problems. Ability to maintain good long-term relationships with our customers. Fluency in English both oral and in written.

In return, we offer a competitive salary level, flexibility of employment, a challenging and exciting work environment and a tight connection to academic institutes.
