Career

Percy Roc is looking for a highly motivated and ambitious materials chemistry PhD candidate who wants to complete their doctoral studies in an industrial setting, in connection with Uppsala University. You will perform studies in a project which aims to develop new energy-efficient heating processes addressing several parts of the battery value chain. Percy Roc’s microwave technology will be implemented in the synthesis of battery materials for both lithium- and sodium-ion batteries, in electrode drying and in regeneration of spent battery materials. In addition, you will employ a full range of materials characterisation techniques, including advanced spectroscopic, imaging and structural methods, as well as electrochemical techniques, to gain a deep understanding of the physical and chemical processes occurring during heating.

Basic Qualifications 

The candidate must have:

• been awarded a second-cycle qualification, or
• have completed at least 240 credits in higher education, with at least 60 credits at Master’s level including an independent project worth at least 15 credits, or
• acquired essentially equivalent knowledge in some other way in Sweden or abroad.
• very good oral and written proficiency in English.
• a second-cycle degree or equivalent as above in chemistry, physics or materials science.

Preferred Skills and Experience 

• knowledge of electrochemical energy storage systems, preferably with previous experience of working with or studying such systems, is valuable
• previous experience with materials characterisation in work or thesis project is an advantage
• previous experience or knowledge of microwave heating and/or materials synthesis is a merit
• previous experience working in an industry setting or developing instrumentation is a merit
• excellent communication, dissemination and outreach skills are a merit
• excellent grades from second-cycle education are a merit

Application procedure:

Submit your application using this form. The application must contain the following attachments as a single or multiple PDF documents:

• Cover letter detailing why the candidate is interested and suitable for the specific position
• CV
• Copies of degree certificates and grade transcripts
• Master’s thesis or similar (final/draft)

Percyroc is looking for a motivated system engineer 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.

RESPONSIBILITIES

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.

BASIC QUALIFICATIONS

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.
