Job description

Do you want to shape the future of next-generation energy technology at a fundamental level? At Epishine, we are looking for a senior R&D profile who can bring new perspectives, challenge existing assumptions, and help translate advanced material and process insights into real, scalable technology. This is a role for someone who thrives in complexity and wants to make a tangible impact on how cutting-edge innovation becomes reality.

Epishine is a Swedish energy impact company, reimagining the capture of light with market leading printed organic solar cells. Our technology captures indoor light to make electronics self-powered, making cables, disposable batteries and unnecessary maintenance a thing of the past. At Epishine, we foster a culture of collaboration, creativity and innovation where we encourage our employees to challenge the status quo and drive innovation. Our company is now growing and we are looking for more driven talents who want to grow and develop together with us! Go to www.epishine.com to read more about Epishine and our vision.

The mission

As Senior R&D Engineer, your mission is to strengthen and accelerate our technology development by connecting deep technical understanding with practical implementation. You will work hands‑on with our materials and processes to understand their behavior, identify limitations, and define what needs to be improved or rethought. Based on this, you will drive and support development initiatives, from material improvements and new processing approaches to solving complex challenges impacting performance, reliability, and scalability.

You will work closely with our R&D Director Thomas and act as a senior technical contributor and sparring partner, challenging assumptions and highlighting blind spots.

You will take ownership of selected R&D projects, shaping direction, defining experiments at a high level, and ensuring progress from idea to validated results. Operating at the interface between innovation and execution, you will help translate new concepts into solutions that work in practice and align with production needs.

You will be based in our headquarters in Linköping where we have both our offices, factory and laboratory. You will be working closely with our entire R&D team, and you report to our CTO.

Who are we looking for?

We are looking for a highly experienced and intellectually curious R&D professional with a genuine passion for science and technology. You combine deep technical understanding with the ability to turn insights into action, and you actively engage with your field beyond your day‑to‑day work, whether through writing, discussions, or continuous exploration.

You likely have:

• A PhD in physics, materials science, or a related field (ideally within third‑generation semiconductor materials such as transistors, perovskites, or similar)
• Around 10+ years of experience working with advanced materials or processes in a relevant industry (e.g. photovoltaics, semiconductors, coatings, or similar)
• Experience working with emerging technologies where design rules are not yet fully established, ideally in a start‑up environment scaling new technology toward commercialization where you had the leading role in defining the technology
• Had in‑depth conversations and thought about solutions for the entire (up‑and downstream) supply chain in previous positions, solving complex problems in unexpected ways
• Excellent communication skills and fluency in English
• An interest in the technology beyond the technical, bordering the philosophical

As a person, you are analytical and solution‑oriented, with the ability to understand complex problems and challenge assumptions. Having several thoughts in the head at the same time while optimizing a multidimensional landscape will be the natural state of your everyday work. You translate ideas into tangible outcomes, communicate clearly, and work effectively across teams. You are motivated by working at the frontier of technology and contributing to solutions with real‑world impact.

What do we offer?

At Epishine, we offer the chance to be part of an exciting journey and the opportunity to contribute to a more sustainable planet. Additionally, we offer a secure employment with pension and insurance benefits, yearly wellness allowance and a friendly company culture where collaboration, innovation and sustainability are at our core.
