R&D Chemist

Engineer R&D - Microfluidics & Instrumentation at Gnothis AB

Valley Recruitment AB

Gnothis AB is seeking for a hands-on engineer who enjoys building experimental systems in a laboratory environment. The role combines microfluidics integration, instrument prototyping, and Python-based automation. This is a permanent position based at our HQ, located at the campus of Stockholm University (Stockholm, Sweden). Gnothis, founded in 2015 and supported by highly innovative industrial professionals and technology developers, is on a mission to develop a new frontier for single molecule DNA sequencing; to break the mold on how sequencing is used as a clinical tool for the diagnosis of complex diseases. Gnothis technology integrates a wide range of cutting-edge sciences ranging from nanotechnology, photophysics, optics, surface chemistry, biochemistry and computational science. Since we have taken significant steps forward and now need to solve the remaining crucial challenges before commercialization; for the right person this is a unique opportunity to become a valuable member, to use your “think-outside-the box” mentality with aim to develop a new world-class technology platform! Our instrumentation, software and analysis team currently consists of four engineers and we are now expanding the team as we scale development of the system. The work is primarily on-site and very practical, involving both hardware integration and control software development. The position is part of a multidisciplinary team developing a prototype DNA sequencing instrument combining microscopy, microfluidics, nanofabrication and advanced data analysis. Initial Project The first major task will be to design and integrate a microfluidics subsystem into our existing microscope prototype – to plan, test, order and add already commercially available components to a final prototype. This includes selecting and integrating a commercial microfluidics system (e.g. Elveflow or similar), designing a custom sample chip holder and fluid interface, integrating control into an existing Python control software, and establishing practical operation and cleaning procedures. The work is supported by a biochemistry team, but we are seeking for the right candidate who can make confident engineering decisions based on previous hands-on experiences connected to eg. microfluidics and laboratory automation. Responsibilities Mechanically integrate new devices into a prototype life-science instrument. The initial focus is on liquid sample handling, such as flow and temperature control. Develop Python control and automation software, starting from existing vendor SDKs. Design simple mechanical parts (CAD / 3D printing) Hands-on prototyping and debugging in the lab Method development for instrument performance evaluation and self-calibration. Over time the role will involve increasing focus on automation and device control software. Candidate Profile For you to enjoy performing expected activities, and being a valuable member in an ambitious and innovative team; we think you are an engineer with a strong creative mindset and with strong previous experience building/developing scientific or laboratory instrumentation. This role suits someone who enjoys experimental prototyping in a small startup environment. The candidate should be comfortable collaborating in a multidisciplinary research environment consisting of engineering, software, biochemistry and nanofabrication experts. Relevant backgrounds and skills include: Master of Science and/or Ph.D. educational background – ideally combined with a relevant Life Science focus. Practical experience with microfluidics systems Python programming for hardware control Comfortable with hands-on lab engineering (CAD, electronics, prototyping) Microscopy / Optics / Imaging Lab automation / Liquid handling Mechatronics / Robotics A recent Ph.D. with strong hands-on instrument development experience could also be a good fit for this position. Gnothis offer a creative environment focused on technology and product development, a competitive compensation package and plenty of room for self-development as the company expands. This is a permanent position (not consultant assignment). If above sounds like an exciting opportunity and you would like to hear more, do not hesitate and submit your application and we will get back to you!

Nuclear Waste Chemist

Blykalla AB

Blykalla is scaling rapidly to industrialize our next-generation small modular reactor (SMR) technology. If you are passionate about nuclear technology and want to make a real impact on the future of clean energy, we’d love to hear from you. Do you thrive on solving complex chemical and material challenges through hands-on experimentation and analytical thinking? We are looking for a Nuclear Waste Chemist - an experimentalist role to help develop Blykalla’s backend chemistry and waste management strategies for our lead-cooled SMR technology. In this role, you will combine experimental R&D, technical analysis, and cross-functional collaboration to support areas such as waste minimization, coolant purification, material reuse, spent nuclear fuel (SNF) handling and backend system development. This is an opportunity to help build both the technical foundations and laboratory capabilities for one of Europe’s most advanced nuclear startups. What we do at Blykalla Blykalla is developing the next generation of nuclear technology through advanced Small Modular Reactors (SMRs) based on innovative fuel, materials, and reactor designs. As Sweden’s leading SMR developer, our mission is to decarbonize industry and provide safe, scalable, and sustainable energy solutions. Our reactors use uranium nitride fuel and lead coolant, creating unique opportunities and challenges across fuel cycle chemistry, coolant purification, and waste management. What You'll Do You will play a key role in building Blykalla’s experimental capabilities related to backend systems and nuclear waste management. Your responsibilities include: Help establish and develop Blykalla’s in-house chemistry laboratory and experimental capabilities. Design, plan, and perform experiments related to waste treatment, coolant purification, and material handling. Troubleshoot experimental systems, identify suitable analytical methods, and independently drive investigations forward. Contribute to technical reports, feasibility studies, licensing documentation, and strategic decision-making. Investigate opportunities to reduce low-, intermediate-, and high-level waste volumes through purification strategies, system design, and material choices. Analyze and evaluate expected waste streams, both solid and liquid, based on reactor operating conditions and system design. Evaluate treatment, purification, recycling, and waste management methods for Pb coolant, activated materials, and SNF, including contamination control and backend management considerations. Work closely with national laboratories, industrial partners, and regulators to turn research into deployable solutions. Act as an internal technical resource for chemistry-related questions across the waste lifecycle and backend systems.
