Nuclear Waste Chemist
Blykalla is scaling quickly in order to industrialize our small modular reactor (SMR) concept. If you are passionate about nuclear technology and want to make a significant impact, join us!
Do you thrive on analyzing complex material systems and translating chemistry into engineering strategy?
We’re looking for a Nuclear Waste Chemist to lead technical evaluations that support purification strategies, minimize radioactive waste, and guide Blykalla’s backend design decisions for its first-of-a-kind lead-cooled SMR. You’ll work across simulation, literature review, and partner coordination to make sure our waste systems are safe, scalable, and future-ready.
What we do at Blykalla
Blykalla is a Swedish deep-tech company at the forefront of the nuclear industry, pioneering the development of small modular reactors that provide clean, safe, and reliable energy. Thanks to lead-cooling, we achieve high safety in a very compact format, allowing for a simple and cost-effective design that can be mass-produced. Our unique reactor design will provide safe and green baseload energy that perfectly complements solar and wind power.
What you’ll get to do
You’ll lead the analytical and coordination aspects of Blykalla’s nuclear waste chemistry— contributing to feasibility studies, system designs, and future licensing strategies.
Analyze and evaluate expected waste streams (solid and liquid) based on reactor design and operating scenarios
Identify opportunities to reduce low-, intermediate-, and high-level waste volumes through system-level decisions, purification strategies, or material choices
Assess treatment options for lead coolant contaminated with fission products or actinides, using available data and partner input
Review and compare chemical separation methods (e.g., silver or actinide separation) for potential use in Blykalla’s systems
Coordinate with research institutions, vendors, and industrial partners performing experimental work on waste and coolant treatment
Contribute to writing technical reports and feasibility studies for licensing, design decisions, and strategic planning
Serve as the internal reference point for chemistry-related questions across the waste lifecycle
Where this role can take you
This is a unique opportunity to shape early how nuclear waste is managed in one of Europe’s most advanced nuclear start-ups. As you grow into the role, you’ll gain visibility across disciplines and contribute directly to the design and deployment of a first-of-a-kind reactor system. Over time, you may:
Influence key design decisions that affect how waste is generated, treated, and classified
Take the lead in building our technical strategy for coolant purification and waste conditioning
Work with national labs, vendors, and regulators to turn ideas into practical, accepted solutions
Become Blykalla’s go-to expert on radiochemical behavior, material treatment, and long-term waste strategy
Help define how future SMRs manage their materials and legacy—not just safely, but intelligently and sustainably
Who you are
You’re analytical, curious, and motivated by impact. You enjoy turning complex data, research, and system behavior into practical insight. You’re excited by the idea of building something from the ground up—especially in a field as consequential as nuclear waste. You work well across disciplines, communicate clearly, and take pride in structured thinking. You’re not in the lab yourself, but you’re fully at home working with those who are—connecting chemistry to design, safety, and strategy. Above all, you want to be part of a team solving hard problems for the long term.
Qualifications
- Degree in chemistry, radiochemistry, chemical engineering, or a related field
- Experience analyzing or evaluating chemical processes, purification methods, or waste treatment strategies
- Familiarity with radioactive or hazardous waste challenges in nuclear, energy, or industrial systems
- Strong analytical and communication skills—able to structure data, write clearly, and collaborate across teams
- Fluent in English; Swedish is a plus
- Eligible to work in Sweden
The following will be considered a plus:
Knowledge of lead chemistry, actinide behavior, or fission product separation
Experience working with national labs, vendors, or technical facilities performing experimental work
Exposure to waste classification frameworks or backend system planning
Experience writing technical reports for feasibility studies, internal strategy, or regulatory purposes
If you are not sure that you are 100% qualified but are up to the challenge, we encourage you to apply.
Location
The position is based in Stockholm, with travel to partner labs and industrial sites as needed.

About Blykalla
Blykalla is Sweden's only SMR vendor, commercializing lead-cooled fast reactors for industrial use. Based on 20+ years of research, their SEALER technology is a compact 55 MWe unit designed to offer a safe, efficient, and scalable power solution. With a strong foundation within Sweden, Blykalla is well positioned to deliver Europe's first advanced SMR, providing reliable and sustainable baseload energy to power AI and clean industries.
Backed by partners such as Uniper, ABB, KSB, Höganäs, and the Royal Institute of Technology, Blykalla has secured close to EUR 50 million in funding, including a SEK 99 million grant from the Swedish Energy Agency and a EUR 17 million investment from the EU. The company plans to complete its first SEALER reactor by 2030 and begin serial production in the 2030s. By 2050, their technology could generate up to 500 TWh of clean electricity annually, cutting global CO₂ emissions by 0.5 gigatons each year.
