Internship CAD Mechanical Engineering
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!
Are you a creative and detail-oriented engineering student passionate about transforming ideas into tangible designs? Blykalla is looking for a CAD and Mechanical Design Intern to support the development of our next-generation nuclear technology through 3D modeling and prototyping.
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
As a CAD and Mechanical Design Intern, you will gain experience from working hands-on with our engineering team to model, visualize, and prototype key components of our reactor systems. Your work will support both technical development and communication of Blykalla’s technology.
- Develop and refine SolidWorks CAD models for mechanical components and assemblies.
- Design 3D-printable prototypes for demonstrations and testing.
- Participate in the full prototyping process, from concept to printed part.
- Collaborate with mechanical and nuclear engineers to ensure designs meet functional and safety requirements.
- Contribute to improving CAD file management and design documentation workflows.
- (Optionally) explore FEA or thermal modeling if aligned with your background and interests.
Who you are
You are a student in Mechanical Engineering, Product Development, or a related field — for example, through a university program or a LIA internship.
You enjoy bringing designs to life and take pride in precision, creativity, and teamwork.
We believe you have:
- Basic knowledge of SolidWorks.
- Experience or interest in 3D printing.
- A curious mindset and attention to detail.
- The ability to collaborate effectively in a technical environment.
- (Bonus) You’re applying together with a fellow student to collaborate and support each other during the internship
What You’ll Gain
During your internship, you’ll gain hands-on experience in an innovative technological environment, insights into next-generation nuclear energy, and practical skills in CAD modeling, prototyping, and engineering visualization — all of which will strengthen your engineering foundation.

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.
