Chief Engineer - Mechanical Engineering
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 is a perfect complement to solar and wind power.
What you’ll get to do
As a Chief Engineer, you have one of the key positions of the Engineering team. Within the engineering team, you guide a group of engineers that develops components and systems for the nuclear island, from their conceptual design to industrial manufacturing. Because you are our subject matter expert for all aspects of mechanical design and engineering, you also support other streams of product development with your expertise.
More specifically, your work includes:
Maturing our product. You get your hands dirty with the team and take the product to a high technology readiness level by designing, prototyping, and testing ideas and solutions.
Solving technical issues. You identify and analyse potential issues with our products and apply corrective actions to such issues.
Meeting requirements. You ensure that components and systems meet all criteria for e.g. usability, cost, reliability, manufacturability, maintenance, and safety
Communicating with conviction. You document and communicate the work and results of the team in technical reports and communicate these to stakeholders with and without a technical background.
Providing expertise and support. You apply your experience and skill-sets to other engineering teams that need it for their own product development processes.
Growing team competence. You train and mentor junior engineers and designers in your own team and outside the team.
Who you are
For some years now, you have worked with developing industrial machines or components of larger machines, operating in complex environments and having low error tolerance and high requirements regarding reliability. Your technical judgment on the operability and reliability of machinery is based on practical experience in addition to a sound academic education on the matter. You are sufficiently skilled in all matters of mechanical engineering to define and delegate work, and to guide those junior to you to conduct such work efficiently. We think you have experience from the process industry (i.e. energy, oil, pulp & paper, nuclear, etc.) where you have dealt with e.g. piping & vessel design, Heath Exchanger design, other component design.
As a person, you are result-oriented and treat obstacles as a temporary set-back on your way to finding solutions. You are a good communicator and thrive when explaining and sharing knowledge of the design to others – both in terms of products, systems, and people.
Requirements:
Bachelor's or Master's degree in Mechanical Engineering or a related field.
Proven experience within an engineering team, preferably in a product development environment.
In-depth knowledge and expertise in mechanical design and engineering.
Strong analytical and problem-solving skills.
Experience in designing, prototyping, and testing mechanical and structural components and systems.
Familiarity with nuclear industry regulations and standards is a plus.
Excellent communication skills, both written and verbal, with the ability to convey technical information to non-technical stakeholders.
Demonstrated ability to lead and motivate others to achieve project goals.
Strong organizational and time management skills to effectively prioritize and manage multiple tasks.
Continuous learning mindset and a passion for staying updated with emerging technologies and trends in mechanical engineering.
Fluent in English, spoken and written
Fluency in Swedish is a plus
The role includes interactions with many internal and external stakeholders.
If you are not sure that you are 100% qualified but are up to the challenge, we encourage you to apply.
Location
This position is for our office in Stockholm.
So, what do you think?
We are proud to foster an inclusive workplace free from discrimination. We strongly believe that diversity of experience, perspectives, and background will lead to a better environment for our employees and a better product. This is something we value deeply and we encourage everyone to be a part of changing the way the world thinks about power supply!

About Blykalla- Leadcold
Blykalla is a Swedish deep-tech company founded in 2013 by Janne Wallenius, Peter Szakalos and Jesper Ejenstam as a spin-off from the Royal Institute of Technology in Stockholm, where Janne Wallenius carried out research on design and safety analysis on lead-cooled reactor systems since 1996.
We develop and build lead-cooled small modular reactors (SMRs) to deliver safe, scalable and carbon-free baseload power supply. 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 is a perfect complement to solar and wind power.
We are taking leading research to industrialisation and working together with global utilities and partners like Uniper and OKG to deliver the first research reactor in Oskarshamn, Sweden.
