Nuclear HVAC & Ventilation Engineer

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!

We are seeking an experienced HVAC and Ventilation System Engineer to lead the design and development of safety-critical ventilation systems for nuclear facilities. You will work within one of our engineering teams in a multicultural and multidisciplinary stimulating environment, where you will be responsible for establishing the complete design framework—from deriving top-level requirements from international codes and standards through basic and detailed design phases.

This role requires deep expertise in translating regulatory guidelines (IAEA, SSM, and other nuclear codes) into actionable system requirements while applying rigorous systems engineering principles to ensure safety, reliability, and regulatory compliance.

What we do at Blykalla

Blykalla is developing the next generation of nuclear technology with our Small Modular Reactor (SMR) based on innovative fuel, materials, and reactor designs. As Sweden’s only SMR developer, we are on a mission to decarbonize industries and enable safe, scalable, and sustainable energy solutions. Our technology uses uranium nitride fuel and lead coolant, creating novel challenges and opportunities for the fuel cycle and supporting systems.

What you’ll get to do

As an HVAC and Ventilation System Engineer, you will play a key role in leading the design and integration of nuclear ventilation and HVAC systems, ensuring safety, reliability, and regulatory compliance throughout all design phases. You’ll collaborate with cross-functional teams and regulatory bodies to develop systems that meet the highest safety standards for nuclear facilities. Your key responsibilities would be:
