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.

Overall Purpose
The Head of Nuclear Engineering & Safety is responsible for building and leading Blykalla’s nuclear engineering organization. The role ensures that all nuclear safety cases, licensing activities, and core nuclear analyses are performed to the highest international standards, in close collaboration with external partners, universities, and the regulator. This role works closely with the CTO to align nuclear development with safety and licensing requirements, and plays a key part in positioning Blykalla as a world leader in lead-cooled SMR technology.
Key Responsibilities
Team Development & Leadership
Build and lead a high-performing Nuclear Engineering & Safety team.
Define roles, responsibilities, and long-term capabilities within nuclear safety, licensing, and analysis.
Mentor and empower team members, ensuring professional growth and delivery capacity.

Licensing & Regulatory Interface
Own and coordinate all nuclear engineering work related to licensing.
Act as the main technical counterpart towards the regulator.
Oversee safety analysis reports (SAR), safety classification, QA, and technical submissions.

Nuclear Safety & Safety Basis
Set frameworks for deterministic and probabilistic safety analyses (DBA, DEC, PSA).
Ensure methodologies for risk assessments, FMEA, and safety case development.
Define and maintain the overall safety basis of the reactor design.
Nuclear Analysis & Design Authority
Oversee reactor physics calculations, core simulations, and nuclear safety margins performed by the team and external partners.
Provide design authority for the nuclear scope (fuel, core design, reactivity control, nuclear safety systems).
Lead nuclear design reviews and approvals, ensuring compliance and integration with overall plant design.

Partnerships & Networks
Collaborate with industrial partners, universities, and research institutes to accelerate nuclear development.
Represent Blykalla in international nuclear safety forums and networks.
Build strong external collaborations to support the development of a world-leading nuclear engineering capability.

Who you are
10+ years of experience as a Senior leader with extensive experience in nuclear safety, licensing, and engineering.
Proven track record of working with regulators and delivering safety cases.
Deep knowledge of safety analysis methodologies (deterministic and probabilistic), reactor physics, and nuclear systems.
Strong leadership skills – you inspire, coach, and grow high-performing teams.
Collaborative and strategic, able to navigate the interface between technology development and regulatory requirements.
Fluent in English; Swedish is a plus.
