Blykalla is developing next-generation nuclear technology through the SEALER program, requiring structured and evidence-based
technology maturation across multiple concurrent development streams.
We are looking for a Senior Systems Engineer who will define and evolve the framework for Technology Readiness Levels (TRL),
Technology Readiness Assessments (TRA), and Technology Maturation Planning across the portfolio.
This role ensures that SEALER technologies progress from concept to deployable system in a coherent, traceable, and strategically
well-aligned way.
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 Senior Systems Engineer – Verification & Validation, you will define and support how technologies mature across the SEALER
portfolio. You will establish the framework that connects Technology Readiness, verification and validation approaches, and
product development milestones into a coherent and traceable system. Your responsibilities will include:
Technology Maturation & Readiness
Verification & Validation Strategy
Verification, Validation & Qualification Governance
You will play a key role in shaping how SEALER technologies mature from early-stage concepts to fleet deployment. As the V&V
organization grows, this role can evolve into functional leadership of Advanced Validation Engineers or broader portfolio-level
technical leadership within SEALER’s development.
You are a systems-oriented engineer who enjoys working at the intersection of technology development, validation, and structured
product maturation. You bring technical depth, a thoughtful and structured approach, and the ability to understand and translate
engineering topics into clear and actionable maturation pathways across a portfolio.
