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.
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 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
Define SEALER's TRL framework and facilitate Technology Readiness Assessments (TRA) across programs.
Identify critical technologies and characteristics that influence system maturity and risk.
Develop and maintain Technology Maturation Plans (TMP) together with system engineers and subject matter experts.
Verification & Validation Strategy
Define how analysis, inspection, testing, and demonstration activities contribute to structured TRL advancement.
Establish method selection and qualification approaches aligned with system architecture.
Coordinate maturation efforts and validation resources across concurrent SEALER development streams.
Verification, Validation & Qualification Governance
Integrate Technology Maturation Plans into the Integrated Product Development Roadmap (IPDR).
Ensure readiness progression aligns with stage-gates and V-model design milestones.
Support Design Verification Planning (DVP), maturation reviews, and structured progression between development phases.
Where This Role Can Take You
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.
Who You Are
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.
We are looking for someone who:
A relevant engineering degree (nuclear, aerospace, mechanical, systems engineering, or similar).
Experience with Technology / Manufacturing Readiness Levels (TRL / MRL), Technology Readiness Assessments (TRA), or similar readiness frameworks.
Background in systems engineering and structured product development.
Experience in (S-/D-) FMEAs and identifying critical technologies and defining structured maturation and design verification/validation plans (DVP&R).
Understanding of stage-gate models, concurrent engineering, and V-model development.
If you don't meet all of these requirements, we still encourage you to apply!
As a person:
You have the ability to structure complex topics and use analytical thinking.
You communicate well and can effectively speak across disciplines and programs.
Its beneficial with a background in nuclear, aerospace, or other highly regulated industries
Comfortable contributing in a dynamic and evolving development environment.
Location
The position is based in Stockholm, with travel to Oskarshamn and partners expected.
