Process system engineer
Your mission
You will be the work package lead of some systems in Thorizon Pioneer related to nuclear processes and as such responsible for all activities related to design those systems in Thorizon Pioneer design and safety case. In close collaboration with internal functions – thermohydraulics, neutronics, … - you will coordinate studies you need and move the design of your system from a concept to a concrete object. Reporting to the Pioneer Project Director and Pioneer Architect, you will ensure the integration of your system within the overall reactor and manage the interface with the other systems. You will manage potential collaboration with subcontractors on design first and then on realization. In collaboration with the Safety team, you will be accountable for ensuring your system is safe and defend your case towards the regulators.
You have strong experience in process engineering, with a focus on the nuclear environment as a strong plus. You know how to design process flow diagrams and define requirements for associated equipment. You are skilled in sizing safe and high-performance processes, including establishing process schemes, performing material balance calculations, sizing equipment, and drafting technical specifications. You also know how to design P&IDs and author operating procedures or functional notes to ensure seamless transition from concept to realization.
You are able to self define your weekly routine. You have a strong spirit of team effort and as such able to maneuver in cross-functional teams. You have a high level of communication skills and stakeholder management.
This role is based in Amsterdam, Netherlands or in Lyon, France.
In This Role You Will
At Thorizon, we’re a passionate team spread across Amsterdam and Lyon, all working together to develop new nuclear power solutions. We design and create frontier technology for Molten Salt Reactors (MSRs).
Our purpose is to accelerate the availability of clean energy and help solve the climate crisis.
We are in the development phase and aim to solidify our design through analyses, simulations, experiments, prototyping, and partnerships. At Thorizon, we believe a strongly coupled multidisciplinary technology development requires a culture of full openness and transparency. That’s why we foster values like unity, communication, and support to ensure we grow together as a team while achieving our purpose.

In This Role You Will
- Define,validateand verify (functional) requirements forspecific systems related to processofThorizonPioneer,optimizethe design to deliver on those requirements, and manage trade-offs in the design envelope. (e.g., reliability, performance, lifetime, costs) while continuously ensuring maximum safetyand prepare for the realization of this system
- Develop and review Process Flow Diagrams (PFDs) to define the overall process architecture and material/energy balances.
- Design andvalidatePiping and Instrumentation Diagrams (P&IDs) to ensureaccuraterepresentation of equipment, instrumentation, and control logic for safe and efficient operations.
- Work in cross-functionalteam in Pioneer project(typically a project-based team of ~3-6 engineers from different disciplines such as nuclear engineering, core physics, thermal hydraulics, chemistry)
- Conduct engineering work foryourworkpackage(e.g., componentand system design, computermodelsand analyses to simulate safety and performance)
- Initiate projects with our expert engineers that support you with analyses, validation,verificationand qualification.
- Select,qualifyand manage external contractors that support you in your mission.
- Deliver system documentation, prepare design reviews, and ensure system integration.
- Build documentation and presentation to enable licensing discussion with safety authorities.
- Support program management by coordinating meetings, communicating with external partners, and leading specific projects.
- Participate in meetings with regulators with the aim of defending in-house positions and contribute tomaintainingan active dialogue with regulators (in particular ASNR, ANVS and FANC)
