Seaborg Technologies is a start-up on the forefront of advanced and innovative nuclear reactor technology working to provide abundant, affordable and sustainable energy to the world. We have grown to become the leading molten salt reactor start-up outside of North America with an international team of 20 employees from four continents. We are actively developing the design for our Compact Molten Salt Reactor, alongside licensing and experimental validation activities of key safety and performance claims, and are currently planning a multi-million salt lab to accelerate these efforts. We are engaged with multiple stakeholders in the growing advanced reactor supply chain, primarily in East Asia.


Our success is entirely due to our brilliant and passionate team of employees and experienced advisers - a team we are currently in the process of expanding with more world-class talent determined to create positive change in the world.


We are hiring a Licensing and Qualification Manager to plan and lead the licensing of the CMSR. The successful candidate will develop and execute strategies for licensing a next-generation nuclear reactor that differs radically from conventional technologies in changing regulatory frameworks. This includes identifying, planning and performing R&D to substantiate design hypotheses, preparing argumentation and documentation for regulatory stakeholders, qualifying novel systems, structures and components (SSC), and more. The position will collaborate closely with our safety, engineering, reactor physics and chemistry departments to ensure that all relevant licensing considerations are included in the technical development work. Additional interfaces will be maintained with business development to coordinate customer expectations and partner capabilities with ongoing and future licensing efforts. International travelling should be expected.

Given appropriate experience and satisfactory performance, the hired candidate will be considered for VP of Regulatory Affairs.


Seaborg employees must be able to act proactively and independently to perform a wide variety of functions that do not always correlate with experience or expertise (such as writing job advertisements). That being said, the advertised position is expected to include at least some of the following responsibilities and tasks:

  • Be responsible for the licensing of a first-of-a-kind, next-generation nuclear reactor that differs radically from conventional reactors, and that is poised to revolutionise energy markets;

  • Function as primary interface between Seaborg and regulatory stakeholders;

  • Develop and execute long-term licensing strategies and plans;

  • Oversee, coordinate and adapt the licensing of a novel nuclear reactor concept within a changing regulatory framework;

  • Work with reactor physics, chemistry and engineering departments to identify, plan and execute R&D campaigns needed in the licensing process;

  • Systematically search for appropriate standards and classes for molten salt-bearing SSC, perform gap analyses, and prepare qualifications strategies where needed;

  • Interface with a wide range of global stakeholders, particularly from regulatory authorities;

  • Where necessary, prepare schedules, budgets and project plans for qualifying novel and non-standard SSC;

  • Establish collaborations and partnerships for performing cost-efficient validation of key security and safety claims, including irradiation work;

  • Represent Seaborg at meetings and conferences that aim at modernising current regulatory frameworks;

  • Support and guide the formulation and substantiation of the CMSR safety and security cases;

  • Support and guide the reactor development process, providing regulatory insights;

  • Train new employees and interns from around the world;

  • Support IP development and acquisition activities.


  • Desire to positively change the world by shaping the energy landscape of tomorrow;

  • Demonstrated ability to creatively and diligently approach and solve challenging tasks within time and budgetary constraints;

  • Considerable (5+ years) experience with licensing and/or qualification activities in nuclear, oil & gas or other relevant energy industries;

  • Experience leading or importantly participating in the successful licensing of nuclear, oil & gas or other relevant energy installation;

  • Experience formulating and substantiating safety cases for energy installations;

  • Experience interfacing with technical departments to plan and execute R&D activities in support of licensing or qualification activities;

  • Experience with ISO or NQA quality assurance standards;

  • Experience with relevant standards and codes from e.g. ASME and IEEE;

  • Familiarity with nuclear safety and security concepts;

  • Management/leadership experience;

  • Experience with South East Asian regulatory authorities preferred;

  • Team player with effective communication and interpersonal skills, including fluency in English;

  • Ability to travel by plane and communicate outside of normal working hours when necessary.

At Seaborg we strongly value the combination of relevant experience, talent and personality traits that align with our team and overarching vision for a sustainable future. We therefore encourage applications from diverse backgrounds and are prepared to mould the job description to accommodate exceptionally well-aligned candidates.


While our team is still small, our ambitions are not. Becoming a part of Seaborg presents a unique possibility to importantly impact and define the global energy landscape of tomorrow. We know that new ideas and influences are key to challenge the status quo and strive for continuous improvement, and so new hires can expect to importantly contribute to shaping both the technology and the future of the company.

We want to play an active role in enabling the personal and professional development of all employees so that they can evolve and grow to take on changing tasks and responsibilities. To give room for this development, we practice high work flexibility in an informal, merit-based environment without strict hierarchies. With time, we expect every employee to become an invaluable part of Seaborg and our success, and we underpin this expectation by offering all new employees stock options in the company.


We are based in Denmark, a country known for its high quality of life and extensive social welfare system. That means free health care and education, generous vacation arrangements, progressive maternity and paternity leave provisions, etc. More on this at


Our office is situated centrally in Copenhagen - a young and vibrant European capital on the Øresund coast with a thriving expat community and world-leading bicycle infrastructure.
