Chemistry Engineer


Our client, a Pioneering Nuclear start-up is looking for a Chemistry Engineer to join their UK Engineering team to work closely with the Process Design Team and the Materials R&D team to ensure a robust chemistry justification specification for all fluid systems in their LFR design. Our exciting client is a clean and safe nuclear technology company looking to disrupt the energy space by developing designs based on innovative Lead-cooled Fast Reactors (LFRs).

This is an exciting opportunity to join an ambitious nuclear company, joining the project at an early stage and actively contributing to the design of the next generation of nuclear reactors.

The role will be a mix of working from home and office based in Manchester or Gloucester, with regular travel to the other offices in Turin and Lyon.

  • Permanent position
  • Hybrid working
  • Share Incentive opportunities.

Main duties/role and responsibilities

  • Development of chemistry specifications for all fluid systems in the LFR (including molten lead system, gaseous systems and water/steam systems).
  • Development of the chemistry and materials sampling and monitoring requirements, as well as the on-site laboratory requirements, for the LFR.
  • Provision of specialist chemistry support to the Process Design Team relating to chemical injection systems and chemical purification systems (including filtration and ion-exchange).
  • Identification of R&D needs relating to chemistry and materials.
  • Close collaborative working with the Materials R&D team in order to specify, design and implement chemistry test programs.
  • Analysis and interpretation of R&D results.
  • Provision of specialist chemistry support to the Safety and Licensing Team, supporting the overall development of the LFR safety case.
  • Collaborate with multi-disciplinary scientific and technology teams.
  • Coordinate assigned work with other technical personnel as directed.
  • Participates in and fosters a work environment that is based upon openness, trust, communication, teamwork, empowerment, innovation, and satisfaction.

Attributes/ Experience required.


  • Knowledge of water/steam chemistry, oxidation, corrosion, stress corrosion cracking mechanisms, and/or tribo-corrosion with temperature.
  • Knowledge of chemistry purification techniques, including filtration and ion-exchange.
  • Knowledge of sampling and monitoring requirements and techniques for process fluid systems.
  • Knowledge of Heavy Liquid Metal and/or Molten Salt chemistry and associated oxidation/corrosion mechanisms is an advantage.
  • Ability to participate in team meetings and prepare technical presentations.
  • Experience in power plant chemistry, particularly related to the water/steam cycle (the “secondary circuit”) is an advantage.
  • Experience in a nuclear or other highly regulated environment and good understanding of safety aspects would be a definite advantage.


  • Degree in Nuclear, Materials, Chemical/Electrochemical Science.
  • Master’s or PhD is considered an added value

Residential Status and Location

  • Right to work in UK
  • Minimum 3 days in the Manchester/Gloucester office
  • Willing to travel regularly to Italian/French sites.
