Simulation Code Developer

Focused Energy is a fusion energy startup with the goal of generating unlimited clean energy to responsibly meet future global demand. With the use and commercialization of laserinduced inertial fusion clean and highly efficient power generation technology is coming within reach suitable to ensure a secure and scalable future energy supply.

We are seeking for a skilled and driven Simulation Code Developer to join our team and help us shape the future of energy. This person will perform radiation hydrodynamic simulations with existing codes to optimize the target design and will develop a 3D radiation hydrodynamic code to simulate the implosion and ignition of cryogenic deuteriumtritium fuel capsules. Your work will help to achieve a robust implosion target point design for Focused Energys inertial fusion energy (IFE) power plant.

In this role you will be part of the Science team at Focused Energy which is responsible for achieving a robust implosion target point design for Focused Energys firstofakind (FOAK) fusion power plant and for the precursor fusion pilot plant (FPP). An important part of the teams work are simulations to assess the likelihood of ignition for different designs that balance the threat from laserplasma instabilities and from hydrodynamic instabilities. The work will lead to a selfconsistent ignition target design for the FPP and the FOAK that optimize the mitigation of hydrodynamic instabilities and the mitigation of laserplasma instabilities during the implosion phase by considering different options in target manufacturing and in the laser design.

What youll do:

• Develop and maintain 3D radiation hydrodynamic codes: This includes creating new code from scratch and improving existing codes for simulating implosion and ignition of cryogenic deuteriumtritium fuel capsules. This also involves adding new physics packages to existing codes.

• Perform radiation hydrodynamic simulations: Conduct simulations using existing codes to optimize target design and analyze the results. This includes assessing the likelihood of ignition for different designs balancing laserplasma and hydrodynamic instabilities.

• Lead code development projects: Take ownership of code development working closely with the Science team to ensure the code is highperforming reliable and meets requirements. This involves adapting the system as needed.

• Collaborate on code validation: Work with experimental teams to compare simulation results with experimental data ensuring the accuracy and reliability of the codes. This includes identifying discrepancies and refining the code accordingly.

• Optimize code performance: Improve code efficiency and speed through parallelization and other optimization techniques to enable largescale simulations.

• Document code and simulation results: Maintain clear and comprehensive documentation of the code its features and simulation results. Prepare reports and presentations to communicate findings to the team.

• Stay current with the latest research: Keep uptodate with the latest developments in inertial fusion energy and simulation techniques integrating new knowledge into the code development process.

• Contribute to code testing and debugging: Develop and execute test cases to ensure code functionality and identify and fix bugs.

• Participate in code review: Review code written by other team members to ensure quality and adherence to coding standards.
