Application process
- Working within a collaborative team of software engineers and domain experts, you will contribute to the core control applications that govern more than 5,000 power converters across the accelerator complex.
- A central aspect of this role is the ownership and modernisation of a set of software classes that support accelerator operations.
- You will take responsibility for migrating these classes from the existing FGCDv1 and FESA architectures to the next-generation FGCDv2 framework.
- This work offers a unique opportunity to combine hands-on software development with framework evolution: as you migrate and modernize your assigned components, you will contribute directly to the refinement and completion of the FGCDv2 framework, helping shape its future direction based on practical experience and operational needs.
- Take ownership of software components throughout their lifecycle, including the migration of applications to the FGCDv2 framework.
- Contribute to the evolution of the FGCDv2 framework by identifying, implementing, and validating improvements based on practical experience.
- Support software architecture, code quality, and CI/CD practices to ensure reliable, scalable, and maintainable solutions.
- Collaborate closely with software engineers, equipment specialists, and operational teams to deliver robust control applications.
