Hands-on experience with container orchestration and schedulers such as Kubernetes or SLURM is essential.
Candidates should be comfortable profiling performance, optimizing I/O, and automating workflows.
A self-starter attitude, low-ego, collaborative spirit, and high energy are important traits for this role.
