The following skills are worth having and are portable between jobs.
DevSecOps - Notice the 'Sec' very important. Focus on github actions.
Kubernetes - Be able to deploy containers you created with your DevSecOps pipeline.
Infra structure as Code - In particular Pulumi. Works well with Kubernetes.
Rust - Makes you a better programmer.
