For this, you could use for example https://flyte.org/, if you have platform engineers that could set it up for you. But I don't think their website makes a good job of explaining what it is and what it does.
What I try to do, is understand who created the platform, and understand the environment of that company. Then that will give you a better idea of whether it makes sense for you or not.
It also supports - gpu allocation, spot instances and collaboration across multiple users. I do not think it is a wrong choice if you feel your complexity will grow.
PS. I am a maintainer of the project
