My suggestion would be to move to a higher level of abstraction, change the way which you view the system.

Maybe becoming full stack? Maybe understanding the industry a little deeper? Maybe analyzing your company's competitors better? That would increase your value for the business (a bit of overlap with product management though). Assuming you can now deliver the expected tech part more easily, that's what I'd do.

As for me, I've moved to a permanent product management position.
