Role transition, regaining hands on skills

I’m looking for some guidance as I prepare for a role transition.

Background:

For the past few years, I’ve been working as a Software Architect. My responsibilities have primarily involved reviewing and critiquing design documents, providing architectural guidance, and supporting other staff engineers in their execution. The role has been valuable for building broad perspective, but it hasn’t carried much direct accountability for delivery. Hands-on work has been quite limited, and I realize I’ve drifted away from the practice of designing and building solutions end-to-end myself.

Context:

I’m about to move into a Staff Engineer role(different company) in about a month.

Concern:

I feel that my solution design skills have atrophied. I’m comfortable reviewing others’ proposals and spotting gaps, but I struggle when starting from a blank page. I want to rebuild confidence in designing systems and making concrete technical decisions.

If you’ve been through a similar shift—or coached someone who has—I’d love to hear what helped you or your colleagues succeed.
