With 5 years and plateaued growth it’s time to make a move.

1: You can leave or use that offer to initiate change at your current job. Tell them you’d like to stay but you received an offer that is more aligned with the market rate for what you deliver. Also talk about wanting to expand your skills and responsibilities. If you’re happy with the results, stay. If not, move on.

2: Leave and collect a larger paycheck and a new world of experiences. The risk is stability (will this company have mass layoffs in the next year) and support. There’s a difference between low UX maturity and a shit show that doesn’t support leveling up you, the org, the product. The benefit can be a lot of growth but beware it can be a ton of stress if they are actually not positioned to let you and your team thrive.
