Understand what the cut is pricing
A pay cut is an employer discounting for ramp-up time and hiring risk, not enforcing a rule about domain changes. Every piece of evidence that shortens the ramp โ projects in the new stack, on-call in the new system, work you already shipped โ reduces the discount they believe they need to apply.
Keep the transferable half visible
The strongest domain switchers are not beginners; they bring something the new team lacks. Domain knowledge, production experience, scale exposure, compliance familiarity, stakeholder skill. Lead with what carries over, then present the new skills as what you are adding rather than as what you are still learning.
Sequence so you never test the market cold
Internal transfers, hybrid roles and projects straddling both domains let you gain experience while your salary stays anchored. By the time you interview externally you are a candidate with experience in the domain rather than a career changer, and the discount conversation never begins.
