A change of employer or substantial change in working conditions generally requires notifying the authorities and may require a new authorisation, since the permit is tied to the qualifying job.
The HQP permit is granted on the basis of a specific qualifying job with a specific employer. If you change employer, role or the essential conditions that supported your authorisation, this normally must be reported to the immigration authorities and may need a new or modified authorisation.
Do not assume you can switch jobs freely as you might in your home country. Before accepting a new offer, check whether the change is permitted under your current authorisation or whether a fresh application is needed to keep your status valid.
