I have a set of questions to answer your scenario:
1) Are you working in a start up / MNC ?
2) how many years of IT experience do you have ?
A very generic answer to your question would be, start learning testing (manual & automation) & start looking for a job change internally first. Work for atleast an year in the same position to get good perspective from testing side of all the projects you have worked so far & this gives you a good boost.
clear CSTE etc certifications to get better view of testing & more opportunities to get that role internally / externally.
