Security-focused Developer

I currently work as a Penetration Tester for a consultancy where I work on multiple different projects from web application testing, internal/external network assessments, Cloud Config Reviews, and Social Engineering. While I get some opportunities to build bespoke tooling for my colleagues I would like to make that my focus and get back to using my passion as a developer. A job where I could build security focused tooling/products would be amazing but am open to any dev position.
