Senior Backend Engineer

I am a hands-on engineer who has worked on backends(Go, Python), mobile (Android), and frontends (React, Vue). I have strong familiarity with cloud technologies (GCP - preferred, AWS - basic, Azure - basic). And with CI/CD technologies (Jenkins -> Travis CI -> Circle CI -> GitHub Actions + Google Cloud Build). I am looking for a hands-on senior engineering (Chief Architect/Principal/Staff) role, primarily, focused on backend. Ideally, a full-time role, but open to part-time as well. Strong preference for engineering autonomy.
