What I'm looking for

I’m looking to lead information security end-to-end in a remote-first product company—owning identity, secure SDLC, cloud posture, and compliance—so teams ship fast and safely with measurable outcomes like fewer incidents and faster audit prep.

I’m a Head of Information Security with over 15 years in IT (9 in security), focused on helping remote-first SaaS teams protect highly sensitive data while moving fast. This year, we hit 100% SSO+MFA, started shifting to passwordless, cut cloud misconfiguration fixes from two weeks to two days, and halved audit prep time (80 to 40 hrs).

I direct a cross-domain security team and own a ~$1M departmental budget (headcount, SaaS vendor spend, and advisory), while orchestrating talent acquisition for senior roles. I embedded security work into delivery—raising on-time security commitments from ~60% to ~85% with a JSM/Slack-integrated helpdesk—and I lead product security and observability initiatives, including a UEBA anomaly analysis feature and a unified log pipeline.

My approach is practical and measurable: I embedded SAST/SCA/DAST and defect triage into CI/CD to improve high-risk closure within SLA from 57% to 93%, reducing cloud misconfiguration MTTR from 14 to 2 days and sustaining zero critical cloud incidents for four consecutive quarters. I also implement policy-as-code with automated evidence capture, maintaining SOC 2, ISO 27001, and GDPR posture alongside comprehensive IR runbooks and continuous monitoring.
