    Senior Product Security Engineer

    Remote in Brazil or LATAM

    The Role

    We're hiring a Senior Product Security Engineer to work hand-in-hand with developers to secure the product across its entire lifecycle. You'll be the person who makes our platform defensible — through design reviews, threat modeling, hands-on penetration testing, and secure-coding partnership — and you'll do it as a collaborator who helps engineers ship securely, not a gatekeeper who slows them down.

    This role partners closely with product engineering and platform engineering teams.

    What You'll Do

    • Partner directly with developers to secure the product across the Software Development Life Cycle (SDLC), embedding security early rather than bolting it on at the end.

    • Lead security design and architecture reviews, and run threat modeling on new features and services.

    • Perform hands-on penetration testing of web applications and Application Programming Interfaces (APIs), and translate findings into clear, prioritized, fixable work.

    • Conduct secure code reviews and help define secure-coding standards and security acceptance criteria.

    • Operate and tune Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and dependency / supply-chain scanning, and triage what they surface.

    • Help engineers understand the "why" behind findings so the same class of issue doesn't recur.

    • Contribute security evidence and rigor to our compliance posture (System and Organization Controls 2, or SOC 2, ISO 27001, etc.).

    What You'll Need (Required)

    • A strong track record in product or application security — you've measurably made real products more secure.

    • Hands-on penetration testing experience against web applications and APIs.

    • Deep understanding of how modern web applications work — single-page front ends, APIs, authentication and authorization (for example, OAuth 2.0 / OpenID Connect), sessions, and the common ways each is attacked (for example, the Open Worldwide Application Security Project, or OWASP, Top 10).

    • Experience running security design reviews and threat modeling.

    • Solid understanding of the SDLC and how to embed security into it.

    • Strong communication skills — you work directly with developers and can explain risk in terms they'll act on.

    Nice to Have

    • Familiarity with open-source security tooling (for example, OWASP ZAP and Burp Suite Community Edition for testing, Semgrep for SAST, Trivy or Grype for dependency and container scanning, Nuclei for templated scanning).

    • A relevant offensive-security certification (for example, Offensive Security Certified Professional, or OSCP).

    • Cloud security experience (Amazon Web Services, Microsoft Azure, or Google Cloud Platform) and container / Kubernetes security.

    • Experience supporting a SOC 2, International Organization for Standardization (ISO) 27001, or similar program.

    • Background in enterprise or regulated environments where deployment security is non-negotiable.

    What Success Looks Like (First 90 Days)

    • You've reviewed the product's architecture and threat surface and identified the highest-priority security risks.

    • A repeatable, lightweight process exists for security design reviews on new work.

    • Security findings have a clear triage-to-remediation path, and developers know how to engage you early.
