Lead Product Security and Compliance Engineer
BigHappy is looking for a Senior/Lead Product Security & Compliance Engineer to be the org's go-to authority on product security. Someone who can own the problem end-to-end rather than hand off findings and move on. This is a senior, largely independent role: you'll set the security standards our engineering teams work to, contribute to and maintain our SOC 2 compliance from control implementation through audit readiness, and build the tooling and culture that catches vulnerabilities before they ship.
- Candidates must be open to work within USA time zones EST/EDT and PST/PDT hours.
Own product security end-to-end. Identify vulnerabilities across the full stack: application code, third-party dependencies, APIs, and cloud/infrastructure configuration.
- Work directly with engineering teams to assist with fixing what you find
- Pairing on remediation, explaining root cause, and building their ability to catch similar issues themselves, not just filing reports over the wall.
- Contribute and maintain SOC 2 compliance : control implementation, evidence collection, audit readiness, and ongoing maintenance as controls evolve.
- Champion secure development practices org-wide.
- Secure SDLC, code review guidelines, threat modeling for new features, and security training/enablement for engineers.
- Select, set up, and manage the security tooling stack.
- SAST/DAST scanning, dependency and vulnerability scanning, secrets detection, and coordination of periodic penetration tests.
- Own security incident response
- Detection, triage, remediation, and blameless post-incident review, including the process itself, not just individual incidents.
- Own access control and data protection practices.
- Least-privilege access reviews, data classification, and encryption standards across systems.
- Track and report on security posture and compliance status to leadership, in terms non-security stakeholders can act on.
- Stay current on emerging threats, relevant CVEs, and evolving compliance requirements (SOC 2 today, maybe ISO 27001 as we scale) and translate that into concrete changes to our practices.
- Run vendor security assessments, maintain security policy documentation, and act as the primary point of contact for external auditors.
- Build a security-first culture across engineering. The goal is a trusted advisor teams want to loop in early, not a gatekeeper they route around.
Must-Have Skills
- 6+ years of experience in product/application security, including demonstrated ownership of a SOC 2 (or comparable) compliance.
- Either built from scratch or carried through multiple audit cycles.
- Strong understanding of common vulnerability classes (OWASP Top 10 and beyond), with hands-on experience finding and fixing them, not just reading scanner output.
- Experience embedding security into the SDLC and shifting developer behavior.
- Able to influence practices across teams without formal authority and without becoming a blocker to shipping.
- Familiarity with cloud security, AWS preferred to align with our infrastructure, and working knowledge of modern security tooling (SAST/DAST, SCA, secrets scanning).
- Hands-on ability to read, review and suggest fixes in production code in at least one backend language (Go, Node.js, Python or Java).
- Strong communication skills. This role works cross-functionally with engineering, operations, and leadership, and needs to translate technical risk into business terms auditors, customers, and executives can act on.
- Relevant certifications - CISSP, OSCP, CCSK, or similar.
- Experience with Go language, including Go-specific security tooling.
- Prior experience in a startup or scale-up environment, balancing security rigor against shipping speed.
- Experience with ad-tech, martech, or another high-throughput, latency-sensitive domain.
- Experience taking a company through ISO 27001 or a similar framework beyond SOC 2.
- Experience running or coordinating penetration testing engagements with external vendors.
Inclusive Culture & Collaborative Environment: Our workplace thrives on collaboration, inclusivity, and engagement. From cross-functional 1:1s to team building activities like movie outings, events, and office get-togethers, we ensure every team member feels connected, valued, and empowered to contribute meaningfully.
