- Conduct threat modeling and security design reviews for new features, services, and architectural changes—partnering with product and platform engineers early in the design phase.
- Perform secure code reviews and provide actionable feedback, focusing on authentication, authorization, input handling, secrets management, and data protection.
- Deploy and maintain security tooling across the development lifecycle—SAST, SCA, DAST, secret scanning, IaC scanning, and CI/CD security guardrails.
- Support best practices to adopt secure-by-default libraries, frameworks, paved-road patterns, and developer guidance to reduce classes of vulnerabilities across the codebase.
- Partner with platform engineering on infrastructure and environment security—including AWS resource hardening, Terraform-managed infrastructure reviews, network segmentation, and environment isolation improvements.
- Contribute to incident response for security events: investigation, root cause analysis, and post-incident hardening.
- Drive vulnerability triage and prioritization across teams, tracking remediation against targets and reporting metrics.
- Partner with sales and legal responding to customer and vendor questionnaires, RFP security sections, and trust-and-safety inquiries.
- Support SOC 2, ISO 27001, PCI 4.0, and other compliance audit cycles by gathering evidence, documenting controls, and coordinating with auditors.
- Monitor and respond to alerts from endpoint, cloud, and application security tools; manage vulnerability tracking and remediation follow-up across the environment.
- Execute recurring user access reviews, IAM hygiene tasks, and RBAC maintenance required by compliance frameworks.
- Maintain and improve security runbooks, process documentation, and operational playbooks—building automation where possible to reduce manual burden using AI-assisted development tools.
Experience
- 5+ years of experience in security engineering, security operations, or a related role that combined both.
- Hands-on experience with at least one of SOC 2, ISO 27001, or PCI compliance audit cycles.
- Strong application security fundamentals: threat modeling, secure code review, and familiarity with common vulnerability classes (OWASP Top 10, CWE).
- Experience with security tooling across the development lifecycle: SAST, SCA, DAST, secret scanning, or IaC scanning.
- Working knowledge of AWS infrastructure and services, including IAM, VPC networking, and security configurations.
- Familiarity with infrastructure-as-code (Terraform preferred) and CI/CD pipeline security.
- Proficiency in Python and comfort reading code across backend services.
- Strong written communication skills for writing audit documentation, security questionnaire responses, policy documents, and runbooks.
- Comfort using AI-assisted development tools (e.g., Claude Code, Copilot, or similar) to write scripts, build automations, and accelerate documentation.
Salary and Perks
Pay range: $180K - $220K
- Competitive equity grants.
- 100% employer-paid benefits.
- Flexibility of being fully remote.
- 401k match up to 4% for US-based full-time team members.
