Grow With Us

We are seeking a Security Engineer who is, at heart, a builder. In this role, you won't just be running scans or writing policies; you will be writing code, fixing vulnerabilities, and architecting secure infrastructure alongside our engineering teams.

You will act as the primary "Blue Team" lead, defending Company against threats while collaborating with external Red Team communities to stay sharp. Your scope is holistic: you will cover Application Security, Infrastructure Security, and Corporate Security , ensuring that security is baked into our DNA, not bolted on at the end.

• This is a full-time, hybrid role requiring presence 3 days a week in either San Francisco or Menlo Park office to foster close collaboration with cross-functional teams.
• Day in the Life
• Application Security (AppSec)
• Embed yourself in the software development lifecycle (SDLC). Perform code reviews and architectural analysis for new features in Node.js and Ruby on Rails .
• Work side-by-side with software engineers to locate, triage, and fix security vulnerabilities (e.g., XSS, SQLi, IDOR) directly in the codebase.
• Build and maintain automated security tooling (SAST/DAST) in our CI/CD pipelines.
• Secure AI/ML integrations and APIs, including protection against prompt injection, model poisoning, and data exfiltration through AI interfaces
• Review and secure implementations of large language models (LLMs) and other AI services used in the platform
• Infrastructure & Cloud Security
• Harden our cloud infrastructure (AWS/GCP/Azure) using Infrastructure-as-Code (Terraform/CloudFormation).
• Design and implement secure networking, IAM policies, and container security (Kubernetes/Docker).
• Monitor system logs and alerts to detect and respond to anomalies in real-time.
• Blue Teaming & Incident Response
• Act as the internal Blue Team lead. Collaborate with external Red Teams and bug bounty researchers to understand the latest attack vectors.
• Translate Red Team findings into concrete engineering tasks and defensive measures.
• Lead incident response simulations (Tabletops) and actual response efforts during security events.
• Corporate Security
• Oversee internal company security posture, including endpoint protection, identity management (Okta/SSO), and zero-trust networking access.
• Conduct security training for employees to foster a culture of security awareness.
• Design security architecture supporting multi-state and multi-jurisdiction data residency requirements
• Collaborate with legal and other teams on data breach notification procedures and requirements across multiple jurisdictions
• Maintain security documentation for SOC 2 Type II audits and other compliance frameworks
• Who You Are
• Technical Qualifications
• Engineering Background: You have a strong background in software engineering. You are comfortable reading and writing production-level code, specifically in Node.js and Ruby on Rails .
• Holistic Security Experience: 3+ years of experience covering the "Security Trinity": Software Security, Infrastructure Security, and Corporate/IT Security . Experience in SaaS, fintech, or HR technology environments strongly preferred.
• Vulnerability Remediation: Proven track record of not just finding bugs, but working with engineers to solve them. You understand how to implement fixes without breaking functionality.
• Cloud Native: Deep experience securing modern cloud environments (AWS preferred) and containerized applications.

HR/Payroll Security Understanding: Familiarity with security challenges specific to HR and payroll systems, including protection of sensitive employee data (PII, SSN, wage information), multi-tenant architecture security, and regulatory compliance requirements for employment data.

AI/ML Security: Understanding of AI security principles including model security, training data protection, prompt injection vulnerabilities, AI-powered threat detection, and emerging AI-specific attack vectors. Familiarity with AI governance frameworks and responsible AI practices.

• Collaborative & Mindset
• Red Team Aware, Blue Team Focused: You actively follow Red Team communities (CTFs, DefCon, Bug Bounties) to understand the attacker mindset, but your passion lies in building the defense (Blue Team) to stop them.
• Empathy for Engineers: You understand that "perfect security" shouldn't destroy developer velocity. You focus on guardrails, not gates.
• Communication: Ability to explain complex security risks to non-technical stakeholders and provide clear technical guidance to developers.
• Bonus Points
• Active participation in Bug Bounty programs or CTF competitions.
• Experience with compliance frameworks (SOC 2, ISO 27001, HIPAA).
• Certifications such as OSCP (Offensive Security Certified Professional) or CISSP.
• Experience securing Open APIs.
• Experience with multi-tenant SaaS security architecture
• Background in fintech, HR technology, or payroll systems security
• Familiarity with state-specific data residency and privacy requirements
• Knowledge of AI security frameworks
