Company

Perplexity is building cybersecurity products powered by agents that perform security work across application security, offensive testing, cloud security, and detection and response.

What you will do

• Build cybersecurity products from zero to one across application security, penetration testing, offensive security, cloud security, and detection and response.
• Develop agents that review code, find vulnerabilities, test applications and infrastructure, assess cloud configurations, investigate threats, and validate or apply fixes.
• Build multi-tenant services, data pipelines, and secure execution environments for customer code, cloud accounts, and telemetry.
• Integrate with source control, CI/CD, cloud providers, identity providers, security tools, ticketing systems, and chat platforms.
• Deliver APIs, dashboards, onboarding, and workflows for security and engineering teams while maintaining strong tenant isolation, least privilege, and safe handling of customer secrets and data.
• Define quality metrics such as finding accuracy, false-positive rate, exploitability, time to fix, and cost; work with design partners and customers to prioritize future products.

Requirements

• 4+ years of experience as a software engineer building production systems, including meaningful experience with security products, security data platforms, or security engineering involving substantial software development.
• Proficiency in at least one major programming language, such as Python, Go, TypeScript, or Rust, and experience owning production services end to end.
• Hands-on depth in at least one security domain: application security, penetration testing or offensive security, cloud security, or detection and response.
• Experience integrating source control, CI/CD, cloud provider APIs, identity providers, scanners, SIEMs, or other security- and developer-relevant systems.
• Familiarity with cloud infrastructure, preferably AWS, and secure multi-tenant SaaS.
• Comfort working directly with customers and shipping pragmatic improvements quickly in an ambiguous, early-stage product area.

Nice to have

• Experience building LLM-powered agents, evaluation frameworks, or tool-using automation for security or other high-stakes domains.
• Experience at a security product company or on an internal security platform at scale.

Culture & Benefits

• Work directly with security engineers, design partners, and enterprise customers.
• Build products grounded in real codebases, environments, attackers, and customer workflows.
• Equity is included in the compensation package.
