Member of Technical Staff (Software Engineer, Cybersecurity Products) at Perplexity · LumiJobs

Responsibilities

Perplexity is building cybersecurity products where agents do the security work, not just assist with it. Our security team already runs agents on our own environment every day, across finding vulnerabilities, testing our defenses, securing our cloud, and responding to threats. Now we're turning that work into products for customers, and we expect those products to span application security, offensive testing, cloud security, detection and response, and areas we haven't picked yet.
We're looking for a hands-on Software Engineer to build these products end to end, from the security logic and agent workflows to the integrations and product surfaces customers use. You'll ship to design partners and enterprise customers quickly, and you'll work directly with the security engineers who do this work internally, so what we build is grounded in real codebases, real environments, and real attackers.
Build security products from zero to one across domains such as application security, penetration testing and offensive security, cloud security, and detection and response.
Build agents that do real security work: review code and find vulnerabilities, test applications and infrastructure like an attacker, assess cloud configurations, and investigate threats, then validate findings and recommend or apply fixes.
Build the systems underneath: multi-tenant services, data pipelines, and secure execution environments that run against customer code, cloud accounts, and telemetry.
Build integrations with the tools customers already use: source control and CI/CD, cloud providers, identity providers, security tools, ticketing, and chat.
Ship the product surfaces customers use: APIs, dashboards, onboarding, and workflows that fit how security and engineering teams actually work.
Hold the product to the same standard we hold ourselves: strong tenant isolation, least privilege, safe handling of customer secrets and data, and tight controls on any agent that acts in a customer environment.
Define how we measure quality (finding accuracy, false positive rate, exploitability, time to fix, cost) and use it to drive improvements.
Work directly with design partners and customers, and help decide which security problems we should build products for next.
