Security Researcher
About The Position
Pi is building an agentic product security platform for teams that need to secure software at the speed they build it. Modern development is accelerating, but security knowledge is still scattered across code, tickets, documents, incidents, reviews, and the people who remember why decisions were made. Pi turns that context into institutional security memory, helping teams triage faster, remediate in context, prevent repeat vulnerability classes, and embed security guardrails where engineering work already happens. We are building for a future where security is not a blocker at the end of the development process. It is part of how software gets designed, reviewed, shipped, and improved. Pi was recognized on Fast Company's 2026 Next Big Things in Tech list and covered by Forbes!
Requirements
- 8+ years in security research, vulnerability analysis, or applied security engineering.
- Experience in an early stage or 0 to 1 environment. Comfortable with ambiguity, shipping without a big org behind you, and changing direction when the data says so.
- Track record of turning research into shipped features, tools, or detections in production.
- Deep expertise in modern application stacks (microservices, containers, cloud platforms).
- Strong programming ability in at least one modern language (Python, Go, TypeScript). Comfortable writing production quality code.
- Experience designing experiments, building datasets or benchmarks, and measuring quality quantitatively.
- Hands on experience applying LLMs to real problems, whether evaluation, prompting, fine tuning, or agentic systems, or a demonstrated ability to get there fast.
- A history of discovering serious vulnerabilities (CVEs welcome) and responsible disclosure.
- Ability to explain a complex attack and its real impact clearly to engineers, executives, and customers.
- Permanent authorization to work in the US.
- Willingness to work onsite in San Francisco five days a week.
Nice To Haves
- Research that went public and mattered. Publications, disclosures, or talks that changed how people think about a problem, not just filled a slot at a conference.
- A product built at a startup. Something that shipped, that real users depended on, where you can point at your fingerprints.
- Novel ways of putting LLMs or agents to work inside real engineering or security workflows, beyond demos and prompt wrappers.
- A healthy disrespect for "that's how we've always done it," and a track record of building the better way.
Responsibilities
- Identify where new approaches can meaningfully beat the state of the art in vulnerability detection, triage, and remediation, then decide what we pursue and what we kill.
- Build proofs of concept for new detection and remediation techniques, validate them against real world code and data, and carry the winners through to production with engineering.
- Design the datasets, benchmarks, and evaluation pipelines that measure precision, coverage, and false positive rates.
- Deep research into modern attack vectors across cloud (AWS/GCP), containers, microservices, APIs, AI generated code, and LLM applications.
- Develop the internal corpus of vulnerabilities, exploit patterns, and remediation strategies the platform learns from.
- Contribute to what we publish, where we speak, and the credibility the company earns in the security community.
Benefits
- Meaningful equity in Pi.Security
- Medical, dental, and vision coverage for you and your family, starting the 1st of the month after you join.
- Flexible Spending Accounts (FSAs) for health and dependent care
- Commuter benefits
- Unlimited PTO
- 401(k)
- Health and wellness stipend
- Lunch allowance on in-office days
