HEAD OF ENGINEERING

Pi.Security · San Francisco, CA · Full-time · Onsite, 5 days a week

ABOUT PI.SECURITY

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 https://www.fastcompany.com/next-big-things-in-tech/list list and covered by Forbes https://www.forbes.com/sites/thomasbrewster/2026/06/10/elon-musk-favorite-hacker-launches-100-million-ai-cyber-startup/!

ABOUT THE ROLE

We're hiring our first Head of Engineering to help lead the technical build-out of Pi's platform at a pivotal, early stage. You'll report directly to our CEO/co-founder and work shoulder-to-shoulder with a small, high-caliber team (fewer than 10 engineers today) as we scale the org. This is a hands-on leadership role: part of the week you'll be writing and reviewing code and making architectural calls, and part of the week you'll be hiring, mentoring, and shaping how the engineering team works as it grows.

This role is based in our San Francisco office, five days a week. We build in person, alongside the founding team, and that is a deliberate choice.

WHAT YOU'LL DO

• Own execution of the engineering roadmap end to end, working closely with the CEO/co-founder on product and technical strategy.
• Stay hands-on — writing code, reviewing PRs, and making architecture and design decisions alongside the team, especially in the platform's core systems (codebase ingestion, root-cause analysis, remediation generation, and the Sloane assistant).
• Recruit, hire, and onboard Pi's next engineers, and put in place the processes, standards, and culture that let a small team move fast without breaking things.
• Set technical direction across the stack — backend services, AI/ML pipelines, integrations with customer developer workflows (source control, CI/CD, issue trackers) — balancing speed with the reliability and trust our security customers require.
• Partner cross-functionally with founders on customer-facing technical conversations, including with security and engineering leaders at our customers.
• Build engineering practices (testing, code review, on-call, incident response) that scale as the team and customer base grow, without over-engineering for a startup's current stage.
• Champion security and quality in our own engineering practices — as a securi

ing xAI, Notion, Navan, Lemonade, and Teramind, and it's available through AWS Marketplace and a strategic partnership with Bugcrowd.

Our founders have lived inside this problem. Guy Arazi was a security researcher at Microsoft, and Yoni Ramon led offensive security work at Tesla. You'll work closely with both.

We're early enough that every hire shapes the product, the team, and how we work. You'll build alongside a humble, passionate, ambitious, and genuinely fun team that cares deeply about what we're building and about our customers.

We hire for four things, and we work this way every day:

• Speed. Velocity over polish. Something impactful this week beats a perfect plan for next quarter.
• Depth. You go past the point of requirement. That is usually where the interesting part starts anyway.
• Curiosity. The people who do best here ask the thing everyone assumed was already answered.
• Ambition. We take on assumptions this industry accepts as given, and disprove them.

COMPENSATION & BENEFITS

The base salary range for this role in San Francisco is $245,000 - $339,000 per year. This is our good-faith estimate of what we expect to pay at hire. Where an offer lands depends on experience, skills, and level. Base salary is one part of total compensation, which also includes equity.
