> Hinoki Security is seeking a Software Engineer to own core platform infrastructure, including AI agents, data modeling, and verification surfaces. The role requires 3-6 years of experience in distributed systems and cloud technologies, with a focus on building autonomous AI-native workflows.

## Job description

## ABOUT HINOKI SECURITY

AI is collapsing the cost of offense. What used to require a skilled exploit developer can increasingly be automated, and defenders are still working from tooling that was designed two decades ago: tools that produce endless lists of findings without telling anyone what actually matters or what to do about it.

Hinoki is building the AI-native platform that fixes this. We continuously map an enterprise's real exposure, figure out what is genuinely dangerous in the customer's specific environment, and drive the remediation through to verified resolution. Old scanners produce lists. We produce fixes.

We're backed by Andreessen Horowitz and led by a second-time security founder, most recently from Google. The platform is already in production at Fortune 500 enterprises.

## THE ROLE

This is a critical engineering hire with broad ownership over core platform infrastructure. Depending on your strengths, you may lead the systems that orchestrate our research agents, the data layer that models a customer's environment in real time, the verification surfaces that prove our agents' work is correct before anything reaches a customer, or the reporting surfaces where our hard-work translates to CISO-level impact.

## ENGINEERING CULTURE

We have a high bar for taste and quality. There's too much AI slop in the world, and we would like to see less of it.

Every decision the product makes has provenance: why we believe what we believe, who owns it, what evidence supports the next action. We invest heavily in the internal frameworks that let our humans, our coding agents, and our production agents work fast while minimizing mistakes.

## WHAT WE'RE LOOKING FOR

Three to six years of engineering experience, plus:

- AI agents in production. Not prototypes. Real autonomous systems with multi-step reasoning, tool use, memory, evaluation, and failure handling.
- Distributed systems chops. You've shipped systems with real failure modes: leases, retries, idempotency, blast-radius reasoning.
- Cloud fluency. Production depth in at least one of AWS, Azure, or GCP.
- AI-native workflow. Claude Code, Codex, or Cursor is in your daily loop. You can articulate where these tools help and where they don't.
- High agency. You read a plan doc and ship. You don't wait for tickets. You fix what's broken regardless of whose code it is.
- Taste for small, reversible changes. You know when to extract a helper and when to keep code inline. You don't ship 800-line refactors when 30 lines would do.

We work in TypeScript and C++ but care more about engineering depth than specific languages. No security background required. We'll teach you the domain.

## About Hinoki Security

## Company Overview
- **One-liner**: Hinoki Security builds an AI-native continuous vulnerability scanning and remediation platform that maps enterprise exposure, identifies genuine risks, and drives fixes to verified resolution.
- **Entity Type**: Private, venture-backed (Series undisclosed)
- **Headquarters**: San Francisco, California, USA
- **Founded**: Not publicly available
- **Founders**: Not publicly disclosed (led by a second-time security founder, most recently from Google)

## Core Business
- **Industries**: Cybersecurity (vulnerability management, exposure management, AI-powered security)
- **Target Customers**: B2B enterprise, including Fortune 500 companies
- **Mission / Purpose**: Collapse the cost of defense by using AI to replace legacy scanners that produce endless lists with an outcome-driven platform that actually fixes problems.

## Products & Services
- **Hinoki Platform**: A self-driving exposure management platform that scans for CVEs across cloud and on-premises, AI-pentests applications for business logic vulnerabilities, prioritizes findings using existing enterprise data, and automates remediation until verified. Combines continuous scanning, AI agent‑driven validation, and patching into a unified SaaS platform.

## Market Standing
- **Valuation / Funding**: Not publicly disclosed; backed by **Andreessen Horowitz** (a16z).
- **Key Metric**: **Annual Recurring Revenue (ARR)** – Not publicly available. **Total Funding** – Not publicly available.
- **Notable Investors / Partners**: Andreessen Horowitz (lead investor); platform in production at Fortune 500 enterprises.
- **Growth Signals**: Active hiring for multiple engineering roles (Agent Core Infra, Web Platform); job postings reference rapid deployment with enterprise customers; strong investor backing from a top-tier VC.

## Competitive Advantages
- **AI-native, not bolt-on**: The entire platform is built around autonomous AI agents – old scanners produce lists, Hinoki produces fixed problems.
- **Outcome-driven agents**: Multi-step reasoning, tool use, memory, and evaluation ensure remediation is verified, not just flagged.
- **Provenance and transparency**: Every decision has a clear audit trail (why the agent believes something, who owns it, what evidence supports the next action).
- **Continuous mapping**: Real-time visibility into exposure across cloud and on-prem environments, not periodic snapshots.
- **Taste & quality focus**: Deliberate avoidance of “AI slop” – high bar for engineering rigor and product quality.

## Strategic Focus
- **Current priorities**: Scale the platform to handle more enterprise environments; deepen agent orchestration and verification capabilities; expand the frontend product surface for analysts and security engineers.
- **Direction for growth**: Continue replacing legacy vulnerability management tools with an AI-driven, outcome‑oriented approach; build out the data layer that models customer environments in real time.

## Why Work Here
- **Engineering culture**: High agency, small reversible changes, AI-native workflow (Claude Code, Codex, Cursor daily). “You read a plan doc and ship. You don’t wait for tickets.”
- **Tech stack**: TypeScript and C++ (depth valued over specific languages); distributed systems; cloud fluency (AWS, Azure, GCP).
- **Learning opportunity**: No security background required – the company teaches the domain. Engineers get exposure to AI agents, autonomous systems, and real‑world infrastructure at scale.
- **Work mode**: Onsite/hybrid in San Francisco (job listings indicate “Onsite” or “Hybrid”).
- **Compensation**: Estimated $185,000–$300,000/year depending on role (Web Platform ~$185k, Agent Core Infra ~$200k–$300k).
- **Culture notes**: “We have a high bar for taste and quality. There’s too much AI slop in the world, and we would like to see less of it.”
