Software Engineer (Agent Infra)

About the role

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.

Responsibilities

• Lead the systems that orchestrate our research agents
• Ship systems with real failure modes: leases, retries, idempotency, blast-radius reasoning
• Work in TypeScript and C++ but care more about engineering depth than specific languages
• Ship 800-line refactors when 30 lines would do
• Fix what's broken regardless of whose code it is
• Articulate where AI-native workflow tools help and where they don't

Requirements

• Three to six years of engineering experience
• AI agents in production: not prototypes
• Distributed systems chops: real failure modes
• Cloud fluency: production depth in at least one of AWS, Azure, or GCP

Qualifications

• No security background required. We'll teach you the domain

Skills

• Taste for small, reversible changes
• High agency: read a plan doc and ship

Benefits

• Compensation Range: $200K - $300K
