SF OfficeFull-timePosted 1w ago
About the role
Security-focused role owning the isolation, identity, defenses, and governance across Hone's AI engines and single-tenant/customer-VPC deployments. You will design and operate security controls for long-running agents, manage credentials and permissions, defend against prompt injection and data exfiltration, and ensure auditable, trustworthy engine operations.
Responsibilities
- Isolation and network sandboxing for long-running agents: default-deny egress, scoped access, tenant isolation.
- Identity and credentials for engines: per-engine service identities, short-lived scoped credentials, and a broker so agents never hold raw secrets.
- Defenses against prompt injection, data exfiltration and tool misuse across untrusted inputs.
- Permissions and audit: RBAC, approval gates, and a full record of every action an engine takes and why.
- Security architecture for single-tenant and customer-VPC deployments.
- Internal AI tooling for detection, review and response, including agents that red-team our own engines.
Qualifications
- 2+ years of security engineering experience, or equivalent depth from research, CTFs, open source or your own projects
- Time at a fast-growing startup
- You've designed and built security systems from scratch, not just audited them
- You've secured production systems under real load and handled real incidents
- Strong fundamentals: cloud security, identity and access, networking, isolation, application security
- You use coding agents every day and still understand every line you ship
- You break and build things for fun because you genuinely care about how systems fail
