Job Description
The Role
As the first Security hire at Nous Research, you'll build and own security end-to-end across our infrastructure, products, and enterprise deployments. Nous builds open-source AI language models and agents, including Hermes Agent, which is used by consumers and Fortune 500 enterprises across multi-tenant SaaS, dedicated VPC, self-hosted, and air-gapped environments.
This is a hands-on-keyboard role for someone who wants to harden multi-cloud infrastructure, secure a novel agentic AI platform, and build the security foundation regulated enterprise customers demand. You'll be the person focused full-time on protecting the company while helping the rest of the team continue shipping quickly.

Own production security across a multi-cloud footprint spanning AWS, GCP, Azure, and Vercel.
-
Secure multi-tenant SaaS, dedicated VPC, self-hosted Kubernetes, and air-gapped deployments.
-
Secure the Hermes Agent platform across sandboxing, kernel-level file system and network isolation, agent identity, credential controls, egress controls, and trace integrity.
-
Own SOC 2 technical controls, evidence collection, remediation, and ongoing readiness.
-
Harden identity and access management, including SSO and SAML consolidation, least-privilege access reviews, 2FA, and BYOD policies.

Interest in securing agentic AI systems and addressing emerging risks across agent identity, tool permissions, prompt injection, and data provenance.
-
Ability to work effectively in a high-velocity, open-source-native engineering culture.
