About Harden

Harden is the enterprise security and governance platform for AI-built apps. Every AI-generated application ships with the same gaps — hardcoded secrets, missing auth, uncontrolled egress, no audit trail. Harden closes them all automatically: build-time SAST and SCA scanning, auto-remediation, runtime enforcement, and one-page approval reports that become the gate in CI/CD.

Our BYOC (Bring Your Own Cloud) architecture deploys entirely inside the customer's VPC — sensitive data never leaves their perimeter. We're a lean, venture-backed team combining AI/ML research leadership from Google DeepMind and Amazon with product leadership from Verkada and AWS, building the security layer that makes enterprise AI adoption safe and scalable.

Founding Enterprise Security Engineer

Onsite preferred, but remote considered for strong candidates in US or CanadaFull-time$150,000–$250,000 + equity

Harden is an opinionated DevSecOps layer that secures AI-generated applications by automatically injecting identity controls, network boundaries, and compliance instrumentation prior to deployment. Our focus is on the application and infrastructure layer surrounding AI systems, working alongside foundation model providers who advance model-level safety. We value engineers who can think adversarially about real-world deployments and translate that into resilient, production-grade systems. The ideal candidate blends enterprise security engineering, backend platform development, and solution architecture. This role requires deep experience with core SaaS security primitives such as SSO, SCIM, and RBAC, along with network isolation and SOC 2, ISO 27001, etc aligned controls. You will embed these capabilities directly into our automated pipeline and articulate their value in clear, executive-level terms for CISOs.

Founding AI Engineer

Remote (US) or Hybrid (SF Bay Area)Full-time$120,000–$250,000 + equity

You'll work across the stack to design, train, and deploy RL-driven optimization loops for AI agents. At Harden, those loops help inspect AI-generated applications, reason about security gaps, generate reliable fixes, and evaluate whether applications are ready for enterprise deployment. You need to be deeply technical, hands-on, and comfortable moving between research, ML engineering, security engineering, and production systems (APIs, infra, SLAs). This role sits at the intersection of LLM systems, security engineering, and production software. The goal is not to build demos; it is to ship AI-assisted hardening systems that enterprises can trust inside real CI/CD and BYOC environments.

Founding AI Infrastructure Engineer

Remote (US) or Hybrid (SF Bay Area)Full-time$150,000–$250,000 + equity

You'll own the engineering foundations for taking AI-powered workflows (including agentic systems) from prototype to reliable production. At Harden, that means building the infrastructure that analyzes, transforms, and governs AI-built applications in customer-controlled environments. This is a high-ownership, hands-on role spanning distributed systems, ML systems, Kubernetes/cloud infrastructure, performance engineering, and enterprise-ready platform design. You'll build core platform capabilities (execution/runtime, data/model pipelines, APIs, observability, scaling) and ensure the system is fast, resilient, secure, and easy to integrate into a customer's existing stack, including VPCs, CI/CD pipelines, SIEM, identity, ticketing, and compliance workflows.
