About the Role
We are hiring a Director of Platform and Product Security to lead the security of Nscale’s core infrastructure platform and the software and services built on top of it. This is a hands-on engineering leadership role reporting directly to the CISO and working closely with Platform Engineering, Infrastructure, SRE, and product development teams. You will own two complementary disciplines: protecting our Kubernetes-based, multi-tenant AI cloud platform and embedding strong product security practices into the software lifecycle. This role is critical to how Nscale operates AI infrastructure at scale. You will build and lead teams that ship practical security controls, ensuring security strengthens the platform without becoming a drag on performance or deployment velocity.
What you'll be doing
- Platform Security
- Own the security architecture and controls for Nscale’s Kubernetes-based infrastructure, including workload isolation, admission control, RBAC, runtime enforcement, and tenant boundary integrity.
- Secure customer production workloads by defining and strengthening controls at the boundary between Nscale’s infrastructure responsibilities and customer-managed workloads.
- Drive encryption standards and key management across platform services, covering data at rest, data in transit, and cryptographic practices across internal and customer-facing services.
- Lead cloud security posture management across environments through configuration baselines, IAM governance, automated guardrails, and continuous remediation.
- Supply Chain and Deployment Security
- Build and operate image integrity and supply chain security capabilities, including image signing, provenance verification, and base image governance.
- Embed security into deployment pipelines with security gates that support delivery speed rather than block it.
- Establish safe deployment practices and rollback mechanisms for issues identified during release or operation.
- Product Security
- Own the security of software built and deployed on the Nscale platform through threat modeling, secure design review, and early security requirements in the development lifecycle.
- Build and scale application security tooling, including SAST, SCA, DAST, and secrets detection, integrated into CI/CD.
- Strengthen service security across the platform, including authentication and authorization between services, API security, and secure communication patterns.
- Partner directly with engineering teams to identify, prioritize, and remediate vulnerabilities.
- AI-Assisted Development Governance
- Enable the safe use of AI coding tools across engineering teams.
- Define secure usage patterns for AI-assisted development workflows.
- Evaluate risks in AI-generated code, including insecure code generation patterns, prompt injection concerns, and over-reliance on AI review.
- Integrate security checks into AI-assisted development processes to support secure scale-up.
KPIs
- Kubernetes platform control coverage.
- Cloud security posture remediation.
- Application security tooling adoption in CI/CD.
- Vulnerability remediation with engineering teams.
About You
- 15+ years in security engineering, with at least 5 years in a leadership role managing security engineers across more than one domain.
- Deep hands-on experience designing and operating security controls for Kubernetes-orchestrated production infrastructure.
- Proven experience with admission control, RBAC, network policy, runtime security, workload isolation, and multi-tenant boundary enforcement.
- Strong understanding of securing platforms that run customer workloads you do not control, including shared responsibility boundaries.
- Experience owning product security or application security programs, including threat modeling, secure SDLC, and developer-facing security practices.
- Ability to design security controls with performance impact and deployment velocity in mind.
- Strong engineering orientation with the ability to engage directly on architecture, code, and tooling decisions.
- Experience securing workloads in multi-cloud environments across AWS, GCP, and/or Azure, including IAM, account governance, configuration management, and posture monitoring.
- Familiarity with the security implications of AI-assisted development, including prompt injection, insecure code generation, and over-reliance on AI review.
- Preferred experience in GPU, HPC, or AI workload environments, plus exposure to tools such as CSPM platforms, Sigstore, Cosign, Terraform, OPA Gatekeeper, Kyverno, Go, or Python.
