About Us Alembic is the pioneering Causal AI platform. We help the world's largest enterprises move past correlation to prove what actually drives business outcomes — the question marketing and growth teams have never been able to answer with confidence. Fortune 100 companies including Nvidia, Delta Air Lines, and Mars use Alembic to make multimillion-dollar decisions on trusted, causal evidence. We're backed by a $145M Series B from WndrCo (founded by Jeffrey Katzenberg), Jensen Huang, Joe Montana, Prysm Capital, and Accenture. Our models run on our own NVIDIA DGX SuperPOD built on Grace Blackwell infrastructure — one of the fastest private supercomputers in the world. (We've melted GPUs getting here.) About the Role We're looking for a lead-level Security Engineer and Architect to own system, network, and host security end-to-end for a rapidly growing on-prem, Kubernetes-based AI factory. This is a hands-on, high-impact role reporting directly to our CTO/CISO and working side-by-side with Technical Operations, Corp IT, Platform Engineering, and our scientific teams. It's not a compliance seat that exists to satisfy published controls — it's the chance to shape our security posture from the ground up, secure high-value client data, and build the team and tooling to do it. Two things make this role distinctive. First, Alembic is "Default to Open" by design: security here must respect that maximum information sharing is basic to how we operate, while still protecting customer data and the IP — patents and trade secrets — our applied-science work generates. Balancing those is the core intellectual challenge of the job. Second, we're an AI-first company that uses many kinds of AI across everything we do; deciding which AIs operate in which containers is one of the more interesting problems you'll own. What You'll Do - Design and implement security controls across all environments — network segmentation and firewalling, IDS/IPS, and traffic analysis on our on-prem Kubernetes platform. - Build and enforce host security: EDR, kernel telemetry, hardening, and baseline implementation across the fleet. - Own identity and access — AuthN/AuthZ, RBAC, and service identity — grounded in OIDC, SAML, and mTLS. - Stand up incident-detection pipelines (SIEM, metrics, endpoint telemetry) tuned to surface high-signal threats over noise, and lead incident response end to end: triage, containment, recovery, root-cause analysis, and forensics. - Keep the focus on enablement over restriction — effective security, not compliance for its own sake — while balancing IP protection, customer-data protection, and broad internal information sharing. - Partner with Legal and the CISO to obtain the compliance certifications we need and to answer customer questions about the security of our systems; hire and mentor as the security function grows. What Will Help You Succeed - 8+ years in security engineering, infrastructure, or related roles. - Strong Linux system security and networking (SSH certificates, directory-based authentication) and strong Kubernetes security (RBAC, tenant isolation, admission control). - Real experience securing on-prem environments, not only public cloud. - A proven track record leading real-world incidents, with familiarity with attacker techniques (lateral movement, persistence, exfiltration) and hands-on depth in EDR, IDS/IPS, and SIEM. - Strong command of OIDC, SAML, mTLS, and cryptography-based storage security. - Comfort writing code, automation, and tooling in Python or similar, plus configuration management via IaC (Terraform, Ansible). - The judgment to distinguish high-signal threats from noise, make pragmatic tradeoffs in a fast-moving company, and communicate effectively with technical stakeholders. Nice to have: high-performance or distributed-compute experience (HPC, GPU clusters); identity-aware proxies or zero-trust architectures; offensive security (red teaming, e
