About the role

Nexxa is building the best AI systems for heavy industries — enabling machines, systems, and operations to think, decide, and act autonomously across manufacturing, large-scale infrastructure, logistics, and legacy environments. Our mission is to translate deep technical breakthroughs into operational reality, solving some of the hardest systems-level problems in industry. ABOUT THE ROLE Selling autonomous systems into manufacturing, infrastructure, and logistics means our customers audit us before they trust us — security and compliance are a precondition for deploying our platform, not a function beside it. We hold SOC 2 Type 2 and ISO 27001, and we're moving toward more certifications because governing autonomous industrial systems responsibly is a commercial requirement in our market. You'll own our certification programs and the security and infrastructure underneath them — across our multi-account AWS organization, GCP footprint, and internal engineering platform. This role covers our own corporate and cloud environments, not customer plant-floor or control-system security. This role is ideal for candidates who want real, ongoing ownership of a security function, including standing up and running one of the industry's first AI management systems, at a company where trust and compliance directly determine whether customers deploy the platform at all. WHAT YOU'LL DO - Own the compliance calendar across SOC 2 Type 2 and ISO 27001 — evidence collection, access and vendor reviews, control monitoring, internal audit, management review, policy refresh, and audit readiness - Triage security findings across cloud posture, code scanning, dependencies, and secrets, and drive remediation to closure - Remediate what you triage directly in infrastructure as code, IAM policy, and pipeline configuration - Administer identity and access across cloud and SaaS, including SSO/federation, least-privilege roles, and the joiner/mover/leaver lifecycle - Support internal IT operations — endpoint fleet and device compliance, SaaS and license administration, asset inventory, support requests — while keeping the human cost of them flat as the company grows - Serve as the working interface to external auditors, our certification body, and customer security and procurement reviews - Build controls into infrastructure so they hold automatically, replacing manual verification with guardrails that fail closed - Harden CI/CD and the software supply chain — build identity, artifact provenance, dependency and secret hygiene - Debug production issues across cloud infrastructure, containers, and networking, and write the postmortem that keeps the fix from being forgotten - Produce documentation others rely on: runbooks, control narratives, architecture notes, postmortems REQUIRED QUALIFICATIONS - Professional experience in security engineering, infrastructure/platform engineering, or a closely related technical role — broad competence across security, networking, and operating systems, with real depth in at least one - Deep hands-on experience with: - Security fundamentals — trust boundaries and blast radius, authentication vs. authorization, least privilege, secrets handling, and judging real-world exploitability of findings - Networking — diagnosing connectivity issues across routing, firewalls/security groups, DNS, TLS termination, and proxies; comfortable with VPN/private connectivity and packet captures - Linux operating systems — processes, filesystems, permissions, systemd, resource limits, log analysis, and how containers relate to the host - Cloud infrastructure — hands-on with AWS or GCP beyond the console: IAM, networking, compute, and their failure modes - Strong scripting/automation skills (Python, Bash, Go, or similar) — recurring manual work gets scripted away, not tracked by hand - Strong writing ability: control narratives, runbooks, postmortems, audit responses, risk asse
