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 assessments - Proven judgment under ambiguity — able to rank findings honestly and defend the ranking - CS/CE degree or equivalent hands‑on experience Preferred Qualifications - Hands‑on ISO 27001 experience — operating an ISMS, recertification, surveillance audits,



internal audit programmes, Statement of Applicability, risk treatment - SOC 2 experience in practice — producing evidence, answering auditor requests, remediating findings against a real deadline - Any exposure to AI governance or ISO 42001 — AI risk assessment, model inventory, AI lifecycle controls, the EU AI Act - Infrastructure as code at scale (Pulumi primarily, Terraform secondarily — deep Terraform experience transfers fine) - Multi‑account cloud organization experience: landing zones, org‑level policy guardrails, centralized logging, cross‑account access patterns - Identity provider and endpoint management at scale (Google Workspace or Microsoft 365, SSO/SAML/OIDC, MDM and device compliance tooling) - Cloud security tooling experience (CSPM, SAST/SCA, vulnerability management platforms), including their false‑positive rates - Container orchestration on ECS, EKS, or Kubernetes - Observability: metrics, logs, traces, and the judgment to instrument what will matter later - Experience across both AWS and GCP, including workload identity federation - Cloud cost awareness — you notice when spend and value diverge - Startup or high‑growth experience building process rather than following one What Success Looks Like - You can own ambiguous, high‑stakes security and compliance problems end-to-end - Controls you build hold automatically as the company scales — you design for guardrails that fail closed, not recurring manual verification - You bring strong technical judgment on tradeoffs between security rigor, velocity, and cost - You raise the bar for security rigor and operational discipline across the team - You help define what's next for the security program, not just execute what's known Why Join Nexxa.ai?
