What the job involves

• You're the person who keeps that platform fast, reliable, and secure
• As Director of DevOps, Security & IT, you'll own how jrni builds, runs, and protects its infrastructure — reporting directly to the CTO and leading three connected functions: DevOps & platform engineering first, then security & compliance, then IT
• Most of your week lives in cloud infrastructure, automation, and production reliability across AWS and GCP
• From there, you'll own the security program that keeps enterprise customers confident (ISO 27001, SOC 2), and the internal IT that keeps the company moving
• It's a rare full-stack operational remit with real ownership, a direct line to the CTO, and room to grow as we scale
• We'd love to hear from an automation-minded engineering leader who has run production SaaS at scale and wants to shape all three functions — not just keep the lights on
• Own and optimize jrni's production cloud infrastructure (AWS, GCP) for scale, reliability, performance, and cost
• Partner with Engineering / SRE on CI/CD, release management, and production stability
• Lead infrastructure-as-code and automation to streamline workflows and remove toil
• Own monitoring, alerting, and observability so issues get caught and resolved proactively
• Implement and test disaster recovery and business continuity plans
• Lead vulnerability management, patching, and hardening across the estate
• Set the direction for jrni's Information Security program against ISO 27001 and SOC 2
• Own and improve operational controls satisfying ISO 27001, SOC 2, GDPR, and other frameworks
• Own jrni's AI security policy and governance standards (aligned with NIST AI RMF and ISO 42001)
• Lead AI Operations — using AI to improve efficiency while governing AI systems for privacy and security risk
• Own security and operational incident response; run tabletop exercises; serve as incident commander for Sev-1/Sev-2 events; lead blameless post-incident reviews and track remediation to closure
• Coordinate breach notification with Legal and the DPO where applicable
• Maintain a risk register and lead periodic enterprise risk assessments
• Own third-party / vendor risk management — vendor reviews, DPAs, sub-processor oversight
• Partner with Legal and external auditors on audits, evidence collection, and certification renewals
• Build and support a culture of security awareness, data protection, and compliance, including training
• Oversee IAM across corporate (SSO, MFA, SCIM) and production (least-privilege, JIT access, break-glass), with access reviews and joiner/mover/leaver processes
• Manage corporate IT, endpoint management, and SaaS administration
• Improve processes for productivity, scalability, and audit readiness
• Develop and manage the operational budget across people, technology, and vendors
• Manage jrni's cyber insurance relationship and renewals
• Work with Customer Success to ensure smooth service delivery and operational excellence
• Build, mentor, and retain effective, engaged DevOps, security, and IT teams
• Define clear career paths, performance objectives, and development plans
• Foster a blameless, learning-oriented culture
• Manage on-call rotations and keep workloads sustainable and healthy
• Collaborate across Sales, Customer Success, Product, and Engineering
• Own responses to customer security questionnaires (SIG, CAIQ), RFPs, and audit requests; maintain a customer-facing trust center
• Act as security executive sponsor in enterprise sales cycles
• Partner with Legal and Product on data residency, classification, retention/deletion, and DSAR fulfillment
• Establish KPIs (uptime, MTTD/MTTR, audit closure, remediation SLAs, CSAT) and report to execs and the Board
