Who we are

At OpenUp, our mission is to make mental well-being accessible to everyone. Following a ‘high tech & high touch’ approach, we support companies, their employees, and their families with proactive and practical mental health services. Through our digital platform, clients can access 1:1 check-ins, online courses, articles, videos, group sessions, mindfulness practices, and a team of committed mental well-being experts. As we believe that mental and physical well-being are deeply connected, we have also added Lifestyle Experts to our offering, focusing on nutrition, exercise, and sleep. We offer a truly holistic approach that helps people take ownership of their health. We’re proud to work with forward-thinking organizations and are committed to raising the bar on accessible care.

OpenUp was ranked in the Top 3 on LinkedIn’s Top Startups list for 2023, 2024 & 2025 and is continuously growing. We are expanding our international teams and we are searching for like-minded talent. We are already serving 2000+ companies (e.g. Rituals, Deloitte, Decathlon, KPMG, and McDonalds), through which 600K+ employees have access to our product.

The role

• ISMS ownership: own ISO/IEC 27001:2022 and NEN 7510:2024 end to end, the policy set, Statement of Applicability, risk register and the annual revision cycle.
• Audit & certification: prepare for and steer internal and external audits, and drive corrective actions to closure.
• Enterprise security assurance: own security due-diligence questionnaires (DDQs), vendor assessments and the security sections of enterprise RFPs, for new deals and renewals.
• Cloud security governance: govern our Azure posture (Defender for Cloud, vulnerability management, logging, private networking) and turn gaps into a prioritised action list for engineering and hold remediation SLAs. You govern and review; Platform Engineering builds.
• AI governance: build and own our AI governance framework, and review AI features (AI coach, AI-assisted session notes) for data protection, consent, human oversight and model risk.
• AI assurance readiness: lead ISO/IEC 42001 and EU AI Act readiness.
• Incident & continuity: oversee incident management, the data-breach protocol, and business-continuity / disaster-recovery testing.
• Risk management: mature our risk process toward ISO 31000 alignment.

What you'll bring (must-have)

• 6+ years in information security, with hands-on ownership of an ISO/IEC 27001 ISMS through external audits, not just participation.
• A track record of owning enterprise security due-diligence / DDQs.
• Enough Azure cloud-security knowledge (Defender for Cloud, Entra ID, Key Vault, networking, managed identities) to govern and challenge architecture. You do not need to be a cloud engineer, but you cannot be a paperwork-only compliance officer either.
• Strong policy-writing, and the ability to translate controls into practical engineering actions.
• Excellent written and asynchronous communication, and real comfort in a distributed, cross-cultural team.
• Pragmatic, outcome-oriented and comfortable with ambiguity.
• ISO/IEC 27001 Lead Auditor or Lead Implementer certification.

A strong plus (differentiators)

• Familiarity with AI/LLM systems and AI governance frameworks (ISO/IEC 42001, EU AI Act, NIST AI RMF, ISO/IEC 23894). 
• NEN 7510 or other healthcare / high-sensitivity data experience.
• CISSP, CISM or CIPP/E; AI-governance training such as AIGP.
