Coca-Cola, LinkedIn, Adobe, LVMH and Bayer are just a few of the 2,400+ global companies who rely on our best-in-class platform.\nOur Winning Culture is the engine that drives our teams of innovators. We champion diversity of thought and ideas, we behave like leaders regardless of title, we are committed to achieving ambitious goals, and we love celebrating our wins - big and small.\nSupported by operating principles of being strategy-led, values -based and disciplined in execution, you’ll be inspired, connected, developed and rewarded here. Everything that makes you unique is welcome; join us and let’s build what’s next - together!\nRole Summary:\nAnaplan is building a formal security architecture practice, and this role leads it. You will turn security architecture into a deliberate, reusable asset for the company: reference architectures, identity and authorisation patterns, cryptography standards, and AI guardrail designs that become the natural, low-friction path for engineering rather than a checkpoint to work around. This is a people-leadership role with deep technical scope, reporting to the Director of Product Security. As Anaplan's AI capabilities and enterprise footprint grow, consistent and well-reasoned architecture decisions matter more with every product that builds on them. You will own that surface, set the standards engineering builds against, and lead a senior team to make secure-by-design the default.\nAnaplan is not a simple SaaS application. The platform performs highly dimensional, enterprise-scale modelling with responsive recalculation and strong correctness expectations. The technical surface area includes the legacy Hyperblock engine, the newer Polaris engine, and a growing set of AI-powered products, including CoModeler for AI-assisted model building and CoPlanner for conversational, analyst-style planning support. AI is expanding both the capability and the attack surface of the platform, which raises the value of getting identity, authorisation, supply-chain integrity, and guardrails right by design. Security architecture has high leverage here because it sits close to engineering and platform decisions, and the team is small enough that a strong hire shapes the standards rather than inheriting them.\nYour Impact:\nLead the security architecture practice: define how architecture review works at Anaplan, what gets reviewed, when, by whom, and against which bar.\n\nOwn the reusable patterns: drive security reference architectures, identity and authorisation patterns, cryptography architecture, and AI guardrail design as living standards that engineering adopts by default.\n\nSet security engineering principles: establish and maintain the standards that shape how the platform is built, and keep them legible and usable for engineers.\n\nReview the highest-risk designs: lead architecture and design reviews for major platform and AI changes, early enough to influence them.\n\nPartner with platform engineering: engage directly on the Hyperblock and Polaris surface and the AI product line so architecture reflects how the platform genuinely works.\n\nSupport compliance by design: ensure security architecture meets the demands of the enterprise and regulated environments Anaplan's customers operate in.\n\nCodify decisions into policy-as-code: turn architecture decisions into enforceable, version-controlled guardrails wherever that reduces toil rather than adding it.\n\nBuild and develop the team: hire, coach, calibrate, and mentor the architecture team, and hold a consistent technical bar.\n\nYour Qualifications:\nA track record building or leading security architecture in a SaaS or cloud-first environment, with scope across multiple teams.\n\nDeep architecture credibility: identity and authorisation, cryptography, secure-by-design, and threat modelling at scale.\n\nEnough hands-on depth to challenge weak designs on their merits; this is a security leader who stays technically credible, not purely managerial.\n\nPeople-leadership judgement: hiring, coaching, calibrating a senior team, and making hard calls on performance.\n\nExperience aligning architecture to enterprise and regulated environments.\n\nA clear, non-hyped view of how AI changes the architecture surface: identity, authorisation, supply-chain integrity, and the need for guardrails.\n\nNice to have\nWorking familiarity with AI security standards and references such as the NIST AI RMF, ISO 42001, MITRE ATLAS, or the OWASP LLM Top 10.\n\nHands-on experience with policy-as-code and turning standards into enforced controls.\n\nContributions to security standards, frameworks, or industry practice.\n\nOur Commitment to Diversity, Equity, Inclusion and Belonging (DEIB)\nWe believe attracting and retaining the best talent and fostering an inclusive culture strengthens our business. DEIB improves our workforce, enhances trust with our partners and customers, and drives business success. Build your career in a place where diversity, equity, inclusion and belonging aren’t just words on paper - this is what drives our innovation, it’s how we connect, and it contributes to what makes us a market leader.
