Director of Cloud Infrastructure & Security

ParisTech – Engineering /Permanent contract /HybridVestiaire Collective is the leading global platform for desirable pre-loved fashion and a pioneer in transforming how people consume fashion.Our mission is simple: make circular fashion the norm, not the exception.Through technology, expertise, and a highly engaged global community, we enable millions of people to buy and sell fashion in a more sustainable way.Founded in Paris in 2009, Vestiaire Collective is now a globally scaled marketplace with offices in Paris, London, Berlin, New York, Singapore, and Ho Chi Minh City, and logistics hubs across Europe, Asia, and the US.Today, we are a team of around 600 people from over 50 nationalities, united by a shared ambition: to drive meaningful change in the fashion industry.Our values, Activism, Transparency, Dedication, Greatness, and Collective, shape how we build, collaborate, and grow every day.About the Role:Vestiaire Collective runs a global marketplace on AWS and GCP — Kubernetes, Kafka, Terraform, Vault, Cloudflare, Datadog, a large PHP application under active modernisation, a series of microservices in different tech stacks (Goland, PHP, Node) and a fast-growing surface of AI-powered services. As Director of Cloud Infrastructure and Security, you will own that entire foundation. You will lead two distinct teams — Cloud Infrastructure (DevOps/SRE) and Security — and be accountable, alongside product development teams for the reliability, cost-efficiency and security posture of everything we run in production.What you will do:Leadership across two teamsLead, grow and retain two teams — Cloud Infrastructure and Security — each small, senior and high-leverage. Hire well; we cannot afford mediocre hires at this size.Define a joint roadmap for both teams, aligned to business priorities and risk appetite, and make explicit calls on what we will not do.Establish clear KPIs, SLOs and risk metrics, and report regularly to leadership on reliability, cost and security posture.Set the operating model: what product teams self-serve behind guardrails versus what your teams own centrally. Foster a culture where reliability and security are shared accountabilities, not tickets thrown over a wall, including establishing a Security Champions model across engineering.Cloud infrastructure, reliability and platformOwn our AWS and GCP footprint end to end: EKS, networking, secrets (Vault), data stores (RDS/Aurora, MSK, ElastiCache, MongoDB Atlas, OpenSearch) and the edge (Cloudflare).Establish real reliability engineering practice: SLOs and error budgets, capacity planning, and a business continuity plan.Drive infrastructure-as-code maturity: Automating Terraform change application, advancing our move to GitOps (ArgoCD), and enforcing guardrails at creation time with policy-as-code (Kyverno/OPA) so provisioning is safe, self-serve and reviewable.Consolidate observability into a single source of truth for metrics, logs and traces.Improve developer experience and delivery throughput: CI/CD (Jenkins, GitHub Actions), paved roads, test environments on demand, and delivery metrics that hold up.Own FinOps: infrastructure cost per unit of business value, cost accountability pushed back to each team, and continued run-rate reduction. Cost discipline is a first-class objective.Support the modernisation of our core platform: Tech migrations, runtime and framework upgrades, and continuous database and Kubernetes upgrades.Attack toil systematically: automate the recurring requests, and hand safe self-service back to product teams rather than absorbing the work.Grow the foundations for AI-augmented engineering and operationsSecurityOwn security strategy and posture across cloud, application, identity, detection and response, building and improving the governance: risk register, published roadmap, remediation SLAs, and a recurring reporting cadence for leadership.Strengthen cloud security posture management (CNAPP) and secure-by-default configurations across all environments.Improve Embedding security into the SDLC and CI/CD: establish full static-analysis and dependency-scanning coverage with clear criteria for when critical findings block a release.Mature vulnerability management, penetration testing and our bug bounty program into one prioritised program with SLAs and aging reports that measurably reduce risk.Advance identity and access management toward least privilege and zero trust: automated provisioning from groups, and periodic access reviews.Mature logging, detection and incident response, closing SIEM coverage gapsSet guardrails for safe AI adoption (shadow AI outside approved paths, data and prompt leakage, prompt injection, model abuse) and defend against AI-enabled fraud and phishing.Ensure compliance with GDPR, PCI DSS v4, NIS2, and CIS v8, including a maintained, reusable evidence library rather than evidence gathered on request.Collaboration with legal and finance teams on compliance and forensic investigation topicsManage third-party and supply-chain risk with vendor tiering and a recurring review cadence.Own the security-built services your team already runs (back-office authentication and ACL, banning/fraud tooling, phone verification) and decide what to keep, hand over or retire.Own endpoint security and partner closely with Corporate IT on device and identity coverage.Keep security awareness and training relevant to a threat landscape that now includes AI-enabled social engineering.Who you are:8+ years in engineering, with 5+ years leading infrastructure, platform, or security teams : ideally in a fast-paced scaleup or marketplace environment.Proven experience managing multiple teams or functions, including hiring and developing senior engineers.Deep, hands-on-credible expertise in public cloud (AWS strongly preferred), Kubernetes, and infrastructure-as-code (Terraform).Track record establishing reliability practice at scale — SLOs, incident management, on-call, capacity planning, disaster recovery.Demonstrable cloud cost optimisation / FinOps results at meaningful scale.Strong grounding in cloud and application security fundamentals — IAM, network security, secrets management, CSPM, OWASP Top 10 — and the judgement to know when to hire the depth you don't have.Working knowledge of compliance frameworks (GDPR, DORA, PCI DSS, NIS2) and how to turn requirements into practical controls.Experience leading through incidents and security events under pressure.Excellent communication skills: able to make a technical trade-off legible to a CFO and a risk decision legible to an engineer.Comfortable operating with a lean team — ruthless prioritisation, automation over headcount, pragmatism over perfection.Our Tech Stack includes: AWS cloud (primary), GCP, Kubernetes, Vault, Cloudflare, Datadog, ArgoCD, Okta. Applications are built on top of PHP 8, Golang and Node.js, using MariaDB, MongoDB and Kafka.What We OfferPurpose-driven work at scaleJoin a company reshaping the fashion industry towards circularity, you directly contributes to reducing waste and extending the life of luxury items.High-impact scope & ownershipWork on products used globally, where your decisions have immediate, measurable impact on millions of users across 70+ countries.A truly international environmentCollaborate with a diverse team of 50+ nationalities across Paris, London, Berlin, New York, Singapore, and Ho Chi Minh City.Career acceleration in a fast-moving scale-upTake ownership early, grow fast, and shape your path, as an expert or a future leader.Learning & growth as a priorityDedicated budget, continuous feedback culture, and opportunities to work on cutting-edge topics (AI, marketplace dynamics, scalability, etc.).Flexible ways of workingHybrid model (typically 2 days remote per week), with trust and autonomy at the core of how we operate.Give back through action2 paid days per year to support a cause of your choice and actively contribute to positive impact beyond your day-to-day role.Competitive compensation & benefitsIncluding bonus, health coverage, lunch vouchers, Gym-Pass, and additional legal perks depending on your location.Research shows that candidates from underrepresented backgrounds including women, people with disabilities, and other marginalized communities, are less likely to apply unless they meet 100% of the criteria.At Vestiaire Collective, we believe diversity drives better decisions, stronger products, and more meaningful impact.If this role excites you but your experience doesn’t align perfectly, we still encourage you to apply, your perspective could be exactly what we’re looking for.Vestiaire Collective is proud to be an equal opportunity employer.PS: We take candidate experience seriously, and your safety too !Vestiaire Collective will only contact you through official email addresses ending in @vestiairecollective.com or [email protected].We will never:Contact you via WhatsApp, Telegram, or similar platformsAsk for payment or banking information at any stage of the processIf you receive a suspicious message, please report it to: [email protected]We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information.
