The first mission is to bring the same level to our internal teams (Sales, CSM): internal data APIs, unified dashboards and one shared set of KPI definitions.\nThe CDO leads the entire Data & AI function and works hand in hand with the CTO. This is not an administrative role, but that of a leader with strong scientific and mathematical authority, able to understand and challenge the work of senior data scientists and engineers, and to support them on the toughest problems. The goal is not to out-code the team but to structure it, set direction and act as a mirror. You will orchestrate the synergy between infrastructure, Artificial Intelligence (including Generative AI) and Business Intelligence.\nStrategic Objectives & Vision\nRestructuring: Structure the Data department to support Sparteo’s growth.\n\n“Architect” Vision: Define the organizational building blocks (Heads/Leads per pillar) to elevate global technical maturity.\n\nAI Roadmap: Define and execute the strategy for integrating LLMs and Agentic AI to automate yield optimization and internal processes, including our internal data agent and conversational analytics for clients (RAG, text-to-API).\n\nSingle source of truth: One set of KPI definitions, formulas and naming across the group.\n\nData governance & compliance: Own data governance across the group, including GDPR compliance in partnership with our DPO, data retention and minimisation.\n\nDocumentation & knowledge management: Help a strong team move from largely oral knowledge to written, durable processes.\n\nBudget ownership: Manage the Data & AI annual budget and decide where to automate and where to hire.\n\nRepresentation: Carry the voice of Data and AI to the board, investors and external partners.\n\nHolistic Management: Lead the Heads/Leads of each pillar to ensure total coherence of the Data/AI value chain.\n\nThe Three Pillars Under Your Direction\n1. Data Engineering & AI Infrastructure (The Real-Time Backbone)\nHigh-Performance Infrastructure: Validate technological choices to absorb massive volumes of ad-requests with minimal latency, on self-operated, lean infrastructure under tight cost discipline.\n\nProduction Pipelines: Ensure the availability of critical data flows for bidding and monetization and real-time AI inference.\n\nStandardization & Stack: Own the data stack (ClickHouse, SQLMesh, Lightdash, Kubernetes on bare-metal infrastructure operated in-house) and CI/CD processes for seamless scalability.\n\nInternal data platform: Own the evolution of our data warehouse, expose internal data APIs with proper access controls, and make sure our internal data agent queries the warehouse rather than raw data.\n\nCross-functional steering: Co-lead with the CTO the weekly review on infrastructure, pipelines, AI and resource consumption.\n\n2. Data Science (The Algorithmic Heart & MLOps)\nAlgo Wars & Yield: Drive innovation in yield management, floor pricing, throttling, bidding optimization (including bandit approaches) and audience scoring via advanced predictive models and reinforcement learning.\n\nScientific Credibility: Possess a “high-level” mathematical background to guide the team (3 people).\n\nML Lifecycle (MLOps): Validate strategies for auto-tuning, versioning and A/B testing of algorithms within a constrained production environment, including experimentation designs where classic A/B testing reaches its limits.\n\nTeam structuring: Structure the team’s roadmap, objectives and follow-up, and bring fresh perspectives to strong, autonomous experts.\n\nAudit: Audit mathematical models and maintain a standard of excellence.\n\n3. Data Analytics & BI (The Business Engine)\nInsights Strategy: Transform raw data and AI-generated insights into growth levers and revenue strategies for Sales and CSM teams.\n\nData product approach: Data contracts, versioning and internal APIs feeding dashboards and agents.\n\nAccess rights: Own the KPI access-rights policy with business owners, each business line remaining owner of its data.\n\nScale through automation: Scale analytics through the internal data agent rather than headcount.\n\nPartnership: Act as a privileged point of contact for executive management and investors.\n\nHigh-Fidelity Reporting: Guarantee the accuracy of dashboards (supervision of one person).\n\nYour profile for this job\nTechnical Expertise & Real-Time DNA\nAdtech / High-Frequency DNA: Experience in very high-volume environments (High-Frequency Trading, Adtech) is crucial for mastering real-time prediction challenges.\n\nLived scaling experience: Has personally scaled and optimized data and ML infrastructure under tight cost discipline, ideally bare metal and Kubernetes, not only in elastic cloud environments.\n\nData architect: Able to own architecture decisions end to end.\n\nAI Mastery: Strong expertise in Machine Learning, from model design to real-time inference, with hands-on experience building continuous learning pipelines that keep models accurate and reliable at scale. A plus: deep understanding of Deep Learning, Transformers and GPU-based training and inference.\n\nAdvanced AI tooling (mandatory): Builds own skills, plugins and artifacts with LLM assistants (Claude at Sparteo; OpenAI or Gemini equivalents accepted).\n\n“Hands-on” Expertise: Proven ability to audit code, validate data architectures on self-operated infrastructure and master columnar databases and big data pipelines.\n\nAcademic Excellence: Master’s or Ph.D. in Mathematics, Statistics or Computer Science.\n\nLeadership & Management\nTechnical Authority: Engineering, AI and mathematics level “much higher” than the average manager in the sector.\n\nProven Experience: Confirmed experience as a CDO or VP Data managing multidisciplinary teams (Eng + Science + Analytics).\n\nLeads from the front: Writes POCs, pair-programs, lives the problems with the team rather than delegating from afar.\n\nCulture: Direct, transparent communication and strong alignment with our culture deck.\n\nChange management: Brings along senior experts who built the current systems.\n\nDouble Vision: Capable of high-level strategy while retaining the ability to “deep-dive” into technical specificities.\n\nYour mindset to share our adventure\nYou want to make an impact and move things forward collectively, building on what works and questioning what can be improved.\n\nYou solve problems pragmatically and analytically.\n\nYou’re looking for a fast-moving environment where your agility will be an asset. The 80-20 (Pareto) principle holds no secrets for you.\n\nYour ability to listen encourages you to challenge and improve yourself on an ongoing basis.\n\nWhat We Offer\nA unique opportunity to structure an entire Data & AI department within a fast-growing scale-up, reporting directly to the CEO, with full ownership of the Data & AI budget and direct influence on global strategy and investment decisions.\nBenefits & Work Environment\nRemote-first, from France: You work remotely from anywhere in France, with occasional trips to our Paris and Lille offices for your onboarding and key strategic meetings.\n\nEnglish work environment: English is our working language across teams and countries.\n\nAI at your fingertips: Claude is made available to every team member.\n\nClose-knit Team: Be part of our dynamic and united team, where collaboration, innovation, and mutual support drive our collective success and create a thriving work environment.\n\nVibrant Social Events: Engage in regular social gatherings and company events that foster community and celebrate our milestones.\n\nRapid Growth: Experience the excitement of working with a company in rapid expansion mode, impacting the advertising technology landscape across Europe and beyond.\n\nTailored Support: We provide robust career development support, including training programs, career check-ins with HR, opportunities for internal mobility, and performance feedback sessions conducted quarterly or semi-annually, depending on your role.\n\nComprehensive health coverage: We provide a robust health insurance plan, ensuring you are covered and cared for.\n\nAt Sparteo, we believe diversity is a strength. We are committed to providing equal opportunities and fostering an inclusive work environment.
