Posted May 31, 2026

What will your day look like? - Lead & Grow the Team: Manage a team of data scientists end-to-end; hiring, onboarding, personal development, performance conversations, and day-to-day support. Coach team members technically and professionally. Identify skill gaps, plan for future needs, and scale the team as the practice grows. Foster a culture of knowledge sharing, curiosity, and quality. - Build, Not Just Oversee: Personally contribute to high-complexity initiatives; designing and shipping ML models, training and inference pipelines, and experimentation frameworks. Bring deep, hands-on expertise in marketing-relevant techniques: uplift modelling, propensity scoring, attribution, next best action, segmentation, causal inference, and recommender systems. Set the technical bar through code and craft, not just review. - Advise Clients Strategically: Partner with account and strategy teams on scoping, proposals, and commercial conversations: you're a credible voice in the room when clients are deciding where to invest. - Act as a trusted data advisor. Proactively identify gaps and untapped opportunities in clients' data and marketing ecosystems. Translate complex findings into business recommendations. - Anticipate business needs and challenges; build lasting client relationships as the go-to person for data science matters. - Deliver End-to-End with Quality:Lead complex data science initiatives from hypothesis and experimentation through model development, validation, and activation. Collaborate closely with Data Engineers and Architects so solutions are grounded in solid infrastructure. Own quality across all team deliverables, with discipline in statistical methods, reproducibility, and insight generation. - Lead the team into Agentic AI:Champion agentic AI as both a way of working and a delivery capability. Coach data scientists to adopt AI-native engineering practices (agentic coding, AI-assisted development, prompt and context engineering) and lead the design of agentic solutions for clients: from internal accelerators to production-grade agents embedded in marketing workflows. We expect you have shipped or prototyped agentic solutions and have a clear point of view on where they create real value. -  Contextualize data science within clients' CRM, campaign, and personalization strategies. Leverage hands-on experience with platforms like Adobe AEP, Salesforce Data Cloud, or Braze to extend marketing measurement and influence communications from a data perspective. -  Establish guidelines, ways of working, and reusable accelerators. Maintain a backlog of data science use cases. Contribute to roadmapping, maturity frameworks, and the data science product catalogue alongside the Global Data Practice Lead. ## Who are you going to work with? You will lead a small, technically capable team of data scientists who need a manager with both technical credibility and genuine investment in their growth. Beyond your team: Data Engineers, Architects, Strategy Consultants, Account teams, and clients directly. ## What do you bring to the table?

5–8 years of hands-on data science experience combining technical depth with client advisory. - Strong expertise in statistical analysis, experimentation, ML techniques (regression, classification, clustering, hypothesis testing, next best action modelling). - Proficiency in Python and advanced SQL. - Solid grasp of adjacent domains: data modelling, ETL/ELT strategy, no-SQL databases, pipeline design—enough to collaborate credibly with engineers and architects. - Domain knowledge in CRM and marketing technology: campaign metrics, measurement frameworks, and experience with platforms such as Adobe, Salesforce, or Braze. - Cloud platform experience (GCP, AWS, or Azure). Advisory & Business
Consulting craft: Run client conversations end-to-end — scoping problems, shaping proposals, writing SOWs, contributing to RFPs, and defending recommendations under challenge. Comfortable moving between boardroom narrative and technical detail in the same meeting. Prior consulting or agency experience expected. - Commercial & advisory instinct: Track record of identifying data-driven opportunities, building maturity roadmaps, and translating data science into business outcomes. Sound judgement on effort, ROI, and prioritisation by impact. People Management
Demonstrated experience managing a team: mentoring, performance reviews, hiring, and day-to-day support. Formal management experience is essential. - Coaching-oriented leadership style. You grow people through trust, feedback, and investment—not top-down direction. - Comfort scaling a team that's still taking shape: anticipating needs, defining roles, onboarding effectively. - Emotional intelligence, empathy, and conflict resolution skills. Excellent communication skills in English. Nice to Have
Agency or consultancy experience in fast-paced, multi-client environments. - CRM certifications (e.g., Adobe CJA, RTCDP). - Familiarity with data governance and privacy (GDPR, CCPA). - Experience with out-of-the-box vendor intelligent services. - Exposure to agentic AI or AI-driven automation use cases. - Management or leadership certifications. ## A leader in personalized customer experiences
