Sr Director, Solutions Data and Identity at Dentsu

Job description

Job Description: At dentsu, identity and data sit at the heart of everything we do — transforming first-party, and strategic third-party data, B2C, B2B, B2B2C and others into actionable insights and intelligent identity solutions that fuel smarter decisions, personalized experiences, and measurable impact. It’s not just a step in the process; it’s the engine that powers innovation and growth across every stage of our client journey. The incumbent in this role will own the end-to-end technical and commercial solution, and its business outcomes, for dentsu’s B2B identity, audience, and closed-loop media engagement with a strategic enterprise software partner. The role is the design authority for the solution internally, and the external-facing authority on dentsu’s identity capability across the partner’s product, engineering, marketing, and legal organizations. This is a hybrid product solutions and delivery role. The incumbent defines the reference architecture, converts it into a sequenced delivery plan, and drives execution across agency, product, engineering, and legal teams. The role also leads productization of the underlying capability into a packaged partner application, extending a single engagement into a repeatable commercial offering. Success requires an operator who can hold a complex data architecture end to end, defend it under client and regulatory scrutiny, and deliver against contractual dates in a matrixed organization. Key Responsibilities: Solution architecture Own and maintain the reference architecture for the B2B identity, audience, and closed-loop media solution, covering identity resolution against the dentsu identity graph, clean room mediation, audience construction, activation paths, and measurement return path (analytics & attribution). Gather requirements from all key stakeholders across dentsu, the partner, and legal and privacy teams, ensuring their needs are understood, documented, and reflected in the solution design and implementation plan. Author and maintain solution documentation as the single source of truth, and adjudicate design decisions when platform constraints require alternative integration routes. Own the B2B firmographic and contact-level data model underpinning target account list and contact-level activation. Make solution decisions with both technical and commercial outcomes in mind, owning the business case and helping ensure the investment delivers value for clients, partners, and dentsu. Client-facing technical leadership Serve as the primary technical authority to the partner organization on dentsu’s identity, data, and activation capability, including at executive alignment gates and partner conferences. Build and sustain relationships with senior executives at the partner and within dentsu, and serve as the escalation point for issues that threaten the engagement. Maintain a defensible distinction between current capability, committed roadmap, and forward-looking vision when engaging a client that is also a technology vendor, translating between agency, advertising technology, and enterprise software vocabularies without loss of precision. Delivery planning and mobilization Own the project plan from solution design through contract signature and into initial phase delivery, including schedule and RACI documentation for post-signature mobilization. Sequence dependencies across internal functions and client-side deliverables; maintain the critical path; identify, manage, and escalate program, commercial, and regulatory risk early. Deliver defined phase scope against contractual milestones, including short-cycle activation commitments. Own the overall success of the solution, ensuring commitments are delivered on time, key milestones are met, and the expected business results are achieved. Partner product development and productization Lead definition and development of dentsu identity capability packaged as a partner-platform application, including managed package scoping,
