WHO WE ARE LOOKING FOR: The Lead Principal Technical Account Manager will lead several of our most strategic agency and political engagements while managing a small team of TAMs. This is a player-coach role: you'll own the technical relationship on high-visibility accounts while developing the people around you. This individual plays a critical role in translating company initiatives through streamlined technical operations. We are looking to hire someone who understands web technology, measurement frameworks, and emerging AI and agentic technologies, learns fast, and is not afraid of complexity. You are comfortable leading high-visibility projects, coaching a dynamic group of TAMs, and setting the standard for technical excellence across the team. WHAT YOU WILL BE DOING: Client & Portfolio Leadership • Manage the post-sale technical relationship for a portfolio of top-tier agency accounts and political advertisers, participating in strategic meetings that require technical consultation. • Know our capabilities and differentiators to identify opportunities that solve client business needs and support revenue growth. • Serve as a subject matter expert on measurement strategy, advising partners on attribution frameworks, incrementality testing, and cross-channel reporting methodologies. • Navigate the unique demands of political advertising — compressed election-cycle timelines, data sensitivity requirements, and rapidly shifting priorities — and build technical operations that hold up under them. • Consult on clients' technology stacks — including data clean rooms, CDPs, and identity solutions — to identify integration opportunities and drive platform adoption. • Ideate, scope, and program manage engineering work to facilitate custom solutions — including AI and agentic workflow solutions — scaled across the portfolio. People & Team Leadership • Directly mentor and manage a small team of TAMs: set goals, deliver feedback and performance reviews, and build individualized development plans. • Coach team members on technical depth, client management, and career growth, and serve as an escalation point on their accounts. • Lead the development of project tracking and portfolio-specific goals based on the company's vision, and define a framework for reporting progress with leadership. • Manage product prioritization, reflecting business needs over time for TAM leadership. • Collaborate effectively with functional leaders to solve business challenges, identify growth opportunities, and drive efficiency across the organization. SKILLS SUMMARY: • Proven people leader — experience managing or coaching direct reports, with the judgment to balance individual-contributor work against team responsibilities. • Strong acumen for technical consulting and adept at influencing client technical investments that drive positive business outcomes; passion for educating, training, and bringing creativity to problem solving. • Familiarity with agency operating models…
