Senior Manager : Tax Technology Implementations

Role overview

Own the technical implementation program connecting multiple billing domains to an indirect-tax calculation service. The role requires deep indirect-tax knowledge alongside strong technical partnership with engineering: you will translate tax obligations into buildable requirements, maintain the consolidated delivery plan, and make the design and launch decisions that determine whether implementations are accurate, scalable, auditable, and operationally safe. The position is intended for someone working East Coast hours.

Responsibilities

- Write tax requirements and acceptance criteria that engineering teams can implement and that can withstand audit scrutiny. - Review technical designs, challenge approaches that will not scale to future tax rules, and make informed design judgments. - Define scope, sequencing, milestones, critical paths, and downstream impacts for each integration. - Influence the roadmaps of multiple dependent engineering and product teams, keeping tax work prioritized through delivery. - Establish testing, monitoring, rollout, go/no-go, and rollback criteria, ensuring each launch includes runbooks, alerting, and a clear operational owner. - Maintain the integrated plan and risk register, escalate issues with recommendations, and run decision and status cadences across Tax, Product, Engineering, and Data.

Requirements

- At least eight years of experience in a corporate tax department, public accounting, or technology consulting. - Experience delivering global or multi-country indirect-tax implementations and familiarity with non-U.S. indirect-tax regimes. - Hands-on experience implementing marketplace-facilitator tax requirements across jurisdictions. - Program or project-management experience across multiple dependent engineering teams, including dependency mapping and milestone ownership. - Ability to work directly with engineers on design decisions while communicating status and risk clearly to senior leadership. - Strong judgment, planning discipline, and enough subject-matter depth to serve as the trusted source of truth for tax implementation outcomes.

Benefits and work setup

The role offers broad visibility across a complex, multi-domain business and ownership of an end-to-end program spanning multiple brands and jurisdictions. The team provides AI-assisted analysis tools and a substantial tax data mart, with opportunities to help grow a developing function and team.
