We’re looking for a Senior Project Manager to join the Engineering PMO and support our Integrations Team. This role is a dual-track position that goes beyond traditional engineering project management. You will own both end-to-end execution for integration development and the entire go-to-market (GTM) coordination and release process for partner integrations. This role requires a senior, highly organized operator who thrives in complex, cross-functional environments.

What you’ll do

• Own end-to-end execution of integrations initiatives from planning through launch, ensuring delivery within committed timelines
• Take pre-defined technical and functional requirements from technical leadership and translate them into executable project plans
• Own end-to-end delivery across multiple concurrent integrations by managing scope, timelines, dependencies, and proactively removing risks and blockers.
• Facilitate agile events, including, but not limited to: stand ups, parking lots, backlog refinements, sprint reviews, sprint plannings and/or retrospectives for your team
• Engage with technical leads and engineers to ensure tickets are properly detailed, prioritized and estimated
• Track, analyze and story tell metrics, at the team-level, to help deliver consistent productivity and velocity value and forecast project estimation
• Own the GTM framework for Partner Integrations, including managing a multi-tier launch system, timelines, milestones, and execution standards across all integration types.
• Serve as the single-threaded owner for cross-functional GTM coordination, aligning Engineering, Partnerships, Revenue, and Support teams to drive clarity on ownership, dependencies, and handoffs.
• Drive end-to-end GTM launch readiness and execution, assigning owners, managing deliverables, proactively mitigating risks, and ensuring integrations are fully operational and technically ready for launch.

What success looks like

• Consistently delivers high-impact roadmap initiatives on time and within scope, proactively managing dependencies, mitigating risks early, and maintaining predictable velocity.
• Builds a high-performing, motivated team operating within a strong agile framework, improving estimation accuracy, capacity planning, and team health metrics while continuously increasing delivery efficiency and quality.
• Operationalizes and scales a best-in-class GTM framework for partner integrations, creating clear tiering, launch standards, ownership models, and repeatable processes that reduce friction, eliminate ambiguity, and increase launch velocity across teams.

What you’ll bring

• 5+ years of experience in technical project management, program management, or engineering-adjacent PM roles, ideally supporting integrations or platform teams
• Demonstrated experience managing complex GTM motions at mid-to-large companies, particularly for technical or partner-driven products
• Strong experience owning and delivering projects end-to-end across both engineering and business stakeholders
• Experience working within MarTech, AdTech, or client-facing SaaS platforms is strongly preferred
• Solid understanding of technical concepts and data flows, including APIs, SQL, ETL pipelines, and system integrations
• Experience implementing and maintaining Scrum, Kanban, or hybrid agile frameworks
• Proven ability to manage multiple complex initiatives simultaneously without losing rigor or attention to deta
