What you’ll do

As an Implementation Manager, you will own the end-to-end delivery of complex client integrations that bring our global payments and financial products to life for enterprise partners, shopping carts, and payment gateways. You will turn agreed business requirements and solution designs into actionable plans, orchestrating cross-functional teams and external stakeholders to deliver on time, on scope, and to a high quality bar. You’ll sit at the intersection of Sales, Solutions Engineering, Product, and Operations, ensuring that every phase from pre‑sale through go‑live and early optimisation runs smoothly.

This role is based in San Francisco (3 days in office).

Responsibilities:

Take agreed business requirements and solution proposals and translate them into comprehensive project delivery plans, operating rhythms, and execution strategies for end‑to‑end partner integrations (from scoping through full launch).

Own overall project management for client product integrations, including internal and external communication, risk and dependency management, and day‑to‑day orchestration of workstreams across onboarding, configuration, testing/certification, and pilot/launch.

Lead the delivery of partner projects in close collaboration with integration engineers and other technical stakeholders, ensuring functional flows, architecture, and timelines are clearly understood and adhered to.

Drive a core project team across all phases of the sales and delivery lifecycle: pre‑delivery with commercial/sales managers and solution architects, delivery with solution engineers, and post‑delivery with technical account managers and support/operations teams.

Coordinate cross‑functional approvals and inputs from internal stakeholders (e.g., legal, compliance, privacy, risk, operations, finance, product) to secure timely sign‑off on proposed solution designs and integration approaches.

Partner with internal product and engineering teams to prioritise solution requirements needed for a given integration, balancing roadmap constraints with committed client timelines and escalating trade‑offs where required.

Collaborate with internal PMO or program functions to align partner‑specific delivery milestones with broader product roadmaps and operational readiness plans.

Apply professional services methodologies and disciplined project management practices (governance, RAID logs, KPIs, status reporting) to manage complex, multi‑workstream efforts spanning multiple regions and stakeholder groups.

Track and communicate clear metrics across your portfolio (e.g., time‑to‑go‑live, adherence to plan, quality of launch) and lead structured post‑launch reviews to drive continuous improvement of our integration playbooks.
