About the role

Implementation Manager responsible for end-to-end delivery of complex Spend and corporate card implementations for enterprise and high-growth customers across EMEA, coordinating cross-functional teams and external partners from pre-sales to go-live and early adoption.

Responsibilities

  • Act as a trusted technical advisor to customers and internal teams on high-value implementations and expansions, shaping integration approaches, system configuration, and overall solution design.
  • Partner with activation / onboarding and account management teams to translate customer requirements into scalable architectures, particularly ERP, HRIS, and API integrations.
  • Work with sales teams on technical discovery to understand customer systems, data flows, and workflows, and recommend a best-fit integration blueprint including APIs and third-party connectors.
  • Work hands-on with customers to troubleshoot integration hurdles and guide complex configuration decisions, focusing on robust, maintainable implementations rather than coding.
  • Serve as a subject matter expert on the broader integration ecosystem (HRIS and accounting partners), collaborating with Sales, Product, and partners to close gaps and improve integration coverage.
  • Create and maintain internal documentation, playbooks, and lightweight tooling to support integration-heavy use cases at scale.
  • Channel customer pain points and integration feedback into Product and Engineering to influence roadmap and feature prioritisation.

Qualifications

  • Bachelor’s degree in a related field (e.g. Business, Finance, Engineering, Information Systems) or equivalent practical experience.
  • 5+ years of experience in implementation, onboarding, customer success, or project/program management, managing complex multi-stakeholder technology or financial services implementations.
  • 4+ years of client-facing delivery or professional services experience in a high-paced environment (e.g. SaaS, fintech, consulting, systems integration, enterprise implementation).
  • Proven track record of delivering cross-functional projects with diverse stakeholders including C-level executives, technical teams, and operations.
  • Exceptional written and verbal communication and presentation skills, including leading steering meetings and influencing decisions.
  • Experience delivering ERP, accounting system, or expense platform implementations (e.g. Netsuite, SAP, Oracle, Xero) and related data flows.
