About the team The Merchant Services team partners with our clients to realise their full potential through the adoption of Airwallex products that drive their growth and success. Within Merchant Services, our Spend and card implementation specialists sit at the heart of how customers design, launch, and scale their global spend programmes on Airwallex. We influence revenue growth across our Spend and issuing portfolio and collaborate with sales, strategy, product, and engineering teams to provide the best experience for our most valued customers. Our team works alongside commercial teams throughout the pre‑sales, solution design, and integration stages, then owns the orchestration from contract signature through go‑live and early adoption. We are committed to empowering businesses with the tools they need to run high‑performing, compliant, and scalable spend programmes across APAC. What you’ll do As the Senior Solutions Engineer for our Spend Team, you will own the end‑to‑end delivery of complex Spend and corporate card implementations that bring our global spend management products to life for enterprise and high‑growth customers across EMEA. You will turn agreed business requirements and solution designs into actionable implementation 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, Merchant Services, Solutions Engineering, Product, Operations, Risk and external partners (e.g. networks, processors, manufacturers), ensuring that every phase from pre‑sale through go‑live and early spend activation runs smoothly. This role is based in Amsterdam (3 days in office), with implementation coverage across EMEA. 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 where ERP, HRIS, and API integrations are core to the rollout. - Work with sales teams on technical discovery to understand customer systems, data flows, and workflows, and recommend a best-fit integration blueprint, including when and how to leverage APIs and third-party connectors. - Work hands-on with customers to troubleshoot integration hurdles and guide them through complex configuration decisions, focusing on designing robust, maintainable implementations rather than writing code directly. - Serve as a subject matter expert on the broader integration ecosystem (e.g. 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 that make it easier for the wider team to support integration-heavy use cases at scale. - Channel customer pain points and integration feedback into Product and Engineering, influencing the roadmap and prioritisation of features that materially improve implementation outcomes.

Preferred qualifications: - Hands‑on experience working with or alongside integration engineers, solution architects, or technical program managers on API‑based integrations, including familiarity with common web, SSO, and ERP integration concepts. - Formal training or certification in project management or agile delivery (e.g. PMP, PRINCE2, Scrum Master), and comfort setting up operating rhythms such as stand‑ups, steering committees, and executive readouts. - Experience managing strategic or e
