Job summary

Airwallex in the United Kingdom is seeking a senior Implementation/Technical Solutions Consultant to serve as a trusted advisor on high-value integrations, shaping architecture and solution design across ERP, HRIS, and API connections.

You will partner with activation, onboarding and account teams, translate customer requirements into scalable architectures, troubleshoot complex configurations, and help close gaps with Product and Engineering.

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 successfully delivering cross‑functional projects with stakeholders from diverse backgrounds and job functions, including C‑level executives, technical teams, and operations.
• Exceptional written and verbal communication and presentation skills, including the ability to lead steering meetings, write clear status updates, and influence decisions without direct authority.
• Experience delivering ERP, accounting system, or expense platforms (e.g. Netsuite, SAP, Oracle, Xero) implementations and the associated data flows (GL, cost centres, entities, card feeds).

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.
