About The Position

The Senior Solutions Engineer will own the technical pre-sales of complex client engagements that bring Airwallex's global payments and financial products to life for enterprise partners, shopping carts, and payment gateways. This role involves translating agreed business requirements into solution designs and actionable plans, orchestrating cross-functional teams and external stakeholders to deliver on time, on scope, and to a high quality bar. The engineer will provide technical trust, ensuring that every phase from pre-sales through go-live and early optimization runs smoothly. This role is based in SF (3 days in office), with implementation coverage across the US.

Requirements

• Bachelor’s degree in a related field (e.g. Business, Finance, Engineering, Information Systems) or equivalent practical experience.
• 8+ years of experience in technical pre-sales, managing complex, multi‑stakeholder technology or financial services implementations.
• 8+ 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.

Nice To Haves

• Hands‑on experience working on API‑based payments integrations/products.
• Experience managing strategic or enterprise engagements as part of a broader account team, including navigating commercial sensitivities while protecting technical quality and scope.
• Ability to thrive in a fast‑moving, ambiguous environment, balancing structured methodologies with pragmatic decision‑making to keep complex projects moving forward.

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 implementation and account management teams to translate customer requirements into scalable architectures.
• 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.
• 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.
