As a Technical Account Manager, you’ll be the trusted technical advisor for a portfolio of enterprise and high-growth customers across Europe. You’ll sit at the intersection of product, engineering and commercial teams: guiding complex API integrations, troubleshooting issues, and using data to drive adoption, expansion and long-term retention.

You’ll combine deep technical understanding of APIs and payment flows with strong stakeholder management skills – from hands-on engineers through to senior commercial leaders. This role is based in London, with a 3 days in office policy.

• Build deep, hands-on expertise in Airwallex’s payment, treasury, issuing and embedded finance products, advising customers on best-practice integration patterns and optimisation opportunities.
• Diagnose and resolve complex technical and operational challenges across the stack, coordinating with Commercial, Engineering, Product and Compliance teams to drive timely, high-quality outcomes.
• Serve as a strategic technical partner for enterprise clients: understand their roadmap and priorities, align Airwallex solutions to their goals, and proactively manage the post-sale relationship to drive adoption, growth and retention.
• Plan and lead regular business and technical reviews (e.g. QBRs) with the commercial owner, surfacing insights on performance, risks and opportunities – and turning them into clear action plans.
• Own technical escalations for your accounts, providing calm, structured leadership through incidents and ensuring clear, executive-ready communication throughout.
• Partner closely with Account Executives and Account Managers to identify and shape expansion opportunities (upsell and cross-sell), contributing technical insight into account plans and commercial proposals.
• Use product usage data, commercial metrics and client health indicators to monitor account health, prioritise initiatives, and recommend strategies that improve outcomes for both customers and Airwallex.
• Stay current on the European payments and fintech landscape (including regulations such as PSD2 and local market nuances) and translate that knowledge into practical guidance for customers.

Strong technical foundation with solid understanding of APIs, SDKs, webhooks and system integrations, and the ability to quickly grasp complex technical architectures.

Proven, hands-on experience designing, implementing and supporting integrations for payment or similar financial product stacks.

Experience acting as a trusted technical advisor to enterprise customers, including managing post-sale relationships, leading structured reviews.

Evidence of a commercial mindset – comfortable partnering with sales and account management teams to identify and shape upsell and cross-sell opportunities.

Fluency in English, with excellent written and verbal communication skills and the ability to clearly explain technical concepts to both engineers and senior non-technical stakeholders.

Self-starter who thrives in a fast-paced, high-growth environment, able to manage multiple complex accounts and willing to travel within Europe as required.

Deep domain knowledge of the European payments, fintech or financial services landscape, including familiarity with regulations such as PSD2, SEPA and major local payment methods.

Proficiency in at least one additional major European language (e.g. German, French, Spanish or Dutch) to support client engagement across the region.

Experience using data and analytics (e.g. dashboards, logs, basic querying) to monitor product usage, understand client behaviour and inform recommendations or prioritisation.

Background working closely with or within Product, Engineering, Compliance and Operations teams, with a track record of influencing roadmaps based on customer needs and market insights.
