Client Integration Engineer, Payments

We’re looking for a Client Integration Engineer to be the main technical contact for our clients as they connect to our API, which handles stablecoin on / off-ramps using fiat. This is an important client-facing role that helps make the onboarding process smoother and offers continuous technical help, taking a significant burden off our Product and Software Engineering teams. The ideal person will have strong technical skills, great communication, and be dedicated to helping clients succeed. Fluency in Chinese (Mandarin) is required to support our wide range of clients.

What You Will Do

• Guide and support new clients step-by-step through the technical integration of our API for stablecoin fiat on / off-ramps, from initial setup to full go-live.
• Act as the primary technical point of contact for clients, providing hands-on assistance, answering integration-related questions, and offering continuous technical support even after they are live.
• Routinely debug and diagnose technical issues within both sandbox and live environments, working directly with clients to identify and implement solutions.
• Manage and execute technical configuration tasks such as whitelisting, credential setup, and other necessary system configurations.
• Develop and maintain clear, comprehensive technical documentation and resources to empower clients and expedite their integration journey.
• Actively participate in client-facing communication channels (e.g., Slack, WhatsApp) to provide timely and effective first-line technical support.
• Effectively translate client feedback and identified integration challenges into actionable insights for our internal Software Engineering teams, facilitating continuous improvement of our API and services.
• Collaborate closely with our Sales, Product, and Engineering teams to ensure a seamless and positive client experience from initial engagement through successful integration and beyond.
