Senior Implementations Manager

About the Job

At Xendit, we are looking for a Senior Implementations Manager to lead the successful onboarding of large mainland Chinese enterprise clients onto our payments platform.

In this role, you will own the end-to-end implementation journey — from post-sale handover through to go-live — ensuring clients are set up for long-term success. You will work closely with customers to understand their business models, payment flows, and operational requirements, translating these into structured implementation plans and technical integrations.

You will manage complex onboarding projects involving API integrations, payment method configuration, and system alignment with clients’ internal processes. This includes coordinating across internal teams (Sales, Product, Engineering, Compliance) and external client stakeholders to drive timely and high-quality delivery.

As the primary point of contact during onboarding, you will proactively manage timelines, risks, and dependencies, while maintaining clear and consistent communication with clients — including enterprise stakeholders in Greater China. You will also guide clients through best practices, provide enablement and training, and ensure a smooth transition to post go-live ownership.

This role is ideal for someone who combines strong project management discipline with client-facing experience in complex B2B or fintech environments, and is comfortable operating in fast-paced, high-growth settings.

Minimum Qualifications

• 3–6 years of experience in onboarding, implementation, professional services, or project management roles within B2B SaaS, fintech, or payments environments
• Proven track record of leading end-to-end enterprise implementations, from post-sale handover through to go-live
• Strong project management capabilities, including experience managing timelines, dependencies, risks, and multiple stakeholders across concurrent projects
• Hands-on experience working with APIs, system integrations, or technical product implementations (ability to work closely with engineering teams and translate technical concepts to clients)
• Demonstrated ability to engage and manage enterprise clients, including handling complex requirements, escalations, and senior stakeholders
• Experience working cross-functionally with Sales, Product, Engineering, and Compliance teams to deliver client outcomes
• Strong communication skills in English and Mandarin (business proficiency required) to effectively support Greater China clients
• High level of ownership and accountability, with the ability to operate independently in fast-paced, high-growth environments

Preferred Qualifications

• Experience in payments, fintech, or financial infrastructure, particularly working with APIs, payment flows, or regulated environments
• Prior experience supporting or onboarding enterprise clients in Greater China (Mainland China, Taiwan, Hong Kong)
• Background in consulting, system integration, or professional services, with exposure to structured project delivery methodologies
• Familiarity with project management frameworks (e.g. Agile, Scrum, or Waterfall) and tools (e.g. Jira, Asana, Notion)
• Demonstrated ability to manage multi-market or cross-border implementations, including navigating regulatory, operational, or cultural nuances
• Experience working in high-growth or fast-scaling technology companies, with the ability to adapt processes and operate in evolving environments
• Exposure to data migration, system mapping, or workflow design as part of client onboarding
• Strong problem-solving mindset with the ability to identify process gaps and proactively improve implementation playbooks

Responsibilities

• Own end-to-end onboarding and implementation for enterprise and mid-market clients, from post-sale handover through to successful go-live
• Develop and manage structured implementation plans, including timelines, milestones, dependencies, and clear success criteria
• Act as the primary point of contact during onboarding, building strong relationships with client stakeholders and driving alignment across technical and business teams
• Lead technical integrations, working closely with clients and internal engineering teams on API implementation, system configuration, and workflow alignment
• Proactively manage risks, issues, and escalations, ensuring blockers are identified early and resolved efficiently
• Coordinate cross-functionally with Sales, Product, Engineering, Risk, and Compliance teams to deliver high-quality onboarding outcomes
• Facilitate client workshops, solution discussions, and training sessions to ensure successful product adoption and operational readiness
• Drive clear and consistent communication, including regular status updates, stakeholder reporting, and executive-level summaries where required
• Support onboarding of Greater China enterprise clients, navigating language, cultural, and operational nuances effectively
• Continuously identify opportunities to improve onboarding processes, tooling, and playbooks, contributing to scaling the OIM function
• Ensure smooth handover to post-go-live teams (e.g. Customer Success / Account Management), with clear documentation and context transfer
