About the role

Key responsibilities & impact

Lead post-sales technical implementation conversations with merchants, conducting deep technical discovery to understand their systems, integration architecture, and constraints — and translating findings into a clear path forward.
Own the technical onboarding experience, serving as the primary technical point of contact from kickoff to go-live, partnering with internal Engineering and Product teams to identify and address any product gaps and ensure integrations are set up for long-term success.
Establish and maintain technical documentation for merchant onboardings — system architecture diagrams, API inventories, and integration specs — that cross-functional partners rely on throughout the merchant lifecycle.
Build and maintain a library of reusable integration assets — templates, configuration guides, and onboarding playbooks — that improve consistency and reduce time-to-live across the merchant portfolio on the Solutions team.
Lead investigation and resolution of complex post-onboarding technical issues, collaborating with Engineering and Support to drive root cause analysis and communicate findings clearly to internal and external stakeholders.
Own pre-launch QA — including sandbox testing and end-to-end validation of integration flows — ensuring integrations meet a high technical bar before go-live.
Identify and champion AI and automation opportunities that improve operational efficiency, partnering with internal teams to move initiatives from idea to execution.

Requirements

What you’ll need

4-7 years of experience in a customer-facing technical role such as a Solutions Architect, Implementation Specialist, Technical Consultant, or similar client-facing position.
Demonstrated track record of independently leading clients or stakeholders through complex technical implementations or integrations, from scoping through go-live.
Exceptional ability to translate complex technical concepts, architecture, and solutions for both technical and non-technical audiences — including executive stakeholders.
Deep, hands-on experience working with Mid-Market and Enterprise merchants, with the ability to manage competing priorities across multiple accounts simultaneously.
Strong working knowledge of web technologies and integrations, including hands-on experience designing and troubleshooting RESTful API integrations, and a solid understanding of how Javascript, HTML, and CSS interact within a production environment.
Hands-on experience with common integration patterns (APIs, file-based, event-driven, webhooks, etc.) and the ability to recommend the right approach for a given use case.
A proactive, ownership-driven mindset — you identify problems before they escalate, drive solutions end-to-end, and advocate for both the client and the business when tradeoffs arise.
