Company Description

Our client is an AI-first B2B SaaS company building an API-native platform that helps global enterprises manage complex regulatory and compliance workflows across more than 120 countries.

The platform combines modular infrastructure, APIs, automation, and AI-powered capabilities to help businesses manage compliance obligations, transaction workflows, reporting, and audit requirements.

The company works with large enterprise customers across technology, commerce, and financial services and operates in a highly technical post-sales environment. Solution Architects partner directly with client engineering and technical teams to design, implement, troubleshoot, and launch integrations.

This is an opportunity to join a growing post-sales organization where you will own complex enterprise implementations from initial requirements gathering through production Go-Live and post-launch support.
