Today, companies of all sizes—from emerging brands to Fortune 500s—use Flexport technology to move more than $19B of merchandise across 112 countries a year. The recent global supply chain crisis has put Flexport center stage as we continue to play a pivotal role in how goods move around the world. We are proud to have the support of the best investors in the game who believe in our mission, solutions and people. Ready to tackle global challenges that impact business, society, and the environment? Come join us. Build the programs to help Flexport grow Since 2020, Flexport's Automation Engineering team (formerly the Low Code team) has used tools like Retool, n8n, Python/Streamlit, and Apps Script to automate the "long tail" of operational complexity across Customs — delivering millions of dollars in ROI. As Flexport moves upmarket, more clients need custom integrations to onboard successfully, and this is the team that builds those solutions quickly and pragmatically.

It's high-impact, high-visibility work on a small team that ships fast and sees its ROI directly. You Will Build, deploy, and maintain production-grade integrations and automations using Retool, n8n, Python/Streamlit, Apps Script, and SQL. Partner with Customs
