Backend Engineer - Integrations

About Us

At Tightly, we’re building a platform that helps e-commerce and D2C brands manage and optimise their most valuable asset—capital. Our AI-driven platform helps businesses optimise inventory replenishment, streamline supplier communications, and unlock flexible revenue-based financing. We’re not just solving a problem; we’re creating a new category of software that helps businesses optimise their capital for sustainable growth.

What We’re Building

Tightly integrates deeply with the systems that power modern commerce—ERPs like NetSuite and SAP, e-commerce platforms like Shopify and WooCommerce, warehouse management systems, and more. These integrations are the connective tissue of our platform, enabling real-time data flow that powers our inventory intelligence, demand forecasting, and replenishment engine.
