Software Engineer II, Customs

Why Customs Matters More Than Ever

International trade is under more pressure than ever before. With tariffs, shifting regulations, and geopolitical uncertainty, customs has gone from a back-office function to a boardroom priority. The recent trade crisis—sparked by Trump-era tariffs—has made customs the single most complex challenge for global businesses. For many, it’s the difference between keeping supply chains moving or grinding them to a halt.

That’s where we come in. The Customs Technology team at Flexport is leading the charge. We are building the systems that help entrepreneurs and global brands navigate complexity, stay compliant, and keep the world’s goods flowing.

The opportunity: 

Customs brokerage is one of the largest, most under-innovated opportunities in logistics. Legacy customs brokers are stuck with outdated systems and manual processes—they simply can’t adapt fast enough.

Flexport is growing fast because we’re different. We are the only big tech company in the space, and the only freight forwarder that got founded after the launch of Netscape. Being a tech company, we can move much faster than our competitors, and give our customers the service they expect in this day and age. We can deploy things like LLM agents at scale, in an industry that is ripe to be disrupted by this technology.
