Senior Back-End Engineer

WireScreen is a fast-growing Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world's most detailed corporate ownership records, the real challenge is connecting the dots. That's where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight. Backed by Sequoia Capital and Harpoon Ventures, our team includes a two time Pulitzer Prize-winning journalist and senior engineers from Google, Twitter, and Oracle. We launched our product just three years ago and already have strong traction with top-tier government customers—and we're just getting started. If you're excited to bring transparency to complex global systems, now's the perfect time to join us. Check out this blog from our CEO on how WireScreen traced DeepSeek's origins back to 2023—well before it went mainstream in 2025.
