Fullstack Developer

About Hotel Trader Hotel Trader is a VC-backed, cloud-native B2B platform transforming how hotels connect with global demand. Founded by serial travel-tech entrepreneurs and backed by Highgate Technology Ventures (HTV), we’re building the next generation of hotel distribution—automated, scalable, and integrated directly with CRS/PMS systems. Scale that speaks for itself: • 1B+ search requests per day • 40ms average response time • 200M+ inbound messages daily • Live integrations with Hilton, Highgate, Wyndham — rapidly expanding across the US and Europe We’re a remote-first, high-growth company with a strong engineering culture. Over the past 18 months, we've tripled our team, achieved 100% year-over-year revenue growth, and continue to scale rapidly—with real revenue traction and a growing global footprint. Our focus remains on automation and low-latency infrastructure to power real-time connectivity at scale.
