About Dex

Dex connects exceptional software engineers with curated startup and scale-up opportunities in London and beyond. The platform positions itself on three principles: curation (only vet-checked roles from top-tier companies), transparency (salary and terms disclosed upfront), and longevity (ongoing career support across promotions and opportunities). The product sits at the intersection of recruiting and AI—voice agents and matchmaking workflows feature prominently in active development, while the data infrastructure (Kafka, Spark Streaming, low-latency pipelines) suggests the platform is scaling to handle high-volume candidate and role matching. Hiring spans the UK, Belgium, and the US, indicating geographic expansion beyond the London-focused origin.
