Description

Role Overview We are seeking a Technical Lead to lead the design and delivery of a new product vertical: visitor identity resolution and data enrichment, built on top of tawk.to's customer engagement platform. This person will own the technical vision and execution of a real-time identity graph that leverages billions of interactions across millions of tawk.to-powered websites to identify, resolve, and enrich anonymous website visitors — turning "unknown visitor from Denver" into "Sarah Chen, VP of RevOps at Acme Corp, viewing your pricing page for the third time this week." This is a zero-to-one build. You will architect the identity graph, select and integrate third-party data providers, design the data model, and ship the MVP. You'll work directly with the CTO and collaborate with teams across the platform to wire identity signals from our Chat, Scheduler, and Form Builder products into a unified resolution system. If you've built identity resolution systems, worked in AdTech or MarTech data infrastructure, or designed enrichment pipelines at scale — this is your role. What You'll Build A cross-site identity graph that links browser fingerprints, cookies, IPs, and self-identified contact data (from chat, scheduler bookings, and form submissions) into unified person and company profiles across millions of properties. A real-time resolution engine that identifies visitors within milliseconds of page load using a cascading algorithm: cookie match → fingerprint match → IP-to-c
