Zinc Tech Stack

Global background-checking platform with automated workflows and direct HMRC integrations

Software Development London, England 51–200 employees Founded 2017 Privately Held

Zinc operates a background-checking platform targeting UK and international hiring teams. The tech stack—Node.js + Express + Vue/React on the front-end, MongoDB + PostgreSQL in persistence, AWS Lambda for orchestration—reflects a pragmatic full-stack SaaS setup. Pain-point clustering around scaling system performance, data pipelines, and engineering capacity, paired with active work on secure-by-design practices and AI governance, suggests the company is transitioning from early-stage tooling toward compliance-grade infrastructure. Engineering-heavy hiring (10 roles) skews senior, indicating either backfill of depleted capacity or a shift toward more structured delivery.
