Manual Tester

Dealstack is on a mission to power private equity. We’re replacing outdated, manual workflows in dealmaking with structured, purpose-built SaaS tools. Founded by industry veterans, our products sit at the intersection of fintech, legaltech, and SaaS—transforming how private equity operates from the inside out. Following strong traction and expansion of our multi-product roadmap, we are hiring a Manual QA Engineer to help ensure our product is stable, intuitive, and production-ready at all times.
