Manual QA Engineer

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 We’re replacing outdated, manual workflows 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.
This is a hands-on, high-impact role within a small, independent product team that values 
quality over velocity, and collaboration over ego.


• 2+ years of experience in manual QA testing for web-based SaaS platforms
• Comfortable testing complex workflows and edge cases, not just UI
• Strong attention to detail with a methodical, user-first approach to testing
• Curious, pragmatic, and comfortable in a fast-moving, changeable environment
• Clear communicator with good written and verbal English
• Interested in fintech and private equity is a bonus—but not a requirement
• Willingness to Learn the Industry
Private equity is complex and full of nuance—and that’s exactly what makes our work 
rewarding. You don’t need a background in finance to succeed here, but you do need 
a genuine interest in learning how the industry works. Our most effective QA engineers 
understand the real-world workflows behind the features they test. You'll be expected to 
engage with internal documentation, ask thoughtful questions, and build a working 
knowledge of private equity deal structures over timeResponsibilities:
• Own manual testing for new and existing features across our React/TypeScript frontend 
and Node.js/Nest.js backend
• Review product specifications and Figma designs to write clear, structured test plans 
and exploratory checklists
• Identify and document reproducible bugs in a structured, developer-friendly way
• Manually test workflows and edge cases that are hard to automate—especially across 
API and frontend interactions
• Collaborate closely with developers to understand architecture and expected behaviour
• Run exploratory testing sessions and regression sweeps before key releases
• Work with the team to continuously improve our QA process and overall product quality

Tech You’ll Work With
While your focus is manual QA, you’ll interact with the following stack:
• React.js (with TypeScript)
• Node.js / NestJS
• PostgreSQL
• REST, GraphQL, tRPC APIs
• WebSocket-based interactions
• Figma (for interface reviews)
• Tools like Jira, Playwright (for automated tests), and GitHub


Nice to Have
• Experience with or interest in test automation tools (e.g. Playwright, Jest)
• Exposure to CI/CD tools and deployment workflows
• Comfort testing API endpoints directly (e.g. via Postman or Insomnia)
• Understanding of data flows and backend systems (e.g. Redis, PostgreSQL)
• Previous work in early-stage, product-focused tech companies

Work arrangement
• This is a remote role, UK business working hours (+-2hrs)
