About Swapped.com

We're a bootstrapped, profitable team of 30 making buying, selling, and moving crypto easier. Our products power Polymarket, Trust Wallet, Brave Browser and others: 3M+ users onboarded across 150+ countries.

The role

Ramp is our core product: an on- and off-ramp that businesses embed to let their customers buy and sell crypto. It supports 40+ payment methods, from cards and Apple Pay to bank transfers, across 25+ fiat currencies and 30+ cryptocurrencies. You'd join the Ramp product team as its QA engineer, working directly with the frontend and backend developers who build it. We're looking for someone to own quality end-to-end: think in edge cases, keep releases honest, and surface problems instead of saying everything's fine.

What you'll do

• Test features and releases across frontend and backend before they hit production
• Validate buy and sell flows: cards (incl. 3DS), Apple Pay, Google Pay, bank transfers, across currencies and countries
• Check compliance steps trigger exactly where they should and nowhere else
• Break things first: find the edge cases and failure modes developers miss, especially where money moves
• Test APIs with Postman and dev tools, not just the UI
• Run test plans against per-branch preview environments and regression after deploys
• Turn around urgent testing for releases and merchant launches; fill quieter weeks with exploratory testing you chose yourself
• Maintain bug reports and test cases in Notion, working AI-first with tools like Claude Code

About you

• 5+ years of hands-on manual QA: you decide what to test, when it's tested enough, and what blocks a release
• You find your own work, surface problems and resource needs early, and don't wait to be told
• You prioritise by impact: revenue-affecting bugs get your attention before cosmetic ones
• Comfortable below the UI: APIs and backend behaviour
• Crypto or payments experience is a strong plus
• Fluent with AI tooling but critical of its output
• Full professional proficiency in English, with reliable availability the team can plan around

What we offer

• 45,000 to 55,000 EUR annual salary + yearly performance bonus (1 to 2 months' salary)
• Yearly company trip, annual upskilling budget
• No red tape, no corporate bs
