What you’ll do
Take ownership of QA planning and execution across Jumper.Exchange’s core features; from UI to API to cross-chain integrations.
Build, maintain, and scale automated testing frameworks with Playwright, Jest, and related tooling.
Work closely with engineering, product, and security to review requirements, test new releases, and improve our processes.

Nice to have
Familiarity with PostgreSQL and Redis for database and caching layer testing.
Understanding of Ethereum‑based testing libraries (Viem, Wagmi).
Experience in QA for high‑traffic or fintech/blockchain applications.
What you’ll get
Annual team offsites (Thailand in 2023 and Vietnam in 2024 were a blast, Marrakech in March 2025 was blast‑ier; let’s see what happens in 2026!)
