Senior QA Engineer

Who you are

• You take real pride in finding what others miss — exploratory testing and edge-case hunting genuinely excite you, and you’d rather break something today than let a user break it tomorrow. You do both automation and manual testing, and treat both as core parts of the role
• 3+ years in Manual QA with hands-on automation experience across the full stack (TypeScript preferred)
• Solid grasp of blockchain fundamentals, the transaction lifecycle, and DeFi logic like staking and bridging
• AI-native – you already use AI tools daily to move faster and cut through complex errors
• Fast learner – new domains don’t slow you down; you keep pace in an industry that moves at the speed of crypto
• Data-driven debugger – when something breaks, logs are your first move, not your last resort

What the job involves

• The Financial Apps unit builds the critical infrastructure that connects institutions to the digital asset economy. Our products cover everything from staking and yield to on-ramps, exchange integrations, and Web3 connectivity (e.g. WalletConnect)
• In this role, you’ll manually test all flows that need validation, and contribute to building out our automation the rest of the time. We need someone who treats quality as a holistic product challenge, takes pride in rigorous manual testing, and is eager to help grow our automation—using AI to move faster at every stage
• Holistic Quality Ownership: You own the quality of the product end-to-end. You don’t just test against a spec; you analyze the spec, find the logical gaps, and suggest improvements to ensure a better final product
• Hands-On Manual QA: You design and execute thorough manual test plans across complex financial and Web3 flows
• AI-Powered Velocity: You leverage AI agents (e.g., Claude Code) to accelerate your workflow, expand coverage, and ship faster without sacrificing depth
• Deep-Dive Analysis: You are comfortable digging into logs and monitoring tools (Datadog/Sentry) to understand why something broke. You aren’t afraid to get your hands dirty in the backend to find the root cause
• Contribute to Automation: When you’re not running manual flows, you help build and maintain automation across backend APIs and frontend interfaces in a fast-paced environment
• Product Partnership: You don’t see yourself as “just a tester.” You are an engineer with a product mindset who actively works to improve the systems you are checking
