We enable banks, fintechs, and exchanges—like BNY Mellon, Revolut, and ANZ—to securely navigate the blockchain economy. Our platform and network provide the simplest and most secure way for companies to work with digital assets. The Mission: Quality  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. What You'll Do <ul> <li>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.</li> <li>Hands-On Manual QA: You design and execute thorough manual test plans across complex financial and Web3 flows.</li> <li>AI-Powered Velocity: You leverage AI agents (e.g., Claude Code) to accelerate your workflow, expand coverage, and ship faster without sacrificing depth.</li> <li>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.</li> <li>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.</li> <li>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.</li> </ul> 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. <ul class="[li_&]:mb-0 [li_&]:mt-1 [li_&]:gap-1 [&:not(:last-child)_ul]:pb-1 [&:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">3+ years in Manual QA with hands-on automation experience across the full stack (TypeScript preferred).</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Solid grasp of blockchain fundamentals, the transaction lifecycle, and DeFi logic like staking and bridging.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">AI-native - you already use AI tools daily to move faster and cut through complex errors.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Fast learner - new domains don't slow you down; you keep pace in an industry that moves at the speed of crypto.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Data-driven debugger - when something breaks, logs are your first move, not your last resort.</li> </ul><div class="content-conclusion">Fireblocks' mission is to enable every business to easily and securely access digital assets and cryptocurrencies.
