About Fireblocks

Fireblocks is the institutional standard for digital asset security and settlement. 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

• 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 Testing: You design and execute thorough manual test plans across complex financial and Web3 flows. This is the heart of the role.
• 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.

Who You Are

• Quality-First: You hold a high bar for manual QA and find genuine satisfaction in exploratory testing, edge-case hunting, and breaking things before users do.
• Comfortable in Both Modes: You can build automation, but you're happy to spend a significant portion of your time on manual testing. You see both as core to the role.
• Technically Capable: 3+ years in QA, including hands-on experience building automation across the full stack (Frontend & Backend), preferably with TypeScript.
• Crypto-Technical: You have a strong grasp of blockchain fundamentals, the end-to-end transaction lifecycle, and the logic behind DeFi protocols like staking and bridging.
• AI-Fluent: You already use AI tools to force-multiply your output and analyze complex errors more efficiently.
• Adaptive: You learn multiple domains quickly and thrive in a fast-paced environment that moves at the speed of crypto.
• Analytical: When you see an error, your first instinct is to look at the logs and find the "why."
