Company mission
To enable every business to easily and securely support digital assets and cryptocurrencies.
Role
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
Our take
The derivatives market has always been attractive for larger investors, but some of the hurdles to overcome are capital efficiency, custody and security. Fireblocks allows for the trading of derivatives on any asset, using any form of collateral while receiving cross-margin benefits across counterparties. Essentially, it enables institutional traders to move digital assets without the operational or security headache.
Fireblocks is banking on assets like cryptocurrencies becoming a new part of the mainstream trade of financial institutions. Although cryptocurrencies are known for being notoriously unstable, when traded properly they can be hugely profitable. So, in a safer landscape, there is a lot of incentive for new participants.
Basically, by raising security standards, a new crop of institutional entities is able to set up shop in the crypto world. This means more business for Fireblocks, and a stabler market which then attracts even more interested parties. The company continues to develop its offering, for example through the recent acquisition of TRES which enables it to deliver the first complete operating system for digital assets.
