Role
Who you are
- 7+ years of experience as a Backend or Full Stack Engineer
- Bachelor of Science (B.Sc.) or equivalent degree/experience
- Blockchain and Web3 experience are a must — including deep understanding of transaction lifecycles, consensus mechanisms, smart contract interactions, and on-chain data
- Proven experience working across multiple blockchain ecosystems — EVM-compatible chains (Ethereum, Polygon, Arbitrum, Base, etc.) as well as non-EVM chains such as Solana, TON, Tron, or similar
- Proficiency in Node.js and TypeScript
- Experience designing and operating microservices in production CI/CD environments
- Strong understanding of security principles, cryptography, and best practices in a blockchain context
- Familiarity with DeFi protocols — AMMs, lending markets, bridging infrastructure, or on-chain routing — is a strong advantage
- Experience with Web3 tooling and libraries (ethers.js, viem, web3.js, Solana web3.js, etc.)
- Demonstrated experience taking products from inception to delivery at scale
- Full stack experience (React, frontend development) — a nice to have
- You think in systems and care deeply about correctness, reliability, and scale
- You’re comfortable navigating ambiguity and can drive technical decisions with limited oversight
- You have a natural curiosity for how blockchain protocols work under the hood — and you actually read the specs
- You thrive in fast-moving environments and can balance shipping velocity with long-term code quality
- You communicate clearly and collaborate effectively across engineering, product, and research
What the job involves
- The FinApps Access team at Fireblocks builds the backbone of on-chain access for some of the world’s largest financial institutions and crypto-native organizations. We operate at the intersection of blockchain protocol engineering and enterprise-grade reliability — designing systems that route, protect, and optimize transactions across dozens of chains at scale
- You’ll work on mission-critical infrastructure powering DeFi connectivity, multi-chain integrations, transaction execution pipelines, and on-chain data access — with direct impact on how billions of dollars flow through decentralized networks every day
- Design and build robust, scalable backend services supporting high-volume on-chain transaction flows across multiple blockchain networks — both EVM and non-EVM
- Own end-to-end development of backend components and APIs — from architecture decisions to production deployment
- Lead integrations with DeFi protocols, on-chain data sources, and blockchain nodes across a wide range of chains and ecosystems
- Research and evaluate emerging blockchain technologies, protocols, and standards to keep Fireblocks at the cutting edge
- Optimize existing production systems for performance, reliability, and security — reducing latency and increasing throughput
- Collaborate closely with product, protocol research, and platform engineering teams to deliver high-quality solutions on time
- Drive features from inception through to delivery at scale, taking full ownership of the product lifecycle

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.
