The team
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.
What you will do
- 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.
