Full Stack Blockchain Engineer Headline

We are looking for a Full Stack Engineer with a strong blockchain foundation. In this role, you will work across the entire stack from user-facing interfaces to backend services and on-chain integrations to build and evolve the systems that power institutional digital asset operations.

You will serve as a technical bridge between raw blockchain capabilities and the polished wallet experiences delivered to customers. This means diving into protocol-level details one day and refining a transaction workflow UI the next. Your blockchain expertise will directly inform how we design, build, and ship features that handle billions in transaction volume.

• Design and build end-to-end features across frontend, backend, and blockchain layers that power Fireblocks' wallet infrastructure
• Architect and deliver mission-critical components while maintaining 24/7 operations with zero disruption to live transaction volume
• Research and integrate blockchain technologies including Layer 2 solutions, cross-chain bridges, staking protocols, and DeFi integrations into the Fireblocks platform
• Develop intuitive, responsive interfaces that surface complex blockchain operations in a clear and actionable way for institutional users
• Collaborate with blockchain foundations, vendors, builders, and customers to understand protocol design, tooling, and integration requirements
• Balance pragmatism with vision - make smart trade-offs to deliver incremental value while steadily advancing toward next-generation architecture goals
• Collaborate with product, engineering, and security teams to define technical requirements and deliver cohesive solutions
• Mentor and guide other engineers on blockchain technologies, full stack patterns, and best practices

• 5+ years of full stack development experience with modern frontend frameworks (TypeScript) and backend services ( Go, or Python)
• 3+ years of hands-on experience in the blockchain ecosystem — working with protocols, on-chain data, smart contracts, or wallet infrastructure
• Knowledge of consensus mechanisms, cryptographic primitives, and distributed systems
• Strong understanding of microservices architecture, API design, and modern frontend patterns
• Demonstrated ability to apply AI tools for programming with experience in vibe coding
• Strong verbal and written communication skills and a collaborative mindset
• Experience working in cross-functional teams and fast-paced environments
• A curious mind, willing to learn, including new coding languages and tech stacks.

Preferred

• Experience building blockchain solutions for enterprise or institutional use cases
• Understanding of security best practices for smart contracts and blockchain systems
• Experience with MPC, multi-signature wallets, or other advanced cryptographic techniques
• Experience with institutional DeFi, staking protocols, or custody solutions
• Experience modernizing and transforming mission-critical production systems with minimal disruption
• Bachelor's degree in Computer Science, Engineering, or related field; Master's degree preferred
