Full Stack Engineer, Blockchain

Join the Blockchain Backend Infrastructure team and take a position in building and maintaining Fireblocks's blockchain management platform. You'll be responsible for building cutting-edge blockchain infrastructure while implementing high-throughput, real-time scalable software solutions.

As a Blockchain Engineer, you will be instrumental in the research and integration of blockchain technologies into the Fireblocks platform. Your responsibilities will include collaborating closely with foundations and developers to gain a deep understanding of blockchain protocols and on-chain projects, then applying that knowledge to implement new features within the platform.

You will focus equally on external protocol integration patterns and internal wallet infrastructure. This role serves as a technical bridge between raw on-chain capabilities and the wallet features delivered to our customers.

What You'll Do

• Implement modern backend applications and infrastructure in a microservices architecture, using the latest technologies and development practices.
• Deep dive into the latest blockchain technology and become an expert in the fundamentals, protocols, and features of the chains we support.
• Collaborate effectively with developers, engineers, and other roles while demonstrating strong independent problem-solving abilities.
• Contribute to production reliability through on-call participation, incident response, and post-incident follow-ups.

What You'll Bring

• 5+ years of backend development experience in modern languages (Go, Python, JavaScript/TypeScript)
• 3+ years of hands-on blockchain development experience
• Experience working on high-scale distributed systems
• Understanding of microservices architecture and API design
• Knowledge of consensus mechanisms, cryptographic primitives, and distributed systems
• Strong problem-solving skills and attention to detail
• Strong verbal and written communication skills and a collaborative mindset

Preferred

• Experience building blockchain solutions for enterprise or institutional use cases
• Understanding of security best practices for smart contracts and blockchain systems
• Demonstrated ability to apply AI tools in day-to-day development
• Understanding of MPC, multi-signature wallets, or other advanced cryptographic techniques
• Bachelor's degree in Computer Science, Engineering, or a related field
• Experience with Docker, Kubernetes, and Helm
