About the Team
The Wallet Flows team is leading a strategic transformation of Fireblocks' core infrastructure. We're methodically redesigning and rewriting major system components to create next-generation architecture that enhances security, scalability, and performance.
Our team blends industry veterans and rising talent, united by excellence and a results-driven mindset. We value seasoned expertise alongside fresh perspectives, fostering an environment where pragmatic solutions and innovation thrive together.
About the Role
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.
What You'll Do
  • 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
What You'll Bring
  • 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
Success Criteria & Impact
  • You deliver features end-to-end - from UI to on-chain integration - with high quality and minimal iteration
  • Your blockchain expertise is consistently leveraged as a foundation for architectural and product decisions
  • You are considered a subject matter expert by internal engineering teams across both application and protocol layers
  • Consistent contribution to the Fireblocks platform by pushing impactful design and code to production

For employees hired to work from our NYC HQ, Fireblocks is required by law to include a reasonable estimate of the compensation range for this role. This range is specific to New York City, and takes into consideration a wide range of factors that are reviewed when making a hiring decision, such as years of experience, skills, and other business needs.
It is not typical for a candidate to be hired at or near the top of the pay range and each compensation decision is dependent on each individual case. A reasonable base salary range estimate for this position is $177,000 to $230,000. The base salary is one component of the total compensation package, which for some roles may include a target bonus, a very competitive equity grant, and very generous benefits. While we believe competitive compensation is a critical aspect of you deciding to join us, we do hope you also spend time considering why our mission and culture are right for you. We are creating something transformational here, and we hope you are as excited about the future as we are.
Fireblocks' mission is to enable every business to easily and securely access digital assets and cryptocurrencies. In order to do that, we strongly believe our workforce should be as diverse as our clients, and this is why we embrace diversity and inclusion in all its forms.
