Your next career starts here.

The Yield Team at Fireblocks is looking for an experienced Backend Developer who views security as a core feature, not an afterthought. In this role, you’ll drive growth in the digital asset space by architecting and integrating Digital Asset Yield protocols.

We handle the world’s most valuable assets, and our work demands a security-first engineering culture. You will collaborate with industry leaders to deliver innovative, native products—ranging from decentralized lending to institutional staking—where the safety of customer funds and the integrity of protocol interactions are the highest priorities. Join us to shape the future of the digital assets space by building resilient, trustless solutions for asset optimization.

What You’ll Do

• Architect for Resilience: Design and implement scalable backend systems hardened against the complex attack vectors inherent in Digital Asset Yield environments.
• Secure Protocol Research: Deep-dive into new blockchain technologies, smart contracts, and liquidity protocols, identifying potential vulnerabilities or risks before integration.
• Integrate AI for Enhanced Security & Optimization: Explore and deploy AI/ML-driven solutions to automate the detection of security anomalies, optimize capital efficiency, or enhance the operational resilience of core yield services.
• Mission-Critical Engineering: Solve hard engineering problems where precision is paramount; you’ll ensure that seamless interactions with Digital Asset Yield products never come at the cost of asset security.
• Lead by Example: Champion secure coding practices within the team, participating in rigorous code reviews and threat modeling for all financial logic.

What You’ll Bring

• 8+ years of experience as a Backend Engineer with a proven track record of shipping production-grade code.
• A Security-First Mindset: You don’t just write functional code; you write "defensive" code. You have a deep understanding of common security pitfalls (e.g., reentrancy, oracle manipulation, or logic flaws).
• Experience with Al technologies, such as Claude Code, Cursor and experience building Al tools like Claude Skills, headless agents, context improvements (RAG), bots, MCPs, etc.
• Technical Proficiency: Extensive experience with Node.js in an Agile, CI/CD, and Kubernetes environment.
• Research Prowess: A self-starter who loves dissecting new technologies and understands the security implications of various Digital Asset Yield architectures.
• The Fireblocks Edge:
• Blockchain/Digital Assets Space Experience: A major advantage, specifically if you’ve worked with Digital Asset Yield infrastructure.
• C++ Experience: An advantage, particularly for performance-critical or low-level security implementations.
• Full-Stack Awareness: Frontend experience is a plus, especially regarding secure web practices.
