Backed by over $1 billion in capital, we are the premier digital asset infrastructure provider trusted by thousands of industry-defining financial institutions, including banks, payment providers, fintechs, and global corporates such as BNY Mellon, BNP Paribas, ANZ Bank, Western Union, Stripe, and Revolut. Built for institutional scale and security, our enterprise-grade platform and network have powered over $14 trillion in digital asset transfers worldwide.

At Fireblocks, security isn’t an afterthought; it’s the foundation of everything we do.

Making Security Real

As a Senior Information Security Engineer, you’ll be on the front lines of protecting the systems, users, and data at scale. This role is about turning strategy, architecture, and intent into enforced controls, effective detections, and resilient operations. You’ll work hands-on with the tools, signals, and incidents that define our real security posture.

If you believe security should be practical, measurable, and embedded into daily operations—and not just documented—we want you on the team.

What the Role Looks Like in Practice

You will be the technical anchor of our internal security posture:

• Architectural Ownership: Deploy, manage, and tune enterprise-grade security stacks (EDR, DLP, IAM, CASB, MDM) with a focus on deep integration and automation.

• The AI Frontier: Lead the charge on AI Security. You will implement and secure AI-driven workflows, ensuring LLM use is governed and protected against emerging threats such as data leakage and prompt injection.

• Proactive Defense: Build and maintain high-fidelity detections and guardrails that align with real-world attack techniques.

• Cross-Functional Synergy: Partner as a peer with Engineering, IT, and DevOps to ensure security controls are frictionless, automated, and effective.

What You’ll Bring

Technical Must-Haves:

• 4+ Years of Experience: Extensive hands-on experience in InfoSec Engineering or SecOps within high-growth, cloud-native environments.

• AI Security Mastery (Required): You are ahead of the curve. You have practical experience securing AI adoption and leveraging AI-driven platforms to scale defensive capabilities.

• Deep Technical Stack: Expert-level knowledge of endpoint security (macOS/Linux), SaaS ecosystems, and Identity (Okta/OIDC).

• The Developer Mindset: Advanced scripting skills (Python is a must) to automate away manual toil and build custom security integrations.

Professional & Interpersonal Excellence:

• Strategic Communication: The ability to articulate complex technical risks as actionable business intelligence for diverse stakeholders, ensuring alignment between security objectives and business goals.

• Collaborative Influence: A track record of fostering strong partnerships with R&D and DevOps. You are a facilitator of "Secure-by-Design" principles, focused on engineering solutions rather than creating administrative bottlenecks.

• Crisis Management & Decisiveness: The capacity to maintain operational composure during high-stakes incidents, applying rigorous prioritization and risk-based analysis to drive remediation.

• Pragmatic Professionalism: A disciplined approach to balancing theoretical security ideals with the functional requirements of a high-velocity, global financial infrastructure.

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.
