About this role

Join Fireblocks as a Senior Software Engineer in Platform Security, leading the Policy Engine and Governance domain. Work on high-scale systems with a focus on security and innovation.

Description

Fireblocks’ platform and network provide the simplest and most secure way for companies to work with digital assets and it is trusted by some of the largest financial institutions, banks, globally-recognized brands, and Web3 companies in the world, including BNY Mellon, BNP Paribas, ANZ Bank, Revolut, and thousands more.

Responsibilities
  • Own the Domain: Take end-to-end technical ownership of the Policy Engine and Governance domain, driving the architecture, design, and implementation from 0 to 1 and beyond.
  • Bridge High-Level & Low-Level: Navigate seamlessly between designing highly available, modern microservices and writing/maintaining performance-critical, low-level C++ code when the system demands it.
  • Build for Scale: Implement robust backend applications to process complex rule evaluations at scale and with minimal latency.
  • Collaborate & Lead: Act as a technical leader within the team, collaborating closely with Product, and other engineering teams to translate complex enterprise governance requirements into scalable technical solutions.
  • Maintain Excellence: Ensure the robustness and maintainability of our services, taking part in incident response, on-call rotations, and operational excellence.
  • Leverage AI: Utilize modern AI tools and agents to accelerate development workflows, while applying critical judgment to validate AI-generated output in complex or high-stakes contexts.
Requirements

Must-Have:

  • 8+ years of backend engineering experience building large-scale, high-volume distributed systems or SaaS platforms.
  • Polyglot & Systems Depth: Strong proficiency in modern backend languages (e.g., Go, TypeScript, Python, or Java) combined with hands-on experience and a willingness to touch low-level C++ code.
  • Architectural Mastery: Deep understanding of system design, microservices architecture, concurrency, and distributed SQL databases.
  • Builder's Mentality: A proven track record of taking deep ownership of a complex product domain, acting as a technical anchor, and pushing projects forward independently.
  • AI Tooling Experience: Hands-on experience working with AI development tools (Claude Code, Cursor, etc.) and the critical engineering judgment to know when to trust and when to override them.
  • Infrastructure Knowledge: Experience working with cloud and backend technologies (e.g., Docker, Kubernetes, AWS, DataDog).

Strong Advantage:

  • Security Mindset: A background in cyber-security, adversarial thinking, or experience working in highly security-sensitive environments.
  • Governance Expertise: Experience building Policy Engines, Rule Engines, Identity and Access Management (IAM) systems, or authorization frameworks.
  • Blockchain Knowledge: Familiarity with the blockchain ecosystem, smart contracts, or digital assets.
