About the Role

The Platform Security team sits at the core of the Fireblocks platform. We are responsible for the engine that evaluates, enforces, and governs every action taken within the system. If it involves a governance policy, an approval chain, or access control, it touches our team.

We are looking for a strong, ownership-driven Senior Software Engineer to lead our Policy Engine and Governance domain. You will perform mission-critical engineering at high scale, where correctness is everything. This role requires a true "builder", someone who can architect complex, distributed business logic while also having the technical depth and willingness to dive into low-level C++ code to optimize core platform components.

What You’ll Do

• 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.

What You’ll Bring

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.

Role Overview

We are looking for a proactive Security Assurance Lead to advance our security program into a proactive "validate and verify" model. Your mission is to ensure our defenses aren't just present, but effective. In this hands-on technical role will own and manage testing, validating and reporting on our security posture, through automated testing against our controls, and ensure our security stack is optimized, integrated, and fully utilized.

Key Responsibilities

• Security Assurance Management: Define, orchestrate and drive the security assurance program from vision to full implementation.
• Continuous Control Validation: Design and execute automated testing (e.g., Breach & Attack Simulation) to verify that prevention and detection controls are functioning across cloud, SaaS and IT environments.
• Central Visibility Hub: Build and maintain a real-time Security Posture Dashboard. This hub will provide a single pane of glass for the coverage and health of our security stack.
• Tool Optimization & Efficacy: Review our existing security suite to ensure tools are properly configured, integrated, and delivering ROI. You will identify "blind spots" where tools are installed but not effectively monitoring or blocking.
• Offensive Testing Strategy: Coordinate regular external offensive testing cycles such as Penetration Testing, Phishing, etc. and translate "broken" controls and findings into actionable items.
• Operational Excellence: Define clear ownership, maintenance schedules, and lifecycle processes for all security technologies to prevent "tool rot."

Required Experience & Qualifications

• 8+ years experience of cybersecurity engineering and architecting (Infosec/DevSecOps).
• Proven technical capabilities in automation, scripting, AI, etc.
• Experience in offensive testing methodologies and practices such as penetration testing, red team exercises, etc.
• Strong understanding of breach simulation, continuous control monitoring (CCM) and technical validation concepts and methodologies.
• Strong understanding of:
• Cloud and SaaS security (WAF, CNAPP)
• Identity, access control, and infrastructure security (IDM, IDP, PAM)
• Endpoint and corporate IT security (EDR, DLP, SASE)

Required Skills & Attributes

• Self-directed architect: Able to take full ownership of the security assurance roadmap from initial design and selection to a working, breathing program.
• Authority without ego: Able to lead across departments without formal reporting lines. While you will operate independently, success is measured by your ability to partner with peers to achieve implementation and ongoing adherence.
• Critical thinking: Able to challenge, validate and verify, while maintaining trust and collaboration with peers and stakeholders.
• Strategic planning: Don’t just patch and quick fix, but ensure correct practices and procedures are developed to provide assurance over time.
• Executive communication: Clear, concise, and credible with senior leadership.
• Analytical thinking: Attention to details and ability to connect multiple dots into a concise and accurate picture.

Nice to Have

• Experience in crypto, fintech, or highly regulated financial environments
• Familiarity with the NIST Cybersecurity Framework (CSF) 2.0, Cloud Security Alliance (CSA) controls matrix, offensive security frameworks (MITRE), etc.

What You’ll Do

• Design, build, and operate multi-cloud infrastructure at enterprise scale.

• Build and evolve CI/CD pipelines that enable fast, safe, and reliable deployments.

   

• Own infrastructure as code using Terraform (and CloudFormation/Bicep where relevant).

• Operate and troubleshoot managed Kubernetes environments (EKS, AKS, GKE).

• Push infrastructure performance, reliability, and availability to the limit.

• Implement cloud security best practices (IAM, secrets, encryption, network security).

• Partner closely with backend, security, and data teams to enable high-velocity development.

• Make key architectural decisions and influence the future of Eon’s platform.

• Solid experience with Kubernetes and managed services (EKS / AKS / GKE).

• Strong hands-on experience with at least one major cloud provider (AWS, Azure, or GCP).

• Proven experience with Terraform in production environments.

• Experience building and maintaining CI/CD pipelines at scale.

Nice-to-Haves

• Multi-cloud experience (AWS + Azure + GCP).

• Experience in high-scale, data-heavy systems.

• Strong security mindset (DevSecOps, least privilege, defense in depth).

• Experience supporting fast-growing SaaS platforms.

Why Join Eon?

Eon is one of the fastest-growing startups in cloud infrastructure and cyber security. We’re extremely well-funded, trusted by global enterprises, and tackling problems that actually matter.

At the same time, we’re lean, flat, and execution-focused. You’ll work directly with me, be part of the core team shaping the company, and see your work change how enterprises protect and operate their cloud infrastructure.

We demand a lot — because what we’re building is big.
And we take care of our people — because great companies are built by great teams.

If you’re ready to do the best work of your career and build something truly meaningful, now is the time to apply — even if you don’t tick every single box.
