As Head of Security, you will take ownership of the security strategy and execution for a high-performance technology infrastructure powering the decentralized ecosystem. This is a hands-on leadership opportunity to establish and strengthen security across cloud infrastructure, production systems, and engineering platforms. You will lead incident response, proactively manage risks, and embed security best practices into engineering workflows. Working closely with executive leadership and engineering teams, you will have significant autonomy to make critical security decisions. You will also build and develop the security function as the organization scales. This role is ideal for an experienced security leader who combines deep technical expertise with strategic thinking and a strong sense of ownership.

Define and execute the overall security strategy, roadmap, and priorities across infrastructure, cloud environments, and production systems.
Establish and continuously improve security controls covering identity and access management, secrets and key management, network segmentation, logging, monitoring, and threat detection.
Own the incident response lifecycle, including detection, investigation, mitigation, recovery procedures, runbooks, on-call readiness, and regular tabletop exercises.
Develop and maintain threat models and risk registers, identifying vulnerabilities and prioritizing security initiatives according to business impact.
Partner with engineering teams to integrate security into development processes, architecture decisions, and deployment workflows without slowing down delivery.
Assess and manage third-party, vendor, and software supply-chain security risks.
Lead the compliance roadmap, coordinate security audits, and manage customer security assessments and reviews.
Build, hire, mentor, and develop the security team as the organization grows.
Communicate security risks, incidents, and mitigation strategies clearly to executives, engineers, and external stakeholders.
Provide hands-on technical leadership, independently investigating systems, implementing security improvements, and addressing critical vulnerabilities.
