What you’ll be part of:
Circle is committed to visibility and stability in everything we do. As we grow as an organization, we're expanding into some of the world's strongest jurisdictions. Speed and efficiency are motivators for our success and our employees live by our company values: High Integrity, Future Forward, Multistakeholder, Mindful, and Driven by Excellence. We have built a flexible work environment where new ideas are encouraged and everyone is a stakeholder.
What you'll be responsible for:
Circle is seeking a hands-on and technically sharp Senior Security Engineer, Executive & Endpoint Security to contribute to Circle’s security program while serving as the primary on-site technical network and endpoint security resource for our most sensitive users and locations, including remote offices and other key company sites.
This role has two important pillars. First, and as the primary focus, you will support Circle’s senior leaders and remote locations by implementing and maintaining tailored security controls and capabilities for our most sensitive users and environments. This includes hands-on support for security needs that require a trusted local presence and close partnership with Physical Security.
Second, as a member of Security Operations, you will support Circle’s endpoint and network security programs across our operational environments and key company sites. You will work alongside Security Operations engineers to implement, maintain, and troubleshoot endpoint, network, and infrastructure security controls, with an emphasis on capabilities requiring hands-on, on-site support.
You are comfortable operating across both worlds, from supporting senior leaders and sensitive locations to engineering and maintaining technical security controls across Circle’s endpoint and network environments. If you take pride in precise execution, high-trust relationships, and hands-on work with a direct, tangible impact on the security of a global financial company, we would love to hear from you.
What you'll work on:
- Serve as the primary on-site security resource for Circle’s senior leaders and remote locations, deploying, configuring, and validating tailored security controls with professionalism and discretion.
- Configure and support endpoints, mobile devices, and related technology for senior leaders, ensuring security controls and approved configuration standards are implemented, validated, and maintained throughout the device lifecycle.
- As a member of Security Operations, support Circle’s endpoint and network security programs across operational environments and key company sites, including the implementation, validation, troubleshooting, and maintenance of endpoint, network, and infrastructure security controls.
- Perform on-site security assessments at key company locations, identify control gaps, and execute remediation activities in coordination with leadership and stakeholders.
- Partner with Physical Security and other stakeholders at company locations to ensure endpoint, network, and infrastructure security controls complement physical security protections and site requirements.
- Act as a trusted, in-person security contact for senior leaders and other key stakeholders, delivering a high-touch experience in sensitive and high-visibility settings.
- Develop and maintain rigorous documentation, runbooks, deployment procedures, and configuration standards for on-site implementations, assessments, and control validation to support repeatable execution, operational continuity, and audit readiness.
- Collaborate with IT, Physical Security, Compliance, Engineering, and other cross-functional teams to ensure security implementations align with company standards, operational requirements, and regulatory obligations.
- Provide support for after-hours technical issue response and urgent operational escalation.
- Travel as needed to support senior leaders, remote locations, operational environments, and key company sites.
What you'll bring to Circle:
- 4+ years of experience in security engineering or IT security operations, with meaningful hands-on experience across endpoint, mobile, and network security.
- Willingness and ability to travel regularly, domestically and internationally, to Circle office locations, residences, and secure custody environments; this is a core requirement of the role, not an occasional ask.
- Comfort and professionalism operating in executive and VIP environments. You are discreet, personable, and capable of delivering technical work seamlessly in high-visibility, high-sensitivity settings.
- Hands-on proficiency with endpoint, mobile, and network security technologies, including day-to-day security operations as well as the provisioning, configuration, troubleshooting, and validation of devices and controls for individual high-trust users and environments.
- Strong attention to detail and a methodical approach to on-site configuration, documentation, and control validation; you do not cut corners in high-trust environments.
- Familiarity with physical-logical security boundaries and the ability to coordinate effectively with Physical Security teams on shared control surfaces at office and key locations.
- Solid understanding of zero-trust principles and how they apply to endpoint, mobile, network, and user environment security.
- Ability to work independently in the field, exercise sound judgment without constant supervision, and escalate appropriately when something doesn't look right.
- Strong communication skills, able to explain technical security requirements clearly to non-technical executive stakeholders and document work precisely for audit purposes.
- Experience working in financial services, digital asset management, or financial technology is strongly desired.
- Experience supporting security within office, co-location, or other sensitive operational environments, including site security assessments and the integration of technical and physical security controls.
- Proven experience managing multiple vendor relationships, contract administration, and partner coordination.
