Security Engineer

Why Etherealize?

Etherealize is building at the intersection of institutional finance and emerging technology. With $40M in funding from Electric Capital and Paradigm, we are bringing together the best minds from Ethereum and Wall Street to rebuild the infrastructure that underpins the financial system—faster, safer, fully on-chain.
‍
Security is not a cost center here. It is a client-facing differentiator and a core part of how we earn trust with the institutional counterparties we serve. The security program you help build will be referenced in client due diligence packages, auditor engagements, and enterprise contract negotiations.
‍
You will report directly to the CISO, operate with technical autonomy, and have the organizational support to execute a security program that is genuinely production-grade.

What Will You Do?

Etherealize is building its security program from the ground up, and doing it right. While we are still at the startup level, we are moving rapidly toward enterprise grade security controls, processes, and procedures. We are hiring a Security Engineer who will serve as the hands-on execution layer of a security strategy designed by the CISO and backed by organizational investment.
‍
This is not a compliance checkbox role. This is a builder role.
‍
You will be executing the technical implementation of a modern, cloud-native security stack, standing up identity enforcement, endpoint protection, cloud posture management, threat detection, and GRC evidence pipelines that are production-grade and auditor-credible. You will work directly with the CISO to accelerate our security timeline, improve controls, and create the automation infrastructure that compounds in value across every future review cycle.
‍
The work you do here becomes the foundation Etherealize scales on for years to come. If you want to build something that matters and have your fingerprints on a security program early in its journey, this is that role.

Strategic Alignment

This role is a direct investment in Etherealize's revenue acceleration and operational scalability. You will succeed in this role by delivering:

• Accelerated Security Improvement: Partnership with the CISO for hands-on, parallel, technical execution, across many aspects of security engineering and GRC.
• Improved Audit Quality: Effective, well-optimized, technical integrations that produce clean, timestamped, auditor-legible evidence chains across every control.
• Automation Compounding: Secure, automated processes for threat prevention, detection, & response that scale with the company's growth.

Technical Requirements

‍Security Infrastructure & Implementation

• Design, deploy, and maintain core security controls across identity, endpoint, cloud, and application layers. including SSO/MFA enforcement, MDM, EDR, CSPM, secrets management, and DLP
• Own the technical integration of security tooling across the organization's environment, ensuring controls are properly configured, enforced, and producing auditor-credible evidence, not just deployed
• Take responsibility for the technical execution of the organization's security roadmap under the direct guidance and support of the CISO, driving parallel workstreams across infrastructure, GRC, and daily operations.

‍

‍Monitoring, Detection & Incident Response

• Build and maintain detection coverage across all cloud and endpoint systems; validate alert paths through formal, documented test scenarios
• Monitor security alerts and logs for anomalous activity; investigate potential incidents and deliver timely, structured updates to the CISO

‍Vulnerability & Patch Management

• Lead the vulnerability management lifecycle: scanning, triage, SLA-tracked remediation, and patching verification across cloud workloads, endpoints, and system dependencies.
• Maintain a complete inventory of non-human identities (service accounts, API keys, bot tokens, Lambda roles) including ownership, rotation schedules, and expiry tracking

‍

‍Automation & Continuous Improvement

• Identify and implement automation across security controls, alerting, evidence collection, and operational workflows to reduce manual burden and improve program scalability
• Proactively identify gaps in the security posture and regularly bring forward recommendations to the CISO

‍GRC & Compliance Support

• Work with the CISO to maintain alignment between technical controls and governance and compliance requirements.
• Collect, maintain, and organize audit evidence & artifacts to support efficient, clean audit engagements
• Collaborate with the CISO on gap analysis against SOC 2, and other evolving requirements.

‍
‍Employee Lifecycle & Operational Support

• Assist with security onboarding for new employees, including device enrollment, identity provisioning, and access grants, and offboarding, including well-documented access revocation and device decommission.
• Develop and maintain documentation of security configurations, standard operating procedures, and remediation efforts
• Provide technical security support to Etherealize staff as needed.

Qualifications

Required

• This role is based in Austin, Texas (hybrid). If you are not in Austin or willing to relocate to Austin, this is not the role for you.
• 3+ years of hands-on security engineering experience in a cloud-native environment
• Demonstrated experience implementing and administering identity and access management platforms
• Hands-on experience with AWS security services (IAM, CloudTrail, GuardDuty, Security Hub, Secrets Manager)
• Working knowledge of cloud security posture management tools (Wiz, Prisma Cloud, Prowler, or equivalent)
• Working knowledge of integrating SAST/SCA tooling into CI/CD pipelines and managing vulnerability remediations
• Ability and willingness to produce audit-quality security documentation and evidence artifacts
• Understanding of where AI fits into the security stack today and where traditional processes are still needed.
• Be eager to adapt to and to implement increasingly AI driven processes.
• Comfortable operating in a high-autonomy, high-accountability environment with direct Executive leadership visibility

‍Preferred

• Experience supporting a SOC 2 audit end-to-end
• Familiarity with GRC platforms (Vanta, Drata, SecureFrame, or equivalent) including control mapping and evidence collection
• Scripting experience for security automation
• Exposure to DLP tooling and/or AI data governance
• Familiarity with NIST CSF, NYDFS Part 500, or equivalent regulatory frameworks
• Experience in a startup or high-growth environment where the security program was built, not inherited
  ‍

Certifications (Preferred, Not Required)

• AWS Solutions Architect - Associate
• AWS Certified Security - Specialty
• Certified Information Systems Security Professional (CISSP)
