About the Company

Gemini is a global crypto and Web3 platform founded by Tyler Winklevoss and Cameron Winklevoss in 2014. Gemini offers a wide range of crypto products and services for individuals and institutions in over 70 countries.

Crypto is about giving you greater choice, independence, and opportunity. We are here to help you on your journey. We build crypto products that are simple, elegant, and secure. Whether you are an individual or an institution, we help you buy, sell, and store your bitcoin and cryptocurrency.

At Gemini, our mission is to unlock the next era of financial, creative, and personal freedom.

The Department: Threat Detection & Response

In the emerging industry of digital assets, there is nothing more important than trust (which is why Gemini’s very first hires were Security experts). The Gemini Security team forms the backbone of all that we do and is as diverse as the number of challenges we tackle in the crypto space. From security architecture and engineering to maintenance of cold storage systems and data centers to cybersecurity and litigation support, our team ensures that our customers, clients, and employees are safe, secure, and supported.

The Role: Principal Security Engineer

Gemini seeks a Principal Security Engineer to drive and lead our Threat Detection and Response (TDR) capabilities. In this role, you will set technical direction, oversee complex projects, lead critical investigations and incidents, and architect scalable solutions that proactively detect and mitigate advanced threats across our infrastructure and services.

This role is required to be in person twice a week at either our Seattle, WA or New York City, NY office.

Responsibilities:

• Define and drive the strategic vision and technical roadmap for threat detection and response capabilities across Gemini’s infrastructure and applications.
• Architect, implement, and maintain scalable, automated security detection systems, response mechanisms, and incident management platforms.
• Lead high-impact security projects involving complex systems integration and cross-functional collaboration, ensuring alignment with strategic business objectives.
• Conduct comprehensive security risk assessments, penetration testing, and vulnerability management, identifying systemic security gaps and driving remediation efforts.
• Direct critical incident response efforts, including in-depth forensic analysis, containment, eradication, and post-incident review to enhance Gemini’s security posture continuously.
• Mentor senior engineers, providing technical expertise, career guidance, and fostering a culture of security excellence and continuous improvement.
• Influence Gemini’s broader security strategy through deep technical expertise, contributing to policy formulation, regulatory compliance, and industry best practices.

Minimum Qualifications:

• 10+ years of experience in security engineering with significant expertise in threat detection, incident response, and cybersecurity automation.
• Proven leadership experience driving complex security initiatives and mentoring technical teams.
• Advanced scripting and coding skills in languages such as Python or Go, coupled with deep expertise in CI/CD, infrastructure as code, and containerization technologies (e.g., Docker, Kubernetes).
• Extensive experience designing and implementing sophisticated detection mechanisms across diverse security platforms (e.g., Splunk, EDR tools).
• Exceptional analytical and problem-solving capabilities, demonstrating rigorous methodologies in root cause analysis and system optimization.
• Strong communication skills, capable of articulating technical concepts clearly to diverse stakeholders, including executive management and external partners.

Preferred Qualifications:

• Expert-level proficiency in memory, network, and host forensics and real-time security analytics.
• Comprehensive experience with advanced threat modeling frameworks.
• Proven ability to develop and deploy large-scale automated threat response and intelligence systems.
• Track record of influencing security strategy at organizational or industry levels.

It Pays to Work Here

The compensation & benefits package for this role includes:

• A discretionary annual bonus
• Long-term incentive in the form of a new hire equity grant
• 401K with company matching
• Flexible time off

Salary Range: The base salary range for this role is between $198,000 - $277,000 in the State of New York, the State of California and the State of Washington. This range is not inclusive of our discretionary bonus or equity package. When determining a candidate’s compensation, we consider a number of factors including skillset, experience, job scope, and current market data.

In the United States, we have a flexible hybrid work policy for employees who live within 30 miles of our office headquartered in New York City and our office in Seattle. Employees within the New York and Seattle metropolitan areas are expected to work from the designated office twice a week, unless there is a job-specific requirement to be in the office every workday. Employees outside of these areas are considered part of our remote-first workforce. We believe our hybrid approach for those near our NYC and Seattle offices increases productivity through more in-person collaboration where possible.

At Gemini, we strive to build diverse teams that reflect the people we want to empower through our products, and we are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, or Veteran status.
