Empower the Individual Through Crypto

Gemini is a crypto exchange and custodian that allows customers to buy, sell, store, and earn more than 30 cryptocurrencies like bitcoin, bitcoin cash, ether, litecoin, and Zcash. Gemini is a New York trust company that is subject to the capital reserve requirements, cybersecurity requirements, and banking compliance standards set forth by the New York State Department of Financial Services and the New York Banking Law. Gemini was founded in 2014 by twin brothers Cameron and Tyler Winklevoss to empower the individual through crypto.

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 want to help you buy, sell, and store your bitcoin and cryptocurrency. Crypto is not just a technology, it's a movement.

At Gemini, our mission is to empower the individual and that includes giving our employees flexibility of choice — our Office Optional Policy allows employees to choose to work from one of our physical locations or from home.

Select roles that are location-specific will still be eligible for flexible schedules.

The Department: Information Security 

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: Senior Application Security Engineer - Advisory

The Application Security team at Gemini ensures that software engineering teams across the company are enabled to securely design, build, test, and maintain the applications that power our business. We aspire to establish a "paved road" for our engineers so that they can more-easily deliver secure software with minimal friction, supporting their work across the entire Secure Development Lifecycle (SDL). The Application Security team considers how we’re balancing friction with security value, fighting back “security theater” by using our expertise with an empathetic, customer-service approach.

Whether we're creating educational opportunities, tailoring secure-development technologies, advising on a new product design, or leading a detailed code review, the Application Security Advisory team is focused on supporting our engineers as early-and-often as possible so that “security first principles" are integrated and verified at every stage of the development lifecycle. Success for our team is measured through a maturity model, tracking our growth as a program with capabilities that increase engineer velocity and ever-improving security.


  • Support engineers across the SDL as an application security subject matter expert, including design reviews, threat modeling, code review, and penetration testing
  • Collaborate with product and engineering on architecting resilient, security-first services
  • Perform deep-dive security assessments to ensure all Gemini products and services follow secure design principles across our product portfolio (web, mobile, APIs)
  • Create and deliver educational content to our engineers including hands-on training courses
  • Develop automation for high-signal, low-noise security tooling to increase code base coverage
  • Partner with third-party security firms to provide external validation of software development
  • Provide subject matter expertise to business partners on vendor selection as necessary

Minimum Qualifications:

  • 5+ years of experience working in application security roles or performing similar job functions
  • Prior participation in source code reviews, security design reviews, threat modeling, penetration testing, or defining security requirements
  • Enjoys working directly with software engineers, including in new languages and tool chains
  • Awareness of numerous vulnerability classes, with knowledge of modern mitigation techniques
  • Detail-oriented communication skills via email, Slack, pull requests, and/or in-person presentations
  • Able to balance a software implementation's relative risk in context to defined business goals
  • Creating and extending software for development tooling to improve security automation

Preferred Qualifications: 

  • Have worked directly with enterprise Scala, Python, and/or C++ code bases
  • Experience exploiting and securing modern web applications
  • Experience working with low-level cryptographic implementations/primitives
  • Experience with blockchain-based technologies and/or smart contracts
  • Experience collaborating directly with engineering and product teams
