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.

The Department: Crypto Core

The Role: Staff Site Reliability Engineer

The Signing team at Gemini develops and manages security tools and platforms, assists users to design and assess the security internal systems, helps integrate complex processes, and works directly with cryptographic software, hardware, and trusted execution environments. The end result is a best-in-class custodian solution for our customers that sets a new bar in digital asset storage.

Security of customers’ digital assets and personal information held with Gemini is our first and foremost priority. The Signing team develops and maintains a trusted execution environment for the purpose of storing Gemini customer’s digital assets. To more easily manage these assets, we are building a scalable signing environment in the cloud that includes a build process to ensure system integrity.

In our work, we research applicable cloud software and hardware security approaches to implement tools and approaches to support our signing environment. This work extends from the hardware (e.g., trusted platform modules or TPMs, hardware security modules or HSMs, and trusted execution environments or TEEs) to the application layer (e.g., application layer communication protocols). Given the need to build and integrate many of these security engineering components, the ideal software security engineer will have a high degree of experience in system security and one or more cloud environments. This engineer will also work closely with various teams including our Security Operations, Product Security, Wallet Engineering, and Platform Engineering teams.

We are a dynamic group with both entrepreneurial spirit and security engineering experience. We have incredibly high aspirations, and we are looking for like-minded individuals who want to guide the transition to a new more decentralized world where access to digital assets is normalized and ubiquitous.


  • Design, build, deploy, and maintain software and security solutions supporting the Signing team
  • Develop tools and automation that integrate security into systems and process
  • Improve the capabilities of the existing signing security infrastructure with a mindset towards infrastructure as code
  • Improve availability and reliability while maintaining acceptable security
  • Integrate the use of hardware security mechanisms into the secure build infrastructure. Example hardware security mechanisms include a trusted platform module (TPM), hardware security module (HSM), trusted execution environment (TEE), smartcard, and/or other similar hardware key storage mechanisms. Example applications of these mechanisms include key storage, signing, encryption, code attestation, and secure boot
  • Participate in disaster recovery (DR) scenarios to validate operability of physical and digital material

Minimum Qualifications:

  • 2+ years implementing software with security primitives
  • Hands-on experience in at least one or more cloud platforms (e.g., AWS, GCP, Azure, or others)
  • Hands-on expertise with at least one area of software security
  • Strong understanding of systems/network security, secure protocol design, secure build and supply chain management, encryption, authentication, key management and applied cryptography
  • Experience implementing software automation processes applied in a software security environment
  • Proficiency in a common scripting language including but not limited to Python, Ruby, etc.
  • Able to troubleshoot and debug issues, and demonstrate a methodical approach to root cause analysis
  • Strong written and verbal communication skills; attentive to details

Preferred Qualifications:

  • 5+ years implementing software with security primitives
  • 2+ years implementing software in AWS
  • 1+ years using monitoring, alerting, and automation tooling (e.g., docker, ansible)
  • Experience in a code-first environment, developing automated solutions to solve support and operational issues
  • Experience working with engineering teams, teaching, training, and mentoring on how to implement best-practice technical solutions
  • Experience with secure build software infrastructure that makes use of a trusted platform module (TPM), hardware security module (HSM), trusted execution environment (TEE), smartcard, and/or other similar hardware key storage mechanism
  • Experience in researching and addressing complex business topics around TPMs, HSMs, TEEs, secure build infrastructure, and applied cryptography
  • Experience implementing software in any of the following: operating systems, kernel development, or cryptographic hardware (PKCS#11, FIPS 201-1 PIV, smartcards, TPMs, HSMs, or TEEs)
  • Ability to read and write code written in Python, Java, Scala, C/C++, and Golang
  • Hands-on expertise with hardware security modules or hands-on expertise with discrete or firmware trusted platform modules or hands-on expertise with trusted execution engines and secure enclaves
  • Knowledge of hardware security, verified/secure boot, tamper resistance, side-channel attacks, anti-cloning, and PUFs
  • Demonstrated ability to convert theoretical security concepts into production
  • Experience in network engineering and security
  • Solid understanding of Product Management and Product Ownership, Agile practices and methodologies
