Help us Build the Future of Money

Gemini Trust Company, LLC (Gemini) is a licensed digital asset exchange and custodian. We built the Gemini platform so customers can buy, sell, and store digital assets (e.g., Bitcoin, Ethereum, and Zcash) in a regulated, secure, and compliant manner.

 Digital assets and blockchain technology have the power to transform the world for good. This truth, along with our core values, form the bedrock of our company and culture. At Gemini, no job is too small and no project too big as we endeavor to build the future of money. We are a mission-driven, team-based, inclusive, and determined community of thought leaders who invest in each other and the long game. Join us in our mission!

The Department : Engineering

Gemini is regulated and licensed like a bank, but it’s run like a tech startup, and engineering is the core of the company. There’s a wide range of tough problems to solve at Gemini – from properly securing hundreds of millions of dollars worth of customer funds, to developing innovative new blockchain products, to finding new techniques to combat fraud, to shaving microseconds off our API response times, and everything in between.

All of Gemini’s engineers are able to work across the software platform, not just on their own specialization or sub team. We value a thoughtful, collaborative software development process, coupled with a pragmatic approach to problem solving and delivering software.

Reliability, fault tolerance, recoverability, throughput, and latency are what we look for in our systems.

  • Build systems to monitor the status and health of the trading platform.
  • Identify and advocate for changes vital to the stability and supportability of the system.
  • Mentor and advise teammates to ensure new features are efficient, highly available, and fault tolerant.
  • Provide continuity and stability to the production environment.
  • Provide quick response to production issues to help eliminate down time thereby ensuring high availability and performance of our trading platform.
  • Coordinate, prioritize and plan the changes to our trading software thereby ensuring smooth exchange migrations, quick time to market for new features and software.

Requirements:

  • 4+ years developing exchange or trading systems with C++, Java or Scala
  • Delivers testable code using unit testing frameworks such as Googletest and JUnit
  • 3+ years working with order handling or matching engines
  • 3+ years working with FIX or other market data/order protocols
  • 3+ years in building real-time Linux systems
  • In-depth understanding of networking protocols and some experience programming with low-level sockets APIs

Preferred Qualifications:

  • Linux kernel tuning and optimization
  • Experience with margins/derivatives products
  • Experience with continuous integration tools like Jenkins
  • Experience working with multi-language build tools such as Bazel
  • Low latency/lock-free development and design

An Insider's view of Gemini

What’s the vibe like in the office?

Before I started, I was told that taking a job at Gemini was a great idea because of how excited everyone was to be there. After working here for more than two years, I still believe that to be true. The office is constantly buzzing with incredibly smart people who are working to build Gemini into the long-lasting business we know it can be.

Marjorie

Manager, Cash Management

How do you collaborate with other teams in the company?

A risk team is typically seen as a group that says "no”; at Gemini, establishing relationships and collaborating are key to understanding risks, which better enables us to say "yes" (or "yes, but..."). Communicating clearly and regularly, keeping things simple, and being flexible in a complex space reduces the risk of a message being lost.

Yusuf

Head of Risk

How do you make yourself accessible to the rest of the team?

Team meetings and 1:1s are necessary for communication and productivity, but the daily interactions are what really make you accessible. You need to show genuine interest in everyone professionally and personally. I make a connection with each person so they know they are welcome to stop by my desk or ask for my support outside of “scheduled” time.

Jeanine

Managing Director of Operations

How do you empower your team to be more creative?

When we start a project, I challenge my team to look outside of the finance space, to take inspiration from other creative spaces such as art, industrial design, fashion, automotive, etc., and try to translate that into a solution for our industry and users. It's important to set the tone that solutions to problems can come from anyone or anywhere.
