The Department: Onchain
Our team’s mission is to enable Gemini’s internal and external users to seamlessly interact with blockchain networks in a stable, secure, straightforward way. The Onchain group builds Gemini’s onramps to the blockchain “from CSS to ECDSA.” Our teams are solving problems across the entire crypto product user journey, including the user experience of crypto transfers, custody and staking down to the lowest levels of blockchain protocols and cryptographic signing algorithms. Our systems facilitate on-chain transactions for billions of USD worth of digital assets using state-of-the-art technology and security. We have openings across many of our teams, including Asset Transfers, Staking, Cloud Wallets, Protocols, Signing, and Blockchain Infrastructure. The teams are small, capable, agile, and have extensive ownership of the systems and solutions. We are continually growing, solving unique problems, and discovering new opportunities.
The Role: Senior Software Engineer (Frontend)
As a Senior Software Engineer in the Onchain domain, you will work with talented engineers to enhance and expand the features of our blockchain-based products and the supporting platforms, including the Staking, Transfers, and Custody products. You will participate in solutioning for new features and products, helping to drive innovation to bring new value to users. You will contribute to the technical direction and engineering culture within your product team, leveling-up junior engineers in the process. You will also help drive operational excellence in our systems and processes. Our goal is to design, develop, deploy, and support user-facing distributed systems that serve millions of users, with a focus on safety, security, and user experience. We believe in fixing what's broken, automating wherever possible, and constantly improving our processes.

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.
