Job description

About the Company

Gemini is a global crypto and Web3 platform founded by Cameron and Tyler Winklevoss in 2014, offering a wide range of simple, reliable, and secure crypto products and services to individuals and institutions in over 70 countries. Our mission is to unlock the next era of financial, creative, and personal freedom by providing trusted access to the decentralized future. We envision a world where crypto reshapes the global financial system, internet, and money to create greater choice, independence, and opportunity for all — bridging traditional finance with the emerging cryptoeconomy in a way that is more open, fair, and secure. As a publicly traded company, Gemini is poised to accelerate this vision with greater scale, reach, and impact.

The Role

As an engineer on the Trading Systems team, you'll architect and solve complex problems that will directly influence the direction of the digital asset space. There's a wide range of problems to solve at Gemini—from properly securing millions of dollars worth of customer funds, to developing innovative new blockchain products, to shaving microseconds off our API response times. We have a strong culture of code reviews, and a focus on security, with the end goal of writing and shipping high-quality code by getting things right the first time.

We are seeking a high-caliber Staff Software Engineer to join our Trading Systems team in Singapore, specifically anchoring our Post-Trade Data stream. In this role, you will be a technical leader responsible for shaping our end-to-end data story. You will solve complex architecture challenges for both near real-time and historical data systems, driving our data landscape strategy forward while ensuring our operational posture remains bulletproof. The ideal candidate is a versatile hybrid—someone with deep, specialized data engineering expertise who is also a well-rounded, hands-on software engineer capable of guiding a tight-knit team.

Responsibilities

• Technical Leadership & Strategy: Provide technical direction and mentorship to the local engineering team; own the technical roadmap for the post-trade data stream, ensuring scalability, maintainability, and high-quality engineering standards.
• Data Architecture: Design, build, and optimize robust systems to process, store, and serve critical near real-time and historical post-trade data.
• Strategic Initiatives: Drive key strategic data projects, including the integration and optimization of modern technologies like StarRocks to elevate our analytical capabilities.
• Feature Development: Develop new products and product features on the Gemini platform, working as part of a tight-knit team of two to eight developers.
• Code Quality & Security: Review other software engineers' code for correctness, style, and information security concerns. Engage in refactoring and upgrade projects to continuously improve the codebase.
• Testing & Operations: Write automated tests and work with our QA team to ensure system correctness. Oversee general functionality of risk systems, implement advanced monitoring tools, and maintain a strong operational posture for the post-trade data pipeline.
• Incident & Issue Management: Identify, coordinate, and manage resolution efforts on processing usage and data bottlenecks, owning technical issues through to resolution.
• Project Delivery: Plan and coordinate project implementation efforts, estimate work schedules, and make well-reasoned technical tradeoffs based on business needs.

Requirements

• At least 8 years of software engineering experience, with a proven track record of acting as a technical lead or senior architect.
• Advanced proficiency in at least one backend language. We use mostly Scala and C++ on our backend and TypeScript on the frontend—it's great if you're comfortable in those or if you're willing to learn.
• Heavy hands-on experience in the big data ecosystem, specifically working with distributed processing frameworks like Apache Flink and Apache Spark.
• The ability to work closely across cross-functional teams, manage complex dependencies, and handle multiple competing priorities in collaboration with peers.
• A customer and product-focused mindset, with the ability to balance speed and quality without compromising on security or operational stability.

Preferred Qualifications

• Deep work experience or knowledge of the finance industry, payments, exchange systems, or electronic trading systems.
• Experience working with or being a power user of Bitcoin, Ethereum, and/or blockchain technology.
• Experience with next-generation OLAP databases (such as StarRocks, ClickHouse, or Apache Pinot) for real-time analytics.

Benefits

• Comprehensive health plans covered at 100% for employees and dependents
• Long-term incentive in the form of a new hire equity grant
• Paid Parental Leave
• Competitive paid time off
