GSR Markets

GSR Markets brings together market making, high-touch OTC trading, and treasury solutions for clients across the crypto ecosystem, alongside our own proprietary trading activity. We provide liquidity across more than 60 exchanges globally, execute bespoke and complex trades with dedicated coverage, and support clients with treasury management, liquidity planning, and risk strategies as their businesses scale.

Performance runs through everything the division does, measured in uptime, execution quality, and the strength of the relationships we build with clients and counterparties. It is where GSR's market expertise, and our own capital, translates most directly into results.

Role Overview:

Join a high-performance team at the intersection of trading and technology. You will work closely with traders and engineers to design, test, and implement strategies across market-making, prop, and OTC, and contribute to the low-latency systems (built in Rust) that put those strategies into production.

Success in this role requires strong quant and market intuition, curiosity, and a proactive mindset. You'll be working on complex, performance-critical problems where quick learning, ownership, and continuous improvement are key to making an impact.

Key Responsibilities:

• Research, build, and refine trading strategies across market-making, prop, and OTC.
• Analyze market microstructure and pricing to identify and evaluate trading opportunities.
• Work closely with traders, researchers, and engineers to implement strategies into live trading systems, contributing to development in Rust where needed.
• Build tools and infrastructure to support research, including analytics and optimisation workflows.
• Monitor live strategy performance and investigate issues in real time, contributing to the stability and reliability of live trading.

Requirements:

Rust experience is beneficial; if not, a demonstrable interest in mastering it is essential.

• Strong quantitative foundations, with the ability to reason rigorously about pricing, risk, and market structure.
• Genuine interest in trading systems, financial markets, or market microstructure, with familiarity in concepts such as limit order books, pricing, or real-time systems.
• Experience writing efficient, performance-conscious code in at least one language (e.g., Python, C++, Rust) — comfort picking up new languages is valued.
• Strong foundations in algorithms and data structures.
• Degree in Mathematics, Physics, Computer Science, or a related field — or equivalent practical experience.

What We Offer:

• A collaborative and transparent company culture founded on Integrity, Innovation, and Performance.
• Benefits such as Healthcare, Dental, Vision, Retirement Planning, 30 days holiday, and free lunches when in the office (benefits vary depending on employment location).
• Regular Town Halls, team lunches, and drinks.
• A Corporate and Social Responsibility program as well as charity fundraising matching and volunteer days.
