? Senior Developer – High-Frequency Trading (Remote) | Build the Future of Finance

Are you a seasoned engineer with a passion for performance, precision, and pushing the boundaries of what's technically possible? My client—an elite, founder-led crypto-tech outfit—is seeking a Senior Developer (HFT) to drive the evolution of their proprietary trading platform.

Backed by a single-family office with capital capabilities akin to a hedge fund, this is a rare chance to work in a startup environment with the stability and resources of a well-funded operation. You'll work on complex systems coded in Rust, built in-house from the ground up, operating entirely in the cloud and optimised for ultra-low latency and speed.

? What You’ll Be Doing:

• Designing, developing, and delivering high-performance systems for HFT and market-making
• Collaborating with cross-functional teams to shape products and infrastructure
• Coding in Rust or C++, debugging, and leading on architectural decisions
• Mentoring junior engineers and conducting code reviews
• Ensuring systems meet strict standards for speed, quality, and resilience
• Continuously identifying performance bottlenecks and optimising code
• Staying current with tech trends and shaping internal best practices

? What You Bring:

• 5+ years’ software engineering experience in demanding environments
• Deep knowledge of high-frequency trading systems and crypto markets
• Expert proficiency in Rust or C++
• Solid system design and architecture skills
• Startup experience (3+ years in teams under 50 people is a must)
• Strong decision-making, analytical, and debugging capabilities
• Experience working under pressure and adjusting to fast-moving conditions
• Emotional intelligence and an eye for mentoring and leadership
• Knowledge of trading strategies, risk management, and market structure

? Tech Environment:

• Rust, C++, Python
• Fully cloud-native infrastructure
• Proprietary technology stack
• Performance-focused, low-latency architecture
• Agile, flat-structured engineering team

? Why This Role?

• Direct access to technical founders and HFT industry leaders
• Work on a next-gen trading platform from the ground up
• No corporate politics, just results and innovation
• Competitive compensation with room for growth
• 100% remote, high-trust environment

If you're ready to engineer trading systems that outperform the market, this is your shot.
