Quantitative Developer

We're hiring a Quantitative Developer to join the team that owns our firm's core pricing and risk library for live derivatives trading. This isn't a peripheral tool — it sits directly in the critical path of our high-frequency market-making systems and serves as the real-time source of truth for valuation across every strategy we run. It's foundational, it's constantly evolving, and the bar for performance and correctness is about as high as it gets in this industry.

You'll be joining a platform that runs at scale across thousands of servers, built collaboratively across desks and regions, with a strong focus on options and volatility modeling alongside fixed income, ETFs, and FX. This role sits at the intersection of quantitative modeling and high-performance engineering — candidates from Quant Developer or Strategist backgrounds tend to be a strong fit.

• Design and implement high-performance numerical algorithms for pricing and risk
• Build and refine models that reflect real market behavior — balancing accuracy, stability, and latency
• Own core components of the pricing library, from individual models to calculation graphs to central infrastructure
• Partner closely with quants and engineers to ensure models are robust, explainable, and production-ready
• Work across the full lifecycle — research, implementation, validation, and performance optimization
• Write clean, maintainable production code in C++ and Java

• 5+ years of experience in a trading or financial environment working on pricing or risk systems
• Strong understanding of derivatives pricing, particularly options and volatility
• A solid foundation in mathematics, physics, computer science, or a related quantitative field
• Deep C++ and/or Java experience, with a track record of building production systems
• Experience working directly with quants, traders, or similarly technical stakeholders
• Proven ability to translate quantitative models into reliable, scalable systems

• Experience with PDE methods or other advanced numerical techniques
• Familiarity with numerical analysis — stability, convergence, error propagation

Base salary range: $175,000–$300,000 USD, plus discretionary bonus and a full benefits package (paid leave, insurance, and more).
