Job description

About Us

GRT is a digital-asset trading firm specialising in OTC derivatives, structured products, and liquidity solutions. Our core business is pricing and trading vanilla and exotic options on tokens that have no listed options market — serving token projects, funds, miners, and institutional counterparties who need bespoke risk management. All quoting and hedging is algorithmic and automated, and we compete directly with other well known crypto trading firms.

The Role

We are looking for a Quantitative Options Trader (Junior / Mid-Level) to support the pricing, risk management, and ongoing improvement of our OTC options book
You will work closely with senior traders to help price and manage structures such as covered calls, cash-secured puts, and other bespoke payoffs for clients — while contributing to the automated systems that warehouse and hedge risk.
This is not a passive seat. You will actively contribute to models, tooling, and trading logic, gaining direct exposure to live trading and real capital while developing deep expertise in crypto options markets.

What You Will Do

Pricing & Quoting

• Support the development and calibration of quantitative models used to price options on tokens with no listed options market
• Assist in building and maintaining implied volatility surfaces and pricing frameworks
• Contribute to generating competitive two-way pricing for vanilla and structured OTC products
• Help refine assumptions around spreads, skew, and term structure through backtesting, paper trading, scenario, and walk forward analysis

Risk Management & Hedging

• Monitor the options book and key risk metrics (delta, gamma, vega, theta)
• Assist in maintaining and improving automated hedging strategies
• Support stress testing and scenario analysis across different market conditions
• Help manage inventory and exposures across spot and derivatives venues

Technology & Automation

• Write and maintain code (primarily Python) supporting pricing, risk, and execution systems
• Collaborate with engineering to improve execution infrastructure and data pipelines
• Build tools and dashboards for monitoring performance, risk, and PNL attribution

Strategy & Growth

• Contribute ideas for new products, structures, and trading strategies
• Support research into market opportunities, pricing inefficiencies, and client demand
• Help translate quantitative outputs into actionable trading insights

What You Bring

Required

• 1–4 years of experience in trading, quantitative research, or a related field
• Strong understanding of options fundamentals (Greeks, Black-Scholes intuition, volatility concepts)
• Exposure to crypto markets and/or derivatives trading
• Programming experience in Python (required); familiarity with additional languages is a plus
• Strong analytical and quantitative problem-solving skills
• Ability to work in a fast-paced, high-ownership environment

Preferred

• Experience with options pricing or volatility modeling
• Exposure to OTC markets, market-making, or structured products
• Familiarity with crypto market structure (CEXs, perps, liquidity dynamics)
• Background in mathematics, physics, computer science, or engineering
• Interest in building automated trading systems

What We Offer

• Competitive compensation with performance-based upside
• Direct exposure to live trading and real capital from day one
• Opportunity to learn from experienced traders in a high-performance environment
• Flexible remote setup across APAC time zones
• Clear growth path toward senior trading and strategy ownership
