* **Foundational understanding of derivatives pricing, risk, and exposure calculation concepts.**

* **Strong interest and foundational knowledge in Equity derivatives pricing, including concepts like stochastic volatility models, variance swaps, and basic exotic structures.**

* **Familiarity with Counterparty Credit Risk (CCR) calculations, including Basel IMM, Potential Future Exposure (PFE), and CVA methodologies is a significant advantage.**

* Exposure to Regulatory-based projects such as Model Risk, Basel III, Stress Testing, FRTB, and CCAR is a plus.

* Solid academic background in mathematical finance, statistics, or a highly quantitative field.

* Good understanding of probability theory and stochastic calculus.

* Familiarity with Numerical Analysis and Monte-Carlo methods.

* Experience developing software, preferably in Windows or Linux environments.

* Proficiency in scripting using UNIX Shell (ksh, bash, etc.), Python, and basic VBA.

* Basic knowledge of Relational Databases (e.g., Mongo) is a plus.

* Exposure to Machine Learning Tools and Frameworks (e.g., scikit-learn, PyTorch) is a plus.

* **Proficiency in programming using C++ and Python.**

* Strong analytical and problem-solving skills.

* A meticulous and detailed approach, with a commitment to accuracy, is essential.

* Ability to follow established procedures and operate within guidelines.
