A PhD is a plus\nA previous experience (long term internship or 1-2 year) in systematic trading, ideally in options\nA strong grasp of options theory: pricing models, greeks, implied volatility dynamics and volatility surface construction\nSolid statistics and analytical skills, supported by an experience with machine learning techniques\nStrong Python coding experience in a professional environment (git, Linux, package management, CI/CD)\nStrong interest in crypto derivatives markets. Experience in the area is a plus but not essential\n\nConduct Rules\nYou must:\nAct with integrity\nAct with due skill, care and diligence\nBe open and cooperative with the FCA, the PRA and other regulators\nPay due regard to the interests of customers and treat them fairly\nObserve proper standard of market conduct\nAct to deliver good outcomes for retail customers\n\nCompany Values\nBe collaborative - by working together across the organisation, we foster teamwork, can better respond to challenges and successfully deliver for our clients\nAct with integrity - we pride ourselves on our honesty and high ethical standards.
