Senior Quant Developer

Project descriptionLead the design and development of advanced quantitative and AI-driven models for market abuse detection across multiple asset classes and trading venues. Drive the solutioning and delivery of large-scale surveillance systems in a global investment banking environment, leveraging Python, PySpark, big data technologies, and MS Copilot for model development, automation, and code quality. Play a pivotal role in communicating complex technical concepts through compelling storytelling, ensuring alignment, and understanding across business, compliance, and technology teams.ResponsibilitiesArchitect and implement scalable AI/ML models (using MS Copilot, Python, PySpark, and other tools) for detecting market abuse patterns (e.g., spoofing, layering, insider trading)across equities, fixed income, FX, and derivatives.Collaborate closely with consultants, MAR monitoring teams, and technology stakeholders to gather requirements, share insights, and co-create innovative solutions.Translate regulatory and business requirements into actionable technical designs, using storytelling to bridge gaps between technical and non-technical audiences.Develop cross-venue monitoring solutions to aggregate, normalize, and analyze trading data from multiple exchanges and platforms using big data frameworks.Design and optimize real-time and batch processing pipelines for large-scale market data ingestion and analysis.Build statistical and machine learning models for anomaly detection, behavioral analytics, and alert generation.Ensure solutions are compliant with global Market Abuse Regulations (MAR, MAD, MiFID II, Dodd-Frank, etc.).Lead code reviews, mentor junior quants/developers, and establish best practices for model validation and software engineering, with a focus on AI-assisted development.Integrate surveillance models with existing compliance platforms and workflow tools.Conduct backtesting, scenario analysis, and performance benchmarking of surveillance models.Document model logic, assumptions, and validation results for regulatory audits and internal governance.SkillsMust haveTechnical Skills:7+ years of experienceInvestment banking domain experienceAdvanced AI/ML modelling (Python, PySpark, MS Copilot, kdb+/q, C++, Java)Must be well versed with SQL and have hands on experience writing SQL (preferably Spark SQL) that is productionized (not ad-hoc queries) for at least 2-4 yearsFamiliarity with Cross-Product and Cross-Venue Surveillance Techniques particularly with vendors such as TradingHub, Steeleye, Nasdaq or NICEStatistical analysis and anomaly detectionLarge-scale data engineering and ETL pipeline development (Spark, Hadoop, or similar)Market microstructure and trading strategy expertiseExperience with enterprise-grade surveillance systems in banking.Integration of cross-product and cross-venue data sourcesRegulatory compliance (MAR, MAD, MiFID II, Dodd-Frank)Code quality, version control, and best practices.Soft Skills:Strong storytelling and communication for technical and non-technical audiencesCollaboration with consultants, MAR monitoring teams, and technology stakeholdersStakeholder management and requirements gatheringLeadership, mentoring, and team guidanceProblem-solving and critical thinkingAdaptability and continuous learningNice to haveUnderstanding of Financial Markets Asset Classes (FX, FI, Equities, Rates, Commodities & Credit), various trade types (OTC, exchange traded, Spot, Forward, Swap, Options) and related systems is a plusSurveillance domain knowledge, regulations (MAR, MIFID, CAT, Dodd Frank) and related Systems knowledge is certainly a plus
