• Partner directly with portfolio managers, traders, and quantitative researchers to translate business requirements into robust technical solutions.
• Build and enhance trading infrastructure, portfolio analytics platforms, and real-time market data processing systems.
• Develop data pipelines to ingest, normalize, and process large volumes of market, reference, and alternative data.
• Build tools supporting P&L calculations, risk analytics, position management, and portfolio exposure monitoring.
• Develop RESTful APIs, microservices, and distributed applications that integrate with trading and investment platforms.
• Optimize application performance, improve processing efficiency, and troubleshoot production issues.
• Work with relational and NoSQL databases to support high-volume financial data processing.
• Collaborate with infrastructure, DevOps, and data engineering teams to improve system reliability, automation, and deployment processes.
• Participate in architecture discussions, code reviews, testing, and continuous improvement initiatives.
• Take ownership of applications throughout the full software development lifecycle.

Required Qualifications

• 5+ years of professional software engineering experience with strong hands-on Python development.
• Strong understanding of object-oriented programming, data structures, algorithms, and software design principles.
• Experience developing production-grade backend applications, APIs, and data processing systems.
• Strong SQL skills and experience with relational databases such as PostgreSQL, SQL Server, or Oracle.
• Experience with Python libraries and frameworks such as Pandas, NumPy, FastAPI, Flask, or Django.
• Familiarity with multithreading, multiprocessing, asynchronous programming, and performance optimization.
• Experience with Linux environments, Git, automated testing, and CI/CD pipelines.
• Strong problem-solving skills and the ability to work directly with business stakeholders.
• Bachelor's degree in Computer Science, Engineering, Mathematics, or a related technical discipline.

Preferred Qualifications

• Previous experience at a hedge fund, asset manager, investment bank, proprietary trading firm, or financial technology company.
• Understanding of equities, fixed income, derivatives, or other financial instruments.
• Experience supporting front-office trading systems, portfolio management, risk analytics, or P&L platforms.
• Knowledge of market data providers such as Bloomberg, Refinitiv, or FactSet.
• Experience with Kafka, Redis, Spark, Airflow, or other distributed data technologies.
• Familiarity with AWS, Docker, Kubernetes, and cloud-based infrastructure.
• Exposure to quantitative research workflows, backtesting, or systematic investment strategies.
• Experience working in a high-performance, business-facing engineering environment.
