Associate Quantitative Trader, Voleon Securities

The Voleon Group•New York, NY

3d•$175,000 - $175,000•Onsite

About The Position

Voleon Securities (VSec) is building a global market making and principle trading firm, with the Trading Operations team sitting at the middle of it all. This is an opportunity to join the ground floor of a top tier quantitative market making business, supported by our affiliate, Voleon Capital Management, a $25B+ quantitative hedge fund. We apply knowledge of market microstructure, statistics, and software engineering to supervise and continuously improve our automated trading systems, turning data into insights that make these systems better. Today the firm makes markets electronically in fixed income products, and it is actively expanding into new asset classes globally, with the trading desk at the forefront of these expansion efforts. Your colleagues will include internationally recognized experts in artificial intelligence and machine learning research as well as highly experienced finance and technology professionals. In addition to our enriching and collegial working environment, we offer highly competitive compensation and benefits packages, technology talks by our experts, a beautiful modern office, daily catered lunches, and more. As an Associate Quantitative Trader, you will learn the business from the ground up: how our automated market-making system operates, how each asset class and venue we trade behaves, and how we measure and improve our trading. You will help run the desk day to day — monitoring live trading and risk, ensuring accurate strategy behavior, and decomposing our trading into the factors driving it — while spending the majority of your time on project work: building the data pipelines, analytics, and automation that raise the sophistication and scale at which the desk operates. Under mentorship from senior traders, you will grow with the desk as it expands into new markets, and you will develop deep expertise in market microstructure, electronic execution, and the data and statistics that underpin them. This is a hands-on, quantitative role in a fast paced, start-up environment. A large part of the work is curating and querying complex datasets, performing exploratory and statistical analysis, and communicating your findings clearly to traders, research, and leadership. The role is in office and follows U.S. market hours, with a shared on-call rotation.

Requirements

Demonstrated experience and passion for financial markets, with an ability to work in a high ownership, fast-paced startup environment
Proficiency, experience, and understanding of Python and SQL used for data analysis (beyond purely utilizing gen-AI tools)
Hands-on experience working with complex datasets end to end: curation, querying, aggregation, exploratory data analysis, and visualization
A solid foundation in statistics — the ability to frame and answer questions mathematically, identify patterns, and reason carefully about distributions, sample sizes, and uncertainty
Comfort working in a Unix-like environment (command line, shell, git)
Strong data-visualization and communication skills: the ability to turn an ambiguous question into a clear, well-supported answer
Attention to detail and clarity of thought, with rigor about cause and effect
A bachelor's degree in a quantitative or scientific discipline (e.g., statistics, data science, computer science, engineering, mathematics, economics, or a related field)

Nice To Haves

A master's degree, or one or more years of applied data, engineering, or trading experience (including internships)
Experience trading fixed income, or applied market microstructure knowledge
Experience building data pipelines or production-facing tooling (ETL, workflow orchestration such as Airflow, CI/CD, git)
Fluency with data libraries (pandas or Polars and a plotting library) and analytical data stores (e.g., DuckDB, Parquet)
Exposure to the FIX protocol or electronic trading systems

Responsibilities

Monitor automated execution and portfolio risk during U.S. market hours, and respond to alerts, exceptions, and incidents
Track real-time developments across the credit, rates, and ETF markets we trade
Design and build the data pipelines, dashboards, and analytics that measure execution quality, monitor data health, and surface abnormal production behavior
Apply statistical analysis to production and research data to produce actionable insights into our trading, and automate the analyses worth monitoring over time
Contribute to the codebase underlying automated trading operations, and build processes and technology that prevent errors and outages while increasing the desk's capacity
Interface with clients, electronic trading venues, and clearing and financing counterparties
Provide market and data expertise to research and strategy partners
Help extend the desk into new asset classes and markets, such as equities and futures
Obtain and maintain the FINRA licenses required for the role (e.g., Series 7/57)
