Junior Quantitative Developer Jobs in California

Company Description
Swish Analytics is a sports analytics and trading company building the next generation of predictive sports analytics and exchange-based trading products. We believe that profitable trading is a challenge rooted in engineering, mathematics, and market expertise—not intuition. We're seeking team-oriented individuals with an authentic passion for quantitative trading who can execute in a fast-paced environment without sacrificing technical excellence.

As we expand our presence on betting exchanges, we're building infrastructure and strategies akin to those found in traditional financial markets. Our challenges are unique, and we hope you're comfortable in uncharted territory.

Role Overview
As a Senior Quantitative Researcher, you will own end-to-end research and production pipelines for one or more trading strategies. You'll lead research initiatives that generate alpha and improve execution quality, mentor junior researchers, and collaborate closely with our Trading desk to translate quantitative insights into profitable systematic strategies while maintaining rigorous risk management.

Core Responsibilities

• Own end-to-end research and production pipelines for a strategy

• Lead alpha research initiatives leveraging advanced statistical and machine learning techniques

• Process and analyze high-frequency tick data, order book snapshots, and market microstructure signals with sub-millisecond latency requirements

• Analyze price formation, market liquidity dynamics, and limit order book imbalances across electronic venues

• Build and run Monte Carlo simulations to estimate P&L distributions, risk exposures, and portfolio dynamics

• Develop, backtest, and optimize quantitative trading strategies with rigorous statistical validation

• Interpret complex model outputs and communicate alpha generation mechanisms to portfolio managers

• Write modular, clean, and efficient Python code; build custom analytics libraries and research frameworks

• Lead design reviews and establish data quality and research reproducibility standards

• Guide 1–2 junior researchers through project delivery and model development

• Proactively engage with traders and infrastructure teams to clarify research objectives and resolve data dependencies

Risk Modeling

• Design and maintain real-time risk monitoring systems across multi-asset portfolios

• Develop stress testing and scenario analysis frameworks for tail-risk events and regime changes

• Collaborate with Trading and Risk Management to define VaR limits, leverage constraints, and implement automated risk controls

Requirements

• Minimum of 5 years of experience in quantitative research, systematic trading, or statistical modeling

• Master's degree in a quantitative discipline (Mathematics, Statistics, Physics, Computer Science, Financial Engineering) strongly preferred; PhD a plus

• Expert-level Python skills; able to build production-grade research and trading systems

• Experience processing high-frequency tick data and real-time market feeds

• Familiarity with AWS or similar cloud infrastructure for large-scale backtesting and research

• Track record of mentoring junior quantitative researchers

• Excellent communication skills; ability to present complex quantitative research to portfolio managers and trading desks
