• Base Salary $290K – $395K Offers Bonus

The listed base salary range for this position is based upon the location(s) of this posting. Individual salaries are determined through a variety of factors, including, but not limited to, education, experience, knowledge, skills, and geography. Base salary does not include other forms of total compensation such as bonus compensation and other benefits.

Our benefits package includes medical, dental, and vision coverage, life and AD&D insurance, 20 days of paid time off, 9 sick days, and a 401(k) plan with a company match.

Voleon is a technology company that applies state-of-the-art machine learning techniques to real-world problems in finance. For more than a decade, we have led our industry and worked at the frontier of applying machine learning to investment management. We have become a multibillion-dollar asset manager, and we have ambitious goals for the future.

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, catered lunches, and more.

As a Senior Machine Learning Engineer on one of Voleon's Research teams, you will partner directly with research staff to advance our quantitative trading strategies. You will translate novel research ideas into production-quality code, build and maintain the data pipelines and modeling infrastructure that underpin our strategies, and apply your own strong mathematical intuition to solve open-ended technical challenges.

This role lives at the boundary of research and engineering. You will be expected to understand the statistical and mathematical concepts your research partners work with, contribute meaningfully to technical discussions about model design and evaluation, and ensure that the resulting systems are performant, reliable, and maintainable. You will work at the intersection of Computer Science, Mathematics, and Statistics — building high-performance tools that enable world-class research while maintaining a high engineering standard.

Responsibilities

Partner with PhD researchers to design, implement, and productize machine learning models that drive quantitative trading strategies

Develop and maintain complex data pipelines, including data ingestion, feature engineering, validation, and quality monitoring

Translate research prototypes and novel ideas into performant, well-tested, production-ready code

Build extensible tools and frameworks that accelerate the model development and experimentation lifecycle

Supervise, understand, and remediate subtle data quality issues across both research and production environments

Proactively lead projects from requirements through delivery, making autonomous decisions about scope, dependencies, and trade-offs, with an emphasis on long-term maintainability

Coordinate and contribute to deployment efforts while guiding junior engineers and researchers; align with research and engineering stakeholders on ownership, execution, and prioritization

Foster engineering consistency, standards, and best practices within Research

Requirements

Bachelor's degree (or higher) in Computer Science, Applied Mathematics, Statistics, or a related quantitative field

5+ years of professional software engineering experience, with strong CS fundamentals (data structures, algorithms, systems design)

Demonstrated mathematical maturity — comfort with the concepts and notation used in statistics, linear algebra, optimization, and probability

Deep proficiency in Python; experience with R and or C/C++ is a strong plus

Extensive experience with numerical and data science libraries (e.g., NumPy, Pandas, SciPy, scikit-learn, PyTorch, TensorFlow, or similar)

Proven experience building or maintaining machine learning systems in a distributed computing environment

Proficiency developing in a Linux environment with attention to performance, correctness, and reproducibility

Exceptional attention to detail, particularly when working with imperfect or heterogeneous data

Strong verbal and written communication skills, and the ability to collaborate effectively with researchers whose primary expertise is not software engineering

Preferred Qualifications

Experience with experiment management, model evaluation pipelines, or ML workflow orchestration

Familiarity with modern ML/AI infrastructure patterns (model serving, feature stores, distributed training)

Experience with performance profiling and optimization of numerical or modeling code

Prior exposure to financial data, time-series analysis, or quantitative research environments
