Python Software Engineer

The Role

Weiss Asset Management is seeking a skilled Python Developer to design, build, and maintain the software infrastructure that supports our quantitative analysts and investment professionals. This person will develop robust, scalable tools and systems that enable research, portfolio analysis, and quantitative strategy development.

The ideal candidate has strong software engineering fundamentals and understands how well-designed technology can enhance investment research. You will work closely with quantitative developers, analysts, and other stakeholders to deliver high-quality, maintainable solutions that advance our technical capabilities and streamline analytical workflows.

This is a hands-on engineering role focused on building and improving the tools and platforms that support our investment process. While it does not directly involve leveraging agentic AI systems, machine learning and data analysis, your work will directly enable development in these areas.

Many of our solutions stem from jumping in with users on technical issues that arise throughout the research and development process. In some case, you may provide a quick fix, in others we may wish to take a step back and look at the problem in a broader context.

The Team

We enjoy problem solving with domain experts across a multi-strategy enterprise. We apply powerful patterns and tools to form a seamless and opinionated way of working that is easy for new and existing users to adopt.

Responsibilities

• Design, develop, and maintain Python-based systems to support quantitative research and investment analysis
• Collaborate with stakeholders to understand objectives and deliver solutions aligned with our technical roadmap
• Engage regularly with technical counterparts on the investment team to develop coherent solutions that leverage core systems
• Improve the architecture, performance, and reliability of existing systems
• Enhance monitoring, automation, and CI/CD workflows to increase efficiency and platform stability
• Establish and document design standards and promote best practices across development teams
• Contribute to technical recruiting, onboarding, mentorship, and code reviews for analysts, interns, and developers
• Communicate effectively with both technical and non-technical stakeholders

Qualifications

• 5+ years of professional experience in Python software development
• Strong understanding of software architecture, design principles, and package management
• Experience developing libraries or tools for use by other developers in production environments
• Excellent communication and collaboration skills with a strong customer-focused mindset
• Familiarity with SQL, Spark, Databricks, and Data Science libraries such as pandas and numpy preferred
• Experience with Agile software development and tools such as JIRA, Confluence, and CI/CD pipelines
• Exposure to financial markets and experience working with quantitative or investment teams is preferred
