Job description

Senior Developer / Lead Architect – Systematic Hedge Fund

Senior Developer / Lead Architect – Systematic Hedge Fund

Tech Stack: Python, C#/.NET, Azure, SQL Server, Azure DevOps A growing systematic hedge fund is looking to hire a senior-level technologist to support the development of its trading and research infrastructure. The firm is expanding its technology capabilities and building out a small, high-impact team. This hire could either be a Senior Developer ready to grow into a broader leadership role or an experienced Technical Architect with proven delivery experience in financial markets.

The ideal candidate will be hands-on, pragmatic, and capable of balancing strategic design with day-to-day development. This is not a management-heavy role; the team is lean, so the ability and willingness to code daily is essential. Experience working at a mid-sized hedge fund or asset manager is strongly preferred.

Responsibilities:

• Design and build data pipelines to ingest and process large volumes of financial data from various vendors
• Collaborate with researchers and traders to develop and support high-performance trading systems
• Develop monitoring tools and dashboards to ensure system stability
• Lead the adoption of best practices in software development, testing, and deployment
• Provide mentorship and guidance to junior developers as the team grows
• Take a lead role in shaping the firm’s technical architecture and infrastructure strategy

Requirements:

• 5+ years of experience in Python or C# development within financial services (ideally hedge funds)
• Strong experience with data engineering, ETL pipelines, and SQL databases
• Familiarity with modern DevOps practices including CI/CD, version control, and containerization
• Experience with cloud services (Azure preferred, but open to others)
• Demonstrated ability to work in small teams and take ownership of critical systems
• Strong academic background in computer science, engineering, or a related field

This is an exciting opportunity to make a tangible impact within a growing fund. The team is lean and performance-driven, offering exposure to both the trading floor and senior leadership. Ideal for someone looking to step up into a broader technical leadership role without giving up hands-on coding.
