Job description

Our client is a leading global multi-strategy investment firm with a technology-first approach and a genuinely high-performance engineering culture.

With a global footprint spanning New York, Houston, London, Singapore and Hong Kong, the firm operates at significant scale across markets, strategies and regions.

They are now looking to add a Python Hedge Fund Developer to their New York engineering team, working closely with Treasury and other business functions to build technology that supports cash management, liquidity, funding and wider treasury operations.

The Opportunity

This is a hands-on full-stack engineering role where you’ll have ownership from design through to delivery.

You’ll work across Python, React, APIs, SQL and modern cloud/data technologies, building applications and services that automate and improve critical Treasury workflows.

It’s an opportunity for an engineer who enjoys working across the stack, solving complex problems and operating at the intersection of technology, data and financial markets.

• Develop APIs and backend services supporting cash management, liquidity and funding workflows


• Work with Snowflake and AWS RDS, alongside relational databases


• Design and deliver scalable applications that improve automation and operational efficiency


• Collaborate closely with Treasury, Product, Data and Engineering teams

Experience within Treasury, Finance, Capital Markets or an investment environment would be advantageous, but isn't essential.

What You’ll Get

• The opportunity to work within a high-performing global investment firm


• Genuine ownership across both technical delivery and business-facing projects


• Exposure to Treasury, financial markets, data and automation


• A modern technology environment spanning Python, React, AWS, Snowflake and PostgreSQL
