Job description

I’m working with a leading systematic hedge fund in New York that is seeking an elite C# Developer to join its Risk Development team in London.

This is a front-footed technical role in one of the most business-critical engineering groups in the firm – focused on designing and scaling cutting-edge risk systems that power real-time and historical analytics for PMs, risk officers, and senior leadership.

As part of this team, you’ll be building foundational components to support stress testing, equity factor models, VaR, risk decomposition, and analytics tooling. You’ll also contribute to scaling the firm’s large-scale data systems and driving modernization efforts across risk technology.

You'll work in a highly technical environment using Python and have the opportunity to contribute to high-performance architecture, cloud-based data platforms (AWS, Snowflake, Redshift), and streaming technologies (Kafka).

Responsibilities

• Design and build scalable systems for risk analytics, stress testing, VaR, and multi-factor risk modeling across asset classes.
• Develop and maintain high-performance services in an OOP language, with strong focus on clean architecture and modular design.
• Own the full lifecycle of solutions from conception to deployment, including data storage, transformation, analysis, and visualisation.
• Collaborate with risk managers, PMs, and other engineering teams to deliver production-grade risk tools and analytics.
• Drive innovation within risk infrastructure, leveraging modern technologies to modernize data processing and enhance system resiliency.
• Provide Level 3 production support for global users and continuously iterate based on business feedback.

Requirements

• Expertise in Software development, with deep understanding of software design principles and system architecture.
• Strong experience with relational databases and data modelling for large-scale analytical applications.
• Background in risk technology or quantitative engineering within the financial services industry.
• Excellent written and verbal communication skills; able to translate technical ideas into actionable business value.
• Proven track record of ownership and delivery in high-performance, high-stakes environments.

My client anticipates to pay a strong performer upwards of $400k year 1 total compensation package. As well as a market-leading compensation package, they offer exceptional benefits including a top-tier healthcare package, fully subsidised qualifications plus breakfast and lunch paid for each day.
