Senior Market Data Engineer (C#)

Location: London / 4 days onsite per week

About the Team:

Our client, a highly reputable multi-strat hedge fund, is offering you the chance to join a small, high-impact team responsible for the firm's full suite of market data services, including real-time trading and pricing feeds and historical/licensed datasets for analytics, risk, and reporting.

The team is undergoing a full transformation to modernise and unify market data infrastructure, moving from legacy on-prem systems to AWS.

Role Overview:

This hands-on engineering role is ideal for a senior C# developer with experience in market data. You will help shape the architecture and direction of the firm's new data warehouse and lakehouse platform, standardising ingestion from both real-time and licensed data sources, improving data consistency, and replacing manual, brittle processes (Excel macros, ad hoc scripts).

Key Responsibilities:

• Build and maintain real-time and historical market data pipelines (primarily Bloomberg/BPIPE).
• Drive the design and implementation of cloud-native data warehousing and lakehouse architecture.
• Collaborate with a small team to improve data consistency, scalability, and control.
• Influence architecture and best practices across the market data platform.

Requirements:

• Strong C# development experience.
• Hands-on experience with real-time market data systems (Bloomberg/BPIPE preferred).
• Experience with cloud-native data warehousing and data lakehouse solutions.
• Ability to work in a small, collaborative team while influencing architecture and processes.
