We're working with a financial technology business on a strategic data platform programme and are looking for a Senior C# / Snowflake Engineer to join a highly technical team delivering a business-critical initiative.

This project is focused on making large volumes of portfolio, trade and investment data more accessible across the business and to leading hedge fund clients through a modern Snowflake-based architecture.

The Role Working closely with technology teams, portfolio managers, traders and quantitative stakeholders, you'll play a key role in building and enhancing the platform used to manage and distribute complex financial datasets.

  • Collaborate with front-office, operations and technology stakeholders.
  • Contribute to the long-term evolution of the firm's data platform.
Requirements Essential
  • Strong commercial C#/.NET development experience.
  • Hands-on Snowflake experience.
  • Experience working with large-scale data platforms and datasets.
  • Strong SQL and database knowledge.
  • Experience integrating data between multiple systems.
  • Financial services experience.
  • Ability to engage directly with business and technical stakeholders.
Highly Desirable
  • Asset Management, Hedge Fund or Front Office Banking experience.
  • Portfolio, Trade, Risk or Market Data exposure.
  • Python experience.
  • Experience working alongside Portfolio Managers, Traders or Quants.
  • Cloud and modern data architecture experience.
The Environment
  • Strategic standalone programme.
  • Direct interaction with business stakeholders and hedge fund clients.
  • Small, highly capable delivery team.
  • Significant visibility and ownership.
  • Opportunity to influence the future direction of Coremont's data platform.
Details
  • Contract Length: 9 - 12 Months
  • Day Rate: Up to £1,000/day
  • Location: London
  • Working Pattern: 3-4 Days Per Week Onsite
  • Start: ASAP
If you're a strong C# Engineer with genuine Snowflake experience and a background working with financial data, we'd be keen to hear from you.
