Principal SQL Engineer

Principal SQL Engineer – Trading Desk | SQL Server, C#/.NET, Concurrent SQL environment | 25-Year Systematic Hedge Fund ~£140k-£200k circa base + bonus (up to 100%) ~ City of London, on-site Mon-Fri Our client, an algorithmic trading hedge fund with a 25-year track record in systematic trading, are hiring a Principal SQL Engineer to join their trading desk tech team. It’s a 20-person business with roughly half the team in engineering and technical roles, so you’re in a genuinely tech-led environment where trading is fully programmatic and engineers work closely with the desk day to day. They’re hiring a Principal SQL Engineer to become the lead engineer responsible for their most business-critical platform: the internal trading dashboard that sits at the centre of the desk’s day-to-day activity. You’ll work closely with traders, quantitative researchers and the Founder, helping shape how financial market data is stored, modelled, queried and surfaced across the business. A big part of the role is understanding what the business is trying to achieve with the data, then designing the right structures, workflows and tooling around it. This is not a traditional ETL or pipeline engineering role. A lot of the core business logic sits in SQL stored procedures, and the role spans both the database and application layers across SQL Server and C#/.NET systems while acting as a key link between the trading desk and wider engineering team.
