Lead Software Developer (OMS/EMS) - Leading Tier 1 Hedge Fund - Discrete Search - Excellent Compensation + Benefits

My client, a leading global hedge fund, is seeking their first engineering hire within their London office to lead the built out of their global OMS.

This is a rare opportunity to sit close to the business-Portfolio Managers, Traders, Compliance, Treasury, and Trade Operations-owning technology that powers the full trade lifecycle from origination through warehousing.

You'll lead the design and delivery of scalable, business-critical applications that augment vendor OMS/EMS and integrate with bespoke systems for treasury, compliance, and trade ops. Expect a modern stack (SQL Server, Snowflake, AWS, Angular/React) and a fast-paced environment where your engineering decisions directly shape a multi-asset trading platform.

Key responsibilities will include:

• Architecting and building trade-flow applications & reporting tools: You'll design and deliver resilient services that streamline order capture, routing, compliance checks, allocations, warehousing, and end-of-day processes-integrating vendor OMS/EMS with in-house platforms.
• Enhancing and extending OMS/EMS workflows across asset classes: You'll tailor and extend vendor functionality, close gaps with custom augmentations, and ensure seamless data and workflow integration across trading, compliance, treasury, and trade operations.
• Partnering directly with front-office and operations stakeholders: You'll work hand-in-glove with PMs, traders, ops, and tech leadership to define requirements, iterate quickly, and ship solutions that improve speed, control, and transparency.
• Modernising the platform and establishing best practices: You'll drive cloud migration (AWS, Snowflake), uplift data models and pipelines, and set engineering standards around reliability, observability, testing, and performance-guiding junior engineers along the way.
• Owning production quality and support: You'll provide escalation-level coverage for mission-critical OMS/EMS platforms during market hours and EOD, helping keep the trade lifecycle running smoothly globally.

They are seeking candidates with:

• 10+ years' OMS/EMS experience building and supporting order/execution workflows.
• Strong hands-on skills in C# or Python, advanced SQL, and solid foundations in data structures, memory management, and concurrency.
• Experience with AWS/Snowflake and modern UI frameworks (Angular/React/Vue).
• Excellent stakeholder communication and the ability to translate complex ideas into clear, actionable plans.
• Comfort balancing project delivery with production support in a fast-moving environment.
• Bonus: knowledge of Equities, Fixed Income, Options, Futures and pragmatic use of AI tools to accelerate the SDLC.

My client anticipates to pay a strong performer upwards of £300k 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.
