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.
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.
