Trading Platform Engineer – Core Trading Systems - C# Development - Global Multi-Asset Investment Firm - London - Up to £400k TC


Our client is a globally recognized, multi-asset investment firm managing over $25 billion in assets on behalf of a major philanthropic foundation and select institutional partners. Operating as both a family office and institutional-grade asset manager, the firm combines the long-term perspective of permanent capital with the agility to act decisively when opportunity arises.


With a presence across New York, London, Greenwich, and Dublin, the firm invests across asset classes — including public and private equity, credit, fixed income, FX, and alternatives — through a flexible, unconstrained mandate. Its professionals are united by an entrepreneurial culture that values intellectual rigor, collaboration, and innovation. The firm emphasizes ownership, development, and accountability, empowering individuals to think creatively, challenge assumptions, and build systems that drive real performance impact.


The Opportunity

We are seeking a Software Engineer to join the firm’s Core Development team, which builds and supports the technology platform that powers the full trade lifecycle — from order creation and execution to post-trade operations.


In this role, you’ll work directly with traders, portfolio managers, and operations teams to design and implement scalable systems supporting multi-asset-class trading. You’ll develop and enhance integrations between vendor OMS/EMS platforms and proprietary in-house applications, contributing to the firm’s strategic modernization of its trading infrastructure.


This position offers hands-on exposure to complex trading systems, modern cloud technologies, and a collaborative, high-performance environment where technology is viewed as a strategic differentiator.


Key Responsibilities

* Design, build, and maintain trade flow and operations systems supporting order management, execution, and compliance across multiple asset classes.
* Integrate and extend vendor OMS/EMS platforms, developing custom augmentations and bespoke tools for trading, treasury, and compliance workflows.
* Collaborate closely with traders and operations teams to deliver user-centric, high-performance applications.
* Contribute to the modernization of legacy systems by migrating infrastructure to AWS and Snowflake, improving scalability and maintainability.
* Develop solutions using C#, Python, SQL Server, and cloud-native tools, alongside modern UI frameworks such as React or Angular.
* Provide ongoing production support for mission-critical systems during trading hours and end-of-day processes.
* Work with senior developers to define best practices and implement components of a unified, scalable trade platform.


Ideal Candidate Profile

* 5–10 years of experience developing and supporting Order Management (OMS) and Execution Management Systems (EMS).
* Strong proficiency in C# or Python, with advanced SQL and database design expertise.
* Hands-on experience with AWS, Snowflake, and modern software architecture.
* Solid grasp of data structures, concurrency, and memory management.
* Experience developing responsive, performant UIs using React, Angular, or Vue.js; familiarity with PowerBI or other BI tools is a plus.
* Effective communicator capable of working directly with business users and senior stakeholders.
* Adaptable and collaborative mindset, thriving in a fast-paced, agile environment.
* Familiarity with multi-asset trading (Equities, Fixed Income, Options, Futures) preferred.
* Interest in leveraging AI-assisted tools to enhance the development lifecycle.


Why This Role

* Be part of a high-caliber engineering team powering a global multi-asset trading platform.
* Work closely with investment professionals, driving technology that directly impacts trading efficiency and performance.
* Join a culture that values innovation, autonomy, and continuous improvement.
* Competitive compensation, world-class resources, and long-term professional growth opportunities.
