With $28 billion in assets under management (AUM), SFM serves as the principal asset manager for the Open Society Foundations, one of the world’s largest charitable foundations dedicated to advancing justice, human rights, and democracy.

Distinct from other investment platforms, SFM thrives on agility, acting decisively when conviction is high and exercising patience when it’s not. With permanent capital, a select group of major clients, and an unconstrained mandate, we invest opportunistically with a long-term view in a wide range of strategies and asset classes, including public and private equity and credit, fixed income, foreign exchange, and alternative assets. Our teams operate with autonomy, while cross-team collaboration strengthens our conviction and empowers us to capitalize on market dislocations.

At SFM, we foster an ownership mindset, encouraging professionals to challenge the status quo, innovate, and take initiative. We prioritize development, enabling team members to push beyond their roles, voice bold ideas, and contribute to our long-term success. This culture of continuous growth and constructive debate fuels innovation and drives efficiencies.

Our impact is measured by both the returns we generate and the values we uphold, from environmental stewardship to social responsibility. Operating as a unified team across geographies and mandates, we remain committed to our mission, ensuring a meaningful, lasting impact.

Headquartered in New York City with offices in Greenwich, Garden City, London, and Dublin, SFM employs 200 professionals.

Team Overview

The Core Development team builds and supports the technology that powers the full trade lifecycle—from trade origination to warehousing. We work closely with Portfolio Managers, Traders, Compliance, Treasury, and Trade Operations to ensure seamless trade flow across asset classes.

Our technology stack is a blend of vendor and homegrown systems: we leverage vendor-provided Order Management (OMS) and Execution Management Systems (EMS) as the backbone of trade flow, while building custom applications that augment OMS/EMS workflows and bespoke systems to support treasury, compliance, and trade operations processes. This combination allows us to deliver both breadth and flexibility, meeting the evolving needs of the business.

We are seeking a Senior Software Engineer with deep expertise in trade flow, including Order Management Systems (OMS) and Execution Management Systems (EMS). The ideal candidate will lead the design, architecture, and delivery of scalable applications that are critical to trading, compliance, treasury, and trade operations. This role requires advanced technical leadership, strong business insight, and exceptional communication skills, as you will partner directly with traders, operations teams, and technology leadership to shape solutions that drive the firm’s multi-asset-class trading strategy.  This role will report to the Head of Trade Execution Technology.

  • Extend vendor OMS/EMS functionality by architecting custom augmentations and building bespoke systems for mission-critical workflows in treasury, compliance, and trade operations.
  • Partner with cross-functional technology and business teams to define and deliver a modern, unified, and scalable trade platform.
  • Provide technical leadership in leveraging SQL Server, Snowflake, AWS, and modern UI frameworks (e.g., Angular, React) to deliver end-to-end solutions.
  • Lead efforts to modernize legacy systems by migrating to AWS and Snowflake, establishing best practices and guiding junior team members.
  • Oversee and provide escalation-level support for mission-critical OMS/EMS platforms during market hours and end-of-day processes, with flexibility for global team coverage.
  • Translate complex technical concepts into clear communication for senior stakeholders, influencing technology strategy and decision-making.

What We Value  

  • OMS/EMS Experience: 10+ years hands-on development and support of Order Management and Execution Management Systems.
  • Technical Excellence: Proficiency in one or more programming languages (C#, Python) and advanced SQL skills; hands-on experience with AWS and cloud-native development; solid grounding in data structures, memory management, and concurrency.
  • UI Skills: Ability to build intuitive and performant UIs with frameworks such as Angular, React, or Vue.js. Familiarity with PowerBI or similar business intelligence reporting tool is helpful.
  • Data Expertise: Strong background in SQL Server and cloud platforms (Snowflake, Databricks).
  • Collaboration & Communication: Ability to partner directly with traders, operations, and other business teams, and to explain complex ideas clearly.
  • Adaptability: Comfort working in a fast-paced environment, balancing project delivery with production support.
  • Preferred: Knowledge of asset classes such as Equities, Fixed Income, Options, and Futures; effective use of AI tools to improve the development cycle.

We anticipate the base salary of this role to be between $180K-230K. In addition to a base salary, the successful candidate will also be eligible to receive a discretionary year-end bonus.
