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.

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.

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.

• 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.
