SOFTWARE DEVELOPMENT: Designs and implements robust trading systems, applying appropriate technologies to write clean, efficient and maintainable code, integrating market data feeds from financial providers and exchanges to process real time data and customizing solutions to align with trading strategies and regulatory requirements.

· AUTOMATION: Implements continuous integration and deployment pipelines to streamline trading software releases, automates complex tests to validate software reliability under various market conditions and optimizes workflows by automating repetitive tasks to increase operational efficiency.

· COLLABORATION: Collaborates with traders, analysts, and other cross functional teams to gather requirements and deliver needed solutions, ensuring technical solutions aligned with business goals, participates in agile practices like standups and sprint planning for effective communication, shares knowledge through code reviews to drive learning and best practices, and explains technical concepts clearly to nontechnical team members.

· TESTING & DEBUGGING: Develops comprehensive test plans, including unit and integration tests, to validate functionality and performance, applying advanced debugging skills to resolve software defects and maintain system integrity, performing complex testing to ensure the system handles high transaction volumes, and collaborating with quality assurance teams members to ensure software meets standards before deployment.

· CONTINUOUS IMPROVEMENT: Sustains the commitment to improving system performance, scalability and reliability to ensure systems evolve with changing needs, staying current with industry trends and best in class standards, proactively suggesting improvements to development processes and tools, and integrating users and stakeholders feedback to refine software solutions.

· DOCUMENTATION: Reviews and builds technical documentation of complex system architecture and development processes, ensuring clear technical guides and operation manuals to facilitate ease of use, maintaining compliance with regulations and policies, and collaborating to build the knowledge base for delivering onboarding and training new team members.

· TECHNICAL SUPPORT: Monitors live trading systems for optimal performance, including addressing complex real time issues promptly, responding quickly to resolve operational problems, minimizing downtime and risk, executing routine maintenance to keep systems secure and efficient, and developing disaster recovery planning to ensure business continuity during system failures or crises

Qualifications

This is a senior software engineering role focused on building bespoke solutions for a trading environment. The areas below reflect our existing applications and Digital Technology & Data (DT&D) engineering guidance and expectations.

· SOLUTION ENGINEERING: Strong hands-on experience building React single-page applications with TypeScript, JavaScript, HTML and CSS, using Vite. Develops reusable components, routing, forms and data visualizations, and delivers accessible, responsive interfaces with reliable state management, API integration and strong browser performance.

· SOFTWARE ENGINEERING AND INTEGRATION: Designs maintainable, modular software and well-defined service interfaces, including REST APIs, gRPC services and event-driven messaging (Kafka, AWS SQS and SNS), with clear contracts and secure authentication and authorization. Works across services and data platforms, including existing C#/.NET applications and Python and SQL integrations with Oracle and Snowflake. Applies sound design, debugging and refactoring practices when modernizing existing applications.

· QUALITY AND DELIVERY: Uses Git and GitHub for collaboration and code review. Builds automated unit, component, integration and end-to-end tests, and applies linting, dependency management and security checks. Experience with CI/CD, Docker, deployment automation in AWS, identity services and Datadog observability is valuable.

· AI IN SOFTWARE DEVELOPMENT: Uses AI coding assistants (GitHub Copilot, Claude Code, Codex) as a productivity multiplier across the development lifecycle, while holding generated code to the same standards as hand-written code. Can explain and defend any AI-assisted change, works only through Cargill-provisioned access, and never compromises confidential information.

· SENIOR ENGINEERING CONTRIBUTION: Independently delivers features from design through production support, explains technical trade-offs, mentors colleagues and improves shared engineering practices. Brings practical delivery experience and the ability to learn Cargill platforms and standards quickly.
