Full Stack Software Engineer

The New York Stock Exchange (an Intercontinental Exchange company) is looking for a versatile Full Stack Software Engineer to work across the entire stack, from data and services through to the user experience. The role involves owning problems from idea to production, using AI and agentic tools to accelerate development, and joining a fluid team that moves quickly.

• Design and build thoroughly tested, efficient, maintainable software across the full stack
• Own features from early concept and prototype through to production and support
• Design, build, and integrate RESTful APIs and services
• Contribute to and enhance shared component and testing frameworks
• Use AI and agentic development tools to accelerate implementation, testing, refactoring, and documentation, while retaining full ownership of the correctness, quality, security, and maintainability of everything shipped
• Review and validate code generated by AI with the same rigor as any other change, and define the conventions and guardrails that keep this work consistent with the codebase
• Choose an appropriately sized AI model for each task, balancing capability against speed and cost
• Create and maintain clear software documentation
• Prepare and produce releases of software components
• Build wireframes and prototypes to validate ideas quickly
• Provide support throughout the software delivery process, including beyond business hours when necessary

• Bachelor's degree in Computer Science or a related field, or equivalent practical experience
• 2 or more years of professional software development experience
• Strong computer science fundamentals, including data structures, testing, debugging, and clean, maintainable design
• Proven ability to work across the full stack, comfortable on both the frontend and the backend rather than in a single layer
• Proficiency with a modern frontend framework and the core web technologies beneath it, including component design and state management. We primarily use React and TypeScript, with JavaScript, HTML5, and CSS
• Experience building backend services and integrating RESTful APIs
• Experience working with a relational database such as Oracle or PostgreSQL
• A habit of writing automated tests and reviewing code with care, including code produced by AI
• Demonstrated, recent experience using AI development tools (see Working with AI above)
• Excellent communication skills and the ability to explain technical solutions clearly
• Ability to work well both independently and as part of a team, with a strong desire to grow

• healthcare coverage (medical, dental and vision)
• 401(k) plan
• life insurance
• time off
• paid leave for qualifying circumstances
