About the Role
We have an exciting and rewarding opportunity for you to take your software engineering career to the next level. As a Software Engineer III in the Securities Services team within the Commercial & Investment Bank, you will design and deliver secure, scalable technology products that drive business success. You will build and evolve a shared frontend platform and reusable UI patterns, focusing on performance, accessibility, and developer experience. This is a pure frontend position with a strong AI focus: you will help deliver AI-enabled user experiences and accelerate engineering velocity by responsibly using modern AI developer tools such as AI-assisted coding, debugging, and test generation, while maintaining a high bar for correctness, security, and quality.

Your work will directly impact our customers and the way we build technology. You will design, develop, and troubleshoot creative software solutions for technical challenges, write secure, high-quality production code, and maintain UI logic that integrates with shared platforms. You will develop and maintain reusable React components and UI patterns for complex workflows, build high-performance, data-intensive user interfaces using profiling and optimization techniques, and engineer accessible, inclusive experiences by partnering with UX and design teams.

Additionally, you will write and maintain automated tests (unit, integration, end-to-end) to ensure reliability and quality. Collaborating closely with UX designers, product stakeholders, and developers, you will build custom UI components and develop tools and automated processes to streamline development and enhance developer experience.

You will leverage enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity across complex deliverables, validating outputs through peer review, automated testing, and secure coding standards. You will contribute learnings and reusable patterns to improve broader team effectiveness and apply knowledge of tools within the Software Development Life Cycle toolchain, including AI-assisted development and automation capabilities, to maximize automation value.

Building Generative AI interface solutions using React and TypeScript following CI/CD standards will be a key part of your role. You will actively use AI development tools for code generation, refactoring, debugging, documentation, and testing, working closely with Product, UX, and cross-functional partners to deliver capabilities in agile sprints.
