OVERVIEW:
Builds and maintains a shared front-end design system (component library and supporting tooling) used across the Bank’s web applications. This role focuses on TypeScript-based component engineering, Node.js-powered build/test/release pipelines, accessibility and quality standards, and enablement of internal product teams through documentation and support.
Primary Responsibilities:
* Engineer and evolve a shared design system and component library using TypeScript, including reusable UI components, patterns, and utilities.
* Translate approved UX/UI designs and interaction specifications into robust, accessible components in partnership with designers and product engineers.
* Develop and maintain Web Components (custom elements) and related standards-based patterns to support consistent, framework-agnostic adoption across consuming applications.
* Champion and apply accessibility (a11y) standards for the library (semantic markup, keyboard/focus behavior, appropriate ARIA), and support consuming teams with guidance and reviews.
* Develop and maintain the library ecosystem, including documentation, usage guidelines, examples, and developer enablement materials.
* Build and operate Node.js-based tooling for the library (build, test, lint, packaging, and publishing) and support CI/CD automation.
* Adhere to established quality practices for the design system: automated unit/integration tests, visual/regression testing where applicable, and code review standards.
* Support versioning and release practices for internal consumers (e.g., semantic versioning, change logs, deprecation strategy) to enable safe adoption.
* Support internal users of the design system by troubleshooting integration issues, triaging defects, and improving developer experience (DX).
* Collaborate with product, design, QA, and other engineering teams to understand needs, prioritize backlog, and drive alignment on shared UI standards.
* Understand and adhere to the Company’s risk and regulatory standards, policies, and controls; escalate risk-related issues as needed.
* Promote an environment that supports a culture of belonging and reflects the M&T Bank brand.
* Maintain M&T internal control standards, including timely implementation of internal and external audit points together with any issues raised by external regulators as applicable.
* Complete other related duties as assigned.
Education and Experience Required:
* Associate’s degree and a minimum of 5 years’ systems analysis and/ or application development work experience or Bachelor's degree and a minimum of 3 years’ systems analysis and/ or application development work experience. In lieu of degree, a combined minimum of 7 years’ education and/or relevant work experience, including a minimum of 3 years’ systems analysis and/or application development work experience.
* Professional experience engineering reusable front-end components using JavaScript/TypeScript.
* Experience with Node.js and front-end build tooling to support packaging, testing, and publishing (e.g., CI pipelines).
* Experience with code quality practices such as reviews, automated testing, and continuous integration.
* Advanced proficiency with at least one modern front-end framework (Angular, React, Vue, Solid, Svelte, or Lit).
Education and Experience Preferred:
* Deep experience implementing and validating accessible component behavior (a11y) and familiarity with WCAG concepts.
* Experience with design system tooling (e.g., Storybook or similar) and maintaining high-quality component documentation.
* Familiarity with Figma design handoffs (e.g., consuming component specs, tokens, and interaction guidance) and collaborating with designers to clarify implementation details.
* Hands-on experience with Angular, React, and Lit in a component-library or design-system context.
* Familiarity or hands-on experience with Web Components (custom elements; Shadow DOM concepts) and how to integrate them with common frameworks.
* Experience publishing and maintaining internal packages (versioning, release notes, deprecation strategy) for multiple consuming teams.
* Experience with monorepos and modern build tooling (e.g., package managers, bundlers, linters) and improving developer experience (DX).
* Experience working in an Agile team environment.
* Ability to work autonomously and to multitask on complex projects.
* Strong organizational and time management skills.
