Full Job Description

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.

Proficient verbal and written communication skills.

We support our team members with generous benefits.

Competitive compensation
Health, welfare, and retirement benefits
