Job Description
We are seeking a Senior Design/Developer to act as the design and front-end technical lead. This is a hybrid role combining UX ownership (requirements-to-prototype, design system governance) with hands-on senior front-end engineering leadership. The ideal candidate translates ambiguous business requirements into validated, high-fidelity prototypes, then leads (and codes alongside) the mid-level development team to deliver pixel-accurate, accessible, enterprise-grade portal experiences.
Key Responsibilities
- Own the requirements-to-prototype pipeline: run discovery with business/product stakeholders, produce wireframes, interactive prototypes, and high-fidelity designs.
- Define and enforce UI/UX standards, interaction patterns, and design system usage across all applications.
- Architect and build key React/TypeScript front-end components and shared UI libraries, setting technical and design precedent for the team.
- Review pull requests and provide constructive, actionable feedback to mid-level developers on both design fidelity and code quality.
- Partner with backend/API teams to ensure front-end designs are technically feasible within service and data constraints.
- Drive accessibility compliance (WCAG 2.1 AA) and responsive design across all portal screens.
- Conduct usability testing/validation sessions and iterate designs based on user feedback and analytics.
- Mentor mid-level UI/UX developers on both design thinking and React best practices.
- Participate in architecture/design governance reviews as design owner for the portal.
- Expert-level proficiency in design/prototyping tools (e.g., Figma), including component libraries and design systems.
- Strong hands-on (14 yrs) React.js + TypeScript development experience (component architecture, state management, hooks).
- Demonstrated experience translating designs into production-quality, responsive, accessible UI.
- Familiarity with containerized application environments (Docker/Kubernetes/OpenShift) and modern CI/CD pipelines.
- Strong stakeholder management - comfortable defending design decisions to both business and engineering audiences.
- Experience reviewing code and providing technical/design feedback within a team setting.
- Working knowledge of Java or .NET (for backend collaboration/awareness - not a core build requirement).
- Experience with Micro Frontend architectures (Module Federation, single-spa).
- Basic SQL/database knowledge.
- Prior experience in financial services, fund administration, or transfer agency platforms.
