Senior Design/Developer

We are seeking a Senior Design/Developer to act as the design and front-end technical lead for client facing Portals. 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.

What you can expect from us?

• Contract Stability
• High level of autonomy and independence
• Senior role: The chance to act as a Senior Design / Developer
• Participation in key projects
• International collaboration: Building and cultivating partnerships across various business regions

Employment agency entry number 47

this job offer is intended for people over 18 years of age

What will your tasks involve?

• 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 TA Portal 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.

What we expect from you?

• Expert-level proficiency in design/prototyping tools (e.g., Figma), including

component libraries and design systems.

• Strong hands-on 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.

• Nice-to-Have: 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.
