Duration: 6+ Months of Contract with Possible Extension
Location: Waltham, MA – Onsite
Note : Need to have a minimum 12+ Years of experience and there should be a portfolio must.
Roles and Responsibilities:
- Execute high-quality UI design across multiple active web and mobile projects, working within and contributing incremental enhancements to an established design system
- Partner with design leads to translate strategic direction into polished, production-ready components, screens, and prototypes.
- Build on existing component libraries — contributing new patterns that align with established conventions
- Create wireframes and prototypes at appropriate fidelity levels to communicate design intent to developers and stakeholders
- Apply UX fundamentals (user flows, IA, usability) to inform UI decisions
- Manage concurrent workstreams, surface blockers early and maintain steady output
- Participate in design reviews, incorporate feedback and iterate efficiently
- Support handoff and design QA, ensure developer alignment with final specs
Skills & Experience
- Demonstrated senior-level execution in production environments. Portfolio should show visual craft, as well as fluency with systems and component-level thinking.
- Expert-level Figma skills: components, variants, auto layout, prototyping, and working within a mature design system
- Experience designing for both adaptive web and native mobile
- Familiarity with accessibility standards (WCAG 2.x)
- Self-directed and organized, able to maintain momentum across multiple workstreams
- Communicates clearly and proactively; responsive to feedback and shifting priorities
Portfolio Requirements:
· Portfolio work should demonstrate senior-level UI execution within a structured design environment. Specifically, we want to see:
Design system contribution
· Examples of extending or building upon an existing component library: new variants, pattern additions, or documentation.
High-fidelity UI screens
· Polished, production work across web and/or mobile. We're evaluating visual craft, typographic and spacing decisions, and consistency across screens, not just wireframes or flows.
Prototypes
· At least one interactive prototype demonstrating transitions, states, or interaction logic relevant to the project context.
Iteration examples
· Work showing how you responded to feedback or constraints from a lead or stakeholder. We want evidence of collaborative execution, not just independent creative direction.
