SUMMARY

We are looking for a thoughtful and detail-oriented UI/UX Product Application Designer with 7+ years of professional experience to help shape intuitive, elegant, and user-centered B2B digital experiences.

You will play a key role in turning complex problems, often involving data, calculations, dashboards, and system integrations, into clear, step-by-step workflows that balance user needs, business goals, and technical feasibility.

As part of a cross-functional team, you’ll work closely with product managers, engineers, stakeholders, and end users to define requirements and rapidly move from idea to prototype using Figma (including prototyping) and modern AI-enabled design tools.

If this sounds like the right role, please submit a resume along with a link to a portfolio showcasing product application design.

ESSENTIAL DUTIES & TASKS

• Translate product requirements into user flows, wireframes, clickable prototypes, and high-fidelity mockups in Figma for desktop and mobile product experiences.
• Show curiosity and drive in adopting new AI tools and workflows (including integrations) to accelerate iteration and move from idea to prototype quickly.
• Create clear specifications, annotations, and acceptance criteria to support developer handoff, including front-end behaviors and high-level back-end requirements (data, integrations, and system rules).
• Design for complex integrations and ensure solutions are feasible, scalable, and consistent, backed by strong information architecture and systems thinking.
• Demonstrate the ability to think independently and collaborate with cross functional team members to develop and refine internal processes and ensure efficiency across workflows.
• Conduct user research (interviews, surveys, usability tests) to inform design decisions.
• Translate complex business needs into intuitive, step-by-step user experiences and functional UI requirements, including rules, validations, calculations, and edge cases.
• Build and maintain design systems and reusable components to ensure visual consistency.
• Collaborate with developers to ensure pixel-perfect implementation and responsive design.
• Iterate on feedback from users, stakeholders, and team members.
• Advocate for best practices in accessibility, design systems, and interaction design
• Analyze usage data and conduct testing to continuously improve the product experience, including data-heavy screens (charts, graphs, dashboards, and reporting workflows).

QUALIFICATIONS

• 7+ years of experience in UI/UX, product design, or similar roles.
• Strong portfolio showcasing user flows, wireframes, high-fidelity UI, and final products.
• B2B product experience designing workflow-driven applications where clarity, efficiency, and accuracy matter.
• Experience designing for both desktop and mobile applications, including experiences with complex integrations and multi-step processes.
• Proficient in Figma, including interactive prototyping, and comfortable using modern AI-enabled design tools to document, communicate, and iterate on designs and requirements.
• Experience working with design systems and component libraries.
• Strong problem-solving skills with demonstrated ability to simplify complex problems into usable, elegant experiences.
• Solid understanding of design principles, typography, color theory, data visualizations, and responsive design.
• Experience designing data-heavy UX (analytics, dashboards, charts/graphs, and calculation-driven interfaces) with strong attention to detail and QA-mindedness.
• Effective communication and collaboration skills.

Nice-to-Have:

• Familiarity with user research methodologies and usability testing.
• Experience working in Agile/Scrum teams.
• Familiarity with front-end technologies (HTML, CSS, JavaScript) is a plus.

What You’ll Gain

• Opportunity to shape real-world product experiences that make a difference.
• A collaborative, data-driven, and user-focused product team.
• Exposure to a fast-paced, iterative development environment that embraces AI.
