📍 Job Overview

Job Title: UX/UI Designer Mobile (12m FTC)

Company: Argus Media

Location: London, United Kingdom

Job Type: Full-time

Category: UX/UI Design, Product Design

Date Posted: September 23, 2026

Experience Level: 5-10 years

Remote Status: On-site

🚀 Role Summary

• Design and enhance the user experience for Argus Media's digital products across responsive web and native mobile platforms, with a strong emphasis on Flutter-based applications.

• Conduct comprehensive user research and stakeholder requirement gathering to inform design decisions and ensure user-centricity.

• Develop intuitive, scalable, and reusable design solutions, from low-to-high fidelity prototypes, leveraging AI-assisted design tools.

• Champion design quality and best practices throughout the Agile development lifecycle, ensuring seamless collaboration with product owners, product managers, and engineers.

• Actively contribute to the expansion and maintenance of design systems, component libraries, and pattern libraries, including emerging patterns for AI-assisted user experiences.

📝 Enhancement Note: This role requires a hybrid UX/UI designer with a strong focus on mobile applications, particularly those built with Flutter or similar cross-platform frameworks. The emphasis on AI-powered experiences and enterprise applications with complex user journeys indicates a need for strategic thinking and a deep understanding of user behavior in specialized domains. The fixed-term contract (FTC) nature suggests a project-driven need, likely for a significant product development phase or initiative.

📈 Primary Responsibilities

• Own the user experience strategy and execution for a portfolio of Argus Media's digital products, ensuring consistency across responsive web and native mobile interfaces.

• Create compelling user journeys, wireframes, mock-ups, and interactive prototypes for both Flutter-based applications and responsive web designs, catering to Android and iOS platforms while aligning with enterprise desktop applications.

• Lead user research initiatives, including planning, conducting, and analyzing usability testing sessions (remote and on-site), to gather actionable insights and validate design concepts.

• Collaborate closely with cross-functional teams, including product owners, product managers, and engineers, to translate complex requirements and user stories into effective design solutions.

• Ensure adherence to UX best practices, usability principles, and WCAG accessibility guidelines throughout the design and development process.

• Facilitate design workshops and brainstorming sessions to foster collaborative ideation and drive consensus on initial design concepts and wireframes.

• Provide clear design handovers to development teams, meticulously review implemented designs, identify and raise defects, and actively participate in resolving technical issues.

• Define and evolve interaction models, continuously evaluating their success and iterating based on user feedback and performance data.

• Contribute to the development and maintenance of comprehensive design systems, including component libraries, pattern libraries, and documentation, with a forward-looking approach to AI-assisted user experiences.

• Represent the UX function effectively across various teams and products, advocating for user-centric design principles and best practices.

📝 Enhancement Note: The responsibilities highlight a hands-on design role with significant strategic input. The expectation to "champion design quality" and "represent the UX function" suggests a senior individual contributor who can influence product direction. The mention of "enterprise applications with complex user journeys for specialised domains" points towards a need for experience in B2B or highly regulated industries, demanding a robust understanding of intricate workflows and data.
