Job Description

Mission Overview:

Join the Service & Delivery Management (SDM) team at Keystone Solutions, where you will be part of a cross-functional UX Expert Pool. This consultancy mission involves working on various digital projects to design simple, effective, and user-centered services.

As a consultant, you will engage in multiple business projects simultaneously, collaborating closely with project managers, analysts, and development teams from the early phases throughout the project lifecycle.

Your responsibilities will include conducting user research activities (interviews, analyses, workshops) to understand the needs, constraints, and expectations of users.

You will structure user journeys and formalize UX deliverables (personas, user journeys, flows) to guide the design process.

Additionally, you will create wireframes and prototypes to quickly visualize solutions and facilitate discussions with stakeholders.

Facilitating co-design workshops to align business, IT, and user visions will also be part of your role.

You will organize and conduct user testing to validate hypotheses and iteratively improve solutions.

Working in an agile mode, you will actively participate in project rituals.

Ensuring the quality and consistency of the user experience in line with UX standards and the organization's design system will be crucial.

Finally, you will contribute to disseminating UX best practices and sharing expertise within the UX pool.

Requirements:

• User empathy: ability to understand users' needs, expectations, and frustrations.
• Excellent communication: ability to convey ideas clearly, structured, and tailored to the audience.
• Synthesis skills: ability to simplify complex issues into clear and actionable messages.
• Collaborative spirit: ability to work effectively with diverse profiles (business, IT, management).
• Critical thinking: ability to question assumptions and challenge proposed solutions.
• Proactivity: ability to take initiatives and propose concrete improvements.
• Adaptability: ability to quickly adjust to project constraints and changes.
• Results orientation: ability to aim for a concrete and measurable impact on user experience.

Evaluation Method:

Offers will be evaluated in three stages:

• Verification of elimination criteria: any candidate not meeting the KO criteria will be dismissed.
• Qualitative profile evaluation: analysis of the CV and supporting elements (portfolio, experiences); any unproven element will be considered unacquired.
• Interview (if applicable): to validate skills, autonomy, and fit for the project context.
