At MindWave we’re not just building teams. We’re building a new way of working with an international community of experts who thrive in an innovative and people-first environment.

For a key player in the European energy transition, we are looking for a Senior UX Researcher to bring the user perspective into a portfolio of digital platforms-from initial discovery and research to interaction design and validation.

In this role, you will work across customer-facing portals, developer and API platforms, and internal back-office tools, creating seamless journeys for energy-market stakeholders and contributing to a sustainable, reliable energy landscape.

Your responsibilities will include:

• Leading end-to-end UX research (user interviews, contextual observations, usability tests, and surveys) and centralizing insights in a structured research repository
• Facilitating framing, ideation, and co-design workshops with business stakeholders, IT squads, and end users
• Analyzing quantitative user behavior using web analytics (such as Matomo) and heatmaps to uncover pain points and drop-offs
• Building and refining personas, empathy maps, experience maps, and end-to-end user journeys
• Defining interaction models and measuring product success against clear usability benchmarks and KPIs
• Designing low-to-high fidelity wireframes, interactive prototypes, user flows, and site maps, presenting solutions persuasively to stakeholders
• Collaborating closely with UI designers to ensure strict alignment with the design system while actively contributing to the wider UX chapter

Requirements

Your Profile:

• 7+ years of experience applying Design Thinking methodologies in Agile environments, with mastery of both qualitative and quantitative research methods
• 3+ years of hands-on experience in interaction design and information architecture
• A formal qualification in UX (Master’s degree, recognized professional certification, or equivalent practical background)
• Advanced proficiency in Figma (wireframes, prototypes, user flows; experience with design systems is a plus), alongside tools like Miro, PowerPoint, and Matomo (experience with Condens is a strong plus)
• Proven track record in facilitating collaborative workshops with cross-functional and large stakeholder groups
• Strong communication, storytelling, and synthesis skills, combined with a pragmatic, autonomous, and resilient delivery mindset
• Good working proficiency in Dutch and/or French, alongside fluent English; German is an asset
• Valid authorization to work in Belgium (EU citizen or valid Belgian work/residence permit)
