Requirements:

• Demonstrable UX design experience on complex B2B, operational, analytical, security, defence, public-safety, transport or similarly demanding software products.
• Experience designing for data-heavy applications, including search, filtering, prioritisation, investigation and exception handling.
• Strong experience translating complex processes, data and stakeholder requirements into clear user journeys and task flows.
• Good working knowledge of Figma, Miro, Overflow, or similar tools to create wireframes, prototypes, user flows, process maps, and product journeys, and to collaborate effectively with UI designers and engineers.
• Excellent information architecture, interaction design and workflow-design skills.
• Ability to define UX requirements clearly enough for UI designers and engineers to execute with confidence.
• Ability to make sound UX decisions from available evidence when regular direct user research is constrained.
• Strong communication and facilitation skills, with the ability to align product, technical and operational stakeholders around a shared user experience.

• Familiarity with secure systems, permissions, audit trails and sensitive-data considerations is desirable.

Responsibilities:

• Lead UX thinking for surveillance, security and operational software products.
• Break down complex user tasks into clear journeys, decision points, workflow steps and interaction models.
• Define information architecture, navigation, hierarchy and content structure for data-rich applications.
• Map current and future-state workflows, service journeys and product concepts using Overflow.
• Create wireframes and interactive prototypes in Figma to test and communicate user flows.
• Define the functional and interaction requirements that UI designers use to create polished interfaces.
• Work with product managers, engineers and operational subject-matter experts to clarify user needs and product requirements.
• Design effective workflows for alerts, investigations, incidents, triage, filtering, timelines, playback and case management.
