Category: Product Design / User Experience

Date Posted: 2026-08-14

Experience Level: 5-10 Years

🚀 Role Summary

• Lead User Experience (UX) strategy and execution for complex surveillance, security, and operational decision-support software products.

• Define intricate user journeys, robust workflow logic, and intuitive information architecture for data-rich applications.

• Create detailed wireframes and interactive prototypes using industry-standard tools to validate and communicate user flows and interaction models.

• Collaborate closely with product managers, engineers, and subject-matter experts to translate user needs and complex requirements into actionable design specifications.

• Focus on enhancing user understanding, investigation capabilities, and actionable insights within a sophisticated operational environment.

📝 Enhancement Note: This role is positioned as a senior UX Designer due to the emphasis on leading UX thinking, defining complex workflows, and making sound design decisions with limited direct user research. The requirement for experience in "similarly demanding software products" suggests a need for a designer accustomed to high-stakes, mission-critical applications.

📈 Primary Responsibilities

• Spearhead UX design initiatives for advanced maritime surveillance, security, and operational software.

• Deconstruct complex user tasks into clear, actionable user journeys, decision points, workflow steps, and interaction models.

• Establish comprehensive information architecture, navigation structures, visual hierarchy, and content organization for data-intensive applications.

• Develop and document current and future-state workflows, service journeys, and product concepts, utilizing tools like Overflow for visualization.

• Design and produce wireframes and interactive prototypes in Figma to rigorously test and effectively communicate user flows and interaction paradigms.

• Clearly articulate UX requirements, interaction rules, and acceptance criteria to guide UI designers and engineers in creating coherent and effective product experiences.

• Foster collaboration with product managers, engineers, and operational subject-matter experts to refine user needs and product specifications.

• Design optimized workflows for critical operational functions including alert management, incident investigation, triage, data filtering, timeline analysis, playback, and case management.

• Proactively identify and mitigate design friction, ambiguity, unnecessary steps, and excessive cognitive load within operational tasks.

• Maintain meticulous documentation of UX decisions, interaction rules, and acceptance criteria to ensure consistency in implementation and facilitate iterative improvements.

📝 Enhancement Note: The responsibilities highlight a strategic role involving not just design execution but also the definition of "product concepts" and "future-state workflows." The emphasis on documenting "acceptance criteria" suggests a strong need for the UX designer to bridge the gap between design intent and engineering implementation, ensuring fidelity in execution.

🎓 Skills & Qualifications

Education: Bachelor's degree in Human-Computer Interaction (HCI), Design, Computer Science, or a related field, or equivalent practical experience.

Experience: Minimum of 5-10 years of demonstrable UX design experience, with a significant portion focused on complex B2B, operational, analytical, security, defense, public-safety, transport, or similarly demanding software products.

Required Skills:
