  • Iterate designs based on feedback and technical constraints

Qualifications

  • Degree (or equivalent experience) in UX, Human Factors, Design, Computer Science, or related discipline
  • Proven experience in UI/UX design for software, systems, or technical products
  • Experience working with engineering or development teams
  • Ability to deliver design outputs in short, delivery-focused engagements

Essential skills

  • Wireframing and interface layout design
  • Usability principles and best practice application

Desired skills

  • Strong experience simplifying complex workflows into usable interfaces
  • Experience working within constrained or legacy environments
  • Experience collaborating with engineering teams to deliver implementable designs
  • Experience in defence, government, or regulated environments (desirable)

What do I need before I apply

  • A portfolio demonstrating practical UI/UX delivery (wireframes, flows, layouts)
