UX UI Designer

Senior UX UI Designer

About the Role

NASMAK Technologies helps organisations innovate, automate and scale faster through AI-driven design, digital transformation and smart technology solutions. As our Senior UX UI Designer, you will own the user experience and interface design of the digital solutions we deliver for the organisations we work with.

You will take products from research and problem definition through to polished, tested interfaces ready for build. Your work will make AI-driven and automated tools clear, usable and trustworthy for the people who rely on them every day.

This is a full-time, hybrid role based in Sydney, New South Wales. It suits a senior designer who can shape both the experience strategy and the pixel-level detail.

Key Responsibilities

• Lead user research, including interviews, usability tests and journey mapping, to turn user needs into clear design problems and priorities.
• Design end-to-end user flows, information architecture and wireframes that make AI-driven and automated features easy to understand and use.
• Produce high-fidelity, accessible interface designs that meet WCAG 2.1 AA and give clients consistent, production-ready screens.
• Build interactive prototypes that test ideas with real users before development begins, reducing rework and late-stage changes.
• Create and maintain a design system of components, patterns and guidelines so every solution ships with a consistent look and behaviour.
• Design clear interfaces for AI outputs, automation steps and data, so users understand what the system is doing and can act with confidence.
• Prepare detailed design specifications and annotations so developers can build interfaces accurately on the first pass.
• Present design decisions to clients, linking each choice to user evidence and the outcomes the client wants.
• Define and track UX measures such as task success, completion time and satisfaction to show how design changes improve results.
• Review the design work of others and give clear, actionable feedback that raises the quality of every release.

What Success Looks Like

• Within 30 days, deliver a UX audit of one live solution with at least 10 prioritised usability improvements (suggested).
• Within 60 days, run usability testing with at least 8 users and turn the findings into an updated, tested prototype (suggested).
• Within 90 days, publish a design system of at least 25 documented, reusable components adopted on one active project (suggested).
• Every week, hand over development-ready designs for at least 2 features with complete specifications and no blocking open questions (suggested).

Requirements

• 5+ years of professional UX UI design experience, including at least 3 web or software products designed from research through to release.
• A portfolio showing end-to-end process: research, flows, wireframes, high-fidelity UI, prototypes and evidence of results.
• Hands-on experience planning and running user research and usability testing, and turning findings into design decisions.
• Experience building and maintaining a component-based design system used by designers and developers.
• Working knowledge of accessibility standards, including WCAG 2.1 AA, applied in shipped interfaces.
• Clear communication skills, with experience presenting and defending design decisions using user evidence.
• Australian citizenship or permanent residency, and the ability to work on a hybrid basis in Sydney, New South Wales.
• Tools you will use: a collaborative interface design and prototyping tool, a usability testing platform, a digital whiteboarding tool and a design handoff tool.

Nice to Have

• Experience designing interfaces for AI-powered products, such as chat assistants, recommendations or automated workflows.
• Experience designing data-heavy dashboards or analytics interfaces.
• A working understanding of HTML, CSS and front-end constraints.
• Experience in a consultancy or client-services setting, delivering design for several organisations.
• Experience with motion design or micro-interactions for user interfaces.

What We Offer

• Base salary of AUD 100,000 - 150,000 per year.
• Full-time employment.
• Hybrid work arrangement based in Sydney, New South Wales, Australia.
