Main Duties

As a Product Designer, you will have an exciting and central role developing, testing, and refining Halo’s digital platform. Presently, Halo is preparing for a 6-8 week Feasibility Study. The Study will engage with early stage users, gather rich health data, and stress-test assumptions and flows.

You will help to develop the platform that Study participants will use to enrol. You will design a landing page, onboarding system, and surrounding digital assets, working with a software developer to make your designs reality. You will translate our value proposition to prospective users into compelling visual communication. You will also design prototypes for planned features that embody how the platform will function, look, feel, and deliver value to users in the near future.

The role is ideal for a rigorous, ambitious, and thoughtful designer who enjoys pushing creative boundaries and wants to work out how to practically serve user needs. You will work closely with the Founder and CTO. While suitable as a short-term role for a set project, there is strong potential to join Halo for a longer duration as we rapidly grow over the coming months.

Key Responsibilities

● Own development of front-end UI and UX

● Create digital assets including website, illustration, animation, branding, presentation decks through a variety of methods (wireframes, rapid digital prototypes, and finished products)

● Design and refine a seamless onboarding journey, including the creation of engaging onboarding videos/visuals. We must ensure the transition from curious visitor to active participant is frictionless

● Develop dynamic and exciting ways to present health data to users, making it intuitive and empowering

● Express Halo’s value propositions through simple yet compelling visual communication

● Study competitors and differentiate Halo by creating a distinctive brand, aesthetic, and UI

● Publish assets, conduct quality checks, and troubleshoot problems where needed

● Justify design decisions to team, document thinking, and keep a file recording design iterations

● Curate presentation decks for public and private view
