We require someone with a strong conceptualisation ability, strong visual communication ability, drawing skills and sketchbook technique, who can design elegant solutions to complex workflows.

These initial visualisations will be put to the test as soon as they are finished; tested by customers and vendors alike, to establish where improvements / changes are required. Once testing is complete , it’s back to the sketch book to implement findings. This will continue until we are BOTH 100% happy with the product. Then it will be taken forward to the development stage!
