I'm seeking an experienced product designer/engineer to create a cohesive family of watering nozzles and hose attachments. Key requirements: - Handheld watering nozzles with adjustable spray patterns and ergonomic design. - Hose attachments that complement the nozzles. - Durable and high-quality construction, preferably using metal. Ideal skills and experience: - Background in designing ergonomic tools - Experience with metal products - Strong understanding of irrigation and watering systems - Ability to create cohesive product lines - Emphasis on exterior look, with modern touches, rather than internal functions. (we have engineers who are great with functionality) Please provide samples of previous similar work and a rough timeline.
