Toyota Motor North America Research & Development and an Engineering Culture
Read MoreWhat is an engineering culture?
At Toyota Motor North America Research & Development (R&D), it’s kaizen and collaboration, and the best dang engineers around creating products our customers love.
R&D engineers lead design and development for Camry, Tacoma, Tundra, Sequoia and Sienna. They also play a key role in development of Corolla, Corolla Cross, RAV4, Highlander, Grand Highlander, Lexus ES, Lexus NX and Lexus RX.
That’s not to mention advanced mobility projects, powertrain development, quality and materials, among plenty of other things.
Being an engineer at Toyota is a dream job for many, and that shows in the drive that R&D engineers bring to their work every day.
