Carty will report to Michael Bell, Lucid's senior vice president of digital.
According to his LinkedIn profile, Carty joined Lucid in June and previously worked at his consulting firm, Carty Consulting. Before that, he held posts as director and senior director at Apple.
"Derrick's wealth of experience with systems architecture and his ability to lead teams that create customer-friendly, easy-to-use software interfaces is crucial as we continue to roll out new Lucid Air features via our over-the-air software updates," Bell said in the release.
Carty holds a bachelor's degree in computer science from Stanford University, Lucid said.
Lucid's Air sedan, which launched last year from the automaker's new factory in Arizona, has received strong praise from auto reviewers for its power, comfort, handling, range and efficiency.
However, there also have been complaints from reviewers and early buyers that the six-figure sedan's in-house software is slow, glitchy and incomplete.
"Lucid seems to have whiffed it when it comes to the Air's in-car tech and driver aids," Edmunds said in a review on its website. "Our test car was plagued by persistent Bluetooth connection errors on both iPhone and Android devices."
Edmunds also noted Lucid's delays incorporating Apple CarPlay and Android Auto software, which mirror smartphone applications such as music, navigation and podcasts onto a vehicle's infotainment screen.
Lucid, which has been regularly updating vehicle software through its over-the-air capability, has said CarPlay and Android Auto will be coming this year along with other improvements.
