Lucid Motors’ chief engineer Eric Bach is leaving the company after more than a decade, the company has announced.

Bach, who also served as Lucid Motors’ Senior Vice President of Product, has been with the company since 2015. He joined Lucid after spending three years as Tesla’s Director of Engineering, where he worked alongside Lucid Motors’ former CEO and CTO Peter Rawlinson. Bach spent more than 10 years at Volkswagen before Tesla.

TechCrunch has learned that Lucid’s VP of Engineering, James Hawkins, is also no longer with the company after spending 10 years there. Lucid Motors declined to specifically comment on his departure.

Bach’s and Hawkins’ departures are part of a wider shake-up announced Wednesday. Lucid Motors’ Vice President of Quality, Jeri Ford, is retiring as well. She will be replaced by Marnie Levergood, who is coming to the company from Scout Motors.

At the same time, Lucid Motors’ current Senior Vice President of Powertrain, Emad Dlala, is being elevated to oversee all of “Engineering and Digital.” Dlala was promoted once already earlier this year and has been with the company since 2015.

The executive shake-up comes as Lucid enters its ninth month without a permanent CEO after Peter Rawlinson suddenly resigned in February. Former chief operating officer Marc Winterhoff has been serving as CEO on an interim basis ever since.

The loss of Bach and Ford is the latest in a line of executive departures at Lucid Motors. The company’s head of investor relations, Senior Vice President of Operations, Managing Director for Europe, and the Vice Presidents of Software Quality and Marketing have all left within the last year.

The changes are happening at a critical moment in Lucid Motors’ history. The company finally launched its long-awaited luxury SUV, the Gravity, which the company expects will ultimately be more successful than the Air sedan, which it has struggled to sell.

Lucid Motors is also working on a midsized vehicle that will be priced closer to $50,000 in 2026, though it has said it likely needs to raise more money before that happens. On Wednesday, Lucid Motors announced that its majority owner — Saudi Arabia’s sovereign wealth fund — had boosted the cap of a loan agreement from $750 million to around $2 billion, which provides the company liquidity until 2027.

This story has been updated with more information about departures and the amended loan agreement announced Wednesday.
