"We are delighted to welcome Stephanie on-board as a new PETRONAS Trackside Fluid Engineer today," said D'Arrigo. "Since the start of the partnership with Mercedes-AMG PETRONAS, we have deployed engineers to operate in the PETRONAS Trackside Laboratory that travels with the team to every race throughout the season.
"These engineers represent the technical excellence of PETRONAS in Formula One and the company's commitment to building a pool of talent for the advancement of our fluid technology from track-to-road.
"PETRONAS employs the best and the brightest throughout the company and I believe that Stephanie's skillset, passion, determination and positive attitude will make her an incredible addition to our team."
Toto added: "PETRONAS has contributed greatly to the performance and the reliability that is at the very heart of the success we've enjoyed over the past five seasons. PETRONAS has continuously raised the bar throughout our decade-long partnership, providing us with the technology and the technical expertise to give us a competitive advantage.
"The PETRONAS Trackside Fluid Engineer programme has been part of our partnership from the very beginning; it's an important pillar in our hunt for performance and reliability. Having fluid engineers in the on-track laboratory gives us the opportunity to quickly analyse lubricants from the car and to respond to potential challenges in real-time.
"The programme has also become a great asset to find and develop talent in our highly competitive industry and I'm sure that Stephanie will further strengthen our team at the track. Welcome to the Mercedes-AMG PETRONAS Motorsport family, Stephanie!"
