This Singapore engineer helped build Apple's products for 22 years. Now he's redrawing his own blueprint

Singaporean engineer Mark Sin spent 22 years shaping Apple's hardware while rallying the Singaporean community in the San Francisco Bay Area as president of SingaporeConnect. Now, he is stepping away to explore a new chapter – and how he can give back to Singapore in new ways.
For 22 years, Singaporean engineer Mark Sin helped shape Apple products used by millions worldwide – from the Apple Watch to the Mac Pro, the company's high-performance desktop computer.
The 49-year-old has spent the past two decades working behind the scenes in hardware design and systems integration, steadily rising through the ranks to become a key figure in the company's engineering endeavours.
It's the kind of career so many in the tech industry aspire to have – packed full of achievements and milestones, and positioned at the forefront of global innovation.
Then, in December 2025, with the job title "engineering architect" at Apple Inc, he walked away from one of the world's most coveted engineering jobs.
He said the decision was not impulsive. He had weighed his options over time, revisiting the question of whether to stay at Apple – and in the United States – almost every year. Each time, he had decided to stay.
