Engineers Quit High-Paying Jobs to Open Coffee Shop

Most people don’t quit well-paid engineering jobs to sell coffee on the street. But that’s exactly what Matthew and Mia did. Tired of lab coats and clean rooms, the former engineer duo walked away from stable corporate roles to chase a shared dream—opening their own coffee shop. It wasn’t an overnight decision, nor an easy one. Their journey began not with a sleek café, but with a cart on the sidewalk, a coffee machine, and a lot of doubt.

Yes, two former engineers really did leave high-paying tech jobs to start a coffee shop—with zero experience in hospitality. They began by selling coffee from a street cart on New Year’s Eve, testing recipes, refining techniques, and building a customer base from scratch.

The Engineer Couple Behind the Coffee Shop

Matthew worked as a mechanical and air-conditioning engineer after earning his master’s degree, while Mia, trained in chemistry, served as a production engineer. Both spent long hours in labs and cleanrooms—and both were passionate about self-roasted coffee. They often joked about opening a coffee shop, but like many people, never took the leap. That changed when Matthew had to resign to care for his sick mother, giving the couple the time and push they needed to finally pursue their dream.

From Cart to Café: A Step-by-Step Journey

Their first step wasn’t a storefront—it was a street cart. On New Year’s Eve, they pushed a coffee machine onto Zhongzheng Road in Hsinchu City and started selling coffee. “At first, it felt really embarrassing,” Matthew said. “But once we made that move, the dream didn’t feel so far away anymore.” The response was unexpectedly positive, confirming their belief that they could turn this passion into a real business.

Encouraged by the support, they began looking for a permanent location, hiring part-time staff, and slowly building toward their own café. That dream became reality with the opening of Maya Bakery & Café, located in Hsinchu’s Zhongzheng Road area.

Science Meets Coffee: Applying Engineering Skills

Much like in their previous jobs, Matthew and Mia applied technical thinking to coffee. Matthew, with his mechanical background, focused on dialing in precise temperature control during brewing. Mia, with her chemical engineering expertise, managed coffee-to-water ratios and recipe formulation. Every day, they brewed, tasted, adjusted, and refined their blends until they achieved the flavor profile they wanted.

Overcoming Doubt and Early Struggles

The path wasn’t smooth. Both sets of parents opposed the career shift, worried about stability. The couple faced additional challenges when they first opened the shop—some days saw zero customers. “There was a lot of external pressure, and we felt uncertain too,” Matthew admitted. “But we believed in what we were doing, and kept improving.” Gradually, customer retention improved, regulars returned, and the café found its footing.

Frequently Asked Questions

Why did Matthew and Mia quit their engineering jobs?

Matthew left his job to care for his sick mother, which gave the couple the opportunity to rethink their careers. Both had long dreamed of opening a coffee shop but lacked the time or courage until then. Mia also wanted to leave the corporate environment behind for a more creative and hands-on pursuit.

How did they start their coffee business?

They began with a street cart on New Year’s Eve, serving coffee to pedestrians. This allowed them to test their recipes, build confidence, and gauge public response without the overhead of a storefront. The positive feedback encouraged them to take further steps toward opening a real shop.

What roles did their engineering backgrounds play in running a coffee shop?

Matthew used his mechanical engineering skills to manage temperature settings and equipment, ensuring optimal brewing conditions. Mia applied her chemical engineering knowledge to perfect coffee ratios and ensure consistency in flavor. Their technical approach helped refine their coffee offerings scientifically.

Did they face any challenges when opening the café?

Yes. They dealt with opposition from family who thought they were making an unstable career choice. Early days in the café also saw slow business, with some days having no customers at all. They persevered through self-doubt and gradually built a loyal customer base.

What’s the story behind their coffee shop’s location?

Their café, Maya Bakery & Café, is located on Zhongzheng Road in Hsinchu City—a spot they initially tested with their street cart. The location became their first permanent storefront after they gained enough experience and customer interest from their roadside sales.
