Toast creates technology to help restaurants and local businesses succeed in a digital world, helping business owners operate, increase sales, engage customers, and keep employees happy.
A Bit About The Team
Every restaurant is different and faces its own unique challenges. Across global markets, these challenges vary significantly. The mission of the Europe team is to tackle these challenges head‑on by building purpose‑built products that meet the complex needs of the Europe customer base. This includes deepening the product experience with our existing European customers and also adapting our product for future market growth.
To meet these goals it involves building brand new products and features that integrate seamlessly into the existing Toast product suite. As a Principal Engineer on the team, you will set the technical direction for how we rapidly build iterative solutions within the existing Toast technology stack—all while maintaining excellent quality and architecting for long‑term scale.
As a Principal Engineer, you are expected to be closely aligned with engineering leaders across Toast. You will define and promote architectural best practices, champion new technologies and innovative thinking, and serve as a technical thought leader for the broader organization. You will be responsible for mentoring and upskilling the engineering teams around you.
If you're motivated by solving problems at the intersection of customer needs and technical challenges, and eager to leave a lasting mark on Toast’s future growth, this role offers a rare opportunity to do so.
