Senior Mechanical Engineer

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.

Toast’s hardware team is responsible for designing and developing top-tier hardware devices. We operate as a streamlined team that emphasizes the essential aspects of pos (point of sale), payment devices, and accessories, while crafting our devices to provide optimal hardware solutions for our clientele. Through our close interactions with customers, we have identified the crucial design features that render our devices genuinely restaurant-grade.

Our focus is on the long‑term dependability of our devices, ensuring that our customers can rely on their toast hardware without concern, allowing them to be prepared for another bustling day.

As a Senior Mechanical Engineer, your responsibilities will include the design, analysis, and prototyping of new products; testing and validation of products ready for launch; and providing support to Sustaining Engineering throughout the lifecycle of Toast hardware products. You will operate within a product‑focused development environment and collaborate with both Toast's internal cross‑functional teams and external suppliers to design and deliver products through to production.

Given the highly competitive nature of our industry, you will be required to innovate and create iconic devices for the rapidly evolving POS hardware sector. A robust mechanical design background, meticulous attention to detail, comprehension of critical design processes, and familiarity with fast‑paced development cycles are essential. You will be expected to collaborate closely with cross‑functional teams in operations, product development, industrial design, program management, project management, and hardware to define and deliver exceptional products.

We empower small teams to achieve significant results in a dynamic work environment.

• Design and create the mechanical elements of POS devices and their subsystems. drawing on knowledge and experience from the development of payment devices.
• Create part designs and mechanical systems, guiding them from initial concept through to production with full ownership per product engineering development team.
• Formulate test plans and product specification documents for both internal evaluations and external clients.
• Work in collaboration with a cross‑functional team to produce devices of exceptional quality.
• Gain an understanding of the restaurant environment and design products that can withstand it.
• Identify the root causes of various issues (design, manufacturability, production) to enhance designs and ensure successful mass production of products.
• Design with considerations for functionality, reliability, human factors, manufacturability, and aesthetic requirements.
• Address reliability failure and quality concerns related to products currently in use by Toast customers in the field.
• Leverage cutting edge AI tools to enhance your development workflow, improve velocity, and help pioneer new approaches to building - contributing to a culture of innovation and productivity across the team.
