About the project

Domain: Food Services / Transportation

Country: USA

Stack: Python, AWS
We are looking for Python Developer to work on our client's product—Zing.

Zing — the first network of mobile cafes leveraging data and advanced algorithms to optimize the suburban coffee experience. As more people work from home and the classic idea of suburban living evolves, Zing is determined to provide suburban commercial convenience that rivals anything in cities.

Zing creates magic by putting the right goods and experiences, at the right place and time, into customers’ lives.

The product consists of a mobile application for iOS and Android, written in React Native, and a backend in Python (with sqlalchemy for the database) and AWS (CDK, Lambda, DDB, RDS (MySQL), API Gateway, AppSync). The user sees coffee trucks on the map, can choose the one closest to him and place an order.

In the current production version, a third-party Flip disk system is used to display the menu, order, and payment.

When ordering, we simply open a web view with their website and allow the user to place an order there. Then we detect the order number by url and send it to the back, so it will be determined which order the user has made. Then the back pulls out the hooks and their API and sends us updates. However, the customer is dissatisfied with the integration with FlipDish, and right now they are developing their own functionality for menus, orders, and payments. Payment will be made via Stripe.

Determining the location of cars on the map is also implemented through a third-party platform, Onefleet. It is a separate mobile application running on the truck driver's phone, which reports his location to the OneFleet server. And from there, the Zing backend receives data via the API and sends updates to the Zing mobile application. In the long-term plans, this part will also be rewritten in-house.

Also, recently, a second on demand mode has been added, where you can call a truck directly to a given point, like an Uber.

Responsibilities:

• Implement the components that bind complex routing, supply-demand, product, on-demand algorithms, and mass scale user communication into a complete, mission-critical service.
• Define and implement effective cloud infrastructure scaling solutions based on best-in-class standard tools.
• Experiment with, test, develop, and scale new use cases for our product.
• Work closely with the engineering, operations and data teams to ensure we’re providing a best-in-class product to our customers.

Qualifications:

• 5+ years of backend programming experience.
• Solid algorithms and data structures knowledge.
• Fast learner – you can quickly master concepts, disciplines, and methods.
• Flexible team player with great communication skills.
• Pragmatic – when you hear about a difficult problem, you are able to simplify it so that you can easily solve it.
• Concise – you get stuff done, in a simple, elegant way.
• Obsessive about the customer experience and always looking for ways to improve it.
