At Q-tech, we are working with an international technology company with more than 30 years of experience developing critical software solutions for the financial sector. Their specialty is creating the software layer that allows banks to communicate with advanced physical devices such as cash machines, banknote recyclers, smart safes, and fraud detection equipment.

Their technology is present in Europe, the United States, Canada, Africa, and Asia, making their platform a global benchmark within a market that continues to grow, especially in North America, where cash usage remains very high.

The company has a key development hub in Valladolid, where the team responsible for its most strategic platform is located. In recent years, they have experienced sustained growth, growing from 10 to nearly 30 professionals, and their goal is to continue expanding the team to around 50 people.

We are looking for a Backend Engineer who wants to join the team responsible for a platform used by financial entities all over the world. This is a key role within the Valladolid technology hub, where the next generation of a product is being developed—a product that manages banking devices in real time and is now being transformed to scale, modernize, and reach the public cloud.

You will be part of the team driving the backend of the main platform, working on both new functionalities and architectural evolution. Your impact will be direct on a critical product used by banks in different countries.

Your daily tasks will include:

Develop and maintain backend services in Python.

Collaborate in the design of a scalable architecture prepared for the public cloud.

Work with real-time systems and communications between software and physical devices.

Integrate with low-level layers using industrial protocols (you will be trained if you do not have experience).

Contribute to continuous improvement, refactoring, and modernization of key components.

Cooperate with international teams (Europe and USA) and with the frontend team in Flutter.

Help reduce knowledge silos and provide new ideas to improve the product.
