Mid/Senior .NET Backend Engineer [working in Portugal's time zone]

We are one of the fastest-growing technology and innovation groups in Latin America, and since 2021, we’ve been operating in Portugal.

We are currently collaborating with a leading global e-commerce group, present in Asia, Europe and in the Americas. In this context, we are looking for someone with energy, a sense of responsibility, and motivation to take on the role of Mid/Senior .NET Backend Engineer , in one of the strategic initiatives we are leading with this client.

We work across various domains, including Unified Commerce, Application Development, AI (of course), and Cybersecurity, with over 1,700 professionals distributed across 12 companies in Brazil, Portugal, and the United Kingdom – through projects, managed services, squads, and staff augmentation.

Portugal serves as our service hub for the Northern Hemisphere. From here, our team supports clients in Portugal, the European Union, the United Kingdom, and the United States.

In Europe, in addition to the FCamara brand as a technology service provider, we are also the main investor and shareholder of Beta-i, a leading name in the field of open and collaborative innovation.

At FCamara, members of our consulting and service teams – proudly known as Orange Blood – find a space to grow and develop their skills. We work on challenging initiatives with real impact, creating the conditions for a true professional leap.

Whether joining with prior experience or through our Orange Juice programme, we are proud that many of our talents have gone on to become entrepreneurs or have progressed into leadership roles such as CTOs, IT Directors, Innovation Leads, or other senior positions in companies around the world.

"Those who join FCamara usually leave much better than when they arrived." – said by former Orange Bloods, not by us.
