Tech Lead [Senior]

🏛 The DEUS Initiative

We're a team of curious minds who believe technology should serve people. Our mission is to unlock the potential of AI for humanity through solutions that are not just innovative, but also ethical and impactful. We're driven by a desire to simply make things better.

Our name is inspired by deus ex machina, not because we think we’re gods, but because we design AI that steps in to support, solve, and serve.

DEUS also stands for what we do best:

Data | Engineering | User Experience | Strategy

With offices in Amsterdam, Porto, and A Coruña, we collaborate on international projects that challenge us to think deeply, build with care, and design for human good.
