Hybrid | Porto (Portugal) Full-time Cybersecurity & Defence

Who we are

Adyta is a Portuguese cybersecurity company based at UPTEC - University of Porto's Science and Technology Park. Our proximity to cutting-edge research isn't a coincidence - it's how we stay at the frontier of what's possible.

Our core mission is digital sovereignty. In a world where most communications infrastructure runs on foreign clouds and untrusted platforms, we build the alternative - technology that keeps sensitive conversations under the control of those who need it most.

We develop secure, high-assurance mobile and backend solutions for environments where reliability, privacy, and security are critical. Alongside it, we deliver cybersecurity services and contribute to European and national defence R&D consortia at the frontier of quantum-safe communications.

We are a small, technically ambitious team - and we are growing. The Android developer joining us will work directly on the product at the heart of what we do.
