About Ditto

At Ditto, we're redefining digital trust. Our unified identity platform helps banks, financial institutions, governments and other regulated organisations verify identities, prevent fraud and deliver secure digital experiences through identity verification, authentication, passwordless access and mobile threat defence.

We're a integral team with a startup mindset, led by CEO Gonzalo Alonso, on a mission to make digital trust simple, secure and accessible.

The Role

Ditto Protect is our mobile application security (RASP) platform — the runtime layer that keeps high-assurance apps safe while they run, on devices we do not control. We're hiring a Product Security Engineer to own the runtime defences that keep every Ditto Protect app trustworthy. This is a hands-on engineering role first and foremost: you'll write production code, contribute to the delivery pipeline, and ship the features that close gaps in Ditto Protect, working at high velocity with AI as your primary development accelerator.





You'll build our in-house shields and hardening tooling on top of a licensed RASP core — defeating rooting and jailbreaking, hooking and instrumentation, emulators, tampering and repackaging, malware, and network interception including MITM, SSL-pinning bypass, and malicious VPN/proxy. You'll own the applied cryptography beneath secure local storage and app/device attestation, as well as the iOS symbol-obfuscation and binary-hardening tooling that closes native reverse-engineering gaps across Swift, C, C++ and Objective-C.

The product spans both sides of the wire. You'll also build and operate Ditto Protect's Python backend — the services and APIs that ingest threat telemetry from protected apps, drive the operator and companion console, manage configuration and policy, and forward events to SIEM — turning on-device signals into operational visibility. This is a role for an engineer comfortable moving between the mobile client and the server.
