Software Engineer, Full Stack

Description

Its software lets security teams check how attackers might fool staff into getting inside systems.

The platform runs authorized simulations by phone, SMS, and deepfake.

The team is extending it to cover what follows a click, a shared code, or granted access: account and session takeover, and how security controls react.

The company runs its own fine-tuned model, voice synthesis, and self-hosted phone infrastructure. Most engineering uses TypeScript, Rust, and AWS.

The founder led BlackRock's red team earlier and worked in offensive cyber operations at MITRE.
