IriusRisk is the world's leading automated threat modeling tool (*our grandma says so). Born out of a desire to advance threat modeling as an activity and ensure that software is secure from the design stage. IriusRisk helps the largest banks and technology providers build their software. Yep, that's right, the team builds the tools that build the world's software.

A scale-up with large enterprise clients that retains a fast-paced, agile, get-things-done, start-up mentality. A place where everyone's ideas are welcomed, valued, and challenged, meaning the entire team has the opportunity to change how software is built securely at the very largest scale. We also love a meme.

You'll get hands-on with the latest LLMs, experiment with innovative prompt strategies, and shape how agent-based architectures deliver real-world value in the security space.
