You will become part of the AI and Automated Detection sub-division in Bratislava. Backed by a major AI investment program across the company, we build systems that defend against real-world cyber threats at scale, from automated threat detection processing terabytes of behavioral data, to multi-agent AI systems that help security analysts work faster, to SOAR platforms that automate incident response.

Our work spans distributed backend services, machine learning pipelines, LLM-powered agents, and production security tooling.

As a Python Software Engineer on the AI Security Platform, you build the backend systems that power AI-driven threat detection, automated incident response, and LLM-based security tooling. You will join one of three teams based on your interests and our needs, each tackling a different part of the security stack.

About the Role

• Design, build, and maintain distributed backend services and processing pipelines in Python.
• Develop asynchronous, event-driven systems and message-based integrations across services.
• Collaborate with software engineers, security researchers, and security operators across the division.
• Take ownership of services across their full lifecycle, from design and deployment to monitoring and troubleshooting.
• Write clean, maintainable, and production-ready code.
• Work with one of three focus areas, chosen based on your interests and team needs:

Detection Systems: automated threat detection pipelines, detection engine integrations, and high-volume data processing.

LiveAI: multi-agent AI systems, LLM-powered assistants, agent orchestration, and evaluation infrastructure.

SOAR Platform: microservice ecosystem for incident handling, automation workflows, and AI-powered Security Operations Center capabilities.
