Die NodeZero™-Plattform befähigt Ihr Unternehmen, Ihre ausnutzbare Angriffsfläche kontinuierlich zu identifizieren, zu beheben und die Wirksamkeit der Maßnahmen zu verifizieren. Reduzieren Sie Ihr Sicherheitsrisiko, indem Sie Schwachstellen in Ihrem Netzwerk autonom finden, wissen, wie Sie sie priorisieren und beheben, und umgehend verifizieren, dass Ihre Maßnahmen wirken. NodeZero liefert produktionssichere, autonome Penetrationstests sowie weitere zentrale Assessments, die über Ihre größten internen, externen, Cloud- und Hybrid-Cloud-Umgebungen skalieren. Keine Agents erforderlich, kein Code zu schreiben, keine Berater zu beauftragen.

Beschreibung

• Build and evolve the agent harness and orchestration that turns an LLM into a reliable autonomous pentester, the loop that reasons over an application, forms attack hypotheses, acts, and verifies results. • Design the tools and tool-shaped feedback the agent uses to probe and exploit, and the structured-output and validation layers that keep it reliable (e.g., hook-enforced mandatory validation, schema-constrained outputs). • Translate the team's offensive expertise into repeatable agent capabilities — partnering directly with our attackers to encode how they think into something the agent can do consistently. • Own and grow our evaluation infrastructure: benchmark suites, a failure-mode taxonomy across the pipeline (discovery → hypothesis → exploitation → verification), and regression detection, so we actually know whether the agent is getting better. • Manage LLM inference in production: model selection, prompt and context engineering, and keeping cost and latency under control (we run on AWS Bedrock with centralized cost tracking). • Hold the line on production-safety and no-false-positives, every finding the agent reports has to be real and reproducible.

🎯 Anforderungen

• 5+ years building production software, with strong Python. • Hands-on experience building LLM-powered applications or agents, tool use / function calling, structured outputs, multi-step orchestration, and the glue that makes it all hold together. • A track record of making LLMs reliable in production, you've wrestled nondeterminism, designed around model limitations, and shipped something that worked when it mattered. • Real experience with evaluation: you've built or owned the harness that tells you whether a model or agent change is an improvement, not just a vibe. • Strong instincts for prompt and context engineering, and the judgment to keep the model's job small and well-scoped. • Solid software fundamentals — testing, observability, and the discipline to keep a complex agent debuggable. • Ownership mentality, comfortable owning a critical, fast-moving subsystem end to end.

🏖️ Vorteile
