If you're passionate about building real-world AI systems that solve complex cybersecurity challenges, and want to work with a world-class team, this is your moment.
Key Responsibilities

  • Architect and implement end-to-end machine learning pipelines tailored for cybersecurity use cases (EDR/XDR/NDR).
  • Develop models that detect, prevent, and remediate sophisticated cyber threats using deep learning, GenAI, and NLP techniques.
  • Design and run large-scale experiments to evaluate the effectiveness of AI-driven threat detection strategies.
  • Apply modern ML frameworks (e.g., PyTorch, TensorFlow, Hugging Face Transformers) to analyze structured and unstructured security data.
  • Work with product, engineering, and threat research teams to translate domain insights into production-grade models.
  • Lead technical research and stay current with academic and industry advancements in AI for cybersecurity.
  • Contribute to the core ML platform design, including data pipelines, model training/inference infrastructure, and observability.
What We're Looking For
  • 7+ years of experience in machine learning, with at least 3 years focused on applied AI in cybersecurity or infrastructure.
  • Deep expertise in ML model development, especially in anomaly detection, time-series analysis, and NLP.
  • Experience working with cybersecurity telemetry (e.g., endpoint, network, or cloud data) is highly preferred.
  • Strong understanding of EDR/XDR/NDR technologies, networking protocols, and cloud environments.
  • Proficiency in Python and ML frameworks such as PyTorch, TensorFlow, scikit-learn, and Hugging Face Transformers.
  • Demonstrated ability to take ML models from prototype to production at scale.
  • Familiarity with MLOps practices and cloud-native environments (e.g., AWS, GCP, or Azure).
  • MS or PhD in Computer Science, Electrical Engineering, Applied Mathematics, or a related field.
Why Join Kipling Secure
  • Be part of a founding team building a category-defining product at the forefront of AI and cybersecurity.
  • Collaborate with accomplished leaders from the world’s top tech companies and research institutions.
  • Influence the technical direction and vision of a rapidly growing startup.
