Join Noma Security and help shape the future of AI security in a fast-paced, high-impact environment.
Noma is building the first comprehensive AI Security and Governance Platform, helping organizations adopt AI and LLMs with confidence and control. As AI becomes core to modern enterprises, we provide seamless visibility and protection across the entire AI lifecycle. Our team works at the intersection of AI, security, and cloud, shaping a new category in a rapidly evolving market. At Noma, you’ll have the opportunity to make a meaningful impact while working with exceptional people on technology that truly matters.
We’re looking for a Senior Data Scientist to be a core driver in how our product empowers security teams. You will be expected to deeply understand customer needs and translate them directly into product features that deliver real value. You'll own key parts of our frontend stack, drive key architectural decisions, and turn complex security data into clear, actionable business insights.
In this role, you will design, build, and productionize advanced models that help organizations secure AI systems across data, models, and runtime usage. You’ll work closely with Product, Engineering, and Security teams to turn complex, real-world security problems into scalable, high-impact AI solutions.
This is a high-impact, hands-on role with true ownership, where your work directly shapes the intelligence powering a category-defining AI Security platform.
🛠️ What You’ll Do:
• Own End-to-End Model Development (Research → Production)
• Take full ownership of the model lifecycle: problem definition, research, prototyping, training, evaluation, deployment, and ongoing optimization.
• Design and build scalable ML / AI solutions to detect, analyze, and mitigate AI-related security risks.
• Ensure models are robust, explainable, and production-ready in real-world enterprise environments.
• Partner Deeply with Product & Engineering
• Collaborate closely with Product Managers to translate customer pain points and security requirements into clear modeling objectives.
• Work hands-on with engineering to integrate models into production systems and data pipelines.
• Balance research depth with pragmatic execution and business impact.
• Build AI Security Intelligence
• Develop capabilities across areas such as AI behavior analysis, anomaly detection, model governance, data risk detection, and usage observability.
• Work with structured and unstructured data, including logs, prompts, model outputs, and metadata.
• Continuously iterate on models based on usage patterns, feedback, and emerging threat vectors.
• Lead Research POCs & Innovation
• Stay at the forefront of LLMs, applied ML, and AI security techniques and bring new ideas into the product.
✅ What You Bring:
• 5+ years of experience in Data Science or Applied ML roles.
• 3+ years of backend development experience, working with production systems.
• Strong hands-on experience with language models / LLMs and modern ML techniques.
• Bachelor’s degree in Computer Science (or equivalent practical experience).
• Proven experience owning end-to-end research POCs, from ideation to real-world impact.
• Strong understanding of product and business value, with a bias toward lean, effective solutions.
• Deep understanding of language models
🎯 Nice to Haves
• Experience in AI security, application security, or threat detection.
• Background in LLM workflows, RAG pipelines, prompt analysis, or multi-model systems.
• Experience building internal platforms or developer-facing ML tooling.
• Previous experience in leadership roles such as Tech Lead or Team Lead.
• Startup experience, especially in early or growth-stage companies.
