About the Opportunity
We are building a new category of enterprise AI software focused on helping organizations safely deploy, govern, and operate AI systems in production. Our founding team brings experience building and scaling cloud infrastructure, cybersecurity, and enterprise software products used by some of the world’s largest organizations.
We’re looking for a hands-on Cofounding Data Scientist who wants to help build both the product and the company from the ground up.
What You’ll Do
- Build and curate datasets that become a strategic asset for the company.
- Fine-tune, evaluate, and optimize open-source foundation models for enterprise use cases.
- Design ML pipelines for risk detection, classification, anomaly detection, and behavioral analysis.
- Develop data engineering workflows for data collection, processing, labeling, and evaluation.
- Work closely with product and engineering to productionize ML capabilities.
- Define model quality metrics, evaluation frameworks, and benchmarking methodologies.
- Engage with design partners and customers to understand real-world problems and translate them into product capabilities.
- Help shape product direction, technical architecture, hiring, and company strategy as a founding team member.
Requirements
- Strong background in Data Science, Machine Learning, or Applied AI.
- Experience building and managing datasets and data pipelines.
- Hands-on experience fine-tuning and evaluating open-source models (Llama, Mistral, Gemma, Qwen, DeepSeek, or similar).
- Functional data engineering experience, including ETL and large-scale data processing.
- Experience with AWS and/or GCP cloud services.
- Strong Python skills and familiarity with modern AI/ML frameworks.
- Excellent written and verbal communication skills.
- Comfortable operating in a fast-moving startup environment with significant ownership and ambiguity.
Nice to Have
- Experience leading enterprise software, machine learning, or data science projects.
- Experience building production AI systems used by enterprise customers.
- Familiarity with LLMs, AI agents, RAG architectures, model evaluation, or AI governance.
- Experience in cybersecurity, cloud infrastructure, or enterprise SaaS.
- Prior startup, founder, or early-stage experience.
Who You Are
- Builder first, researcher second.
- Curious, pragmatic, and customer-focused.
- Comfortable wearing multiple hats and learning new domains quickly.
- Excited by the opportunity to create a company and category from the earliest stages.
- Motivated by ownership, impact, and long-term value creation.
Why Join
- Meaningful founder-level equity.
- Direct influence on product, technology, and company strategy.
- Opportunity to help define an emerging category in enterprise AI.
- Work alongside experienced leaders who have built and scaled enterprise software, cloud, and security platforms.
- Build something from day one rather than joining after the foundation has already been laid.
If you’re interested in building a company at the intersection of AI, enterprise infrastructure, and security, we’d love to talk.
