Principal Applied Scientist

• Top-tier medical dental and vision coverage
• 401(k)

You will own the deterministic enforcement layer that guarantees compliance before AI messages are sent driving accuracy cost and latency tradeoffs. You will work as the senior individual contributor on this layer collaborating directly with the founder and backend engineers to define technical direction. Hybrid (3 days onsite) in the New York City area.

• Own the deterministic detection and enforcement layer end to end: rule system retrieval matching logic and production runtime
• Build the evaluation harness and labeled-data flywheel to demonstrate and improve accuracy
• Measure and optimize precision recall cost and latency and balance tradeoffs between them
• Define architecture direction for the deterministic layer alongside model and retrieval components
• Translate plain-language policy and regulation into deterministic rules and own the reasoning behind each decision
• Adapt rules to customer-specific policies including per-tenant configuration
• Run tight error analysis on missed violations and false alarms to improve trust and performance

• 8 years in applied ML NLP or high-accuracy detection systems with shipped production work
• Hands-on experience in information retrieval entity recognition pattern and rule design and rigorous evaluation
• Proven judgment as a senior individual contributor who sets technical direction
• Strong instincts for when deterministic rules outperform models and how to push precision and recall
• Bias for shipping and for measuring outcomes of what you ship

• Experience in compliance regtech or other regulated domains
• Building high-precision/high-recall detection or classification systems (fraud security content moderation etc.)
• Experience adapting a rule system to many customers (per-tenant policy/configuration)
• Experience combining deterministic and model-based components in production
• Public research open source contributions or technical writing
