Senior Applied Scientist

The Research & Intelligence team builds the machine learning and semantic intelligence capabilities at the core of Carbon Arc. Our work spans graph-based entity resolution, temporal and causal modeling, data valuation systems, and retrieval-augmented applications that operate over massive, heterogeneous data assets.

We are seeking a Senior Applied Scientist to lead and expand key research directions at the intersection of knowledge graphs, retrieval, and predictive analytics. In this role, you will own end-to-end ML systems—from research ideation and prototyping through production deployment—while inventing new ways to make data interoperable, valuable, and actionable at scale.

This is a high-trust, high-impact role for someone who thrives on experimentation, rapid iteration, and building systems that have not existed before.

What You'll Do

• Design and deploy machine learning pipelines for entity resolution, semantic linking, and data quality scoring across structured and unstructured data sources
• Build downstream NLP and retrieval applications, including retrieval-augmented generation (RAG) and graph-based RAG over an enterprise knowledge graph
• Apply graph learning, vector retrieval, and embedding-based similarity to unify analytics across text, metadata, and operational signals
• Extend and operationalize temporal and causal modeling capabilities, representing events, sequences, and hierarchies within the knowledge graph
• Apply temporal and causal models to forecasting, anomaly detection, and predictive analytics use cases
• Maintain and evolve Carbon Arc's knowledge graph by enriching ontologies, improving linking logic, and optimizing downstream reasoning
• Establish rigorous standards for model evaluation, monitoring, and lifecycle management in dynamic data environments
• Collaborate closely with engineering teams on model design, API integration, and distributed inference workflows
• Mentor scientists and engineers on experimental design, responsible AI practices, and scalable deployment
• Contribute to intellectual property development, including internal frameworks, patents, and publications advancing data economics

What You'll Bring

• 5+ years of experience delivering machine learning, AI, or statistical modeling systems in production environments
• MS or PhD in Computer Science, Statistics, or a related technical discipline
• Deep proficiency in Python and modern ML frameworks such as PyTorch or TensorFlow
• Experience working with distributed data and compute technologies (e.g., Spark, Ray, Kubernetes)
• Strong background in unstructured data modeling, including embeddings, information retrieval, and LLM-based systems
• Proven ability to take research prototypes and scale them into reliable, production-grade services
• Clear, precise technical communication skills that support effective cross-functional collaboration

Nice to Have

• Experience designing and optimizing RAG or Graph-RAG architectures, including LLM evaluation and IR-driven optimization
• Hands-on expertise with vector databases, graph databases, graph algorithms, and ontology-driven modeling
• Experience with time-series forecasting, Bayesian inference, or causal modeling applied to economic, behavioral, or operational prediction
• Exposure to optimization, analytics, or modeling in data valuation or pricing systems

What We Offer

• Fully paid healthcare benefits (Medical, Dental, Vision)
• Remote work options
• 401(k) plan with employer contributions
• Paid time off
• Generous parental and family leave policies
• Challenging problems to tackle with a supportive, entrepreneurially driven team
• A strong work culture centered on integrity, excellence, truth, trust, and transparency

Location

Carbon Arc is headquartered in New York City and operates as a remote-first company. Team members are expected to travel for in-person onsite gatherings at least one week per quarter to collaborate, plan, and connect as a team.
