Job Description

Senior AI Data Scientist

MLabs

Role Description We are seeking a Senior AI Data Scientist to lead the design, evaluation, and evolution of the agentic systems behind our financial intelligence platform. This role sits at the intersection of LLMs, financial data, and decision systems. You will own the logic behind how our models reason over data, how agents coordinate and make decisions, and how they rigorously measure quality, correctness, and risk in production AI workflows. You’ll work closely with product, engineering, and research teams to move from experimentation to reliable, scalable AI systems that operate under real-world financial constraints. - System Design: Design and own single and multi-agent systems that reason, plan, and act over complex financial workflows. - Agent Logic: Define agent behavior, memory, and tool-use strategies with a strong emphasis on correctness and controllability. - Evaluation Frameworks: Develop and maintain LLM evaluation frameworks covering accuracy, faithfulness, latency, cost, regressions, and edge cases. - Production Implementation: Design structured prompting, schemas, and tool-calling strategies; build and operate MCP servers including schema design and safety boundaries. - Optimization: Analyze model behavior and failure modes to turn qualitative issues into measurable signals; optimize performance and cost across workflows. - Mentorship: Mentor engineers and data scientists, setting best practices for applied LLM and agentic systems. Qualifications - 6+ years in data science, applied ML, or AI-focused software roles, with at least 3+ years building production AI/ML systems (beyond the experimentation phase). - Deep hands-on experience with LLMs, agentic patterns, and tool-calling systems. - Strong Python skills and comfort working closely with production systems and APIs. - Proven experience with RAG pipelines, embeddings, and vector databases. - Strong intuition for model behavior, trade-offs, and failure analysis. Preferred Qualifications - Experience applying ML or statistical methods to financial data (crypto/DeFi is a major plus). - A track record of building reusable ML or data abstractions that improve team velocity. - A strong intuition for how model behavior shifts in production based on data, users, and constraints. Requirements - Recruiter / HR Call - 30min screen - Hiring Manager Interview - 30min technical screen - Technical Interview - 1-hour technical interview focused specifically on the "coding" elements eg Python and its libraries and machine learning - Technical Interview - 1-hour technical interview focused specifically on AI elements of the role (this will be more data science in nature) - Founder / CEO Interview - 30mins Benefits - Compensation & Equity: Competitive package aligned with growth and merit. Salary range: $130,000 – $150,000 (commensurate with experience). - Comprehensive Health: 100% employer-paid medical, dental, and vision options for you and your dependents, plus FSA/HSA options. - Time Off: 21 vacation days, 7 sick days, and 8 observed U.S. company holidays. - Family Support: Thoughtful parental leave policy. - Wellness: Access to OneMedical, Teladoc, Talkspace, and Employee Assistance Programs (EAP). - Career Growth: Personalized professional development in a rapidly expanding global company. - Commuter Benefits: Pre-tax commuter programs. Commitment to Equality and Accessibility At MLabs, we are committed to offer equal opportunities to all candidates. We ensure no discrimination, accessible job adverts, and providing information in accessible formats. Our goal is to foster a diverse, inclusive workplace with equal opportunities for all.

Full TimeRemoteTeam 51-200H1B No Sponsor

• Lead data exploration and analysis on large scale financial crime datasets — including sanctions, PEP (Politically Exposed Persons), and adverse media data — to uncover patterns, identify false positives/negatives, and drive feature improvements. • Develop and evaluate agents and rule-based models by running experiments, validating hypotheses, and fine-tuning thresholds to improve alert efficiency. • Build and deliver production-ready API integrations — coordinating with software engineers and product teams to ensure components are properly integrated, tested, and merged. • Conduct customer-focused data studies across multiple enterprise clients (e.g., financial institutions) to benchmark model performance, assess data quality, and propose data driven solutions to reduce investigation loads. • Prototype and iterate quickly — using PySpark, Jupyter notebooks, and Python to explore data, build reproducible pipelines, and generate insights that inform product decisions. • Investigate and resolve product issues in collaboration with engineering and product teams. • Contribute to R&D on emerging techniques — including graph-based approaches (GNNs, graph embeddings) for transaction monitoring, LLM-based feature exploration, and RAG-based models. • Communicate findings clearly through well-organized Jupyter notebooks, internal documentation, and stakeholder presentations, translating complex analytical results into actionable business insights.
