Job Description
Data Scientist
Vouch Recruitment
• Build and iterate on LLM & AI-powered product features • Design, prototype, and ship features that use LLMs (e.g., content generation, summarization, classification, semantic search, assistants, recommendations). • Work with engineers to integrate LLMs into the product via APIs or internal services (RAG, tools/functions calling, workflows, pipelines). • Define evaluation strategies for LLM features (e.g., human-in-the-loop evaluation, rubrics, prompt experiments, offline/online metrics). • Continuously refine prompts, data pipelines, and system design based on user behavior, quality metrics, and product goals. • Own product analytics for data- & AI-powered features • Partner with product managers and designers to define success metrics (e.g., adoption, engagement, conversion, retention, quality, time-to-value). • Instrument new features: define events, ensure proper logging, and validate that data is correct and trustworthy. • Analyze funnels, cohorts, user journeys, and experiment results to understand drivers of behavior and outcomes. • Translate insights into clear recommendations that influence roadmaps, prioritization, and feature iteration. • Work with real-world transactional data (SQL & NoSQL) Explore, clean, and transform data from transactional (OLTP), analytical (OLAP), and event-based systems. • Work across SQL (e.g., Postgres, Snowflake) and NoSQL (e.g., Redis, document/Key-Value stores). • Design data assets and features that are usable by both analytics workflows and LLM/ML systems. • Define and track data quality metrics (completeness, consistency, timeliness, drift, schema changes). • Build checks, monitors, and alerts to detect data issues that can affect analytics or AI/LLM performance. • Work with data and engineering teams to diagnose root causes and drive changes that improve data quality over time. • Use core ML concepts (feature design, model evaluation, bias/variance, generalization) to reason about LLM and non-LLM approaches. • When appropriate, build and evaluate lighter-weight or traditional models (e.g., scoring, ranking, classification) to complement or replace LLM solutions.
Job Requirements
- A track record of high ownership: taking responsibility for problems end-to-end, improving systems rather than just describing them, and pushing initiatives across product, engineering, and data.
- A genuine love for messy, real-world data, and the curiosity to dig into anomalies until you understand what's really happening.
- Hands-on experience with real-world transactional data in production environments, including messy, incomplete, or biased data.
- Demonstrated experience improving data quality in production environments.
- Demonstrated experience shipping LLM-based product features, such as: Using hosted LLM APIs or in-house models Designing prompts and workflows Evaluating and iterating on LLM behavior using real user data.
- Experience in product analytics, including: Defining and tracking product KPIs and feature-level metrics Building and interpreting funnels, cohorts, and retention/engagement analyses Influencing product decisions and roadmaps with data-driven insights.
- Experience measuring and improving data quality, and working with engineering to fix upstream issues.
- Strong communication skills: ability to work cross-functionally and explain technical decisions and trade-offs to non-technical partners.
- Strong SQL skills: complex joins, window functions, CTEs, and performance-aware querying.
- Solid Python skills for data and AI work (e.g., pandas, NumPy, scikit-learn; OpenAI, Anthropic, and Gemini LLM libraries/frameworks).
- Formal education in machine learning concepts, such as: Supervised/unsupervised learning Model selection and regularization Evaluation methodologies (train/validation/test splits, cross-validation, experiment design)
Benefits
- Competitive compensation and equity packages
- Health, dental, and vision insurance
- Parental leave
- Flexible vacation time
