Role: Senior AI/ML Engineer — Inventory Forecasting & Decision Systems
Hours: 9am - 6pm Eastern Time (Remote)
USD Salary: $20-$40/HR

We are seeking a highly skilled Senior AI/ML Engineer to drive the development of advanced inventory forecasting and decision systems. This is a senior, individual-contributor role with direct business impact, ideal for a self-directed engineer comfortable navigating ambiguity and building end-to-end ML solutions.

Responsibilities

• Build and improveinventory demand forecasting modelsusing ML and statistical methods.
• Own ML modelsend-to-end: data collection → feature engineering → training → deployment → monitoring → iteration.
• Developdecision systemsthat support inventory planning, pricing, and demand decisions.
• Build and maintaindata pipelinesand API integrations for external and internal data sources.
• Work withmessy real-world datato ensure model reliability through rigorous validation and testing.
• ImplementLLM/AI-agent workflowsto translate domain logic into automated processes.
• Operate independently in a small team, setting priorities, unblocking challenges, and communicating tradeoffs clearly.

Requirements

Must-Have Qualifications

• 5+ years of Python experience inproduction ML systems(beyond notebooks/research).
• Deep experience withstatistical modeling, including ensemble methods, kNN, calibration, cross-validation, and feature engineering.
• Expertise intime-series modeling & forecasting, including seasonality, trend decomposition, safety stock, and demand planning.
• Proven track record of shipping ML models thatdrive real business decisions(forecasting, pricing, demand planning).
• Strong intuition formessy, real-world data, including bias correction, stale signal handling, error cancellation, and distribution shifts.
• Experience withAPI integration and data pipeline architectureat scale.
• Hands-on experience withLLM/AI-agent workflows, including prompt engineering and evaluation frameworks.
• Proven ability tovalidate models rigorously: LOO, backtesting, production vs offline metric gaps.
• Self-directed, comfortable in afast-evolving, small team environment.

Nice-to-Have Qualifications

• Experience inAmazon marketplace, e-commerce, or retail analytics.
• Familiarity withsimilarity-based methods(kNN, embeddings, vector search).
• Experience maintaininglong-lived model systems(v1 → v30+ iteration cycles).
• Priorstartup or founder-adjacent experience.
