About The Position

This is a high-impact individual contributor role focused on building Fetcherr’s product, not pure research. The Data Science Engineer joins a team of Data Science Engineers and contributes code, owning well-scoped modeling problems end to end—from exploring market data and designing features to validating models and deploying them to production. The work helps Fetcherr’s pricing, inventory, and network optimization engines make better decisions in real time.

The role sits at the intersection of applied AI and production software, collaborating with data scientists, ML and data engineers, and product teams. It involves developing and evaluating models using large-scale, high-velocity market data, and ensuring deployed models are reliable, observable, cost-efficient, and explainable to commercial teams and customers. The engineer also contributes to the technical direction of the modeling stack as Fetcherr expands to new customers, verticals, and product lines.

Requirements

• At least 5 years of full-time experience as a Data Scientist, Applied Scientist, ML Engineer, or in a similar role building models that run in production. Lab, proof-of-concept, prototype, academic, and part-time experience does not count toward this requirement.
• Strong Python programming skills and production-grade coding practices, including testing, code review, and version control.
• Solid foundation in statistics, machine learning, and time-series forecasting, with sound judgment on model validation and experiment design.
• Strong SQL skills and experience working with large relational and non-relational datasets.
• Experience and comfort with AI-assisted software development, along with the ability to write and reason about code independently.
• Experience with cloud platforms and modern data warehouse and lakehouse technologies; GCP and BigQuery are preferred.
• Familiarity with orchestration tools such as Airflow or Dagster, and with CI/CD practices for ML and data pipelines.
• Strong analytical mindset and a pragmatic, get-it-done approach.
• Excellent collaboration and communication skills, with comfort working cross-functionally with engineering and product teams.

Nice To Haves

• Experience with dynamic pricing, revenue management, or optimization problems.
• Experience in travel, e-commerce, logistics, or other real-time decisioning domains.
• Exposure to MLOps practices such as model registries, monitoring, and automated retraining.
• Experience with real-time OLAP engines such as ClickHouse.
• Experience in a Software-as-a-Service environment.

Responsibilities

• Develop, validate, and iterate on demand forecasting, pricing, and optimization models using large-scale, high-velocity market data.
• Explore and analyze data from diverse internal and external sources to uncover signals, define features, and identify opportunities to improve model accuracy and business impact.
• Design and run offline experiments, backtests, and online evaluations to measure model performance and profit uplift.
• Write production-grade Python code and work with ML and data engineers to productionize models, ensuring they are reliable, observable, and cost-efficient.
• Monitor deployed models for drift, accuracy, and data quality issues, and troubleshoot and fix problems quickly.
• Build models whose logic and outcomes can be explained to commercial teams and customers, consistent with Fetcherr’s glass-box principles.
• Partner with product and commercial stakeholders to translate business problems into clear modeling approaches and communicate results.
• Contribute to the technical direction of the modeling stack as Fetcherr scales across new customers, verticals, and product lines.
