ML Researcher (NXJ-129)
We’re looking for an experienced ML researcher to own the full lifecycle of machine learning projects – from problem formulation and research through production deployment and monitoring. You will design, build, and deploy ML models, mainly on tabular data, with full ownership over their production performance and business impact.
Responsibilities
Develop, train, and evaluate ML models, with a focus on tabular, predictive, and ranking models
Work with data across the full funnel to support performance and optimization use cases
Contribute directly to production-focused modeling, ensuring models are practical, scalable, and reliable in real-world use
Requirements
Bachelor’s degree in Machine Learning, Statistics, Computer Science, or a related field
3+ years of experience developing ML models for tabular data, with strong understanding of underlying methodologies
Proven experience owning ML projects end-to-end — from research to production
Proven ability to extract predictive signal from complex, messy real-world data at scale
Experience training models on Big Data and optimizing for inference latency
Hands-on experience with cloud-based ML platforms and MLOps practices (experiment tracking, model versioning, CI/CD, deployment pipelines)
Strong Python skills and solid experience with tabular ML libraries (scikit-learn, PyTorch, pandas, polars, etc.)
Solid understanding of experimental design, causality, and robust model validation techniques
Experience working closely with data engineering pipelines
Will be a plus
Advanced degree in Machine Learning, Statistics, Computer Science, or a related field
Hands-on experience with causal inference, uplift modeling, A/B testing, and MAB
Familiarity with modern AI APIs (OpenAI, Anthropic, Google), RAG pipelines, and/or agentic AI systems
Experience deploying ML models to production: packaging, building inference APIs, and latency optimization
Familiarity with drift detection, data quality checks, and model performance monitoring
Experience with Docker and model-serving frameworks (FastAPI, Flask, TorchServe, BentoML)
What we offer
Competitive salary and benefits package
Medical insurance
Top equipment kit
Full Remote
Collaborative and innovative work environment
Career growth and development opportunities
A chance to work with a talented and driven team of professional
