We're Hiring: Principal Consultant — AI & ML Solutions, 8–12 Years Experience ONLY
Aarvian is looking for a technically senior (not organisationally senior) Data Scientist who still lives in the code. This is a 60% hands-on / 40% technical leadership role — not a management position.
Please read before applying: This role requires 8 to 12 years of hands-on data science / ML engineering experience, with models personally built and deployed at production scale. If you have less than 8 years, or your experience is primarily people-management, dashboards, or stakeholder work without shipping production code — this is not the right fit, and your application won't be shortlisted. Please don't apply outside this range.
What You'll Do
Design & build production ML/AI models end-to-end — data pipelines, feature engineering, training, evaluation, serving, monitoring (not POCs, not notebooks)
Advanced ML: XGBoost, LightGBM, CatBoost, Random Forest — plus ensemble methods, causal models, or uplift modelling where needed
Build Agentic AI systems: multi-agent workflows, RAG pipelines,



LLM-powered business process automation (LangChain, LlamaIndex, simplAI, AutoGen)
Own retail use cases: demand forecasting, markdown/price optimisation, promotional uplift, inventory intelligence, customer segmentation
Act as the quality gate — review architectures, approve model designs, mentor by pairing (not lecturing)
Be the technical bridge between the delivery team and the AI/ML CoE owner
Must-Haves
8–12 years in data science / ML engineering, career spent close to the code
Models YOU personally built and deployed running at real production scale (not a 6-week pilot)
Solid hands-on with XGBoost/LightGBM/Random Forest — hyperparameter tuning, SHAP explainability, class imbalance
Expert Python (modular, testable, production-quality) and advanced SQL
Real Agentic AI exposure — a production or near-production multi-agent/RAG/LLM-orchestrated system (chatbot/FAQ-bot experience does not count)
