Responsibilities:

• Own the ML lifecycle: take models from problem framing through training, deployment and monitoring
• Frame problems: turn business goals into ML tasks and metrics. Use plain code where a model isn’t needed
• Build models: classical ML, time series and NLP, plus LLM and RAG features where they fit
• Evaluate rigorously: sound validation, the right metrics, and evals that gate every release
• Ship and run models: deploy with Docker and CI/CD on cloud ML platforms, and monitor drift and cost
• Deliver with AI: use AI coding agents throughout, and validate their output strictly
• Collaborate: review code and experiments, mentor others and explain results to stakeholders

Requirements:

• ML experience: 5+ years, with models shipped to production
• Python: pandas, scikit-learn, and PyTorch or TensorFlow
• ML fundamentals: validation, overfitting, feature selection, imbalanced data
• Data: strong SQL; Spark for large datasets
• MLOps: Docker, CI/CD, model serving and monitoring
• Cloud ML: SageMaker, Azure ML or Vertex AI
• LLMs: has shipped LLM or RAG features and written the evals for them
• AI-assisted development: uses an AI coding assistant daily and keeps its context (codebase, data schemas, standards) current
• Communication: fluent English; explains model trade-offs to non-technical people

Desirable:

• Anomaly detection and forecasting
• Recommender systems or ranking
• Fine-tuning (LoRA/PEFT)
• LangGraph or MCP
• MLflow, Airflow or Kubeflow
• Terraform and Kubernetes
• LLM cost control: model routing, caching, token budgets
• AWS Certified Machine Learning Engineer – Associate or Claude Certified Developer (Anthropic)

What’s in it for you?

• Strong community: Work alongside top professionals in a friendly, open-door environment
• Growth focus: Take on large-scale projects with a global impact and expand your expertise
• Tailored learning: Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company-paid certifications
