Senior ml engineer

Overview   Torinit Technologies Inc. is a Canadian-based digital consulting company. At Torinit, we don't just serve our clients; we work with them to create transformative digital journeys by leveraging the latest technologies and world-class best practices. Our goal is to create an environment of continuous learning and success for our team and our clients.    We are a fast-growing team of passionate problem-solvers and life-long learners who aren't afraid of tackling complex problems. We've got a talented team of skilled, friendly, and driven individuals spanning the globe (primarily based in Canada and India), now we're looking to add more world-class talent to our team.    Role Overview   We are seeking a Machine Learning Engineer  with 3–5 years of experience to design, build, deploy, and optimize ML/AI solutions across a range of business problems. The ideal candidate understands the full ML lifecycle —from data preprocessing and experimentation to deployment, monitoring, and continuous improvement.  The role requires strong engineering fundamentals , modeling expertise , and practical knowledge of MLOps , along with the ability to convert business use cases into scalable ML pipelines.  Key Responsibilities   1. Model Development & Experimentation   Build, train, and evaluate machine learning models (classification, regression, clustering, NLP, deep learning).  Develop custom models or adapt pre-trained models (transfer learning).  Conduct feature engineering, feature selection, and data transformation.  Perform hyperparameter tuning using tools like Optuna, Ray Tune, or built-in frameworks.  Evaluate model performance using appropriate metrics (AUC, F1, MAE, BLEU, WER, etc.).  2. Data Engineering & Processing   Work with structured and unstructured data (text, images, audio, logs, documents).  Build data pipelines using Python, SQL, Spark, Airflow, or similar.  Apply data quality checks, deduplication, anomaly detection, and data validation (Great Expectations, pydantic).  3. ML Deployment & MLOps   Deploy models as APIs using Fast API, Flask, Node, or cloud-native tools.  Implement CI/CD pipelines for ML (Git Hub Actions, Git Lab, Jenkins).  Use containerization & orchestration (Docker, Kubernetes).  Manage models using MLflow, Vertex AI, Sage Maker, Azure ML, or Databricks.  Implement automated retraining, model versioning, rollback, and monitoring.  Handle inference optimizations (quantization, batching, caching).  4. LLM & Gen AI (Preferred but not mandatory)   Work with foundation models like GPT, LLa MA, Claude, Mistral, etc.  Build RAG pipelines with vector databases (Qdrant, Pinecone, FAISS, Elasticsearch).  Prompt engineering and evaluation.  Optimize embeddings, context windows, and chunking strategies.  Integrate LLMs into production APIs and workflows.  5. Cloud & Infrastructure   Experience with at least one cloud provider (AWS, Azure, GCP).  Use managed ML services like:  AWS: Sage Maker, Lambda, Textract, Comprehend  Azure: AI Foundry, Functions, Search  GCP: Vertex AI, Cloud Run  Manage GPU/CPU compute workloads efficiently.  6. Software Engineering Best Practices   Write clean, modular, well-tested Python code.  Maintain repositories adhering to branching, versioning, and code review standards.  Use design patterns for scalable ML pipelines.  Build internal tools for automation, testing, and monitoring.  7. Cross-functional Collaboration   Work closely with product managers, data engineers, backend engineers, and business analysts.  Translate business problems into ML solutions with measurable ROI.  Document technical designs, APIs, models, architecture diagrams.  8. Monitoring, Observability & Optimization   Implement model monitoring for data drift, concept drift, performance degradation.  Evaluate model reliability, bias, fairness.  Implement logging & metrics (Prometheus, Grafana, ELK).  Continuously improve model performance and resource usage.  Required Skills & Experience   Technical Skills   Strong Python skills  (Num Py, Pandas, Scikit-learn, Py Torch or Tensor Flow).  Proficiency in ML algorithms , data structures, and ML system design.  Experience with deep learning , especially CNN/RNN/Transformers.  Knowledge of LLMs , embeddings, tokenizer concepts (preferred).  Strong understanding of vector databases  (Qdrant, FAISS, Pinecone).  Hands-on experience with REST APIs , microservices, and cloud-native deployment.  Familiarity with SQL , No SQL, and data warehouses (Snowflake/Big Query/Redshift).  MLOps & Infrastructure   Docker, Kubernetes, Terraform (good to have).  MLflow or equivalent for experiment tracking.  CI/CD automation experience.  GPU optimization and parallel processing experience.  Soft Skills   Strong problem-solving abilities.  Excellent communication for explaining technical concepts to non-tech stakeholders.  Ownership mindset and ability to work independently.  Ability to work in a fast-paced, iterative, Po C-driven environment.  Curiosity to continuously learn new technologies.  Preferred Qualifications   Bachelor’s or Master’s degree in Computer Science, Engineering, Mathematics, or equivalent experience.  Experience building ML products end-to-end.  Experience in domains like Fin Tech, Healthcare, Retail, Manufacturing, or Real Estate is a plus.  Contributions to open-source ML frameworks are a bonus.  Torinit’s Ethos   Our guiding principles are the cornerstone of our success, shaping a dynamic environment where innovation, quality, and continuous growth are not just valued; they're celebrated.
