Senior Machine Learning Engineer
We are seeking a highly skilled Senior Machine Learning Engineer with deep expertise in NLP, large language models, and model deployment to build and operationalize the core ML components that power Loopio’s next‑generation search, summarization, and answer generation capabilities.
Base pay range : CA$141,500 – CA$188,700 per year.
What You’ll Be Doing
Advanced Modeling & Applied Science
- Build and productionize large language model (LLM) and NLP models across retrieval, summarization, classification, and generative tasks by developing optimized embedding pipelines, prompt strategies, and fine‑tuning methods while translating prototypes into robust production components.
- Improve model accuracy, relevance, and robustness through structured evaluation frameworks, systematic error analysis, and iterative experimentation that ensures predictable behavior over time.
System Architecture & Engineering
Design and implement scalable ML services and inference pipelines in Python using modern ML frameworks, incorporating efficient serving strategies such as batching, caching, streaming, and performance‑tuned deployment patterns that meet latency and throughput requirements.Integrate models with retrieval systems, feature stores, and knowledge sources while applying strong engineering discipline in automated testing, observability, logging, and operational readiness.Contribute to core architectural decisions that balance modeling complexity with performance, maintainability, and long‑term extensibility.Delivery, Collaboration & Leadership
Translate complex NLP and LLM product requirements into structured engineering plans with clear milestones while collaborating closely with Product, Engineering, and Applied Science partners.Participate in technical design reviews and champion improvements in ML engineering practices, including deployment standards, model QA, code quality, and operational excellence while providing informal mentorship on modern NLP techniques.Demonstrate strong ownership and attention to detail by delivering high‑quality work in a fast‑moving environment focused on reliability and meaningful outcomes.What You’ll Bring to the Team
Proven Expertise in Machine Learning, Language Models, and NLP
4+ years applying ML in production with practical depth in NLP, LLM workflows, embeddings, or retrieval‑augmented systems.Hands‑on and deep experience with transformer models, embedding‑based methods, and retrieval‑augmented techniques, prompt‑structured or fine‑tuned LLMs for reasoning and generation tasks.Ability to turn prototypes into stable engineering solutions that perform consistently in production environments.System Design, Scalability, and Software Engineering Rigor
Strong proficiency in Python, modern ML frameworks such as PyTorch or TensorFlow, and API or microservice development.Experience building scalable and reliable ML services with attention to latency, observability, testing, deployment patterns, and runtime durability.Ability to design robust agentic components including control flow, state management, and integrations with retrieval and knowledge systems.Business and Product Acumen
Ability to frame technical decisions in terms of customer impact, product value, and measurable improvements to workflow efficiency or answer quality.Strong collaboration skills with cross‑functional partners to align priorities and drive clear, grounded execution.Comfort operating with ownership and urgency in a fast‑moving environment focused on delivering meaningful outcomes.Where You’ll Work
