Take your career to new heights with Loopio!

We are seeking a highly skilled Senior Machine Learning Engineer with deep expertise in NLP large language models and model deployment. This role focuses on building and operationalizing the core ML components that power our next generation search summarization and answer generation capabilities. You will work closely with Applied Scientists Product and Engineering to bring advanced models from prototype to reliable scalable production systems.

Note: This is an existing vacancy on the team

What Youll Be Doing:

Advanced Modeling & Applied Science

• Build and productionize LLM and NLP models across retrieval summarization classification and generative tasks by developing optimized embedding pipelines prompt strategies and fine-tuning methods while translating experimental prototypes into robust components that consistently perform under production conditions.

• Improve model accuracy relevance and robustness through structured evaluation frameworks systematic error analysis and iterative experimentation that ensures predictable behaviour 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 reliability 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 to support durable maintainable ML systems.

• 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 to align expectations remove constraints and deliver measurable customer impact.

• 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 and scalable model serving.

• Demonstrate strong ownership and attention to detail by driving high-quality delivery in a fast-moving environment focused on reliability clarity and meaningful outcomes.

What Youll 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
