About The Role
We are seeking an experienced Senior ML to join our team and engage in a diverse range of client projects within the defence, national security, and commercial sectors. At BMT we accelerate our business through informed and targeted application of ML and LLMs.
As a Senior ML Engineer, you will be responsible for:
* Design, build, and deployment of machine‑learning systems, applying robust software engineering practices and an in‑depth understanding of model behaviour, performance, and limitations.
* Select, prepare, and pipeline data for model training and inference. Implements, trains, evaluates, and optimises machine‑learning models, continually improving them through iterative experimentation and additional data.
* Create scalable and automated ML pipelines, including feature extraction, model training, validation, packaging, deployment, and monitoring.
* Design and implement dashboards, diagnostics, and evaluation tooling to ensure transparency, performance tracking, and operational reliability across the ML lifecycle.
* Within defined delivery goals, refine prototype models into production‑ready components, contributing to development, optimisation, demonstration, and integration activities.
* Apply standardized engineering and evaluation methods, producing clear technical documentation and communicating design choices, performance outcomes, and limitations.
* Contribute to internal knowledge bases and participate in professional ML engineering communities.
* Ensure responsible handling of data throughout the ML lifecycle, including secure storage, access control, data lineage, versioning, and quality checks.
* Evaluate data integrity and suitability for ML workflows, and advise on transformations, feature representation, and schemas needed for efficient training and inference.
* Implement metadata standards, reproducible data pipelines, and automated validation procedures to maintain trustworthy data assets.
* Design, develop, test, document, and maintain moderately complex machine‑learning services, APIs, and supporting software.
* Write well‑structured, maintainable code using agreed standards and tools.
* Apply engineering‑focused data modelling and system design techniques to create, modify, or maintain ML‑relevant data structures, feature stores, and associated components.
About You
As the Senior ML Engineer, you will have skills in:
* Solution Engineering: Capability to design and implement end‑to‑end ML pipelines (data ingestion → feature engineering → training → evaluation → deployment).
* Model Development: Ability to select, train, and tune models (classical ML and deep learning) using frameworks such as PyTorch, TensorFlow, or scikit‑learn.
* MLOps & Productionisation: Experience containerising and deploying models (e.g., Docker), implementing CI/CD, monitoring, drift detection, and automated retraining on Azure/AWS/GCP.
* DataOps & Quality: Demonstrated capability to work with data engineers for high‑quality datasets, versioning, lineage, and governance.
* Collaboration & Mentoring: Pairing with data scientists and software engineers, reviewing code, sharing best practices, coaching juniors.
* Research & Reuse: Evaluating emerging techniques, creating reusable components/templates.
* Software Foundations: Strong engineering skills in Python (typing, testing, packaging), experience with Git and code review workflows.
* ML Expertise: Hands‑on experience building and shipping ML models; solid understanding of metrics, validation strategies, and responsible AI considerations.
* MLOps Engineering: Experience with cloud ML platforms (Azure Machine Learning or AWS/GCP equivalents), CI/CD tooling, containerisation using Docker, model monitoring.
* MLOps Frameworks: Proficiency with MLflow, Airflow, Kubeflow, SageMaker, or Azure ML.
