The Machine Learning Engineer reports to the Group Service Support Specialist and takes ownership of the key function of Data Science and ML engineering,This role primary function is to turn raw fleet telemetry, scheduling inputs and operational data into decisions, predictions, and insight that improve the performance of mining operations.

This is the foundational analytical hire - responsible for exploring data, defining problems, collaborating with domain experts, and building models that inform the product roadmap across predictive maintenance, anomaly detection, operator behaviour, and dispatch optimisation.

Typical features to commercialise are multivariate anomaly detection, failure prediction, estimate remaining life prediction, schedule optimisation, OR(Vehicle routing problem), Computer vision solutions.

The role is expected to be able to take ownership of the entire chain of commercialised ML features in the product, including formulating problems, identifying and implementing data infrastructure requirements and implementing ML operational models.

Job Overview

Data exploration and problem formulation
Conduct structured data audits on incoming data streams, assessing signal quality, completeness, historical depth, sampling frequency, and suitability for each modelling use case
Translate ambiguous business questions into scoped problem statements defining target variable, features, data requirements, modelling approach, and success criteria
Distinguish between problems requiring machine learning, statistical analysis, or rules-based logic and recommend the right approach for each.

Maintain a prioritised problem inventory with documented assessments of data readiness, tractability, effort, and business value.

Identify data inventory deficiencies and formulate plans to solve and or retrieve.

Data Architecture and Engineering
Design and implement ingestion pipelines
Build and maintain ETL pipelines transforming raw sensor streams into clean, structured, model-ready feature sets
Design data warehousing and architecture that is fit for purpose.

Monitor pipeline health, data freshness, and schema drift as the fleet and product evolve.

Vender selection and justification with respect to the expected outputs and associated costsModel Development and ValidationMaintain a structured model registry tracking all experiments, versions, hyperparameters, and evaluation metrics to ensure full reproducibility of any model at any point in time.

Implement monitoring frameworks for deployed models that track prediction quality, input data distributions, and output stability over time.

Define and document retraining protocols for each deployed model specifying trigger conditions, data requirements, and the validation criteria a model must pass before replacing the current version.

Collaborate with engineering to package validated models into production-ready artefacts with clearly documented input formats, output schemas, and failure handling expectationsEvaluate and recommend appropriate deployment patterns for each model based on latency, reliability, and operational requirements.ML Ops and production readinessValidated and commercially viable models to be developed into production ready solutions for the product.

Track all experiments, model versions, hyperparameters, and evaluation metrics in a structured model registry ensuring full reproducibility
Implement monitoring frameworks for deployed models tracking prediction quality, input distributions, and output drift over time
Establish automated alerting for model degradation and define retraining triggers based on performance thresholds
Design retraining protocols specifying trigger conditions, training data windows, and validation gates a model must pass before replacing the current version
Collaborate with engineering to package validated models into production-ready artefacts with clear input formats, output schemas, and failure handling specifications
Evaluate and recommend appropriate serving infrastructure for each model - batch, near-real-time API, or edge deployment - based on operational requirements Communication Insights and stakeholder engagement
Present model findings and analytical results to non-technical leadership in plain language with honest confidence estimates and clear business implications.

Communicate proactively when data assumptions underpinning a modelling initiative are not met, recommending corrective action rather than proceeding on a weak foundation.

Document all analytical decisions, model assumptions, and data limitations in a form accessible to engineering, product, and future data science hires. Skills, Knowledge & Attributes
