Data & Machine Learning Engineer (All genders)

About Us STARK is a new kind of defence technology company revolutionising the way autonomous systems are deployed across multiple domains. We design, develop, and manufacture high-performance unmanned systems that are software-defined, mass-scalable, and cost-effective — providing operators with a decisive edge in contested environments.

We are focused on delivering deployable, high-performance systems — not future promises. In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe, today.

About the team The Operations Excellence team sits within the COO organization and serves as a strategic partner to managers, team leads, and colleagues across Stark. By delivering data-driven insights, leading critical projects, and driving continuous process improvement, we help the organization operate more efficiently, scale effectively, and achieve its goals faster.

As an individual contributor, you will take end-to-end ownership of complex initiatives with significant business impact. Working closely with cross-functional stakeholders, you will have the opportunity to influence key decisions, shape core operating processes, and contribute directly to the success of one of Europe’s fastest-growing unicorns.

Your mission As Data & Machine Learning Engineer, you own the data infrastructure and ML model development for the OAA team's AI use cases. You build the pipelines that feed models with clean, reliable data from both operational systems and back-office sources, deploy models into production, and ensure they perform reliably — from yield prediction on the line to anomaly detection in financial data.

Responsibilities

Design and build data pipelines from operational (MES, ERP) and back-office sources feeding ML models

Develop ML models for production and back-office use cases — from experimentation through to production deployment

Deploy models into production: serving infrastructure, monitoring, drift detection, and retraining workflows

Work with the OAA Lead and stakeholders to scope and validate ML use cases — feasibility, data availability, ROI

Collaborate with the Automation Engineer to integrate model outputs into automated workflows

Maintain and improve deployed models as data distributions and operational conditions evolve

Document data pipelines, model architectures, feature definitions, and deployment configurations

Qualifications

4–7 years in data engineering or ML engineering

Demonstrated experience deploying ML models to production: not just research or notebook-level work

Python: core language for data engineering and ML development

SQL: data extraction, validation, and pipeline development

ML frameworks: scikit-learn, PyTorch, or equivalent

MLOps fundamentals: model versioning, serving, monitoring, retraining

MSc in Data Science, Computer Science, Statistics, or equivalent

Nice to have

Data pipeline tooling: Airflow, dbt, or equivalent

Cloud data platforms: AWS, GCP, or Azure

Experience with industrial, time-series, or back-office financial data
