Data & Machine Learning Engineer

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, the company is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe, today.

The Operations Excellence team sits within the COO organization and serves as a strategic partner to managers, team leads, and colleagues across the company. 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.

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.

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
