AI / ML Engineer vs AI Research Scientist: Salary & Career Benchmarks in Poland

In Poland, AI Research Scientist roles typically command a higher median salary than AI / ML Engineer positions. According to our 2026 live benchmark data, a mid-level AI Research Scientist earns a median salary of PLN306K, whereas a AI / ML Engineer brings in roughly PLN287K (a gap of PLN19K at the median).

Seniority, tech stack, and location all move this gap. Senior practitioners in either discipline can exceed the upper range through specialist skills. See the skills premium section below for the specific certifications and tools that push offers to the top of the range.

While both positions are vital to a modern tech organisation, AI / ML Engineer and AI Research Scientist have fundamentally different daily workflows.

AI / ML Engineer focuses primarily on building and deploying machine learning models into production systems, spanning both model development and the engineering needed to serve them reliably. Day-to-day work revolves around training and fine-tuning models, building feature pipelines, containerising models for deployment, setting up monitoring for model drift, and collaborating with product teams on integration.

AI Research Scientist focuses on conducting original research into new model architectures, training techniques, or evaluation methods, and publishing or productionising findings. Their time is spent designing experiments, running large-scale training jobs, reading and writing research papers, and collaborating with engineering teams to translate findings into deployable systems.

Transitioning between these two paths is achievable but requires targeted upskilling.

Neither path requires starting from scratch. Professionals in both roles share underlying technology fluency; the gap is usually domain knowledge and specific tooling rather than core engineering fundamentals.

In Poland in 2026, both roles are seeing demand, but with different drivers.

AI / ML Engineer demand is extreme, particularly in Warsaw and Kraków product teams building AI-powered features, led by employers such as Microsoft and Nokia. AI Research Scientist demand is high, concentrated in Warsaw and Kraków product teams building AI-powered features, led by employers such as Samsung R&D Poland and Allegro.

Workspace flexibility significantly impacts total compensation value in Poland.

AI / ML Engineer roles score 68% on our remote-friendliness index (High). This is because model integration and evaluation work is tool-driven and remote-friendly, a norm that Poland's IT sector has broadly kept in place thanks to the widespread B2B (umowa B2B) contracting model, which gives both employers and specialists more flexibility than a standard umowa o pracę. Where in-office attendance is required, it is typically driven by product alignment sessions and cross-functional AI roadmap planning, which larger employers with a Kraków or Wrocław global capability centre are more likely than smaller Polish software houses to formalise into a fixed hybrid schedule.
