Help businesses turn strategy into digital solutions: from AI-powered marketing to data-driven products and custom software. We combine business thinking with technical execution.

Every day, you might build an e-commerce platform using predictive analytics, design a high-impact digital campaign, or develop a data-driven product that drives measurable results.

Take the step towards your journey with us and join us as a Senior AI/ ML Developer in Lithuania, Hungary, Armenia or Poland!

Implement end-to-end AI features depending on the project, including, but not limited to: Computer Vision(detection/recognition pipelines, image preprocessing, evaluation, inference integration), NLP/Transformers (text classification, extraction, summarization, embeddings-based workflows), RAG / semantic search (ingestion -> chunking -> embeddings -> retrieval -> answer generation);

Improve retrieval quality using two-stage search (vector retrieval + reranking using cross-encoders/rerankers) when relevant to the project;

Work with vector search / vector databases in local and cloud setups: Self-hosted (Docker) and client environments, as well as cloud-managed search stacks (e.g., OpenSearch vector search, Azure AI Search hybrid/vector search);

Build and maintain Python backend APIs (FastAPI/Django) that serve AI pipelines reliably (auth integration, error handling, basic performance considerations);

Package solutions with Docker, help run deployments in cloud environments, and support debugging in dev/stage/prod;

Collaborate with software engineers, data engineers, and consultants to deliver working solutions under real project timelines.

6+ years of Python development (or equivalent strong practical experience) and ability
to ship working backend services;

Hands-on experience building at least two of: NLP/Transformer-based pipeline, RAG /
semantic search pipeline, Computer Vision pipeline;

Familiarity with embeddings + vector search concepts (indexes, filtering/metadata,
similarity search);

Comfort with Docker, Git, and Linux basics (running services locally, troubleshooting
dependencies);

Practical mindset: you can translate requirements into an implementable pipeline and
iterate quickly;

Upper-intermediate English;

Experience with IaaS cloud solutions (e.g., AWS, Azure, GCP), cross-encoders as
rerankers, OpenSearch vector search, Azure AI Search hybrid retrieval and semantic
reranking concepts, or basic ML serving/performance awareness would be a plus.
