Job description

STX Next is a software house working hands-on with the latest AI technologies. We build solutions based on LLMs, RAG systems and AI automation, integrating them into our clients’ environments in a thoughtful, stable, and production-ready way. We are looking for an AI Engineer who feels confident working end-to-end: designing architecture, implementing solutions, and bringing them all the way to deployment. You’ll join an experienced engineering team that supports each other while maintaining a high level of autonomy and ownership.

Responsibilities

• Building and deploying RAG systems (various domains: e-commerce, finance, operations).

• Working with LLMs: finetuning, prompt engineering, architecture design, integrations.

• Creating and expanding APIs, pipelines, automations, and surrounding AI processes.

• Using n8n for automations where it makes sense.

• Designing solutions end-to-end: from presales (together with the team), through architecture, to deployment.

• Participating in projects involving vision, classical ML, or predictive maintenance when required.

• 10–20% research — depending on the project. Delivery comes first.

Requirements

• Production-level Python (PEP8, clean architecture, maintainable code).

• At least one commercially deployed AI/ML project (no course projects).

• Strong knowledge of: - LLMs- RAG- HuggingFace / PyTorch (or TensorFlow)

• Ability to build end-to-end applications: API, pipeline, monitoring, validation.

• Basic MLOps knowledge (Docker, logging, basic automation, clean environments).

• Proficiency in at least one cloud (AWS/GCP/Azure) and willingness to learn others when needed.

• Ability to communicate with clients at a normal, technical, no-nonsense level.
  Nice to have:

• Experience with vision computing or classical ML.

• Knowledge of vector DBs (Weaviate, Qdrant, Pinecone).

• MLflow / Airflow / DVC / wandb.

• Any level of CI/CD experience.
  This role is for you if:

• You can solve problems independently.

• You don't need a full specification to move forward.

• You read documentation and follow good practices.

• You enjoy projects that end with deployment, not “experiments”.

• You prioritize solid engineering over hype.
