Senior AI Engineer (LLM) @ Tidio Poland

How this role works:

You will start by building the system as part of our team, working in a focused, greenfield setup. After a few months of introduction to the project, you will seamlessly continue working on the same product directly with the client, becoming part of the client’s team responsible for its long-term development and scaling. There is no handover phase and no context switching - you stay with the same codebase, product, and technical challenges, while gaining long-term ownership and impact.

Biggest challenges in this role:

• Greenfield project built from scratch
• High-scale, user-facing systems with strict performance and reliability requirements
• Designing systems meant for long-term ownership, not short-term delivery
• Balancing model quality, latency, and cost in production LLM systems

What you’ll learn:

• How to build LLM-powered products from scratch and take them to production
• Proven approaches to running LLMs in production at scale
• How to design, evaluate, and evolve NLP systems used by real users
• Best practices for production ML and AI system architecture
  

What you’ll get to try and experiment with:

• End-to-end ownership of LLM-based systems
• Optimizing retrieval models, RAG pipelines, and inference workflows
• Experimenting with different LLMs, prompting strategies, and system designs
• Solving performance and reliability challenges under heavy traffic

We want to offer you:

• Work with an experienced team that continually shares knowledge and is not afraid of testing new solutions
• Flexible hours
• Individual work tools - Macbook Pro, Dell screen, JBL headphones? You can tailor the equipment to your needs
• Sport & wellness benefit (Kafeteria MyBenefit)
• Private medical care
• A comprehensive benefits package after transitioning to our partner, including employee benefits, training opportunities, and occasional bonuses
