• Design and implement end-to-end AI systems and services that integrate with backend applications.
• Build and refine retrieval-augmented generation pipelines, agents, and evaluation workflows.
• Assess models, tools, and frameworks for practical use.
• Improve the scalability, reliability, and cost efficiency of deployed solutions.
• Own assigned features and contribute to technical and architectural decisions with senior engineers.

Requirements

• At least three years of software engineering experience, including one to two years focused on AI or machine learning systems.
• Experience deploying AI solutions in production and a solid grasp of LLM systems, retrieval, agents, fine-tuning fundamentals, and evaluation.
• Practical Python experience with tools such as PyTorch or Hugging Face, plus data engineering experience with NLP, computer vision, or tabular data.
• Understanding of embeddings, vector databases, retrieval systems, REST or GraphQL APIs, and cloud infrastructure on AWS, GCP, or Azure.
• Good system design skills and the ability to turn requirements into working solutions in a fast-moving team.

Nice to have

• Node.js and TypeScript experience; the backend stack uses these technologies.
• Familiarity with multi-agent systems and MLOps, or experience optimizing a deployed AI solution for performance, latency, or cost.
• Startup experience.

Benefits and work setup

• Onsite, hybrid, or remote work in Croatia, with flexible hours.
• Compensation based on experience and market conditions, plus workstation, home office, and annual education budgets.
• Additional offerings include paid sick leave, an annual health check, office meals and refreshments, and support for parking or public transport.
