The Role
You are a last-year Bachelor student or a 1st-year Master student in Computer Science or a related field?
Become part of our success story by applying to our SUMMER PRACTICE Program until the 30th of May 2026. This year, you will have the opportunity to continue the implementation of our summer practice projects and develop your skills by working 6 hours per day from 13th July until 4th September 2026.
All the summer practice will be done on-site (in Timisoara and Sibiu).
The Available Projects Are
Project 1: Business Formula Builder
You will build a visual interface for creating and editing business rules in a product used by both beginners and power users. The tool will offer two synchronized modes: a visual mode with blocks, forms, and guided flows, and a text mode with raw expressions. Smart assistance (searchable data and actions, short descriptions), instant feedback (inline error checks, basic type validation), and an AI chatbot will help users write, understand, and debug rules. A key challenge is to keep the interface simple for new users while remaining fast and powerful for experts, ensuring lossless conversion between visual and text modes and iterating quickly based on user feedback.
Technologies and frameworks: Vue, Vite, JavaScript, AI-assisted development (Claude Code)
Project 2: Configuration agents
You will design AI agents that understand business needs from natural language or existing configurations and turn them into actionable, system-ready setups. The project focuses on enabling users to interact with complex systems through intuitive, conversational interfaces while learning how to extract structured information from unstructured data and automate configuration processes using AI. You will work in an agile team, designing and prototyping agents for real-world scenarios, and iterating based on performance insights and user feedback.
Technologies and frameworks: Python, LangChain, LangGraph, LLM observability & MCP tools, modern AI/ML practices, prompt engineering
At Atoss, great talent knows no limits. We welcome professionals from all backgrounds and empower their growth through an inclusive, skill focused environment.
Join us and be part of a high-growth, future-focused company!
