About the Company

• Enterprise AI development platform that emerged from a hidden activity in 2025 thanks to $50+ million in funding.
• Main purpose: The platform allows companies to deploy customized AI solutions (such as document automation, operational analytics, and AI agents) in days, not months.
• Enterprise segment and deep integrations with enterprise business processes.
• Key features: The platform is model-agnostic, meaning users can use their own AI models, and it guarantees data privacy without training third-party models on customer data.

Candidate requirements:

• Education and fundamental knowledge: Higher education in Computer Science (Bachelor's or Master's) with a focus on algorithms, data structures, and discrete mathematics. A deep understanding of the fundamentals is required: asymptotic analysis (Big O, Theta, Omega), dynamic programming, graphs (BFS/DFS, shortest paths), trees (binary, AVL, B-trees), hash tables, queues, stacks and heaps. Candidates without a formal CS education will not be considered.
• Engineering mindset: Proven experience in solving complex problems with a focus on efficiency, scalability and optimality. We expect you to be able to explain why you chose a particular data structure for a problem (e.g. why a Trie is better than a hash map for autocompletion) and analyze trade-offs (time vs. space).

• Practical experience: Minimum 2-3 years in development, where you applied CS concepts in practice (e.g. optimization of algorithms in production code). Knowledge of programming languages ​​(JS, C++, Java, Python) at a level sufficient for competitive programming.
