We are looking for an AI Software Engineer to design, build, evaluate, and operate AI-powered capabilities within the Creatio platform.

You will join the AI teams building the agent platform that enables AI agents to safely perform real work in the product: call tools and APIs, read and write data, maintain context, follow permissions, and escalate to humans when needed.

The team also owns the core infrastructure for testing, monitoring, logging, observability, and cost/performance control, ensuring AI agents are reliable, scalable, secure, and production-ready.

This role combines strong software engineering expertise with hands-on AI engineering experience. You will work on enterprise-grade AI solutions, including assistants, copilots, knowledge systems, semantic search, RAG-based capabilities, and agentic workflows.

• Integrate LLM providers, tools, enterprise data sources, and MCP-based solutions.
• Develop and maintain backend services using C# and .NET.
• Build evaluation frameworks, quality gates, and observability practices for AI solutions.
• Monitor and improve the quality, latency, cost, reliability, and security of AI capabilities.
• Apply AI coding assistants and engineering agents as part of the daily development workflow.

Requirements:

• Strong experience with C# and .NET.
• Hands-on experience with LLMs, prompt engineering, function calling, and structured outputs.
• Understanding of agent architectures, MCP, RAG, embeddings, vector search, and semantic search.
• Experience with AI evaluation, observability, security, and Responsible AI practices.
• Solid understanding of API design, distributed systems, and software architecture.
• Experience with SQL databases, testing, CI/CD, and cloud-native development.
• DevOps fundamentals, including Docker containerization and basic Kubernetes knowledge.
• Strong knowledge of engineering best practices and production-grade software development.

What to expect from us:

• Growth & Development: Clear career paths, mentorship opportunities, and access to continuous learning to help you reach your full potential.
• Flexibility & Well-Being: We provide flexible work arrangements and initiatives that empower you to manage your schedule effectively, stay productive, and thrive both personally and professionally.
• Recognition & Impact: A culture that celebrates achievements, values your ideas, and empowers you to make real contributions from day one.
• Innovative Culture: Be part of a company that embraces new ideas, modern technologies, and bold thinking to stay ahead of the curve.
• Benefits & Rewards Package: We provide competitive compensation and benefits designed to support you and your family. Our rewards approach goes beyond salary, recognizing your contributions and commitment. The exact package may vary depending on your country of residence and employment type.
