•Design and implement cutting-edge Generative AI, LLMs, and Multi-agent systems (particularly advanced enterprise chatbots and decision-support tools) tailored for secure corporate environments
•Enforce software engineering best practices, including robust testing (unit, integration, E2E), CI/CD pipelines, and clean code architecture
•Ensure the security, scalability, and resilience of applications
•Take part in code reviews and contribute to the continuous improvement of processes and code quality
•Stay at the forefront of AI advancements, proactively identifying new tools and techniques to integrate into the stack
Requirements
•This is a software engineering-heavy role
•Proven track record of developing robust backend systems using Python and C#/.NET
•Hands-on, practical experience building and optimizing high-performance APIs using FastAPI
•Deep understanding of software environments, version control, automated testing frameworks, and architecture best practices
•Strong conceptual knowledge and practical experience implementing Gen AI, LLMs, Prompt Engineering, and Multi-agent systems
•Proven experience developing and deploying advanced chatbots or virtual assistants within complex, highly regulated corporate environments
•Solid understanding of model evaluation, integration, and ensuring model reliability/security in production
