Integrating LLMs and AI services into .NET- and Python-based systems
Designing and implementing AI-assisted workflows, copilots, or intelligent automation features
Working with agentic AI patterns (e.g., task orchestration, tool-using agents, workflow automation)
Applying prompt engineering, evaluation techniques, and guardrails to ensure reliability and compliance
Collaborating with data and platform teams to operationalize AI—not just prototype it
Deep ML expertise is not required—we’re looking for strong engineers who understand how to apply AI capabilities in real products.
