Job Description
Build our agentic services platform from zero to one. Own backend architecture from initial concept through production deployment to enterprise scale.
About this role
We're looking for an AI Engineer to build and improve the intelligent core of our agentic platform. You'll work on multi-agent systems, LLM orchestration, and the AI capabilities that power our enterprise automation. This is a hands-on role where you'll design, implement, and optimize AI systems that execute real business processes — not just chatbots, but agents that get work done.`
Responsibilities
- Design and build multi-agent systems that orchestrate complex business process automation
- Work with agent frameworks (LangChain, LangGraph, CrewAI, AutoGen, or similar) to build reliable, production-grade agentic workflows
- Implement and optimize LLM-powered reasoning, planning, and tool-use capabilities
- Build RAG pipelines and knowledge retrieval systems to ground agents in enterprise context
- Fine-tune and evaluate Small Language Models (SLMs) for domain-specific tasks
- Develop prompt engineering strategies and evaluation frameworks for agent reliability
- Collaborate with integration engineers to connect agents with enterprise systems
- Debug and improve agent behavior based on production feedback and failure analysis
Requirements
- 3-5 years of experience in software engineering, with at least 1-2 years focused on AI/ML or LLM applications
- Strong programming skills in Python
- Hands-on experience with agent frameworks: LangChain, LangGraph, CrewAI, AutoGen, Haystack, or similar
- Experience building applications with LLM APIs (OpenAI, Anthropic, Azure OpenAI, open-source models)
- Understanding of prompt engineering, chain-of-thought reasoning, and tool-use patterns
- Familiarity with RAG architectures, vector databases, and embedding models
- Ability to debug complex AI systems and iterate based on real-world failures
- Strong communication skills and ability to work cross-functionally
Nice to Have
- Experience fine-tuning LLMs or training custom models (LoRA, PEFT, etc.)
- Familiarity with browser/computer-use agents and UI automation
- Experience with ML infrastructure: model serving, GPU optimization, inference at scale
- Background in reinforcement learning or decision-making systems
- Understanding of enterprise IT, ITSM, or business process automation
- Startup experience or comfort working in fast-paced, ambiguous environments
