Are you a fit?
We're looking for a Senior AI Agent Engineer with a passion for building production-grade, tool-augmented AI agents that blend cutting-edge LLM techniques with solid software-engineering discipline. In this role, you'll design multi-step reasoning pipelines, wire them to business systems, and harden them for scale, safety, and maintainability — helping enterprise customers launch conversational agents that solve real problems, take real actions, and comply with real-world policies.
You'll play a key role in agent design and delivery, tool and data integration, LLM orchestration and planning, and continuous optimization — owning the full agent development life-cycle from scoping through monitoring and iterative tuning.
If you're passionate about AI R&D, agentic systems, and building reliable, guard-railed AI products, we'd love to meet you.
Qualifications:
- Excellent communication and collaboration skills. English B2 Advanced or C1
- 5+ years of software engineering experience in production environments (TypeScript/Node, Go, or Python) with strong API design, testing, and debugging habits
- Hands-on LLM experience (GPT, Claude, Gemini, or fine-tuned OSS models): prompt engineering, function/tool calling, model selection, and evaluation
- Retrieval-Augmented Generation (RAG): designing embedding pipelines and semantic search with Pinecone, Weaviate, etc.
- Agent orchestration expertise: LangChain/LangGraph, OpenAI Agents SDK, CrewAI, or equivalent frameworks for tool-augmented reasoning loops
- ML-/DevOps literacy: containerization, CI/CD, GPU/AI infra, caching, automated evals for nondeterministic systems
- Experience enforcing security guardrails & PII protection in user-facing AI products
Nice-to-have
- Real-time/voice agent delivery (e.g., SSE or WebSockets)
- Familiarity with emerging multi-agent protocols (MCP, A2A) or supervisor/critique agent patterns
- Domain experience in e-commerce, fintech, telecom, or large-scale customer support
- Prior work with automated prompt/agent regression testing frameworks
Why You'll Love This Role
- Build cutting-edge, tool-augmented AI agents at the intersection of AI R&D and backend engineering
- Work on multi-model orchestration, agentic reasoning loops, and enterprise-grade AI systems
- Collaborate with highly skilled engineers in an AI-native technology company
- Influence technical decisions and contribute to AI engineering best practices
- Enjoy continuous learning, professional development, and global collaboration opportunities
