Senior AI Agent Engineer

About the Role

We are seeking an engineer who doesn't just "talk" to LLMs but builds autonomous, resilient systems. You will design multi-agent architecture that can reason, use tools, and recover from failures independently.

Your primary goal is to bridge the gap between "cool demos" and "production-grade reliability." You will be responsible for deploying agents across various business sectors (e.g., Finance, Operations, Customer Success), ensuring they are not only intelligent but also safe, cost-effective, and predictable in a production environment.

Key Responsibilities

● Agent Orchestration: Design and implement stateful, multi-turn agent workflows using frameworks like LangGraph, CrewAI, AutoGen, PydanticAI, Swarm, Haystack, or Bee Agent Framework.

● Proactive Reliability & Guardrails: Architect systems that prevent production meltdowns. Implement circuit breakers, "human-in-the-loop" triggers, and input/output guardrails to stop infinite loops, prompt injections, and hallucinated tool calls before they reach the end user.

● Multi-Sector Tooling: Build and maintain high-precision API integrations (tools) that allow agents to interact with diverse business systems (ERPs, CRMs, custom databases) deterministically.

● Observability & Tracing: Set up advanced tracing (e.g., LangSmith, Langfuse, or Arize Phoenix) to debug complex reasoning chains and monitor agent trajectories in real-time.

● Rigorous Evaluation (Evals): Develop automated "Golden Datasets" and evaluation frameworks (using RAGas, DeepEval, G-Eval, LangSmith Evaluators, or custom model-based grading) to measure agent success rates and prevent regressions before every deployment.

● Cost & Latency Optimization: Manage the "token budget" by implementing tiered model routing (e.g., using Gemini 3 Flash for initial reasoning and Ultra for final verification) and optimizing context window usage.

Requirements

Required Qualifications

● 3+ years of Software Engineering experience, with a background in Python and FastAPI (or similar).

● 1+ year of experience specifically focused on LLM-based Agents in a production environment.

● Deep Expertise in Agentic Patterns: Proven experience implementing ReAct, Plan-and-Execute, or Multi-Agent Supervisor architectures.

● Production Infrastructure: Hands-on experience with modern Vector Databases and Search Engines (e.g., Pinecone, Milvus, Weaviate, Qdrant, Chroma, or pgvector) and semantic caching strategies.

● Robustness Mindset: A track record of handling non-deterministic failures (e.g., implementing custom retry logic and fallback strategies for failed tool calls).

Preferred Qualifications (The "Plus" Factors)

● Experience with Fine-tuning smaller models (e.g., Llama 3) for specific tool-calling tasks to reduce latency.

● Knowledge of Data Privacy (handling PII in agent prompts) and AI Security best practices.

● Prior experience building agents for specialized sectors like Fintech or Supply Chain.
