*Job Description: Senior AI Systems & Orchestration Engineer*
*Role Overview*
We are seeking a high-caliber Senior Engineer to lead the development of an autonomous Multi-Agent Operating System (A-OS). You will architect the "Kernel" that orchestrates specialized agents, manages long-term state across complex real-world workflows, and bridges the gap between AI reasoning and deterministic execution. This role is designed for an engineer who operates at the bleeding edge of the agentic revolution, utilizing autonomous development tools to build self-sustaining systems.

*Key Responsibilities*
Orchestration & State Management: Design and implement the core engine (using LangGraph, Temporal.io, or specialized Node.js frameworks) to manage agent-to-agent communication and "hibernation" states for long-running asynchronous processes.

Agentic Development: Leverage leading agentic IDEs and CLI tools—specifically Claude Code, Windsurf, and Cursor—to accelerate the development lifecycle and implement self-correcting code patterns.

Agent Swarm Engineering: Build and fine-tune specialized autonomous agents utilizing a hybrid model approach, including Gemini 1.5 Pro/Flash, GPT-4o, Claude 3.5 Sonnet, and Grok APIs.

Browser Automation: Develop robust, "self-healing" automation using Playwright or Puppeteer to navigate complex web portals, bypass bot detection, and handle strong authentication (2FA).

The Validation Kernel: Implement a deterministic validation layer to ensure AI-generated outputs comply with strict JSON schemas and industry-specific regulatory requirements.

Event-Driven Infrastructure: Architect a scalable Dockerized microservices environment using Kafka or RabbitMQ for reliable message distribution.

Technical Requirements
Agentic IDE Proficiency: Expert-level experience with leading agentic development tools. You must be proficient in using Claude Code, Windsurf, or Cursor to build, test, and debug complex autonomous systems.

AI Model Expertise: Deep experience integrating and prompting the latest LLMs, with a specific focus on Gemini 1.5 Pro (leveraging its large context window), Claude 3.5, and GPT-4o.

Languages: Mastery of Node.js (TypeScript) and Python 3.11+.

AI Orchestration: Extensive experience with LangChain, LangGraph, CrewAI, or custom multi-agent frameworks.

Databases: Advanced knowledge of PostgreSQL (JSONB) and Vector Databases (Pinecone, Milvus, or pgvector).

Automation: Extensive experience with Playwright, including session persistence and headless browser management.

Messaging: Proven track record with event-driven architectures and high-throughput message brokers (Kafka / RabbitMQ).

*Preferred Qualifications*
Experience in Gov-Tech, FinTech, or highly regulated industries involving complex paperwork.

Understanding of PKCS#11 or hardware-based digital signatures (Smart Cards/USB tokens).

Experience building "Human-in-the-Loop" (HITL) interfaces where AI agents pause for user intervention.

Familiarity with automated document generation (PDF/JSON) and verification.

*Technical Stack Information*
Execution: Docker & Cloud Run / Kubernetes.

Intelligence: Hybrid LLM approach (Gemini, Claude, GPT, Grok).

Frameworks: Event-driven Microservices with long-term state persistence
