? HOT JOB ALERT – AI ARCHITECT

? 100% Remote – Anywhere in Australia

? Salary: Open – Negotiable

? Permanent Full-Time | Start-up Workplace

Please note Previous start-up/scale up experience is a MUST - We are not looking for candidates coming from a large corporate/large organisation.

Our client is an ambitious AI start-up building next-generation AI infrastructure, and they're looking for an experienced AI Architect to take ownership of the architecture behind sophisticated, production-grade AI agents.

This is a hands-on technical leadership opportunity to design and build AI agents capable of executing high-value corporate transactions involving billions of dollars, while ensuring corporate policies, approvals, permissions and security controls are strictly adhered to.

You'll work directly with the founder and engineering team, shaping the technical direction and building the architecture, integrations and guardrails that make AI agents reliable in real-world environments.

What you'll be doing:

- Own the architecture and development of production AI agent systems.
- Build AI agents capable of executing complex, high-value transactions.
- Implement the right guardrails to ensure corporate policies, approvals, permissions and controls are followed.
- Design agent orchestration, tool calling, context management and persistent memory.
- Build reliable integrations using APIs, MCP tools and external platforms.
- Ensure agents can handle transactions, exceptions, failures and recovery securely.
- Establish AI evaluation frameworks, testing and production monitoring.
- Optimise performance,



scalability, response times and model costs.
- Provide technical leadership, architectural direction and mentoring while remaining hands-on.

What we're looking for:

- Proven experience architecting, building and operating production AI agent systems, with ownership from design through to implementation.
- Deep expertise in agent orchestration, including tool execution, state management, durable workflows, context engineering, memory and long-running tasks.
- Advanced Python skills and strong foundations in distributed systems, asynchronous processing, APIs, concurrency and database architecture.
- Experience designing complex integrations across multiple platforms, including event processing, data ingestion and reconciliation.
- Strong understanding of reliable AI-driven transactions, including typed APIs, idempotency, permission controls, human approvals and failure recovery.
- Experience building AI evaluation frameworks, regression testing and production monitoring to measure accuracy, reliability and task completion.
- Ability to optimise AI models, context, caching and execution for performance, quality, latency and cost.
- Strong security knowledge covering multi-tenant environments,



sensitive data, prompt injection and controlled tool access.
- Ability to set technical direction, make architectural decisions, mentor engineers and remain hands-on in production code.
- Previous start-up experience is a MUST – you need to understand the pace, ambiguity and challenges of building technology in a start-up environment.

Experience in travel technology, payments, financial services, transactional platforms, enterprise SaaS or voice AI would be advantageous, but is not essential.

Technology stack includes:

Python, FastAPI, Pydantic, LangGraph, LLM APIs, MCP/FastMCP, PostgreSQL, Redis, React, TypeScript, Next.js and LangSmith.

? Why consider this opportunity?

You'll work directly with the founder of an ambitious AI start-up, have genuine ownership of the AI architecture and help build the foundations of technology capable of transforming how complex corporate transactions are executed.
