Role Title: Engineering Architect –(AI-Native Platform)

Power the Future of AI & Why This Role Matters

As an Engineering Architect – (AI-Native Platform), you will define the technical architecture powering Sirion's AI-native, multi-tenant Contract Lifecycle Management (CLM) SaaS platform. You will architect elastically scalable, cloud-native backend systems designed AI-native and agentic-first, capable of powering intelligent, autonomous AI capabilities across contract understanding, reasoning, negotiation, workflow automation, and enterprise integrations.

This role combines deep backend engineering expertise with AI platform architecture and the ability to design AI-native, agentic-first platforms. You will partner closely with Product, Engineering, Applied AI, Data Science, and Platform teams to build secure, resilient, and high-performance distributed systems capable of supporting enterprise-scale agentic AI workloads. You will play a key role in shaping Sirion's backend architecture, championing a customer-first engineering culture, driving engineering excellence, and enabling AI-first product innovation that scales with our enterprise customers.

How You'll Make an Impact

• Define and drive the architecture of Sirion's next-generation AI-native backend platform, ensuring scalability, resilience, security, and maintainability.
• Architect large-scale distributed systems, cloud-native microservices, event-driven platforms, and enterprise APIs that elastically scale to support millions of contract transactions across a growing multi-tenant customer base.
• Design backend platforms enabling Agentic AI capabilities including autonomous agents, multi-agent collaboration, reasoning, planning, tool orchestration, memory management, and workflow automation.
• Architect enterprise-grade Retrieval-Augmented Generation (RAG) pipelines, semantic search platforms, vector search infrastructure, and knowledge retrieval systems.
• Build highly scalable backend services supporting LLM inference, AI orchestration, model routing, prompt execution, and AI workflow management.
• Drive architecture for API gateways, service mesh, asynchronous messaging, event streaming, distributed caching, and real-time processing platforms.
• Establish engineering best practices around system design, architecture governance, scalability, reliability and SLA-driven service quality, observability, security, performance optimization, and operational excellence, keeping the customer experience at the centre of every architectural decision.
• Partner closely with AI Engineering teams to integrate Large Language Models, Agentic AI frameworks, and intelligent automation capabilities into production systems.
• Mentor senior engineers and technical leads through architecture reviews, design reviews, and technical leadership across multiple engineering teams.
• Evaluate emerging technologies across distributed systems, cloud platforms, AI infrastructure, backend engineering, and enterprise architecture to accelerate product innovation.
