Salary Range: AUD Annual Gross

Infosys is seeking a highly skilled and motivated Senior Consultant to join our DNA team. As a Senior AI Engineer, you will blend strong backend engineering skills with practical AI/LLM expertise to design and deliver high-quality, AI-enabled software. You will lead or collaborate with a cross-functional team of software engineers, DevOps engineers, QA, and product owners to build robust distributed systems that incorporate modern AI capabilities, particularly Large Language Models (LLMs).
You must be adept at Java (and possibly other JVM-based languages) for enterprise-grade systems, comfortable with Python for AI/ML workflows (e.g., PyTorch), and proficient in cloud deployment strategies. Beyond that, you'll integrate LLM APIs (OpenAI, Anthropic, Cohere, etc.), leverage retrieval-augmented generation (RAG) frameworks, and decide when to fine-tune models or use them as-is. As a power user of AI-based tools, you'll be expected to optimize your own coding through AI assistants, while also guiding best practices for prompt engineering, LLM orchestration, and system reliability.

• Leverage Spring Boot 3.x, Spring Security, Spring WebFlux to build production-grade solutions that can scale with AI usage
• Drive observability (monitoring, alerting, logging) and reliability practices, ensuring resilience and smooth user experiences
• Good grasp on generative model evaluation metrics for different use cases

Cross-functional Leadership:

• Partner with Product Owners to shape technical requirements and best approaches for AI-enabled product features, translating business goals into architectural designs
• Lead API design reviews and architecture discussions focusing on AI integration and alignment with our broader microservices ecosystem
• Foster a culture of knowledge sharing, especially around LLM usage, integration patterns, and AI code assistants (GitHub Copilot, etc.)
• Drive alignment with Platform Engineering and MLOps practices, ensuring automated deployment of AI-enabled services

Decision Making ScopeYou'll drive:

• Architectural direction for integration patterns that incorporate AI components (e.g., RAG, models, agents)
• Technology choices for new solutions around Gen AI usage, vector databases, and AI frameworks (SpringAI, LangGraph, LangChain, CrewAI)
• API standards and security patterns
• SLA and performance requirements

Technical RequirementsMust Have:

• 8+ years of commercial software development, focusing on integration/APIs
• Expert knowledge of Spring Framework ecosystem (particularly Boot 3.x, Security, WebFlux)
