Senior Ai Engineer

Talent Acquisition Associate Lead- APAC at Infosys
Location: Sydney
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.
Key Responsibilities
Technical Leadership & Architecture:
Architect and implement high-throughput APIs that integrate with and leverage AI services
Make key architectural decisions on API security, scalability, reliability, and how to incorporate LLMs (OpenAI, Anthropic, etc.) into our platform
Lead integration solutions using Spring Boot 3.x, reactive patterns (WebFlux), and API gateways (Apigee) while mentoring other developers
Champion improvements in integration best practices (performance, security) with a focus on enabling AI-driven applications and ensuring efficient content retrieval workflows where relevant
Collaborate with AI and platform engineers to design APIs for model inferencing (e.g., hosting endpoints for LLM queries, vector search, or other AI-driven tasks)
Implement secure API patterns (OAuth2, JWT, etc.) to protect sensitive data, particularly when fine-tuning or retrieving embeddings for AI models
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
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 Scope
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 Requirements
Must Have:
8+ years of commercial software development, focusing on integration/APIs
Expert knowledge of Spring Framework ecosystem (particularly Boot 3.x, Security, WebFlux)
Mastery of API security, including OAuth2, JWT, and API key management
Track record of delivering high-performance, secure system designs
Strong command of AWS, Azure or GCP cloud services
Experience consuming LLM APIs (OpenAI, Anthropic, etc.), orchestrating prompts or agentic workflows
Familiarity with RAG (retrieval-augmented generation), term/embedding-based search
Daily usage of AI coding assistants (e.g., GitHub Copilot) to speed up development workflows
Nice to Have
:
Real-time data processing and streaming architecture experience
Hosting model endpoints using bedrock or similar
Experience with Kafka or similar message brokers
Skills and Abilities
Technical Excellence:
Advanced system architecture and API design capabilities
Expert-level API security implementation knowledge
Deep understanding of cloud-native architectures
Strong performance optimization and troubleshooting skills
Advanced DevOps and automation practices
Leadership & Impact:
Strong stakeholder management capabilities
Advanced problem-solving and analytical skills
Clear technical documentation abilities
Experience driving technical initiatives across teams
