Full Job Description

Location 📍: Sydney, AU, Hybrid (3 days in office required) About Us 🚀 At Relevance AI, we’re building the home of the AI workforce. Our mission is simple: empower every team to delegate meaningful work to AI agents that think, act, and collaborate like experts. With Relevance AI, anyone can create and manage intelligent agents that handle workflows, decisions, and collaboration - all within one unified platform. Our technology already powers industry leaders such as Canva, Databricks, Confluent, Autodesk, Lightspeed, Rakuten, Aveva, Qualified, and Activision Blizzard, helping them scale excellence across operations, marketing, and sales. We’re backed by Bessemer Venture Partners, Insight Partners, Peak XV, and King River Capital, and raised our Series B in April 2025 to accelerate growth and push the boundaries of agentic automation. Headquartered in San Francisco and Sydney, we operate on a hybrid model and thrive on curiosity, collaboration, and execution - we move fast, think big, and win together. In 2025, we were proud to be named LinkedIn’s #1 Startup in Australia. If you want to define how the world works with AI, join us. The Role 🥳 We’re hiring for several Senior Software Engineers (Full-Stack / Back-End) to work across our core engineering teams in Sydney. Each team at Relevance AI is tackling a different frontier of the AI workforce — from the core agent and tool builder experience, to the conversational layer that powers real-time agentic chat, to the enterprise-grade platform capabilities that serve our largest and most demanding customers. Regardless of where you land, you'll be building systems that make AI usable, reliable, and production-ready. Our roles would be ideal for an engineer who enjoys solving deep technical problems, designing robust scalable systems, and owning complex projects end-to-end in close collaboration with product and customer-facing teams.
