Senior AI Platform Engineer
Relevance AI, Sydney, Australia
The role
As coding agents get more powerful, the biggest lever is no longer about shipping features faster — it's building the factory that ships every feature.
Relevance AI, Sydney, Australia
As coding agents get more powerful, the biggest lever is no longer about shipping features faster — it's building the factory that ships every feature.
In this role, you’ll own our developer experience, platform infrastructure, reliability and the factory that enables our whole engineering team to out-build with agents. You'll get to shape the foundations of our AI-native platform which everything else depends upon.
This is one of the highest leverage roles in the company: every system you build multiplies every engineer, and every agent, working alongside them — and the infrastructure and cost calls you make is what enables a small AI-native team out-ship a much larger one.
We are willing to sponsor engineers relocating from overseas to Australia.
In one-line: a staff platform builder who cares deeply about developer experience and owning the factory - product-minded, AI-native by default and driven to multiply everyone else's output.
Our Tech Stack (so far) 💻
Experience in our exact stack is not required — what matters more is how fast you can pick up a new one, and how deeply you already use AI coding agents as part of your daily workflow.
Location 📍: Sydney, AU, Hybrid (3 days in office required)
We believe that AI is fundamentally changing software and what it means to be an engineer. That means our team works differently:
We don't see platform engineering as a gated function or a black box. You'll bring deep expertise and help the wider team build real understanding and ownership of it, not just depend on you for it. That means working hands-on alongside application engineers, with knowledge flowing both ways.
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.
