Summary ✨ AI‑Generated

Join a newly formed engineering team building foundational backend infrastructure that connects AI agents with real business systems. You will own integration services, agent tooling, domain boundaries, and scalable pipelines, while applying deep Java expertise and strong system-integration judgment. The role offers substantial architectural ownership and the opportunity to define new technical patterns rather than maintain legacy systems.

Highlights

High-impact opportunity to build a new AI integration layer from the ground up, with significant technical ownership, strong compensation, and the chance to shape architecture for a brand-new engineering team.

Description

Senior Backend Engineer Sydney (hybrid) Up to $210k + super & bonuses We're building the integration layer for AI inside a fintech's collaboration platform. Four engineers. Brand new team. First crack at wiring collaboration tooling into an AI SDLC - not a legacy system to patch, a layer to define. What you own MCP servers, exposed by the collaboration stack, that let agents reach real domain objects instead of just talking.Bots that are actually agents - tool-calling, knowledge-grounded, wired into internal systems that matter.The pipelines and domain-object boundaries a much larger AI platform team builds on top of. What you bring Java depth. Not exposure - depth. You make the right call on a Java system without being taught its intricacies.Integration instinct. HubSpot, Salesforce, Atlassian - the vendor doesn't matter. Knowing how to integrate cleanly with a third-party system does.Discovery before code. You ask what needs to be built before you build it, and you design it structured, not sprawling.Enough AI fluency to grow fast into MCPs, skills, and agents. You don't need to be there yet. You need to actually want to be. No Jira or Atlassian background required here. A strong generalist with real integration judgment beats a specialist in one vendor's stack. If this sounds like your kind of problem to solve, apply now.
