Senior AI-First Software Engineer - Next.js & TypeScript

Matrix Education; Sydney; On-site; AUD 180,000 - 240,000; Full time

Job summary

Matrix Education in Sydney seeks a senior software engineer to help build its in‑house product platform using Next.js, TypeScript and Node. You will work directly with our Head of Technology and Head of Digital Product to ship student, parent and teacher‑facing software.

You’ll design end‑to‑end AI‑first development lifecycle, automate CI/CD, and integrate Salesforce and Snowflake via a shared API layer. You’ll push back on scope to balance engineering cost and outcomes.

Qualifications

• Shipped Next.js and TypeScript in production with real users behind it.
• 5+ years building production software, including at least 12 months where AI agents did meaningful parts of the work.
• Strong with Node, REST API design, and integrating third‑party SaaS systems that do not behave the way the documentation claims.
• Comfortable with SQL and Postgres at a production level.
• You have designed and scaled modern, AI‑first or highly automated CI/CD and agentic development lifecycles, not just worked inside traditional pipelines.
• You can describe a product decision you changed because of something you knew about the code.

Responsibilities

• Build and ship product in a small team.
• Join the storymap and prototype work at the start of a build, pushing back on scope when engineering cost does not match the outcome.
• Integrate with Salesforce, Snowflake and other Enterprise systems through the shared business API layer.
• Own the review loop on agent output: identify logic errors and security gaps, and decide what to keep or rewrite.
• Ship at least one customer‑facing release in the first quarter.
• Define and scale the agentic development lifecycle.
