SustainAbility Consulting in Sydney is seeking a Senior Backend Engineer to own the core platform: a multi-tenant SaaS built on Laravel, MySQL and Postgres, running on containers in the cloud. You will architect for scale and set standards for backend design, review, and shipping.
You will move legacy server-rendered views to clean APIs, design multi-tenant data architectures, and ensure security by default while enabling CI/CD, migrations, and observability.
