SeniorPlatform Engineer (Software) – Sydney – $150,000–$170,000 + Super + ESOP
A high growth AI and lending technology business in Sydney with strong market traction and a genuine engineering culture. Small team, no platform team to hand off to, and a clear path to shape technical direction as the business scales. If you've spent your career owning both the infrastructure and the code on top of it, this is worth a conversation.
The role
Own and provision AWS infrastructure hands on - VPC, IAM, Secrets Manager, security groups, CI/CD
Design and maintain secure, production grade cloud environments from the ground up
Build and ship backend application code in TypeScript and Node.js
Raw SQL on PostgreSQL - joins, aggregations, query optimisation




Mentor mid and junior engineers and act as the primary technical point of contact for the business
The person
Genuinely owned AWS infrastructure in production - not handed it to a DevOps team
Solid hands on experience with VPC design, IAM, network security and CI/CD pipelines built from scratch
Solid backend engineering capability in TypeScript or Node.js
Comfortable writing production grade application code alongside infrastructure ownership
Clear communicator who can lead technically and bring others along
Python and FastAPI a genuine plus
