Principal / Senior Software Engineer

Take genuine ownership of architecture and technical direction

Melbourne VIC | Remote-First | Permanent TypeScript / Node.js | React Native | AWS | Terraform

An established and growing Australian technology business is looking for an experienced

Principal / Senior Software Engineer

to take on a highly influential position within its engineering team.

This is an opportunity for either an established Principal Engineer or an accomplished Senior/Lead Engineer ready to step into broader technical ownership.

You'll remain hands-on while helping shape architecture, engineering standards and technical direction across an established software platform.

This is an individual contributor position with

no direct reports

– ideal for someone who wants senior-level influence while remaining close to the technology.

The position is

predominantly remote , with a preference for someone based in Melbourne who can occasionally spend time with the wider team in the office. There is no regular weekly office requirement.

The Role Working closely with senior technology leadership and the wider engineering team, you'll help solve some of the more complex technical challenges across an established platform as it continues to evolve and scale.

You'll:

Influence architecture and technical direction across multiple applications and services

Remain hands-on across TypeScript, Node.js and React Native

Solve complex problems around scalability, performance, reliability and cost

Make pragmatic architectural and technology decisions

Modernise existing systems incrementally rather than relying on large-scale rewrites

Work extensively across AWS and Infrastructure as Code environments

Improve security, privacy and engineering standards

Act as an escalation point for complex production issues

Identify opportunities to simplify systems and reduce duplicated engineering effort

Contribute to longer-term technical roadmaps and priorities

Mentor engineers and help raise technical capability across the team

Balance hands-on engineering with broader architectural ownership

About You We're open to speaking with experienced

Senior, Lead, Staff or Principal-level engineers

who have built and operated production software and are comfortable taking ownership beyond individual features.

Ideally, you'll bring strong commercial experience across:

TypeScript / JavaScript

Node.js

React Native

AWS

Terraform / Infrastructure as Code

API and backend architecture

SQL and relational database design

CI/CD and modern deployment practices

Mobile application development and release processes

Designing and operating production software at scale

Modernising existing or brownfield platforms

Application security and privacy

Technical mentoring and architectural decision-making

Commercial

PHP

experience would be advantageous, although we're equally interested in strong engineers who are comfortable taking ownership of technologies outside their primary stack.

Additional Experience of Interest Exposure to any of the following would be highly regarded:

Multi-tenant SaaS platforms

High-volume transactional applications

Subscription or recurring billing systems

App Store and Google Play release engineering

Video or media platforms

Data pipelines and complex integrations

ERP integrations

Internationally distributed software products

Security, privacy and regulatory compliance

Why Consider This Opportunity? This isn't a role where you'll simply be handed tickets from a predefined backlog.

You'll have the opportunity to influence how an established platform evolves, solve meaningful technical problems and work closely with senior technology leadership on the decisions that shape the engineering environment.

You'll have:

Genuine influence over architecture and technical direction

Direct access to senior technology leadership

Complex, real-world engineering challenges

The opportunity to remain genuinely hands-on

A modern TypeScript, React Native, Node.js and AWS environment

Scope to improve engineering standards and practices

An established platform with continued growth ahead

A predominantly remote working environment

Flexibility without a regular weekly office requirement

The opportunity for a strong Senior/Lead Engineer to step into broader Principal-level ownership

Melbourne-based candidates are preferred

due to occasional in-person collaboration, although strong candidates elsewhere in Australia may also be considered.

Requires Australian Full Work Rights. No Sponsorship Available.

If you're an experienced software engineer who enjoys solving difficult technical problems, improving established systems and having genuine influence over technical direction, we'd be keen to hear from you.
