About REA Group:
In 1995, in a garage in Melbourne, Australia, REA Group was born from a simple question: “Can we change the way people experience property”
Thirty years later, REA Group is a global digital real estate leader operating across multiple continents, building large-scale, consumer-facing platforms used by millions every day.
Our success comes from staying true to a day-one mindset—combining innovation, curiosity, and long-term thinking to evolve complex systems that power critical customer journeys.
REA Cyber City is an extension of REA Group’s global technology organization. Teams here work closely with counterparts in Australia and other regions to design, build, and operate core platforms and capabilities. Engineers in Cyber City contribute directly to REA’s long-term technology strategy, solving real-world problems at scale and shaping systems that need to perform, adapt, and endure over time.
If you’re excited by the challenge of building resilient systems, working on meaningful problems, and growing with a global engineering organization—read on.
Senior Lead Engineer – Full Stack
What the role is all about:
We’re seeking a Senior Lead / Staff Engineer who operates as a squad architect and systems thinker, owning complex technical problems end-to-end and shaping the evolution of REA’s platforms at scale.
This role is designed for a senior individual contributor who leads primarily through technical depth, architectural judgement, and operational ownership. The focus is on designing, building, evolving, and operating reliable systems over time—while influencing engineering standards, mentoring engineers, and enabling predictable delivery across squads.
You will work closely with engineers, Engineering Managers, Product Managers, and stakeholders to solve domain-wide problems and ensure systems remain scalable, secure, and maintainable as REA continues to grow.
Core Behavioral Signals:
- Shapes architecture and ensures long-term technical direction aligned with platform and domain goals.
- Drives system health, stability, performance, and maintainability.
- Solves domain-wide and cross-team technical problems.
- Enforces quality, standards, and strong engineering practices.
- Resolves complex dependencies across squads and systems.
- Influences technical strategy and represents engineering in decision forums.
What you’ll do:
Technical Execution:
- Design, build, review, and operate production-grade full-stack systems using modern engineering practices.
- Own delivery of complex, high-impact features and subsystems, leading by example in code quality, correctness, and performance.
- Work hands-on across frontend and backend codebases using technologies such as React, JavaScript, TypeScript, Node.js, and Java.
- Drive high engineering standards through pairing, deep code reviews, and clear technical guidance.
Design & Architecture:
- Own architecture decisions for complex systems, documenting and communicating trade-offs through design reviews and Architecture Decision Records (ADRs).
- Shape subsystem and platform-level architecture aligned with REA’s long-term technical strategy.
- Evaluate and articulate trade-offs across performance, reliability, security, cost, and maintainability.
- Design and evolve APIs, services, and data flows that scale across teams and domains.
- Design or contribute to event-driven and asynchronous architectures; experience with streaming platforms (e.g. Kafka) is a plus.
System Ownership & Operational Excellence:
- Own production systems end-to-end, including reliability, scalability, performance, observability, and technical debt management.
- Own application performance across the stack by identifying bottlenecks, driving optimizations, and ensuring systems meet latency and scalability targets.
- Design and operate containerized workloads using Docker and Kubernetes in production environments.
- Ensure systems are observable, resilient, and designed for safe failure and recovery.
- Champion continuous improvement in operational practices and developer experience.
Delivery Leadership:
- Contribute to planning and sequencing of work, helping teams balance scope, quality, and delivery timelines.
- Identify cross-team dependencies and technical risks early, unblocking teams through sound technical decisions.
- Partner closely with Engineering Managers and delivery leads to improve predictability without compromising quality.
Technical Leadership & Mentorship:
- Mentor and coach engineers through design reviews, technical discussions, and hands-on guidance.
- Raise the technical bar across squads by reinforcing strong engineering practices and architectural consistency.
- Influence without formal authority, earning trust through technical credibility and clarity of thinking.
What we’re looking for:
- Proven experience operating as a senior contributor on complex, production systems.
- Strong hands-on experience with modern full-stack technologies, including React, JavaScript, TypeScript, Node.js, and Java.
- Experience designing and operating systems on AWS and/or GCP, including cloud-native services.
- Strong understanding of CI/CD principles, including trunk-based development, automated testing, progressive delivery, and rollback strategies.
- Experience designing and operating containerized systems using Docker and Kubernetes.
- Demonstrated ownership of system design, performance, reliability, and long-term maintainability.
- Ability to clearly communicate architectural decisions, trade-offs, and technical direction to diverse stakeholders.
- Strong mentoring mindset with the ability to elevate others without direct people management responsibility.
- Comfort working in a fast-moving environment where priorities evolve and pragmatic trade-offs are required.
Nice to have:
- Experience with event-driven architectures, streaming platforms (e.g. Kafka), or large-scale asynchronous systems.
- Exposure to platform engineering or shared services models.
- Experience evolving legacy systems while delivering new capabilities.
Why join REA Cyber City:
- Work on globally impactful products used by millions.
- Be part of a growing global engineering organization with strong technical standards.
- Influence systems, teams, and culture from an early stage.
- Collaborate closely with global leaders and technologists.
- Grow as a people leader, delivery owner, and technology leader.
The values we live by:
