Performance Architect (Remote from anywhere in AUS).

Must hold PR or Citizen.

We are seeking an elite level
Performance Architect
with deep expertise in large-scale, high-availability systems and advanced cloud architecture. You will play a key role in ensuring our platforms deliver exceptional performance, scalability, and reliability—meeting the demands of mission-critical, globally distributed services.

As a senior technical contributor, you'll architect, design, test, and optimise architectures capable of handling significant scale, leveraging your experience as a Tier 1 AWS Cloud Architect (or equivalent) to ensure robust infrastructure performance under heavy load. You will work closely with engineering, DevOps, and product teams to create performance-focused solutions that meet stringent SLAs.

What You'll Be Doing:

  • Architect, implement, and optimise large-scale, high-throughput systems.
  • Lead performance engineering, profiling, and tuning for distributed applications and microservices.
  • Collaborate with cross-functional teams to optimise application performance at both the infrastructure and code level.
  • Ensure high availability, low latency, and fault-tolerant system design.
  • Build monitoring and observability frameworks to track performance trends.
  • Provide architectural recommendations for scaling infrastructure and services efficiently.

What We're Looking For:

  • 7+ years of experience working with large-scale, mission-critical systems with zero downtime in an elite performance environment.
  • Proven track record of architecting performance applications and system design.
  • Expert-level understanding of database internals, including locking mechanisms (row vs. table, optimistic vs. pessimistic), query execution plans, and their performance trade-offs.
  • In-depth knowledge of network protocols and their performance implications, including a strong command of the TCP/IP stack and the practical differences between HTTP/1.1 and HTTP/2.
  • Advanced knowledge of Linux/Unix system administration and kernel tuning for high-performance applications (e.g., ulimit, swappiness, network stack tuning).
  • Deep understanding of system architecture and networking, including caching, distributed systems, Kubernetes (k8s) architecture, and networking protocols37.
  • Proficiency with advanced monitoring and observability tools like Dynatrace for generating performance metrics and actionable insights.
  • Expertise in the principles of code profiling and optimisation, including algorithm selection, data structure efficiency, and concurrency patterns.
  • Strong problem-solving skills, with the ability to balance performance, scalability, and technical constraints.
  • Excellent communication skills, with experience collaborating with cross-functional teams and presenting architectural rationales to diverse audiences.
