Ever wanted to be the test specialist behind one of the country's more ambitious engineering programs?
Horizon Digital is a Perth-based custom software and AI consultancy. We build complex, high-impact digital solutions for enterprise clients across government, resources, and private sector, and we do it fast, with agile delivery baked in from day one.
We're embedded with a major Perth-based client on a serious industrial transformation. The software our tester validates runs mission‐critical AI and distributed systems in a high‐consequence operational environment. Quality is on the critical path. The platform is past proof‐of‐concept and moving toward full deployment, and the systems that get it there need to behave reliably under real operational pressure.
We're looking for a Software Test Specialist to own the test strategy, build out automated test suites, and validate the ML‐enabled services and distributed systems before they reach live operations.
What you'll be doing
* Building and owning the test strategy across the platform, from unit through to end‐to‐end
* Designing and maintaining automated test suites for distributed services and APIs
* Validating ML‐enabled services: data flow, inference behaviour, and model output quality
* Running performance, load, and resilience tests under real operational pressure
* Wiring automated testing into CI/CD so regressions are caught before they reach the field
* Working closely with engineers and data scientists on testability and quality standards
* Leading defect analysis and root cause investigations when things go sideways
What you'll bring
* 4-8 years in software testing or quality engineering with real depth, not breadth
* Hands‐on experience testing distributed and backend systems, not just UI
* Strong automated testing frameworks. You write test code, not just click‐through cases
* API and microservices testing, including contract testing and integration coverage
* Comfortable in containerised environments: Docker and Kubernetes
* Performance, load, and resilience testing using tools like k6, Locust, JMeter, or Gatling
* Linux comfortable, with scripting in Python or Bash
* CI/CD integration as a default way of working, not an afterthought
* Validating ML‐enabled services in production: data flow checks, inference assertions, drift detection
* Real‐time, high‐availability, or operational systems exposure
* Familiarity with GitHub Actions, Octopus Deploy, or Artifactory
Why Horizon Digital?
* Work on genuinely complex, cutting‐edge AI and distributed systems
* Hybrid working with real flexibility
* A tight‐knit, high‐performing team that moves fast and backs each other
* Real ownership where your work directly shapes how mission‐critical systems run
* 12‐month engagement on a program that genuinely matters
