Description

As a Senior SDET (Software Development Engineer in Test) with deep software engineering expertise and a strong grounding in cloud networking, you will architect, build, and scale a test automation platform that empowers developers to write end to end functional tests for the virtual networking layer of Apple's private cloud platforms. This is a software engineering role at its core: you'll design and ship production-grade frameworks, libraries, and developer tooling that make testing a first-class part of the engineering workflow. You'll spend roughly half your time engineering the automation platform itself (framework architecture, CI/CD integration, test infrastructure, developer experience) and the other half writing code, driving test strategy, and implementing automated test cases against the virtual networking stack in close partnership with developers.

Minimum Qualifications

Hands-on software engineering experience designing and building test frameworks, harnesses, or automation platforms (not just authoring individual test cases), spanning unit, integration, and end to end testing layers
Strong proficiency in one or more programming languages commonly used for building automation tooling (Go, Python), with the ability to write production-quality, maintainable code rather than scripts
Hands-on experience designing API contracts and working across interface technologies (JSON, ProtoBuf, REST, RPC, XML, etc.) to build testable, well-abstracted systems
Experience with Kubernetes, OpenStack, system virtualization, and infrastructure as code, with the ability to build and operate infrastructure, not just test against it
Strong communication skills with the ability to articulate architecture decisions, technical tradeoffs, test strategy, and results to both technical and non-technical audiences
Familiarity with observability systems (metrics, logging, tracing), including the ability to instrument and build observability into automation tooling itself, not just consume it for test validation and debugging

Preferred Qualifications

5+ years of relevant industry experience in software engineering
Prior experience building developer-facing testing tools or platforms
Experience with scale, performance and resiliency testing in networked/cloud environments
Bachelor's or Master's degree in Computer Science, Computer Engineering, or a related field
