Software QA Engineer - Swift macOS

We are looking for a QA engineer who uses Swift to test software that helps organizations make sense of their data. This is an opportunity to join a team building solutions where quality is the product. You'll work across macOS system services, multi-process architectures, and performance-sensitive components to make sure what we ship works the way customers expect. To be successful, you will bring creative energy to collaboration, communication, and producing high-quality deliverables.

You'll work on problems that matter. The software you test protects customer data, keeps critical systems running, and delivers tools that organizations from schools to hospitals trust every day. We're looking for someone who solves problems, takes initiative, and cares about the people who use what we build.

Design, develop, and maintain automated test suites in Swift using XCTest and Swift Testing frameworks.
Test macOS server software across process lifecycle events including installation, upgrade, crash recovery, and uninstall.
Validate REST API endpoints, SSE streams, and WebSocket connections through functional and integration testing.
Profile application performance using Xcode Instruments and identify regressions in latency, memory, and resource usage.
Investigate and triage concurrency issues using Thread Sanitizer and strict concurrency checking.
Collaborate with developers to define testability requirements early in the development cycle.
Build and maintain CI pipelines using xcodebuild for automated test execution across configurations.
Execute long-running stability and soak tests to validate system reliability under sustained load.
Test code signing, notarization, and installer packaging workflows for macOS distribution.
Participate in sprint planning, backlog grooming, and release readiness reviews.

3+ years of experience quality engineering experience in modern web technologies and using XCTest and Swift Testing framework
Computer Science-Software Engineering Degree or equivalent software engineering experience
Demonstrated experience testing software using Behavior Driven Development (BDD) or Test-Driven Development (TDD) methodology to define and execute scenario-based test coverage

Experience testing actor-based Swift concurrency, including data race detection with Thread Sanitizer (TSan) and strict concurrency checking. Familiarity with long-running stability and soak testing.
Strong understanding of RESTful API, OpenAPI specification, SSE (Server-Sent Events), and service testing. Experience testing solutions utilizing WebSockets and JWT/OAuth validation.
Familiarity with performance testing on macOS, including Xcode Instruments profiling (Time Profiler, Allocations, Leaks) and resource constraint testing.
Experience testing AI-integrated features or machine learning (ML) pipelines (Agentic, LLC etc.), including validating model outputs, latency, and deterministic behavior. Familiarity with Model Context Protocol (MCP) or similar tool-use frameworks
