Senior QA Engineer: API, Performance & Reliability

Insight Global; Atlanta (GA); On-site; USD 90,000 - 130,000; Full time

Job summary

Insight Global is seeking an experienced QA Engineer to own the verification stage after builds, provisioning environments and deploying artifacts for release decisions. You will test backend APIs, ensure API compatibility, and build end-to-end Playwright coverage against deployed environments.

You will gate releases of shared services, manage test environments, and drive secure, scalable testing across nondeterministic systems. Collaboration and clear communication are essential to succeed.

Qualifications

• 5+ years in software quality engineering or related field, including 3+ years building automated Python test suites.
• Strong API testing experience against HTTP services with authentication, streaming and timeouts.
• Deep pytest experience with fixtures, parametrization, async tests, and large, fast, comprehensible suites.
• Experience testing deployed software from outside the repository; API compatibility and schema drift testing.
• CI/CD experience, ideally with GitHub Actions; post-build verification stages and release gates.
• Experience provisioning containerized test environments (Testcontainers, Docker Compose).
• Ability to reason about nondeterministic systems and manage flakiness in AI or distributed pipelines.
• Ability to read unfamiliar production code and identify real risk areas; strong debugging in async/distributed contexts.
• Clear written communication and actionable defect reports; collaborate with engineers on testability.

Responsibilities

• Own the verification stage after a build: provision the environment, deploy the artifact, run tests, and produce the release decision.
• Test backend services as black box across APIs (routing, failover, retries, timeouts, rate limits, error mapping).
• Build API compatibility coverage to catch breaking schema changes.
• Create end-to-end Playwright coverage against deployed environments: SSO, streaming, long-running generation, and document verification.
• Gate releases of shared services and libraries to ensure safety before shipping.
• Manage test environments: containerized dependencies, seeded data, isolation, teardown.
• Add performance and load coverage for streaming endpoints and long-running jobs.
• Test security-relevant behavior at service boundaries: auth, session handling, CSRF protection, RBAC, tenant isolation, content handling.
• Run quality measurement of model output on a schedule and report trends over time.
• Maintain a trustworthy suite: flake detection, clear diagnostics, actionable failures.
• Triage external defects: reproduce, narrow, and provide failing cases for owners.
• Set verification standards that downstream services inherit and document them clearly.
