As an Associate SDET, you'll support web and mobile interface testing, focusing on E2E, integration testing, and automated scripts using Python and Playwright, while collaborating in an Agile environment.

The Senior Software Test Engineer develops custom test systems, instrument drivers, and applications using LabVIEW/TestStand, collaborating with customers and cross-functional teams to ensure system compliance and readiness for deployment.

Lead technical ownership of a global platform for safe change: distributed key-value storage, progressive configuration delivery, testing and health-mediation. Write production code, design systems, review senior proposals, integrate LLMs, and drive cross-team initiatives to improve reliability, rollout safety, and developer productivity.

As a Software Development Engineer in Test, you'll create and conduct automated tests, resolve technical issues, and collaborate with development teams to ensure software quality.

Design, build, and maintain scalable test automation frameworks and tooling (Playwright, C#, JS/TS). Integrate automated tests into CI/CD, develop end-to-end, integration, and performance tests, apply AI techniques for test generation and defect detection, troubleshoot system issues, mentor QA teams, and drive automation and quality engineering best practices.

The role involves developing test automation frameworks, translating hardware specifications into tests, and collaborating with engineering teams for AI hardware validation.

The Principal Test Framework Software Engineer will design and implement test automation frameworks for hardware validation, collaborating with teams to ensure quality and efficiency in AI hardware systems.

Own test planning, exploratory and risk-based testing, and automation across sprints. Partner with product teams to define acceptance criteria, maintain test environments, contribute to regression suites, surface defects, and develop a testing specialization (automation, API, performance, security, or release coordination).

The Lead Software Test Engineer ensures quality of software platforms, develops and executes tests, sets automation standards, and collaborates with cross-organizational teams to improve testing practices.

Lead quality engineering for Accident Management by defining test strategy, writing automation-ready acceptance scenarios, designing test frameworks, improving CI/CD signals, partnering with QA automation engineers, reviewing automation PRs, and establishing release-readiness evidence across UI, APIs, and observability.

The Embedded Software Test Engineer will design test plans, implement tests for products, automate testing in CI, and communicate results with cross-functional teams.

Design and develop black-box and white-box test plans, implement pre- and post-silicon tests, automate tests in CI, triage/debug issues with software teams, and present results to stakeholders.

Build and maintain scalable integration and end-to-end test automation frameworks, optimize CI pipelines and test execution, improve test stability and reporting, support engineering teams with triage and best practices, write technical specs/ADRs, participate in on-call rotation, and collaborate cross-functionally to evolve the company test strategy.

Join a cross-functional Agile team to drive software quality for PACSystems. Design and execute system-level tests, build automated unit/integration/end-to-end tests, author testable specifications, configure test environments, isolate and document defects, and apply AI-assisted and spec-driven practices to improve test coverage and delivery.

Design, build, and maintain production-grade test infrastructure, release orchestration tooling, and performance testing systems. Drive automation strategy across unit, integration, API, and end-to-end layers, migrate test frameworks (Cypress to Playwright), add observability for flakiness and reliability, and mentor engineers while solving complex infrastructure and AI-assisted testing problems.

Lead test automation for web applications and a CDN-backed content delivery platform. Design, build, and maintain automated frameworks (UI/API), integrate CI/CD, run performance and scalability tests, validate cloud-native AWS services, and support release activities including code reviews, defect triage, and root cause analysis.

Lead QA activities for an IAM program: design and implement QA methodologies, create and run manual and automated tests, perform code/product reviews, triage defects, validate functionality/performance/security, and support CI/CD, UAT, and release validation across Agile teams.

Design, write, and execute automated tests (functional, performance, scalability, durability); build and maintain test frameworks; create integration and regression test cases; analyze failures, troubleshoot issues, measure test coverage, and collaborate with product and software engineers to improve software quality.

Develop and scale automated test systems for RF and satellite communications payloads, control lab instrumentation, build reusable frameworks and CI/CD-integrated automation, debug hardware/software integration issues, and design scalable test infrastructure to ensure repeatable system validation.

Develop and maintain automated tests and test frameworks (E2E, unit, integration, performance), integrate testing into CI/CD, collaborate with engineers and product teams to find and document defects, and improve test infrastructure and processes for PDQ products.

The Software Test Engineer will design, implement, and maintain test frameworks for back-end services, ensuring product quality through test case creation and automation, and collaborating with cross-functional teams.

As a Software Development Engineer in Test II, you'll develop automated tests for routing and switching hardware, improving test efficiency while collaborating with engineering teams.

Lead quality efforts across backend services, APIs, and customer-facing apps. Design and implement automated test frameworks, build custom tooling and load testing solutions, improve testing pipeline scalability, mentor engineers, and apply GenAI/LLMs to testing and test-generation challenges.

Develop, maintain, and execute automated and manual test plans for hardware and software platforms. Enhance automation framework and tooling, perform performance and scalability testing, analyze results, track defects, estimate test effort, and collaborate with developers in scrum teams to improve code quality.
