Senior SDET - Tooling Engineer

Quality Engineering & Test

• Own end-to-end quality across iOS and Android applications and their supporting backend services, ensuring high confidence in weekly (or faster) releases.
• Design and implement comprehensive test strategies covering:
  • Native mobile applications (iOS & Android)
  • Mobile-to-backend integrations (REST APIs, auth flows, event-driven systems)
  • Microservices and distributed systems
  • Critical web workflows that intersect with mobile journeys
  • Device, OS, browser, and network variability
  • App lifecycle events, offline behavior, retries, and edge cases
• Ensure critical user journeys are validated across mobile UI → API → backend → web touchpoints, preventing production escapes in high-impact flows.
• Partner with engineering teams to embed quality gates into the mobile release lifecycle, including pre-merge validation, release candidate verification, and post-deploy smoke testing.
• Drive improvements in testability by introducing better logging, API contracts, observability hooks, feature flags, and deterministic state management.
• Establish meaningful quality metrics (crash analytics, defect trends, flaky tests, API reliability, release risk scoring) and surface actionable insights to engineering stakeholders.
• Champion shift-left quality by influencing design reviews, API schema discussions, and acceptance criteria early in development.

AI-Driven Quality and Automation

• Leverage AI to enhance mobile, backend, and web testing effectiveness, including:
  • AI-assisted test case and test data generation
  • Intelligent regression suite prioritization based on code changes
  • Predictive defect detection and risk-based testing
  • Flaky test detection and automated stabilization insights
• Integrate AI-powered log intelligence, crash clustering, and anomaly detection into quality workflows.
• Continuously evaluate and experiment with AI-driven QA tools to increase coverage, reduce maintenance overhead, and accelerate release cycles.
• Contribute to building an AI-augmented quality ecosystem that improves speed without compromising reliability.

Automation Excellence

• Design, build, and scale robust automation frameworks using:
  • XCUITest, Espresso, Appium (mobile automation)
  • Playwright (web and mobile web validation)
  • REST Assured or similar tools for API and service validation
• Ensure frameworks are modular, maintainable, and optimized for scale across multiple teams.
• Integrate automated validation into CI/CD pipelines (Jenkins, GitHub Actions, etc.) to enable:
  • Pre-merge quality gates
  • Parallelized execution
  • Environment-aware test runs
  • Post-deployment smoke and regression coverage
• Build developer-friendly tooling that enables:
  • Self-service test execution
  • Real-time reporting and dashboards
  • Faster debugging and failure triage
  • Scalable test data and environment management
• Continuously reduce flakiness, improve signal quality, and optimize execution time across mobile and backend suites.

Performance, Scalability & Reliability

• Design and execute performance validation across:
  • Mobile app startup time and responsiveness
  • API latency, throughput, and reliability
  • Backend load and stress conditions
  • Web performance for critical flows
• Partner with engineering teams to analyze production logs, crash reports, browser telemetry, and service metrics.
• Lead root-cause analysis of complex cross-layer defects spanning mobile UI, APIs, backend services, and web surfaces.
• Ensure reliability validation is embedded directly into release workflows.

Cross-Functional Collaboration and Leadership

• Collaborate closely with mobile engineers, backend developers, web engineers, product managers, DevOps teams, and release managers to define clear, testable requirements and release criteria.
• Actively participate in sprint grooming, planning, stand-ups, and retrospectives.
• Influence best practices around mobile-first design, API contracts, and release readiness.
• Support mobile app release activities, including release candidate validation, go/no-go recommendations, and post-release monitoring.
• Mentor junior QA engineers and contribute to raising the technical bar in automation and cross-platform validation.
• Work effectively with globally distributed teams to coordinate testing across time zones.

What We're Looking For

• 4+ years of experience in web and mobile testing, with a strong emphasis on test automation.
• Proven expertise in designing and maintaining scalable test automation frameworks.
• Hands-on experience with mobile testing frameworks such as XCUITest (iOS) and Espresso (Android), and web frameworks like Playwright.
• Strong understanding of testing across microservices, APIs, and distributed systems.
• Ability to analyze and debug complex test failures, automation issues, and defects efficiently.
• Familiarity with generative AI applications in quality engineering (test case generation, API contract validation, log intelligence, etc.).
• Passion for leveraging AI to reduce manual effort, increase coverage, and accelerate release cycles.
• Proven experience supporting weekly release cycles with a mix of manual and automated regression testing.
• Strong analytical, debugging, and problem-solving skills.
• Experience using or implementing AI/ML-powered testing tools is a significant plus.
• Experience collaborating with global teams across multiple time zones.
• BS in Computer Science, Computer Engineering, or equivalent professional experience.

Nice to Have

• Experience supporting mobile app store release processes (App Store / Play Store), release candidate validation, phased rollouts, and post-release monitoring.
• Familiarity with crash reporting tools, release health dashboards, and rollback strategies.

Compensation: Base salary range $210,000 to $257,000, plus equity and benefits. Excellent benefits including healthcare, internet/cell phone reimbursement, and learning and development stipend.
