Job Title: Senior QA Engineer

Department: Quality Assurance

Location: Mumbai (on-site, Monday to Friday Work From Office)

Experience: 4+ years

About the Role:

We are looking for an experienced Senior QA Engineer to own end-to-end quality for one or more of our product areas spanning mobile apps, embedded device firmware, and cloud services. You will drive test strategy, lead release sign-offs, build and extend test automation, and mentor junior testers. This role suits someone who is equally comfortable doing deep exploratory testing on a physical device and writing automation code that runs in CI.

Key Responsibilities:

Own the test strategy, test planning, and release quality for an assigned product area, from requirement review through production sign-off.
Review PRDs and technical designs early, identify gaps, edge cases, and risks, and influence the team toward testable, robust designs.
Design, execute, and maintain comprehensive functional, regression, integration, performance, and compatibility test suites across Android/iOS apps, device firmware, and backend APIs.
Build and maintain automated test suites (mobile UI, API, and device-level) and integrate them into the CI/CD pipeline; drive automation coverage targets for your area.
Lead root-cause analysis of complex, intermittent, and hardware–software interaction issues (connectivity, OTA, audio/video, sensor behaviour, app–device sync) using logs, device tools, and debugging utilities.
Define and track quality metrics (defect leakage, test coverage, automation pass rate, release readiness) and present release quality status to engineering and product stakeholders.
Act as the QA point of contact for developers, product managers, and support teams for your area; triage production escalations and drive them to closure.
Mentor and review the work of junior testers, establish best practices for test case design and bug reporting, and contribute to the team's QA process and tooling improvements.
Contribute to release planning, risk assessments, and go/no-go decisions.

Required Skills and Qualifications:

Bachelor's degree in Computer Science, IT, Electronics, or a related field.
4 + years of hands-on QA experience, with at least 2 years testing mobile applications and/or hardware or IoT products.
Strong command of testing fundamentals: test design techniques, risk-based testing, regression strategy, and defect life-cycle management.
Proven experience with test automation: at least one of Appium, Selenium, or Playwright, plus strong scripting skills in Python or Java.
Solid API testing experience (Postman, REST Assured, or Pytest with requests) and a working understanding of REST, JSON, authentication, and backend data flows.
Hands-on familiarity with Android/iOS debugging tools (adb, logcat, Xcode Instruments, Charles/Proxyman) and with testing across device fragmentation and OS versions.
Experience integrating automated tests into CI/CD (Jenkins, GitHub Actions, GitLab CI, or similar) and using Git.
Working knowledge of SQL and Linux command line.
Strong analytical and problem-solving skills, clear written and verbal communication, and the ability to work independently and drive outcomes with cross-functional teams.
Experience testing embedded/IoT devices, robotics, or consumer electronics, including firmware, OTA updates, BLE/Wi-Fi provisioning, and audio/video pipelines.

Good to Have:

Familiarity with testing AI/ML-driven features such as speech recognition, conversational responses, or vision-based interactions, including non-deterministic output validation.
Understanding of child-safety, privacy, and compliance requirements (COPPA, GDPR-K) for products designed for children.
ISTQB Foundation or equivalent certification.

What We Offer:

Ownership of quality for AI-powered products used by children and families worldwide.
A senior seat in a small, high-impact QA team with direct influence on product and engineering decisions.
Opportunity to shape the automation roadmap and grow into an architect track.
