Senior Quality Control Engineer (Manual & Automation Testing)

MISSION

The Senior QC Engineer is responsible for driving product quality and testing maturity across the team by owning end-to-end test strategies, building scalable automation frameworks for web, API, and mobile platforms, and mentoring junior engineers.

This role serves as a technical reference point and quality leader, ensuring that every release meets high standards of reliability, stability, and user trust. The Senior QC Engineer works closely with Developers, BA, Product Owners, and DevOps to identify quality risks early, optimize test coverage, and continuously improve QA processes for fast and confident product delivery.

KEY RESPONSIBILITIES

• Define and own comprehensive test strategies, test plans, and test approaches for complex features and cross-platform initiatives, applying risk-based analysis to prioritize scope and optimize coverage.

• Design and execute complex test scenarios across functional, integration, regression, exploratory, and UAT testing for web, API, and mobile (Flutter) applications.

• Design, build, and maintain mobile automation frameworks for Flutter applications, covering cross-device and cross-OS scenarios (iOS & Android).

• Build and maintain scalable automation frameworks for Web UI and API testing using Playwright, Postman/Newman, or equivalent, including reusable components, utilities, and libraries.

• Lead API testing strategy across microservices and distributed systems, including authentication, schema validation, contract testing, and third-party integrations.

• Integrate automated tests into CI/CD pipelines and optimize execution time through parallelization and stable test design.

• Drive defect triage, root-cause analysis, and impact assessment for production issues, and contribute to release readiness assessments and Go/No-Go decisions.

• Mentor and coach junior/middle QC engineers through code reviews, knowledge-sharing sessions, and pair testing.

• Act as a quality advocate in cross-functional discussions with Dev, BA, PO, and stakeholders, and participate in Agile/Scrum ceremonies.

• Champion adoption of ATDD/BDD/TDD practices and shift-left testing approaches; identify gaps in QA processes and implement scalable improvements.

• Support basic performance/load testing execution using tools such as K6, JMeter, or Locust when required.
