About The Position

We are seeking a highly skilled and motivated Senior Quality Assurance Engineer to lead our quality initiatives and ensure the delivery of high-performing, reliable software. As a key member of our engineering team, you will not only design and execute complex testing strategies but also act as a mentor, process advocate, and architectural advisor. You will be instrumental in evolving our automated testing frameworks and fostering a "quality-first" culture across the entire development lifecycle.

Requirements

Proficiency in at least one object-oriented language (e.g., Python, JavaScript/TypeScript) to build and maintain complex automation frameworks.
Expertise in industry-standard tools. Experience developing automated tests for Windows based applications is highly preferred.
Web: Selenium, Playwright, or FlaUI.
API: Postman, REST Assured, or PyTest.
Practical experience with CI/CD pipelines (e.g., Jenkins, GitHub Actions, GitLab CI).
Familiarity with cloud platforms (AWS, Azure, or GCP) and containerization (Docker, Kubernetes) to simulate production-like testing environments.
Experience defining and tracking KPIs such as Mean Time to Detect (MTTD), Mean Time to Resolve (MTTR), and defect leakage rates to demonstrate the ROI of the QA team.
Strong background working in iterative environments, including participation in sprint planning, grooming, and retrospectives.
Experience with SCADA (Supervisory Control and Data Acquisition) application and PLC devices REQUIRED.
Bachelor’s degree in computer science or in “STEM” Majors (Science, Technology, Engineering and Math)
A minimum of 6 years of professional experience

Responsibilities

Designing comprehensive test strategies for complex features, ensuring full coverage across unit, integration, system, and regression testing.
Designing and maintaining robust automation frameworks from scratch, selecting the right tools (e.g., Playwright, FlaUI, Protractor, RestAssured, Selenium, Playwright etc) that align with the company’s tech stack.
Working on the DevOps tasks to integrate automated testing into the Continuous Integration/Continuous Deployment pipelines to ensure "quality at speed."
Upkeep of all the test environments (on premise and cloud). Managing the security patching on the test deployments.
Performing deep-dive risk assessments to identify which parts of the application are most prone to failure and prioritizing testing efforts accordingly.
Moving beyond functional testing to oversee or perform non-functional testing, including load testing, stress testing, and basic security vulnerability assessment.
Investigating complex production issues to understand why bugs escaped the testing cycle and implementing safeguards to prevent recurrence.
Coaching junior engineers on best practices, code quality, and testing methodologies.
Identifying bottlenecks in the software development lifecycle (SDLC) and proposing process improvements (such as shifting left - testing earlier in the development cycle).
Acting as a "Quality Champion" within the organization, promoting a culture where quality is a shared responsibility among developers, product managers, and designers.
Participating in design and architecture meetings early in the process to identify logical flaws or edge cases before code is even written.
Translating technical quality metrics (e.g., defect density, test coverage, pass/fail rates) into actionable insights for product managers and stakeholders.
