Software Quality Engineer

Role Overview

Mandatory- 90% English level A Quality Engineer (QE) focusing on microservices develops and maintains test automation frameworks for distributed systems. They are responsible for testing API integrations, contract testing, and implementing shift-left testing — ensuring that independent services communicate reliably, scale seamlessly, and maintain data integrity across the entire application stack.

Key Responsibilities

Framework Development

Design, build, and maintain scalable test automation frameworks for UI, API, and backend validations using modern languages (C#, Java, Python, or TypeScript).

Microservices & API Testing

Validate RESTful APIs, service virtualization, and integration testing across distributed services.

CI/CD Integration

Integrate automated test suites into continuous integration and deployment pipelines to enable continuous quality gates before production deployments.

Performance & Scalability

Conduct load, stress, and endurance testing to evaluate system behaviour and bottlenecks under peak operational conditions.

Data Validation

Execute backend database testing (SQL and NoSQL, postgres) to ensure data integrity and proper state transitions across interconnected services.

Observability & Monitoring

Analyze system logs, metrics, and distributed tracing to troubleshoot failures and monitor microservice health.

Typical Day-to-Day

Review user stories and write test plans before development starts.

Build and maintain automated regression suites in CI/CD pipelines.

Validate REST API behavior using tools like Postman, RestSharp, or custom scripts.

Perform SQL queries to verify backend data state.

Collaborate with developers on Kubernetes-deployed services in staging/dev environments.

Report defects with clear reproduction steps and environment context.

Required Qualifications

Education & Experience

Bachelor's degree in Computer Science, Engineering, or equivalent





3–5 years of relevant experience in software quality engineering

Programming Skills and working in Microservices enviroments

Strong proficiency or preferred: C#,,Playwright ,TypeScript, — sufficient to write production-grade automation code. DevOps / Cloud Docker, Kubernetes, GitHub Actions Monitor tools, Like Dynatrace or similar

Source Control & DevOps Azure DevOps, Git, NPM

Architecture Familiarity

Experience developing or maintaining automated tests for web applications, APIs, services, or platform components under microservices / distributed systems architecture.

Experience testing Microservice APIs deployed on Kubernetes, including validation of Pod lifecycle, service endpoints, health probes, and end-to-end API behavior across distributed services

Tools & Technologies

Category Tools

API / Contract Testing Postman, REST Assured, Pact, WireMock

UI Automation Playwright, Cypress, Selenium

Performance Testing Apache JMeter, k6

Additional Experience

Familiarity with AI-assisted SDLC from a testing perspective

Experience with automated UI, API, integration, performance, or regression testing frameworks

Experience with CI/CD pipelines, Azure DevOps, and quality gates

Knowledge of security testing concepts — authentication, authorization, roles, and permissions

Experience improving test strategy, release readiness, developer tooling, or quality processes

DevOps & Version Control

Tool Usage

Azure DevOps Pipeline management, test reporting, work tracking

Git Version control, branching strategies, PR workflows

What a Strong Candidate Looks Like

Writes automated tests (unit, integration, E2E) as a first-class activity, not an afterthought

Can read and contribute to production code — not just test scripts

Understands API contracts and validates behavior at the service boundary

Thinks in terms of test coverage across layers — DB → API → UI

Champions shift-left testing — quality starts at requirements, not after development

Comfortable working across cloud-native, containerized environments
