The Role

We’re looking for a Software Development Engineer in Test (SDET) who goes
beyond writing tests - someone who delivers robust automation frameworks,
drives testing strategy, and empowers engineering teams to deliver high-quality
software at scale.

This role is ideal for someone who thrives in autonomy, influencing testing
strategy, and has a proven track record of building automation capabilities from
the ground up. You’ll spend your time primarily on automation and framework
development with some manual exploratory testing as required/while automated
frameworks sufficiently mature.

Implement robust test automation solutions following established design patterns and best practices (e.g Page Object model, fixtures, reusable modules, etc).

Collaborate closely with developers, product owners and other stakeholders to understand requirements and define test strategies.

Participate in requirements reviews, design discussions and sprint ceremonies to ensure quality considerations are addressed early in the planning process.

Analyze test results and reports, investigate failures, identify root causes and work with development teams to resolve defects.

API Testing

Design and execute comprehensive automated tests for backend services and APIs (REST/SOAP/GraphQL).

Validate API functionality, compliance to OpenAPI Specification documentation, authentication/authorization and error handling.

Integrate API testing into CI/CD pipelines (e.g GitHub Actions) to support continuous testing initiatives.

Performance & Load Testing

Develop and execute performance, load and stress tests to evaluate system reliability and scalability under various workloads.

Define realistic workload models and performance acceptance criteria based on business and technical requirements.

Analyze performance metrics, identify bottlenecks and provide actionable recommendations for optimization.

Collaborate with development and infrastructure teams to troubleshoot and improve application performance.

CI/CD – Test Infrastructure

Integrate automated tests into CI/CD pipelines (e.g GitHub Actions).

Support implementing quality gates within the deployment process to ensure rapid and reliable delivery.

Contribute to maintaining test environments, test data strategies and requirements, automation infrastructure.

Monitor and improve test execution efficiency, reliability and reporting.

Quality Advocacy

Author and maintain comprehensive test plans, strategies and detailed test cases in the company's TCMS (TestRail), based on business, functional and technical requirements.

Promote quality engineering best practices throughout the organization.

Mentor team members on automation solutions, testing strategies and quality standards.

Drive continuous improvement initiatives related to test automation, performance testing and overall software quality.

About You

4-6+ years of hands-on experience as an SDET or in QA automation, with a strong record of building frameworks and driving strategy.

Proficient in both UI and backend test automation development (Python and/or C# are strongly preferred).

Experience using Playwright for UI/browser-based test automation.

Proven experience testing various API implementations (REST, SOAP, GraphQL).

Skilled in enabling shift-left testing and developer adoption of automation practices.

Advanced knowledge of MongoDB, SQL and test data management.

Experience integrating automated tests into CI/CD pipelines (GitHub Actions, CircleCI, ArgoCD, Jenkins, etc).

Strong problem-solving, communication, and collaboration skills.

Self-starter with a strategic mindset and ownership mentality.

Bonus: ISTQB certification, performance or security testing experience.
