The Opportunity

Based in Hyderabad, join a global healthcare biopharma company and be part of a 130- year legacy of success backed by ethical integrity, forward momentum, and an inspiring mission to achieve new milestones in global healthcare.
Be part of an organisation driven by digital technology and data-backed approaches that support a diversified portfolio of prescription medicines, vaccines, and animal health products.
Drive innovation and execution excellence. Be a part of a team with passion for using data, analytics, and insights to drive decision-making, and which creates custom software, allowing us to tackle some of the world's greatest health threats.

Our Technology Centers focus on creating a space where teams can come together to deliver business solutions that save and improve lives. An integral part of our company’s IT operating model, Tech Centers are globally distributed locations where each IT division has employees to enable our digital transformation journey and drive business outcomes. These locations, in addition to the other sites, are essential to supporting our business and strategy.
A focused group of leaders in each Tech Center helps to ensure we can manage and improve each location, from investing in growth, success, and well-being of our people, to making sure colleagues from each IT division feel a sense of belonging to managing critical emergencies. And together, we must leverage the strength of our team to collaborate globally to optimize connections and share best practices across the Tech Centers.

Role Overview:
The Testing Engineer is responsible for designing and executing automated and manual tests to ensure the quality, reliability, performance, and usability of our systems and data products. This role works closely with product teams, software engineers, data engineers, and other stakeholders to understand requirements, design effective test strategies, and validate both application behavior and underlying data integrity.
The ideal candidate combines strong testing expertise with hands-on programming skills, basic knowledge of modern web development frameworks, solid data engineering skills (data models, SQL, and data validation), and practical experience with our Quality Engineering toolset.
What will you do in this role

Key Responsibilities
Test Strategy & Planning

Analyze and understand functional and non-functional requirements, technical design specifications, and data models for systems under test (applications, APIs, and data pipelines).
Design comprehensive test strategies, including test plans and test suites covering functional, integration, regression, performance, security, and data validation testing.
Define testing parameters in collaboration with product teams, developers, data engineers, and other project stakeholders.

Test Design & Execution

Design and implement test cases, test scripts, and test data for both manual and automated testing, mapping tests back to clear acceptance criteria and requirements.
Create automated test scripts to cover UI, API, backend services, and data validation tests, leveraging appropriate frameworks and tools (e.g., Tosca, Robot Framework, Selenium, LoadRunner).
Execute test suites, document results, identify defects, and track them through to resolution.
Create detailed, step-by-step documentation of test procedures to ensure replicability and compliance with internal standards and regulatory expectations.

Automation & Tools

Align with automation best practices and standards, including coding standards, test design techniques, and modularized test case development.
Develop, maintain, and optimize automated regression suites as part of CI/CD pipelines (e.g., via QE Test Hub and GitHub Actions).
Use test management tools (e.g., Xray Test Management with Vera DevOps) to plan, track, and report on testing activities and coverage.
Contribute to continuous improvement of the test automation framework, tooling, and test processes.

Data Validation, Data Quality & Integrity

Collaborate with data engineers and product teams to understand data flows, data models, and business rules.
Design and execute tests to validate data quality, data completeness, and data integrity across ETL/ELT pipelines, APIs, and downstream systems.
Write and optimize SQL queries to validate datasets, transformations, aggregations, and reports.
Identify data quality issues, perform root cause analysis, and work with engineering teams to define and validate fixes.
Contribute to the definition of data quality metrics, test data strategies, and automated data validation checks.

Collaboration & Stakeholder Management

Meet regularly with product teams to determine testing parameters and align on priorities, schedules, and acceptance criteria.
Work with cross-functional groups on project-wide efforts; demonstrate leadership in test design, product direction discussions, and quality-related decision-making.
Engage with delivery teams to confirm that products and services meet service acceptance criteria and are delivered to the required standard.
Provide input into change control processes, risk assessments, and release readiness decisions.
