Our expertise spans 21 global offices, seven manufacturing sites and five R&D centres, with a global network of 3,000 dedicated colleagues contributing towards over 40 years at the frontline of advances in safety and security.

This results in careers built on variety and the opportunity to work on a range of state-of-the-art solutions, where you can develop your knowledge and experience every day.

Duties:

• Design and develop detailed test plans, procedures, scenarios, and scripts to thoroughly evaluate new products or software updates, ensuring they meet customer requirements and company quality standards.
• Develop comprehensive testing protocols and automation for various areas, including non-functional testing areas such as load,stress, performance and scalability, customer usability, database impact, error detection, regression testing, and real-world implementation scenarios. This includes understanding how software changes may affect the underlying database, ensuring that functionality is not compromised, and that system performance is optimized across all layers.
• Identify and analyze software defects, bugs, functionality issues, and output errors, documenting them in detail and collaborating with developers to resolve issues. Special attention is given to how updates might affect data flow, storage, and retrieval, potentially influencing database performance or integrity.
• Track and document issues, resolutions, and bug fixes throughout the testing process, maintaining a detailed database of defects and successful mitigation strategies, ensuring that potential database-related issues are closely monitored and addressed.
• Create clear and thorough documentation of test procedures for each phase or project to ensure replicability, compliance with standards, and growth of the company’s knowledge base, while also factoring in how changes may impact database interactions.
• Communicate effectively with cross-functional teams—including developers, product owners, and clients—to ensure quick resolution of issues, with particular awareness of potential database-related impacts and their broader implications on the system.
• Provide regular feedback to developers, offering suggestions for improvements, evaluating issues, proposing solutions, and identifying further testing needs, while considering how software changes could indirectly affect database operations.
• Implement and maintain automated testing tools as needed, ensuring they are updated and aligned with current testing requirements, including any necessary updates to address database impact in automated test cases.

Planning and Decision Making:

This role involves the individual in actively participating in the estimation and planning of deliverables for both existing and new customers, working closely with Project/Program Managers, Product Owners, and Architects. The individual will contribute to decision-making processes aimed at ensuring a 100% "say-do" ratio by helping to plan and coordinate tasks with the team. While their work will be monitored for accuracy and alignment with project goals, any issues in planning or execution could lead to delays, quality concerns, or unmet client expectations, so attention to detail and accountability are crucial throughout the process.

Impact and Scope:

This role plays a key part in the Load Testing for various programs and customer requirements for the software products. As a senior role within the team, the scope covers all requests from different airports and implementations. The individual in this role will collaborate to ensure the successful delivery of these projects, with their contributions closely monitored by the test engineering manager, for efficiency and accuracy. The individual will create test artefacts which can provide the information on the short comings and the limitations of the software for a given implementation and find the defects which should be prevented before its deployed at the customer end.

While errors in planning or execution could lead to delays, misalignment with strategic goals, or disruptions to the roadmap, the role emphasizes the importance of attention to detail and accountability throughout the process.

Key Internal and External Relationships:

Given the limited direct customer interactions, the individual will primarily work with Project Managers, Program Managers, and Product Owners on a regular basis. Building strong relationships with these internal teams will be crucial to foster better collaboration and ensure seamless teamwork.

Skills and Experience:

• A Bachelor’s degree in Computer Engineering, Computer ScienceElectrical/Electronics Engineering, Computer Engineering, or a related field, or equivalent experience.
• Preferably has experience working with systems and machines, software development, or comes from a systems software background. Experience with kernel space or driver software development is highly desirable.
• At least 5 years of hands-on experience as a software test engineer.
• Strong knowledge of object-oriented design, microservices architecture, system architecture, operating system fundamentals, networking and the ability to understand and work with software code.
• Solid understanding of the Software Development Life Cycle (SDLC).
• Extensive experience in developing Test Plans, Test Cases, and Test Reports.
• Strong proficiency in various testing methodologies.
• Proficiency in automated testing, including the creation and maintenance of automated test environments, with a preference for experience in simulated test environments.
• Expertise in Python, Linux, CI/CD tools and Conatine technologies (such as Docker etc)
• Hands-on experience with testing REST APIs.
• Good knowledge of SQL and No-SQL databases.
• Familiarity with Agile methodologies, DevOps, and continuous testing environments.
• Ability to handle multiple projects simultaneously while maintaining high standards of quality.
• Quick to adapt and learn complex systems and new technologies.
• Familiarity with open-source toolchains and technologies.
• Excellent written and verbal communication skills, with the ability to convey technical concepts clearly.
