Senior Test Design Engineer

Collaborate with software engineers on the design and development of software solutions, contributing to architectural decisions and the implementation of scalable, maintainable, and reliable systems that support long-term product strategy.

Work closely with test engineers to standardise and optimise validation methodologies, automate processes, and consolidate test sequences across multiple product lines.

Improve the quality, consistency, and structure of engineering and test data to enable AI-driven analysis, improved fault diagnosis, increased automation, and reduced product test times.

Contribute to software engineering best practices, including architecture reviews, code reviews, automated testing, and continuous integration.

Lead or contribute to the development of advanced software applications, tools, and services that enhance engineering productivity and product quality.

Take technical ownership of server-based systems and services supporting the validation environment, including responsibility for database architecture, data management, data synchronisation, data integrity, and associated infrastructure.

Develop, maintain, and support solutions for network configuration, data synchronisation, database operations, web services, and other engineering platforms.

Provide technical leadership and guidance on software design, architecture, and engineering best practices, working collaboratively with engineers across multiple disciplines and sites.

Support the investigation and resolution of issues within manufacturing and test environments, including occasional involvement in the diagnosis of test system hardware failures.

Knowledge, skills and experience required

Extensive professional experience in software engineering, including the design, development, and delivery of complex software systems.

Demonstrated experience defining software architectures, evaluating technical solutions, and making design decisions that support long-term business and engineering goals.

Strong technical expertise with the ability to independently design and implement software architectures, frameworks, web services, data models, and database solutions.

Experience developing and supporting software solutions that utilise relational databases and data-driven architectures.

Experience developing and supporting software solutions within both Windows- and Linux-based environments.

Proficiency in object-oriented software development using Python and C++, with strong debugging, troubleshooting, and problem-solving skills.

Experience with modern software development practices and tools, including version control systems such as Git and Subversion.

Experience developing software solutions for automated test, measurement, or validation environments, with an understanding of the challenges associated with large-scale test systems.

Experience working collaboratively with stakeholders to develop test frameworks, infrastructure, automation, and data-driven engineering processes.

Strong communication, collaboration, and technical leadership skills, with the ability to influence architectural decisions.

Desirable Skills and Experience

Strong experience with relational database technologies, including database design, SQL development, data modelling, performance optimisation, and large-scale data management.

Experience designing and maintaining scalable server-based applications and services within Linux environments.

Experience with web services, distributed systems, networked applications, and data synchronisation technologies.

Knowledge of networking and communications technologies, including Ethernet, TCP/IP, switching, routing, and distributed systems concepts.

Practical hardware debugging skills, including experience using diagnostic equipment such as multimeters, oscilloscopes, and network traffic analysers to support investigation of issues within development and manufacturing environments. While not a primary focus of the role, the ability to assist with hardware fault diagnosis and test system troubleshooting would be advantageous.
