Software Development Engineer in Test (SDET) - WirelessCar

We are looking for a Software Development Engineer in Test for our client WirelessCar. About the role WirelessCar develops and operates connected vehicle services for automotive customers around the world. Within Assistance Services, our products support customer journeys such as emergency call, assistance and stolen vehicle tracking—services where quality, availability and reliability matter every day. Your primary responsibility is to design, develop and maintain automated end-to-end validation for complete customer journeys. You will turn customer and system behaviour into executable test cases across APIs, backend services, customer integrations and graphical clients. You will use the Internal Developer Platform (IDP) for test, CI/CD, environment and observability capabilities, give feedback when customer needs reveal gaps and help improve them when appropriate. This is technical software development focused on automation and evidence, not manual test execution. This work is where quality engineering becomes visible to customers and teams. What you’ll focus on Translate customer and system behaviour into clear requirements, acceptance criteria and automated end-to-end test cases for complete customer journeys. Design, code and maintain automated validation for complete customer journeys. Validate customer journeys across APIs, backend services, distributed services, customer integrations and graphical clients. Use the IDP’s test, CI/CD, environment and observability capabilities to make journey validation repeatable. Provide the IDP team with concrete requirements and feedback when tooling, environments, test data, simulators or softcars are missing, and help improve those capabilities when appropriate. Integrate end-to-end validation into CI/CD workflows so teams receive fast feedback. Use metrics, logs, traces, monitoring and alerting to understand customer-journey and service health. Contribute to incident investigation and recovery, feeding production learning back into automated tests, reliability and system improvements with sound AI-assisted engineering judgement. What you bring You are fundamentally a software developer who enjoys solving customer problems through code, automation, automated end-to-end test cases and investigation. You may currently work as an SDET, Software Engineer, Quality Engineer, Test Automation Engineer or SRE. The title matters less than your ability to build useful software and establish confidence in complex systems. You understand that reliable automation is software: it needs clear design, readable code, useful failure messages, maintainable test data and environments, and feedback that engineers can act on. You are comfortable learning the domain, exploring unfamiliar systems and working with customers and colleagues to understand what must be proved. Experience developing software and automated end-to-end test cases with modern programming languages and frameworks, and using AI-assisted development tools responsibly to accelerate implementation, test creation and investigation while validating the results. Experience developing automated test cases and validating behaviour beyond an individual service or API. Practical experience with CI/CD, cloud environments, distributed systems and production-like integration scenarios. Ability to use observability data, including logs, metrics and traces, to debug failures and understand system health. Comfort moving between requirements, source code, pipelines, customer discussions and production incidents. Understanding of proportionate validation, maintainable automation and clear technical evidence. Ownership, constructive communication and a willingness to collaborate across customer and IDP teams. Nice to have Experience consuming or contributing to Internal Developer Platform capabilities. Experience with customer integrations, simulators, softcars or service virtualisation. Experience with SRE practices, performance testing, resilience engineering or high-availability services. Experience from automotive, connected-vehicle or other business-critical domains. The teammate we’re looking for You take ownership of real customer outcomes and use evidence to establish confidence. You ask good questions when requirements are unclear, challenge assumptions constructively and turn uncertainty into something the team can test or observe. You enjoy collaborating across customer and platform boundaries, share knowledge freely and help others succeed. You bring a practical, curious and positive attitude, use “we” more often than “I”, and believe strong engineering should leave room to have fun. You are comfortable working where the answer is not immediately known. You listen to customer context, make technical trade-offs visible and help the team move from a failing example to a durable improvement. You share what you learn with both the customer team and IDP colleagues. What success looks like Automated end-to-end validation becomes the default confidence check for complete customer journeys across services, integrations and graphical clients. Engineering teams receive faster feedback and can deploy with greater confidence. Production behaviour and incidents continuously improve requirements, automated tests and observability. Customer integrations become faster, services become more resilient and recurring incidents decrease. If you want to write software that solves real customer problems and makes connected mobility more dependable, we would love to hear from you. You will see the results in faster feedback, clearer decisions and more dependable customer outcomes. We offer continuously. That means that we sometimes remove the assignments before deadline. If you are interested we recommend that you apply immediately. PayExpress: We now offer a fast and smooth payment solution, so you don't have to wait through long payment periods.
