Software Development Engineer in Test (SDET)

Build the scalable test automation platform that powers EV charger validation, manufacturing, and product quality worldwide. At ABB E-mobility, we are accelerating the future of sustainable transportation through innovative EV charging solutions. We are looking for a Software Development Engineer in Test (SDET) to join our Operations Test Engineering team and lead the development of a shared test automation platform supporting engineering validation, system integration, and manufacturing test environments. This is a highly software-focused role where you will design, develop, and industrialize the test toolchain used across E2E test benches, hardware-in-the-loop environments, pilot lines, and end-of-line manufacturing stations. Your work will directly improve release confidence, product quality, manufacturing readiness, traceability, defect containment, and the scalability of automated testing across the entire EV charging ecosystem.

Your Responsibilities

• Design, develop, and maintain a scalable, modular, and reusable automated test framework supporting end-to-end validation, system integration, regression testing, release qualification, hardware-in-the-loop environments, and manufacturing test execution.

• Develop production-grade software for test orchestration, equipment control, measurement acquisition, diagnostics, result evaluation, reporting, recovery mechanisms, and reliable execution across validation and manufacturing environments.

• Integrate automated testing into CI/CD pipelines, enabling pull-request validation, regression execution, software-build qualification, release gates, artifact management, result publication, and controlled deployment of test software.

• Build software interfaces connecting chargers, embedded controllers, charging communication stacks, PLCs, programmable power supplies, electronic loads, instruments, thermal systems, safety devices, production fixtures, cloud services, databases, and manufacturing systems.

• Create automated tests for APIs, services, firmware interfaces, communication protocols, charging workflows, diagnostics, error handling, recovery scenarios, and complete charger-to-cloud or charger-to-manufacturing-system use cases.

• Define and maintain structured test data, logs, measurement records, pass/fail criteria, requirement traceability, software and firmware versioning, equipment configurations, calibration information, and release-evidence packages supporting quality and deployment decisions.

• Continuously improve framework reliability, maintainability, execution speed, and diagnostic capabilities by reducing flaky tests, minimizing false failures, optimizing retry logic, improving observability, and supporting evolving products and manufacturing processes.

• Develop reusable libraries, templates, configuration models, documentation, coding standards, examples, and utilities that enable software, validation, and manufacturing teams to contribute automated tests consistently and efficiently.
