Job description

For an international company operating in the industrial IoT and connected devices sector, we are looking for a Senior Testing Coordinator to lead cross-team testing activities within a complex digital transformation and platform integration program.

• Determine which tests should be manual or automated and where they should be executed.
• Establish clear processes for test execution, triage and defect resolution.
• Create and maintain an integrated test calendar aligned with releases and dependencies.
• Establish a clear E2E scenario catalogue, prioritized according to business risk.
• Define test entry/exit criteria and Definition of Ready/Done for testing.

• Establish an effective device test lab and Hardware-in-the-Loop approach.
• Determine what should be tested on real hardware, simulated or virtualized.
• Assess simulator coverage and identify gaps requiring physical devices.
• Reduce dependencies on production data for testing critical business scenarios.
• Create clear runbooks so that complex device and commissioning scenarios can be executed by non-specialists.

Migration & Data Validation

• Define backward-compatibility testing approaches during platform and domain migrations.
• Establish dual-source validation strategies for legacy and target platforms.
• Validate data consistency during migration and transition phases.
• Ensure testing timelines, dependencies and risks are clearly documented and communicated.

Testing Maturity & Knowledge Transfer

• Coach Test Engineers and Tech Leads to improve testing maturity.
• Introduce practical improvements directly within the teams’ environments.
• Encourage the adoption of relevant AI tools to improve testing efficiency and quality.
• Define and report testing KPIs and metrics.
• Establish a baseline and track progress throughout the assignment.
• Prepare a structured handover and continuation plan for internal teams.
