Senior Test Engineer

About ISSART

ISS Art is a software engineering company of 500+ delivered projects, working across manufacturing, construction, media, education, and IT. The team specialises in machine learning, computer vision, data science, IoT, and NLP — tackling technically demanding problems where craft and precision matter. Quality is treated as a shared engineering responsibility, built into the process rather than bolted on at the end.

The role

This is a newly created Senior Test Engineer position embedded within a development squad in Madrid, owning automated test strategy and execution across ISS Art's full technology stack. As the

team and project portfolio scale, this role exists to close coverage gaps systematically and raise the

quality baseline — not to run checkbox QA at the tail end of a cycle. Within the first 30 days, you'll conduct a structured audit of existing coverage gaps and deliver a prioritised testing roadmap for your squad. The project is a CRM system which helps manufacturing companies to work with their customers.

What you'll do

Design, build, and maintain automated test suites using TypeScript and Playwright across the full technology stack Conduct a structured audit of existing test coverage within the first 30 days and deliver a prioritised testing roadmap Collaborate day-to-day with developers to embed quality practices throughout the build cycle, not just at review Identify coverage gaps proactively and define test strategies before specifications are finalised Establish and enforce test standards, frameworks, and patterns that the squad can adopt and extend Triage, investigate, and document defects with enough context for developers to act without back-and-forth Contribute to sprint planning and technical discussions as the quality voice within the squad Track and report on test coverage metrics, surfacing trends and risks to the team in a timely way

What we're looking for

5–10 years of professional experience in software testing and quality engineering Experience in testing CRM or similar systems.

Production-level proficiency in TypeScript — writing and maintaining test code, not just reading it Hands-on experience building and scaling automated test suites with Playwright

Demonstrated ability to design test strategy from the ground up, including gap analysis and coverage planning Experience working embedded within development squads rather than a siloed QA team Strong written and spoken English sufficient for technical collaboration with an international team Based in or able to work from Madrid ISTQB certification of advanced or expert level.

Nice to have

API testing experience using Postman or a comparable tool
