Software QA Engineer – GIS Applications

GEOSYSTEMS HELLAS S.A., a Geoinformatics company based in Pangrati (Athens), is seeking a Software QA Engineer to join our dynamic team.

About Geosystems Hellas

GEOSYSTEMS HELLAS S.A. is a top-tier provider of advanced Earth Observation technologies, downstream space application solutions, geospatial intelligence and AI.

About the team

At GEOSYSTEMS HELLAS S.A., we foster a collaborative and innovative work environment that encourages personal growth and professional development. Join our team and contribute to cutting-edge projects with a positive impact on Earth Observation, Environmental Monitoring, Cultural Heritage, Urban Planning, Agriculture and other fields.

About the role

We are looking for a detail-oriented Software QA Engineer to help us introduce a more structured and consistent approach to software testing across our projects. As our first dedicated QA professional, the successful candidate will have the opportunity to shape our quality-assurance processes, recommend suitable tools and establish practical testing standards in close cooperation with developers, project managers and domain experts.

The initial focus will be on manual testing, including the definition, execution and documentation of business-rule, functional, integration, regression, usability and performance tests. Over time, the role may expand into automated UI, API and regression testing and the integration of automated tests into our future CI/CD pipelines.

Our applications are primarily browser-based and are mainly developed using Python, JavaScript, React, PostgreSQL/PostGIS and Mapbox, although our technology stack is not limited to these technologies.

Many of our solutions are GIS-based and developed within national and European projects. The role will therefore include testing spatial data, map-based functionality and complex user workflows. Test plans, test cases and test results may also form part of formal project deliverables, making clear documentation and technical writing important aspects of the position. Previous GIS experience is an advantage but is not required.
