LeadDataPlatformEngineer

This role is part of our INFOnline team, one of our exciting brands at saas.group. INFOnline powers digital audience measurement for the German and Austrian media industry. Our systems process billions of events and deliver the trusted reach and engagement metrics used by publishers, advertisers, agencies, IVW and OEWA. As part of saas.group, we have been modernizing our business-critical infrastructure and moving towards a fully cloud-native architecture on GCP. The major migration work is complete. Now we are looking for a strong technical owner to run, harden, scale and evolve the new platform. Profile Overview We’re looking for a technically deep, hands-on Lead Data Platform Engineer to take full ownership of INFOnline’s central data platform from raw event ingress through processing, aggregation, data modeling and reporting delivery. You will take ownership of a newly built GCP-native data platform as it moves from completed migration into long-term production operation, optimization and continuous evolution. This is not a role where you simply follow someone else’s roadmap. You will help define how the platform should mature: where we need stronger observability, better data quality controls, clearer ownership boundaries, improved documentation, cost efficiency and more scalable operating models. This is a hands-on technical leadership role. You will set technical direction, make architecture decisions, establish engineering standards, mentor others and still work close to the code and systems. On top of that, you will help drive AI-native engineering practices using coding agents, AI-assisted testing, documentation, refactoring and incident analysis to increase engineering speed and quality. Your immediate impact in the first 3-6 months will be: Audit and map the existing cloud and data platform architecture identify critical risks, dependencies, and improvement opportunities Take ownership of core platform components from data ingress to reporting, supported
