Lead Data Platform Engineer

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.

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.

• 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 by structured knowledge transfer where needed 
• Establish full internal ownership of the new cloud-native data platform 
• Improve data quality controls, validation processes and operational safeguards 
• Build a pragmatic post-migration roadmap focused on stability, scalability, data quality, cost efficiency and business continuity 
• Strengthen monitoring, alerting, and observability for business-critical data workflows and IVW/OEWA delivery pipelines
• Establish engineering standards around documentation, code reviews, testing and AI-native development practices 

• Own the end-to-end data platform roadmap and drive its execution from architecture decisions to day-to-day platform operations
• Take accountability for data ingress, streaming processing, batch aggregation, data modeling, quality, delivery and reporting logic
• Ensure reliability, scalability and performance through strong monitoring, observability and incident management practices
• Continuously improve the new GCP-native platform with a focus on stability, cost efficiency, maintainability and business continuity
• Collaborate closely with Product, Customer Success and Leadership to translate business requirements into scalable technical solutions
• Drive AI-native engineering adoption, including AI-assisted coding, refactoring, testing, documentation and code reviews and establish standards for safe, effective use
• Work with external specialists where useful and establish sustainable internal ownership of all critical platform components

• 5+ years of experience in Data Engineering, Data Platform Engineering, or Platform Engineering in production environments
• Solid Go (Golang) proficiency is required. Our core backend systems, including ingress collectors, Pub/Sub processors, Dataflow jobs, batch loaders, controllers and CLI tools are written in Go. 
• Strong hands-on experience with GCP Cloud Run, Pub/Sub, BigQuery, Dataflow, Cloud Storage, Cloud SQL
• Strong SQL and analytical data modeling skills; familiarity with SQLMesh (or similar dbt-style orchestration tools) is a significant plus
• Practical experience with Terraform / IaC, CI/CD pipelines, and containerized workloads (Docker; Cloud Run-style serverless, not cluster Kubernetes)
• Experience with Protobuf or comparable schema definition and serialization frameworks
• Familiarity with IVW, OEWA or comparable digital audience measurement standards or a genuine interest in the web analytics domain and the ability to ramp quickly 
• Experience with AI coding assistants and coding agents (Claude Code, Codex, or similar) and sound judgment in reviewing AI-generated code for quality, security, and operational risk
• Excellent communication skills with both technical and non-technical stakeholders
• Fluent German (C1) required; good English for technical documentation and saas.group collaboration

• Ultimate flexibility: We’re 100% remote. You can work from wherever you like, whenever you like.
• Freedom and autonomy: We’re a high-trust team, and you’ll be given lots of flexibility to solve problems in your own way, with plenty of help from the team when you need it.
• Minimum bureaucracy: We don’t like to get bogged down with meetings and red tape. We like to be efficient and keep momentum steady & sustainable.
• Small & friendly team: We help each other out, have fun, and joke around.
• Our network: We are a community of entrepreneurial SaaS professionals that regularly exchange ideas, knowledge, learning and expertise with each other internally. 

INFOnline is part of saas.group and we have a shared goal of succeeding together.
