Our partner is looking for a Senior Software Engineer, Backend - Data Streaming based in Germany. This is a foundational backend engineering role focused on building a new data streaming architecture from the ground up. You will help create a durable, continuously written streaming layer that separates data consumption from a live process execution engine. The role combines distributed systems, event streaming, cloud storage, and large-scale data architecture. You will shape core architectural decisions around consistency, durability, scalability, and reliable data delivery. Working within a small, high-ownership team, you will have significant influence over both the technology and the evolution of the team's scope. You will also collaborate closely with Product, Data Layer, Distributed Systems, QA, Support, and SRE teams in a remote-first environment. This is an opportunity to work on greenfield infrastructure with direct impact on how customers access and use process data at scale. Accountabilities * Design and build the core streaming infrastructure that decouples process data access from the live execution engine, using durable and cost-efficient storage. * Develop customer-facing data streaming capabilities that enable reliable integration with platforms such as Kafka and allow customers to consume process data within their own systems. * Help redesign how analytics products consume and serve process data at scale, moving data access away from the engine's critical path. * Make foundational architectural decisions within a small, high-ownership team, particularly around consistency, durability, distributed streaming pipelines, and data reliability. * Lead medium-to-large engineering initiatives from solution design and planning through cross-team coordination and predictable delivery. * Work closely with Product to translate requirements into actionable technical solutions and help shape the evolution of the data streaming architecture. * Collaborate with Data Layer, Distributed Systems, QA, Support, and SRE teams to deliver reliable and scalable solutions. * Participate in L3 support and on-call rotations, investigating production issues in the data layer and incorporating operational learnings into future product improvements. * Contribute to clear engineering practices through code reviews, technical discussions, direct feedback, and collaborative problem-solving. ## Related Videos - [Why and when should we consider Stream Processing frameworks in our solutions](https://www.wearedevelopers.com/videos/1085-why-and-when-should-we-consider-stream-processing-frameworks-in-our-solutions) - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [Parquet, Delta, Iceberg & Ducklake - An introduction for developers](https://www.wearedevelopers.com/videos/100075-parquet-delta-iceberg-ducklake-an-introduction-for-developers) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Tracking vehicles at scale](https://www.wearedevelopers.com/videos/1999-tracking-vehicles-at-scale) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) ## Related Articles - [Backend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/196-backend-developer-salary-in-germany-2023) - [The Biggest German Tech Companies](https://www.wearedevelopers.com/magazine/424-the-biggest-german-tech-companies) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [How Much FAANG Companies Actually Pay Software Engineers in 2025](https://www.wearedevelopers.com/magazine/230-how-much-faang-companies-actually-pay-software-engineers-in-2025) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs)
