Ground every answer in facts on this page and the original listing. We never invent Glassdoor-style reviews or salaries that are not in our data.
Strong fit if you want junior data-platform engineering at a young (2021) clean-energy scale-up with Berlin base and remote option, and you’re motivated by real energy-system data rather than generic SaaS only.
As a Junior Data Engineer on the Data Platform team at 1KOMMA5° (Berlin, remote-friendly), expect work that supports pipelines and platform services behind home energy and virtual-power-plant data: ingesting device and market signals, keeping tables reliable, and shipping small ETL/ELT or warehouse changes with senior engineers. Days likely mix ticket work, data quality checks, and docs for a fast-growing clean-energy stack.
Build foundations for junior platform work: SQL, Python, basic cloud data services, version control, and testing of pipelines. No specific certification list was provided for this role family.
The listing marks remote as available; base location is Berlin.
It works in home clean energy and operates a virtual power plant reported at ~1 GW shiftable load, with major home-energy financing news in trade press.
Platform and pipeline reliability supporting energy and flexibility data, under senior guidance—not inventing product strategy from day one.
