Jobbeschreibung

Our goal is to have a solar system on every roof, a storage unit in every house, and an electric car in every garage. the company makes this possible with an integrated total solution for decentralized energy—from solar systems and battery storage to wall boxes, smart meters, and heat pumps. At the heart of it all is our AI-powered platform the company.One+, which intelligently connects thousands of systems and efficiently optimizes electricity procurement and feed-in on the energy market.

the company Heat is the company's heat pump business unit. We are the market leader and install >10,000 heat pumps per year.

In 2025, more heat pumps than gas heaters were installed in Germany for the first time – the heat transition is in full swing! As the heat and heating market in Germany remains very dynamic, we must continuously develop our product range and sales strategy in the heat sector.

The role

You will be working as a Senior BI Developer who thinks like an engineer first and a dashboard builder second. You'll own the data models that power our reporting layer — designing, building, and maintaining the pipelines, tables, and semantic layer that the whole team depends on.

This is not a "connect a spreadsheet to Power BI" role. You'll be deep in Snowflake, writing production-grade SQL and dbt models, designing schemas that scale, and collaborating closely with Data Engineers to make sure the data that lands in our warehouse is clean, reliable, and ready to use.

You'll be a strategic partner to stakeholders across the Heat business, from sales leadership to fulfilment operations, shaping our BI strategy, influencing how performance is measured, and ensuring the right questions are answered with the right data.

What you’ll do

• Own the data model layer — design and maintain dbt models; powering KPI dashboards, ad-hoc analysis, and stakeholder reporting.
• Write production-grade SQL — window functions, cohort logic, SCD deduplication, and multi-join pipelines across Snowflake schemas.
• Partner with senior stakeholders — translate business questions from sales, fulfilment, and leadership into robust data models and clear insights for both technical and non-technical audiences.
• Help shape our data & BI strategy — contribute to tooling decisions, modeling standards, and KPI governance as the business scales.
• Use AI as a development partner — leverage agentic coding assistants (Claude Code, Codex) and AI-enhanced BI tools to ship faster and smarter.

What you’ll bring

• 5+ years of experience in BI development, data engineering, or a hybrid role.
• Stakeholder communication — you can translate ambiguous business questions into clear data requirements and present findings confidently to senior, non-technical audiences.
• Strong SQL, dbt & data modeling — expert-level SQL, production dbt experience (incremental models, tests, docs), and solid understanding of dimensional modeling a in a cloud data warehouse.
• BI tool experience — Power BI at a level where you can build semantic models, not just drag-and-drop visuals.
• Engineering mindset — Modular and testable code, pipelines treated with the same rigour as software.
• Hands‑on AI tooling — you actively use agentic coding assistants (Claude Code, Codex, Copilot) in your development workflow and have applied AI tools in data contexts

Nice‑to‑Have

• Experience with Snowflake as a primary cloud data warehouse.
• Familiarity with fulfilment operations data — scheduling, installation pipelines, or field operations metrics.
• Exposure to Python for data transformation or automation tasks.
• Experience working in a scale‑up or high‑growth environment where requirements change fast.
• Knowledge of German (our stakeholder outputs are often bilingual).

What we offer

• Work at Germany's first green unicorn — Play an active role in shaping the solar energy transition.
• The sun shines all over the world — At the company, you'll work with a highly motivated, diverse team of over 65 nationalities.
• The ideal setup for your focus — We are convinced that excellent results are achieved when the conditions are right. That's why we rely on a hybrid working concept that gives you the freedom to always work in the way that best suits your tasks. Do you need new inspiration on an international level? With Workflex, we offer you the opportunity to relocate abroad for up to 30 days a year, depending on your responsibilities.
• Grown‑up business & startup spirit — In our modern office in Berlin‑Friedrichshain, you'll find everything your heart desires, from height‑adjustable desks and table tennis to stocked beverage fridges and barista coffee.
• Your kick‑start at the company — Onboarding day with a welcome bag, buddy program, and a team that really supports you.
• Stay up to date & help shape the future — Transparent all‑hands meetings, short decision‑making processes, and an open feedback culture - without mistakes, there is no progress.
• The energy transition can only be achieved together — At the company, you can expect legendary team spirit and unforgettable team events.
• Your extra boost — 29 vacation days + one additional day off on Christmas Eve and New Year's Eve, discounted membership at Wellhub, and corporate benefits. Everything you need to help you achieve a good work‑life balance.
