Role
Who you are
- We are looking for someone who loves both data and people, someone who can dive deep into pipelines and systems but is equally comfortable explaining complex concepts to stakeholders.
- You are proactive, thoughtful, and passionate about building solutions that matter
- Degree in Computer Science, Data Engineering, or a related technical field (BSc or MSc)
- Solid professional experience with:
- Python (for building data pipelines)
- SQLMesh (or equivalent transformation tools)
- Google Cloud Platform (especially Cloud Run, Pub/Sub, BigQuery)
- Looker (or similar BI tools)
- Proven track record designing, building and maintaining scalable end-to-end data pipelines that ingest data from external APIs and enable efficient, accessible storage and retrieval for both internal services and stakeholders
- Experience working with energy data is a strong plus
- Confident working in CI/CD environments (e.g., GitLab CI, GitHub Actions)
- Proficient with Docker and Kubernetes
- Strong communication skills: you're able to explain data intricacies clearly and collaborate with both technical and non-technical colleagues
- High level of ownership and accountability; you see challenges through to the end
- Fluent in English (German is a plus)
What the job involves
- As a Data Engineer, you will play a key role in our App Team, acting as the go-to expert for energy telemetry data and pricing logic. This is a cross-functional, hands-on role with a strong emphasis on stakeholder communication, data ownership, and pipeline development
- Own and evolve our SQLMesh pipelines for data transformations across the app’s telemetry and pricing logic
- Build and maintain robust Python-based data ingestion pipelines for new and existing external data sources
- Maintain and evolve (GCP) cloud-native data infrastructure, ensuring performance and high availability in production
- Work closely with Product, Design, and other Engineering teams to define and deliver data that powers user-facing features, including price calculations, earnings, and savings
- Be the subject matter expert on telemetry data and energy price modeling, ensuring accuracy, reliability, and scalability
- Develop and maintain Looker dashboards for analytics, monitoring, and tracking key metrics for internal teams
- Ensure that telemetry measurements and price data are consistently available in the app, even under high load or during incidents
- Build and monitor CI/CD pipelines (GitLab CI, GitHub Actions) for reliable deployment of data products
- Design, implement, and monitor data quality checks to proactively catch and resolve issues
- Collaborate regularly with stakeholders across departments to investigate bugs, support rollouts, and inform product decisions
- Define and own key team KPIs and work proactively to improve them
Our take
As individuals and communities look to lower the carbon footprints of their buildings and homes, there is a need to access products and infrastructure that will enable them to adopt more eco-friendly energy practices. 1KOMMA5° is building a "one-stop shop" for sales, installation and services related to solar, power storage, and EV charging infrastructure, simplifying the energy transition for carbon-conscious people.

The company is also building a group of experienced specialist companies that it aims to support in aiding the clean energy transition, not only by investing in them but by granting them access to its operational experience to help them further develop.
A 2024 surge in revenue and profitability (leading to the company's unicorn status in 2023) underscores the market's confidence in 1KOMA5°'s transformative potential. With a clear trajectory towards exponential growth, fueled by ambitious revenue targets and strategic investments in product development, the company is poised to redefine the energy sector.
