Job description

1komma5° At 1KOMMA5° , we pursue a clear vision: Living on wind and sunlight forever for free . To make this a reality, we are building the energy system of the future with Heartbeat AI. Want to be part of it? We bring together regional craftsmanship and scalable software: We don't think of solar, batteries, heat pumps, and e-mobility as isolated components, but control them as an intelligent, integrated overall system in our virtual power plant. Directly connected to the electricity market - in real time, fully automated. This way, energy is used when it is available from renewables and particularly cost-effective. By 2030, our goal is to transition 1.5 million households to renewable energies. Over 3,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia.

As a member of the B2C domain, you will build a virtual power plant leveraging our energy manager "Heartbeat", and continuously ship innovative energy market solutions to our customers. You will be responsible for developing scalable, robust backend services that enable seamless integration of our energy management solutions with various energy markets.

Key responsibilities

• Work collaboratively with product managers, data engineers, and data scientists to understand problems, support discoveries, and create solutions our customers love
• Build and optimize backend services for VPP operations and energy market integrations
• Design and implement APIs and abstraction layers for seamless communication between different components of our energy market integration solutions
• Optimize backend services for scalability and support for a large number of connected users
• Create, implement, evaluate, and deploy software solutions to solve complex problems in a simplified way
• Foster a culture of experiment-driven innovation within the team

• Google Cloud Platform (Cloud Run, Cloud Functions, PubSub, CloudSQL, Firestore, BigQuery)
• Domain-driven design architecture
• Datadog
• Terraform
• GitHub Actions

The successful candidate will have

• Proven experience in developing scalable backend solutions with TypeScript from several past projects
• Competence in building virtual power plant infrastructure, including the integration into energy markets (day-ahead, intraday, balancing services, etc)
• Hands-on experience working with interfaces in the context of energy services (e.g., smart meters, energy optimization, load balancing)
• Broad knowledge of various architectural patterns and experience implementing them with CI/CD using GitHub Actions and cloud infrastructure (ideally GCP)
• Passion for maintainable, documented, reusable, and testable code
• A finger on the pulse of software engineering trends and industry best practices
• An agile and product-oriented mindset and you consider yourself a team player
• Very strong written and spoken English skills, German is a plus

Bonus points for

• Experience with IaC (ideally Terraform)
• Experience Python in the context of Data Engineering or Machine Learning
• Experience with IoT applications for grid balancing and demand response
