As part of one of our teams around Heartbeat AI, you will help building our virtual power plant leveraging our energy manager "Heartbeat", and continuously ship innovative energy market solutions to our customers.
This is a builder role at the intersection of engineering and product: you co-own the product, define what gets built together with your cross-functional team, ship it fast, and use AI as a force multiplier along the way.
Cloud Architects and SREs will enable you to easily deliver and run software in a consistent, secure, and reliable way.
Own feature development end-to-end, from problem framing through production deployment to long-term maintenance
Define feature scope together with PMs and engage with the "why", not just the "what"
Drive technical decisions and guide fellow engineers on architectural choices
Keep feedback loops short: prototype, ship to real users, observe, adjust
Use AI tools to amplify your impact and explore AI-powered product opportunities where they make sense
Push back when something doesn't make sense and propose a better direction
Improve developer experience by reducing tech debt, automating workflows, and documenting decisions and runbooks
