We are rethinking electricity to accelerate the transition to a carbon-free energy system.
Electricity is one of the biggest sources of carbon emissions globally, yet most green power sold on the market today fails move the needle toward decarbonizing electricity production.
Reel empowers companies to move beyond climate commitments and achieve real-world carbon reductions, by bridging the gap between renewable energy producers and consumers.
Join our mission-driven, cross-disciplinary team of developers, builders, and climate experts working to accelerate the transition to a net-zero economy.
We’re working with some of the most exciting technologies within energy, delivering renewable power to corporates and balancing production from asset owners. We’re optimizing solar parks, wind farms, and grid-scale batteries, trading across different markets and providing ancillary services to help stabilize the grid.
At the end of each month, we’re condensing all of this activity into a few numbers on an invoice for each of our customers. That’s only possible with a strong, purpose-built energy billing platform.
As our new Software Engineer for billing, you’ll own and grow our next-generation energy billing platform. You’ll work closely with Christian, our CTO, the rest of the engineering team, and our electricity operations team.
These are some (not all) of the things you will be working on:
You have shipped production software and know how to get things done. You take real ownership of your work and have a bias for shipping. You don't need to know anything about energy today or have years of experience with energy billing - what matters most is that you're eager to learn and ready to put in the work.
You might also recognise yourself in some of these:
We work in Elixir and Python. We're hosted on GCP, use Kubernetes, data in Postgres w. TimescaleDB and BigQuery, and observability using Loki, Prometheus, and Grafana. We strive to keep our infrastructure as code with tools like Terraform and ArgoCD. Experience in this specific stack is by no means a requirement.
Please note that we are located in Copenhagen, Denmark and this is an in-office role with flexibility for occasional hybrid work.
At Reel, we care deeply about our people. We offer a workplace that values initiative, ownership and kindness, with ample room for personal and professional growth. We believe great teams are built by welcoming people with different backgrounds, perspectives, and lived experiences.
You will join a tight-knit team on an ambitious journey, where the impact of your role will be visible and recognisable on a daily basis. Every colleague - from founders to student assistants - are in this together. We cherish focus and autonomy just as much as team work and setting time aside for having fun together - at our monthly socials, bi-annual offsites and daily coffee chats in our bright and spacious office in central Copenhagen, 2 minutes from the metro.
