The posting

About Reel

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.

How you can contribute

As our new Senior Software Engineer, you will be directly helping companies achieve lower electricity costs and drive real climate impact. You will work closely with Christian, our CTO, and the rest of the engineering and product team to build the software powering the renewable energy transition.

What your role will look like

These are some (not all) of the things you will be working on:

  • Build and maintain key backend systems: From our electricity billing engine handling accurate and on-time billing, to leading the technical work for entering new markets.
  • Build the data backbone of our platform: Design and maintain the pipelines and backend systems that ingest, process, and serve large amounts of real-time energy data reliably and at scale.
  • Build for scale: We are growing fast - in volume under management and geographically - and you will be part of building the infrastructure to support that growth.
  • Ship user-facing features with real impact: Contribute to the analytics and platform tools our customers rely on daily to understand their consumption, production, and emissions.
  • Raise the bar and help set the direction: Perform code reviews, share feedback with colleagues, contribute to key technical decisions, and be a core member of the team shaping how our tech evolves.

We think you will thrive in this role if

You have shipped a lot of 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 - but you'll be curious to learn. You might also recognise yourself in some of these:

  • You have solid experience building and maintaining backend systems in production.
  • You enjoy taking projects from idea to shipped, and like to ship often.
  • You care deeply about reliability and want to stay close to production.
  • You default to simple, pragmatic solutions.
  • You work well independently, make decisions with confidence, and know when to bring others in.
  • You enjoy sharing knowledge and helping others level up.
  • Curious about how AI tools can help us ship better software as a team.

We work in Elixir, using the Phoenix framework and LiveView + TypeScript for the front-end. We use Python for ML and trading. We're hosted on GCP, data in Postgres w. TimeScale and BigQuery. Experience in this stack is by no means a requirement - several engineers on the team today had no prior experience in Elixir.

Please note that we are located in Copenhagen, Denmark and this is an in-office role with flexibility for hybrid work.

Working at Reel

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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
