Jobbeschreibung

Overview

Who is Preisenergie? Preisenergie develops pricing software for energy vendors. We help our customers calculate fair prices for a fully renewable and digital energy system. We model energy prices, simulate millions of alternative prices and choose optimal ones that best fit the goals of our customers (not always profit!). Our prices recover costs of individual consumers' energy consumptions and keep margins low enough to be competitive.

We are a close-knit team of eight and we like to celebrate with cake rather than with champagne.

Tech stack

• Backend: Python, FastAPI, pandas/polars
• Frontend: TypeScript, React, NextJS
• Database: PostgreSQL
• DevOps: Docker, AWS/GCP, CircleCI, Kubernetes, Argo

About The Job

In contrast to many junior roles, you won't be just another cog in the machine. We expect you to ship to production early and often.

• Design and implement a sleek new UI for our flagship product line (greenfield)
• Create rich data-driven interfaces, with interactive charts and visualizations
• Implement advanced UI requirements such as role-based feature variations and dynamic layouts
• Expand internal admin tools used by our own power users
• Contribute to our end-to-end testing pipeline and help maintain high QA standards
• Collaborate on observability efforts: expose metrics and logs, build data pipelines, and help improve monitoring and alerting
• Starting date: As soon as possible (or by mutual agreement)

About You

We believe that your mindset and your passion for learning are just as important as the specific technologies you've used.

• You have a solid foundation in computer science principles, whether from a university degree or equivalent hands-on experience. You understand the "why" behind the code you write.
• You've built backend services or APIs using a modern framework. If you've worked with FastAPI, that's fantastic! But if your experience is with Django, Flask, or similar frameworks in other languages, you'll get up to speed quickly.
• You are comfortable with modern frontend development. We use TypeScript, React, and Next.js, but if you have a background in another component-based framework like Vue or Angular, your skills will be highly transferable.
• You think beyond tickets. You engage with the underlying problem, explore pragmatic decisions and can explain trade-offs.
• You are eager to grow and take on responsibility.
• You have excellent communication skills
• You want to gain experience in data science and DevOps

Why should you join our team?

• Join a high-performing team (3x CDTM) with a proven business model
• Have immediate impact – we're a small team
• Develop fast through hands-on experience and a high degree of ownership
• Work on a meaningful mission to create a more sustainable and equitable energy future
• Build something in-person – our whole team is in Munich
