Junior Software Engineering/Data Science in Renewable Energy Startup (x/f/m)

Software / Web Development

Exnaton is a spinoff company of ETH Zurich which offers software for renewable energy to energy companies. Our software enables energy providers to set up energy communities in their distribution areas. Users of our software can track their energy consumption and buy renewable energy from their neighbors, which makes investing in the energy transition simple and fun! Our software processes smart meter data and computes smart real-time prices for locally produced energy which make renewable energy financially more attractive. End-users receive an app that maps the sources of their energy, making their electricity consumption more understandable.

Our team consists of a diverse mix of engineers and business developers and we are all motivated to use technology to create a sustainable impact in our society. Our company will be growing in the next months and we are looking for motivated and passionate people to complement our team.

We operate a stack with a backend built in a strict micro-services pattern with polyglot services written in Python and TypeScript. Technologies are chosen to fit the purpose (e.g. time series, relational, no-sql databases). All deployments rely on Helm and run on platform-agnostic Kubernetes clusters. Our frontend is a Vue SPA (TypeScript) with a continuously extending feature set.

The job can be performed remotely in EU/EFTA states.


As a Software Engineer at Exnaton, you are one of our first 20 employees and shape the company and its vision from the ground up. Among others, your main responsibilities are the following:

  • Develop a state-of-the-art application for the energy sector
  • Building highly-reliable software
  • Operating customer deployments
  • Collaborate closely with our CTO to bridge the gap between the backend and analytical core of our product
  • As we are planning to grow the team in the next few years, you will ideally support and mentor new colleagues and review the team’s technical design, code, and documentation in the future


We define ourselves by a culture of collaboration and ownership. We’re looking for a driven, capable, and thoughtful person to add to our vision. The qualifications we are looking for in an ideal candidate are the following:

  • Degree in computer science, electrical engineering, statistics, mathematics, physics, engineering or relevant experience (we are happy to consider applicants without formal degree if you can demonstrate relevant skills);
  • Knowledge about data analytics and time series data;
  • Ideally, experience in developing software from prototype to production system;
  • Interest in renewable energy and understanding of energy systems is a big plus;
  • Motivation to learn new skills, make quick decisions, and clearly prioritize on what moves the needle;
  • Share our mission for sustainability and love what you do (and own it).


Our hierarchy is flat and communication direct, which means that we operate and learn fast, as a team. When working with us, you can expect the following:

  • Competitive salary and equity package
  • Learning opportunities to build up necessary skills
  • Flexible working hours (and partially location) as we believe in ownership and trust
  • Regular team events and exchange with other startups
  • Possibility to join remotely

We are dedicated to fostering diversity and to combat discrimination. We strongly encourage individuals from groups traditionally underrepresented in tech to apply and intend to consider all applications equally regardless of sex, ethnicity, ancestry, religion, national origin, sexual orientation, age, citizenship, marital status, disability, or gender identity. We won't inquire about how you identify or if you've experienced discrimination, but if you want to tell your story, we are all ears.

Sounds interesting?

Please attach your CV and ideally a link to your GitHub account to your application, cover letters are not required.
