Become part of trawa
Senior Software Engineer - Backend [Python]
What is trawa?
The energy sector is undergoing a major transformation. Traditional utilities are outdated, inflexible, and struggle to meet the demands of the modern economy – even though they are indispensable for millions of businesses.
This is a market with enormous potential, but the existing solutions are complicated, inefficient, and in desperate need of overhaul.
trawa is changing that. We are building the green utility of the future from the ground up. Our platform provides direct access to renewable energy for B2B industrial companies, develops innovative software to manage the volatility of the energy market, and professionalizes energy procurement on the buyer's side.
trawa is the energy provider of the future: a vibrant, breathing platform that evolves with the growth of our customers and helps them manage their energy supply sustainably – from small and medium-sized enterprises to global players and beyond.
