AI Engineer

About TemosThe energy transition has a bottleneck nobody talks about: access to the grid. Thousands of solar, wind, storage and industrial projects are stuck waiting for one answer: is there capacity to connect, and where?Temos is a fast-growing Barcelona startup building the intelligence layer for the energy industry, starting with that one very big problem: access to power and access to the grid. We turn fragmented, highly technical public data (grid operator capacity files, regulatory gazettes, permitting records) into products that developers, utilities and investors use to make multi-million-euro decisions.We are a small team with a high density of talent, coming from McKinsey, BCG and leading players in the energy space. More than a team, we are a tight-knit group of people who have each other's backs: we help each other, always look for what's best for the team, and share a deep sense of mission. We are growing fast, already working with major energy companies, and we have a clear ambition: to redefine how a traditional, trillion-euro industry makes decisions.The roleWe are looking for an AI Engineer to join our Product & Technology team in our Barcelona office.You are a builder at heart.
