Software Engineer

Job Title: Software Engineer

Location: Paris, Onsite, (we help you relocate)

About Plume: At Plume, we're at the intersection of two game-changing forces: AI and the energy transition. We're building an AI-powered platform that transforms how infrastructure gets built, starting with renewable energy projects. The world depends on infrastructure assets and renewable energy to function, yet selecting sites, connecting to local networks and getting permits is still too hard. We solve this challenge by combining geospatial data, unstructured data and AI workflows.\n\n

We are backed by Y Combinator and trusted by some of the most ambitious renewable developers in Europe and the US. This is where software meets the energy transition.

Role Overview You’ll design and build the hard technical systems that power Plume: large-scale geospatial pipelines, distributed spatial databases, AI agents over millions of planning documents, retrieval systems (RAG), text-to-SQL workflows, and decision engines that help developers identify, de-risk, and permit infrastructure projects.\n\n

You’ll still work closely with clients. You won’t just ship tickets; you’ll define what gets built and why. You act as a technical problem solver, a product translator, and a trusted partner for the customer, and you feed everything you learn back into the product. Your mission: build the operating system for developing the world's infrastructure.
