Integration Engineer

Molecule Software | Poland (Office) Molecule is a modern ETRM platform built for energy trading companies across power, natural gas, renewables, and financial commodities. We're growing our integration capability and looking for an Integration Engineer to own the technical connectivity that sits at the heart of every client implementation. The role You'll design, build, and maintain the integrations that connect Molecule to the systems our clients depend on — market data providers, exchange platforms, generation data sources, ERP and CRM systems, SCADA historians, and downstream analytics infrastructure. You'll also build custom reports in SQL, turning client data into the insights they need. This is an end-to-end ownership role: from integration design through to testing, documentation, and handover.
