Job overview and responsibilities

• Syensqo is a leading multinational materials company headquartered in Brussels, advancing humanity through scientific exploration and innovation. Nearly two years after the spin-off from Solvay, Syensqo.ai has evolved from inception to a nimble, high-impact scale-up that accelerates AI adoption across the Group—partnering closely with corporate functions (e.g., Finance, HR, Legal, Procurement), operations, and our chemists and researchers.

  We operate lean and fast, with a startup mindset and strong governance: deliver impact quickly, build responsibly, and meet enterprise standards for security, compliance, ethics, and guardrails. 
  
  As a Data Scientist, you will design experiments and productionize machine learning and generative AI capabilities on Azure, focusing on measurable business outcomes, reproducibility, and MLOps best practices. You will collaborate directly with stakeholders, guide technical decisions, and help shape patterns and standards for agentic AI within the enterprise.

  This role will focus on SyGrow. SyGrow is Syensqo.ai’s sales copilot initiative. In this role, you will turn sales and stakeholder needs into data products—exploring new features, validating hypotheses, and shipping ML- and LLM-powered capabilities that drive commercial impact. You balance fast iteration with enterprise-grade practices in data, MLOps, and Responsible AI.
