Software Engineer (Mid+)

O projekcie: About Actaware Actaware is an AI startup building a deterministic, auditable intelligence platform that transforms millions of unstructured documents - PDFs, filings, reports, earnings calls - into decision-grade insights for investment managers and enterprises. Our stack powers explainable LLM pipelines, dynamic ontologies, and agentic document processing at scale, serving clients across financial markets and the public sector. We're a small, sharp team of engineers, data scientists, and domain experts who ship fast and solve hard problems. If you want to work at the intersection of AI, data infrastructure, and high-stakes decision-making - this is the place. The Role We're looking for a Software Engineer who can own features end-to-end - from designing cloud infrastructure to shipping production ML pipelines. You'll work across the full stack of our platform: building scalable services, automating deployments, and integrating AI/ML components into a product that real customers depend on daily. This is not a ticket-punching role. We need someone who sees a problem, figures out the best path forward, and executes - without waiting to be told what to do.
