OTE Group of Companies (HTO) Tech Stack
Greek telecom infrastructure operator with expanding ICT and AI capabilities
OTE Group is Greece's largest telecom operator, managing networks that serve the country's 10+ million people across fixed/mobile telephony, broadband, pay-TV, and ICT solutions. The tech stack reveals a dual operating model: mature infrastructure management (Kubernetes, WebLogic, Oracle) paired with emerging AI/LLM work (RAG, Python, Node.js). Active projects span observability, self-healing automation, and LLM evaluation—suggesting internal focus on modernizing operations and building AI-first developer tooling rather than shipping consumer products. Hiring acceleration in engineering and mid-to-senior roles indicates scaling pressure on feature velocity and security standards.
