Senior ML Engineer at Kiefer Tech designing and optimizing AI systems for Greece and the EU. Focus on ASR pipelines, model performance, and multi-agent AI frameworks in a hybrid work environment.
Responsibilities
Build and scale production-grade ASR and LLM pipelines, improving throughput, latency, and reliability while ensuring full data sovereignty.
Improve model performance through dataset-centric optimization, expanding Greek-language and domain-specific capabilities.
Design and deploy scalable multi-agentic AI systems to automate complex enterprise document analysis and decision workflows.
Drive cost and performance optimization for model inference, reducing cost-per-task through quantization, caching, and smart routing.
Define and uphold ML engineering standards, including evaluation frameworks, ML CI/CD, testing, and mentorship across the ML team.
Requirements
Deep experience in AI orchestration with tools like LangGraph, CrewAI, or MCP for building multi-agent systems.
Proven ability to use vLLM, TensorRT, or quantization (AWQ/GGUF) to scale throughput.
ASR Expertise and hands-on work with Whisper or Kaldi, specifically optimizing for non-English languages.
Proficiency in synthetic data generation and fi-tuning for specialized domains (Legal/Finance).
Advanced Python, PyTorch, and Docker skills; familiarity with MLOps and CI/CD for AI.
Ability to design systems, not just write scripts, with a focus on data sovereignty.
High agency and ownership, AI curiosity and structured mindset.
Fluent in Greek and English.
