Job Description

Principal Machine Learning Engineer, Artificial Intelligence – AI

TTEC

• Architect and build large-scale ML systems spanning data, training, evaluation, inference, and deployment. • Design reproducible, high-performance training pipelines across GPU infrastructure. • Architect inference systems that balance latency, throughput, cost, and reliability at scale. • Design and maintain data systems for high-quality synthetic and real-world training data. • Implement evaluation pipelines covering performance, robustness, safety, and bias, in partnership with research leadership. • Own production deployment, including GPU optimization, memory efficiency, latency reduction, and scaling policies. • Collaborate closely with application engineering to integrate ML systems cleanly into backend, mobile, and desktop products. • Make pragmatic trade-offs and ship improvements quickly, learning from real usage. • Work under real production constraints: latency, cost, reliability, and safety

Job Requirements

  • Strong background in deep learning and transformer-based architectures.
  • Artificial Intelligence (AI) experience required.
  • Hands-on experience training, fine-tuning, or deploying large-scale ML models in production.
  • Proficiency with at least one modern ML framework (e.g. PyTorch, JAX), and ability to learn others quickly.
  • Experience with distributed training and inference frameworks (e.g. DeepSpeed, FSDP, Megatron, ZeRO, Ray).
  • Strong software engineering fundamentals; you write robust, maintainable, production-grade systems.
  • Experience with GPU optimization, including memory efficiency, quantization, and mixed precision.
  • Comfort owning ambiguous, zero-to-one ML systems end-to-end.
  • A bias toward shipping, learning fast, and improving systems through iteration.
  • Experience with LLM inference frameworks such as vLLM, TensorRT-LLM, or FasterTransformer.
  • Contributions to open-source ML or systems libraries.
  • Background in scientific computing, compilers, or GPU kernels.
  • Experience with RLHF pipelines (PPO, DPO, ORPO).
  • Experience training or deploying multimodal or diffusion models.
  • Experience with large-scale data processing (Apache Arrow, Spark, Ray).
