Applied AI Engineer – LLM, NLP

Toku

• Train, fine-tune, evaluate, and improve NLP, speech-to-text, and LLM-based models used in production environments • Work hands-on with chatbots, summarisation, and language understanding features, including retrieval-augmented generation (RAG) and vector-based retrieval systems • Design and run model evaluations, benchmarking existing approaches and validating improvements before deployment • Read, assess, and experiment with relevant AI/ML research and emerging techniques, translating promising ideas into practical, production-ready solutions • Contribute to prompt design, model optimisation, and iterative experimentation to improve accuracy, latency, and reliability of deployed models • Integrate models into existing backend services using Python-based APIs, collaborating closely with backend engineers • Ensure models are production-ready, maintainable, and resilient when deployed in live customer-facing systems • Support investigation and resolution of AI-related production issues in collaboration with engineering and platform teams • Work closely with engineering teams to align AI capabilities with product requirements and platform constraints • Communicate progress, trade-offs, and technical decisions clearly in planning and delivery discussions

Job Requirements

  • Strong hands-on experience with LLMs, NLP, or speech technologies, including training, fine-tuning, and evaluating models in real-world or production contexts
  • Practical experience with Python-based AI development (e.g. PyTorch and related ecosystems)
  • Hands-on experience reading, evaluating, and applying AI/ML research (e.g. papers, benchmarks, emerging techniques) and translating those insights into production-ready model improvements
  • Experience deploying or supporting AI models in production systems, including exposure to monitoring, iteration, and real-world failure modes
  • Ability to integrate models into existing backend services via Python APIs and work effectively within a microservices-based environment
  • Familiarity with retrieval-augmented generation (RAG), embeddings, and vector-based retrieval systems
  • Working knowledge of AWS-based environments and AI tooling (e.g. EC2, SageMaker, MLflow, Docker)

Benefits

  • Discretionary Yearly Bonus & Salary Review
  • Healthcare Coverage based on location
  • 20 days Paid Annual Leave (15 days for Malaysia based roles), plus other leave allowances
