Applied AI Engineer - LLM & NLP
JOB SUMMARY
Job details
At Toku, we create bespoke cloud communications and customer engagement solutions to reimagine customer experiences for enterprises.
We provide an end-to-end approach to help businesses overcome the complexity of digital transformation and deliver mission-critical CX through cloud communication solutions. Toku combines local strategic consulting expertise, bespoke technology, regional in-country infrastructure, connectivity, and global reach to serve the diverse needs of enterprises operating at scale. Headquartered in Singapore, Toku supports customers across APAC and beyond, with a growing footprint across global markets.
As an Applied AI Engineer at Toku, you will focus on building, improving, and deploying real-world AI capabilities across speech-to-text, chatbots, and large language model–driven features used in production.
This role combines hands-on model development with applied research, where you will evaluate existing approaches, explore new techniques, and translate research insights into practical improvements in live systems.
You will work closely with engineering teams to integrate models into production services while maintaining a strong delivery mindset.
You will thrive in this role if you enjoy balancing deep technical execution with curiosity-driven, applied research that directly shapes product outcomes.
Requirements
What you will be doingApplied AI Model Development:Train, fine-tune, evaluate, and improve NLP, speech-to-text, and LLM-based models used in production environmentsWork hands-on with chatbots, summarisation, and language understanding features, including retrieval-augmented generation (RAG) and vector-based retrieval systemsDesign and run model evaluations, benchmarking existing approaches and validating improvements before deploymentApplied Research Experimentation:Read, assess, and experiment with relevant AI/ML research and emerging techniques, translating promising ideas into practical, production-ready solutionsContribute to prompt design, model optimisation, and iterative experimentation to improve accuracy, latency, and reliability of deployed models
Product
ion Integration Delivery:Integrate models into existing backend services using Python-based APIs, collaborating closely with backend engineersEnsure models are production-ready, maintainable, and resilient when deployed in live customer-facing systemsSupport investigation and resolution of AI-related production issues in collaboration with engineering and platform teamsCollaboration Ownership:Work closely with engineering teams to align AI capabilities with product
