Job Description

Job SummaryYou will work on building a scalable distributed component-based AI platform includingadvanced natural language processing, configurable workflows, flexible APIs, business intelligence, sophisticated monitoring, self-healing operation and powerful featurerich UIs. You will build sophisticated omni-channel AI components including - natural language processing, transformers, neural nets, OCR, voice transcription, pattern recognition, proprietary domain model training and management. The team operates withan ultra-flat structure and encourages everyone to contribute to all aspects of business and product development.In one monthYou will have integrated into the team and absorbed the culture of our company. You will understand the product and the ways that use AI to interpret intent and extract entities from human communications. You will be immersing yourself in the code andgetting up to speed with our model development processes.In three MonthsYou will be up to speed and contributed to themodel codebase including research into the optimal tools to use including Logistic Regression, MLP, LSTM and Transformers as well as the many text pre-processing and embedding techniques that we use. Youwill be collaborating with the other technology team members on the technical design approach to ensure performance, reliability, and scalability.In six monthsYou will have become the go-to person for several AI techniques. You will be working with the rest of the team to define and progress the AI product roadmap. You will have trained, optimised, and delivered several production AI models for our clients.In 12 monthsWell wonder how we lived without you.Role DescriptionWe are seeking to hire an experienced, professional, and enthusiastic AI Engineer with a specialisation in Natural Language Processing to help us build our AI Software as a Service (SaaS) product.To succeed in this role, you should possess outstanding skills in statistical analysis, machine learning methods and text representation techniques as well as an appreciation of the in the field and commercial considerations.The role responsibilities include to:

• Assist with providing expertise in the Sales, PoC and engagement phases of projects

• Develop NLP systems according to product / client requirements
• Train the developed model and run evaluation experiments for client engagements
• Design and build a natural language processing infrastructure
• Create natural language processing pipelines to prepare data to feed to the classification and extraction algorithms
• Select and configure the appropriate neural net models to be trained for specific use cases
• Develop a library of components and business domain models that can be utilised across many clients
• Develop quantitative tools to measure model efficiency for use for PoC and live client engagements
• Build and maintain machine learning pipelines (currently in AWS Sagemaker)
• Implement model version control, training, evaluation, and optimisation tools
• Build the AI application components to a standard suitable for critical production processes
• Assisting in the deployment and support of AI models in the field ensuring that they are performing optimally
• Keep abreast of academic research to ensure that our product remains appropriately cutting edge
