Responsibilities
Research and develop Machine Learning models as described above. Optimize models for scaled production usage
Work with colleagues in the AI team, other Engineering teams, subject matter experts, Product Management, Marketing, Sales and Customer support to explore ongoing product issues, challenges and opportunities and then recommend innovative ML/AI based solutions
Help out with ad-hoc one-off tasks as a team player within the AI team
Work with subject matter experts to curate and generate optimal datasets following responsible data collection and model maintenance practices. Explore and access local datastores as well as web data and write efficient parallel pipelines. Review and design datasets to ensure data quality
Investigate weaknesses of models in production and work on pragmatic solutions
Modify and fine-tune off the shelf models or develop novel models. Use LLMs via API (through prompt engineering and agents) and locally hosted LLMs and other foundation models
Stay current in the field - read research papers, experiment with new architectures and methods, and share your findings
Write clean, efficient, and modular code with automated tests and appropriate documentation
Stay up to date with technology and platforms, make good technological choices, and be able to explain them to the organization
Work with downstream teams to productionize your work and ensure that it makes into a product release
Communicate insights, as well as the behavior and limitations of models, to peers, subject matter experts, and product owners
Present and publish your work
Qualification
Required
Master's degree or PhD in Computer Science, Electrical Engineering, AI, Machine Learning, applied math or related field or outstanding previous achievements demonstrating excellence in Deep Machine Learning, Computer Science and Software Engineering
At least 10 years of industry experience in Machine / Deep Learning (we use the python ecosystem for ML), Computer Science and Software Engineering
A strong understanding of the math and theory behind machine learning and deep learning is a prerequisite
Academic publications in peer reviewed conferences or journals related to Machine Learning - preferably A/A+ rated such as NeurIPS, ICML, ICLR, AAAI, TMLR, JMLR, IJCAI, ICANN, KDD, ACL, EMNLP, NAACL, COLING, CVPR, ICCV, ECCV, IEEE etc
Machine / Deep Learning development skills, including popular platforms (we use AWS SageMaker, Hugging Face, Transformers, PyTorch, PyTorch Lightning, Ray, scikit-learn, Jupyter, Weights & Biases etc.)
An understanding of Language Models, using and training / fine-tuning and a familiarity with industry-standard LM families
Excellent communication and teamwork skills
Fluent in written and spoken English
Preferred
We're an applied science group (vs fundamental research), therefore Software development proficiency is a requirement
Experience working with text data to build Deep Learning and ML models, both supervised and unsupervised. Experience with deep learning in other modalities such as vision and speech would be a strong bonus
A Computer Science educational background is preferred as opposed to statistics or pure mathematics
Reinforcement learning
Interpretability of deep neural networks
Experience with advanced prompting / agentic-systems and fine-tuning or training an LLM, using industry accepted platforms
Showcase previous work (e.g. via a website, presentation, open source code)
Familiarity in building front-ends (Gradio, Streamlit, Dash or more standard React, Javascript, Flask) for simple demos, POCs and prototypes
Essential dev-ops skills (we use Docker, AWS EC2/Batch/Lambda)
Familiarity in coding for at-scale production
