Lead ML Engineer (London)

We are a small London startup with the ambition to change education with ML-powered tutoring. Our flagship product is a mobile application for teaching English to intermediate and advanced learners. We’re on the verge of solving one of the biggest challenges in education – making high-quality, personalised learning accessible to everyone. We are building a fundamental model for education - one that can accurately predict student knowledge and orchestrate lessons, adapting to the students' needs.

We’re looking for a Lead ML Engineer, with a proven track record of delivering ML models to production, to own the ML team in our growing company.

What you will do:

• Build fundamental models for education - solving the ultimate learning task of predicting student knowledge and optimal ‘next task’.
• Work with a vast amount of unique data - we have data from over 1M language tests, including text and voice data.
• Create brand new dictionaries, applicable to any context - right now it’s the English language, but in the future it could be other languages or even subjects such as Mathematics.
• Analyse large amounts of diverse data - including data from every movie, book, and song.
• Work in a cross-functional team and communicate with backend engineers and product managers.
• Create new types of tests for language learners to gather more test results, analyse them, and build prediction models based on these results.
• Optimise and fine-tune machine learning models for performance, scalability, and accuracy.
• Lead our ‘AI Powered Education’ meet-up in London, building a network of ML specialists.

Essential skills:

• Experience leading and mentoring other ML engineers.
• Complete end-to-end experience - from finding and cleaning data all the way to monitoring models in production.
• Experience taking complete ownership of entire ML systems and data pipelines in large-scale production systems.
• Experience building automated data pipelines.
• Strong understanding of CI/CD pipelines and automation tools for efficient model deployment and monitoring.
• Strong understanding of neural networks, CNNs, RNNs, LSTMs, and transformers.
• Great knowledge of NLP algorithms.
• Expertise in using tools such as Pandas and NumPy for data manipulation and analysis.
• Expertise in Python and PyTorch.
• Can speak, or learning to speak, more than one language.
• Experience with reinforcement learning.
• Knowledge-sharing experience (tech talks, articles, YouTube videos, etc.).

What we can offer:

• Lead an ML team that will become the leading specialists in ML-powered education.
• A real-deal startup adventure: you'll be hopping on a major project while it’s still in the works!
• Freedom to suggest, implement, and test ideas.
• Lunch provided by the company every day.
• Work from our London office.
• 3 interviews, which will be a mixture of technical and non-technical tasks.
• If all the interviews are successful, we’d like to invite you to 2 or 3 paid trial days, or to complete a short project remotely with us, to learn what it’s like to work at Glite.
