Job description

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’re looking for a Junior ML Engineer to join the growing ML team at Glite. We are building fundamental models for eduction - solving the ultimate learning task of predicting student knowledge and optimal ‘next task’ scheduling.

What you will do

• 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

Essential skills

• Bachelor's or master's degree in computer science or data science, or equivalent practical experience building ML solutions
• Knowledge of machine learning algorithms and metrics
• Understanding of neural networks, CNNs, RNNs, and transformers
• Knowledge of NLP algorithms
• Experience building automated ML pipelines
• Strong Python knowledge
• Experience using tools such as Pandas and NumPy for data manipulation and analysis
• Can speak, or is learning to speak, more than one language
• Complete end-to‑end ML experience - from finding and cleaning data all the way to monitoring models in production
• Understanding of CI/CD pipelines and automation tools for efficient model deployment and monitoring
• Experience with reinforcement learning
• Knowledge-sharing experience (tech talks, articles, YouTube videos, etc.)

What we can offer

• 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
• 25 days annual leave
• At least 3 interviews, which will involve 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 short project remotely with us, to learn what it’s like to work at Glite
