• Identify and solve difficult technical and research-level problems.
• Build products end to end, from experimentation to user-facing applications.
• Bring depth in NLP, vision, and AI research.
• Find the next hard technical problem across the product and take it on.

Requirements

• Five or more years of experience on similar research or engineering problems.
• A strong record of solving hard problems in academic or industrial environments.
• The ability to manage scientific workflows and build robust, scalable products.
• Comfort reading, understanding, implementing, and ideally extending current AI research.

Nice to have

• Experience with NLP, LLMs, or other AI and machine-learning systems.

What Catapult offers

• Competitive salary and truly generous stock options.
• Comprehensive Bupa Private Healthcare and wellbeing allowances.
• A tax-efficient pension scheme with salary sacrifice.
• Generous workplace nursery benefit.
• 34 days of paid holiday, including public holidays.

• All the equipment you need to perform at your very best.
