Popsa

Senior Data Scientist

Soho, London Full Time
Right now is one of the most exciting moments to join Popsa. Deloitte named us one of the UK’s fastest-growing technology companies, and the Financial Times recognised Popsa among the Top 5 fastest-growing software companies in Europe.

We’re backed by world-class investors, and the world is noticing. Our iOS and Android apps are available in 12 languages, trusted by more than 12 million people who have created over 5 million photobooks shipped to 50+ countries. With more than 350,000 five-star reviews, we’re one of the highest-rated consumer apps anywhere.

But the real story isn’t the numbers, it’s the memories behind them.

We’re living in a time where we capture more photos than ever before. Billions of moments sitting unseen in camera rolls and clouds, mixed with screenshots, receipts, or where we parked the car. We are great at documenting life… but not so great at preserving the meaning in it.

Popsa is changing that.

Since launching in 2016, we’ve built an award-winning platform that removes every barrier to transforming your favourite memories into something beautifully tangible. No design skills. No time-sink. Just the joy of holding real stories in your hands. A celebration of the people and moments that make life worth living.

This is only the beginning.


About the Role
You'll design, train, and deploy machine learning systems that directly impact millions of users; from computer vision models that understand photo libraries at scale, to generative AI features that write captions, suggest titles, and curate personalised "Memories" albums. You'll own the full lifecycle from prototyping to production, collaborating closely with engineering and product teams to ship features that help people rediscover the moments that matter.
