Job Summary
The mission for the role:
At Popsa data drives growth and were scaling fast. With over 5 million customers and more joining every week our data science team plays a pivotal role in this growth by developing and executing the business data strategy to build meaningful connections with audiences.
Were looking for a highly skilled and driven Senior Data Scientist who can design train and deploy advanced machine learning systems at scale. Youll work across computer vision natural language processing and recommendation problems training convolutional neural networks on large image datasets fine-tuning large language models and optimising for production use both on servers and on edge. Youll also help design and maintain our FastAPI services that deliver these models into production collaborating closely with engineers and product teams to build features that directly impact millions of users.
This is a really exciting opportunity for someone keen to be at the cutting edge of generative AI using machine learning to identify patterns and develop visualisations to tell compelling data-driven stories for a diverse customer base.
Who we are:
Joining Popsa right now is pretty exciting. According to Deloitte we are one of the UKs fastest-growing tech startups and in 2022 the Financial Times ranked us in the Top 5 fastest growing software companies in the whole of Europe.
We have the backing of some of the best investors in the world. Our native iOS and Android apps are available in 12 languages attracting more than 5 million users to date and we ship to over 50 countries around the world.
People have never taken more photos than we do today. Our phones are crammed with memories. But although were good at capturing moments were not as good at doing anything with them. Theyll often sit forgotten on our devices or in the cloud shrouded in screenshots receipts and pictures of where we parked the car.
Founded in 2016 weve already built an award-winning app thats made printing your memories so easy and accessible anyone can do it. No more barriers. No more fact everything we do as a business is designed with this ethos. We help people turn their best moments into something beautiful and lasting in no time at all. But this is just the start
Today were best known for photobooks but our vision of the future goes far beyond print. Popsa is building a new generation of services that combine artificial intelligence and thoughtful design to support a healthy processing of the meaningful events and relationships in your life.
Exciting projects
- Develop large-scale personalised curation systems that process entire photo libraries applying computer vision and machine learning to detect events relationships and themes and automatically generate structured Memories albums at scale
- Apply generative AI across the company - from real customer-facing product features such as title suggestions (look out for our AWS blog coming soon) and captions to internal systems such as customer support
- Build and deploy large-scale convolutional neural networks trained on tens of millions of images with datasets growing daily
- Scale inference and serving infrastructure our FastAPI servers handle millions of requests in production
Core responsibilities
- Design train and deploy Machine Learning models that directly impact customers every day
- Clean transform and prepare data for analysis handling missing values and inconsistencies to ensure reliability
- Own the full stack of data science development: from prototyping models to production deployment and monitoring
- Extract insights from large complex datasets (structured and unstructured) to identify trends build predictive models and develop algorithms for creative applications
- Collaborate closely with product engineering and marketing teams to ship features end-to-end
- Contribute to improving infrastructure for large-scale training testing and evaluation
- Present data findings and insights in a meaningful and visually compelling way to technical and non-technical stakeholders including creative teams and leadership
- Design and conduct statistical experiments to evaluate creative strategies and optimise outcomes
- Continuous Learning - stay updated on the latest advancements in data science software and tools and knowledge share
Key experience
- Excellent coding ability in Python
- Solid experience with SQL
- Strong understanding of statistics data mining and predictive analytics techniques
- Hands-on experience with Docker and Terraform
- Exposure to AWS (e.g. S3 ECS SageMaker EC2)
- Experience deploying and testing generative AI models in production
- Comfort with engineering-heavy workflows (CI/CD containers infrastructure)
- Experience developing and applying various machine learning algorithms including classification regression and clustering
- Excellent verbal and written communication skills to effectively convey complex findings and stories to diverse audiences
- Analysis of user data to personalise content improve engagement and optimise user journeys
- Experience with recommender systems
- Familiarity with large-scale training pipelines (distributed training GPU scaling)
- Experience with multi-head CNN architectures or multi-task learning for robust model training
- Contributions to open source technical talks or side projects showing initiative
Ideal but not essential:
We may use artificial intelligence (AI) tools to support parts of the hiring process such as reviewing applications analyzing resumes or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
