Wagestream is on a mission to bring better financial wellbeing to frontline workers.
We partner with some of the world’s most famous employers, like Bupa, Burger King, Greene King and the mighty NHS to give their teams access to fairer financial services - all built around flexible pay. Over three million people can now choose how often they’re paid, track their shifts and earnings, start saving, use budgeting tools, get free financial coaching, and access fairer financial products. All in one financial wellbeing super-app.
Wagestream is unique: VC-backed and growing at scale-up pace, but with a social conscience. Some of the world's leading financial charities and impact funds were our founding investors, and we operate on a social charter - which means every product we build has to improve financial health and reduce the $5.6bn ‘premium’ lower-income earners pay for financial services each year.
You’d be joining a team of over 200 passionate, ambitious people, across Europe and the USA, building a category-leading fintech product and all united by that same mission.
The Opportunity:
Wagestream is hiring a hands-on Head of Data Science to lead and grow our Data Science team and drive data-informed decision-making across the organisation. This is a critical leadership role responsible for setting the direction of Data Science at Wagestream, building a high-performing team, and ensuring the delivery of impactful data products.
We believe that Data Science consists of 4 key elements:
- Data Analysis
- Includes data cleansing, writing complex SQL queries and using commercial understanding to deliver actionable insights.
- Includes creating dashboards and reports in various formats so as to make data more understandable to all stakeholders.
- Includes writing Python, following SDLC best practices, using Git, and creating data products in dbt.
- Includes experiment design and analysis, causal inference, hypothesis testing, feature engineering, and ML model development and deployment.
You don't have to be great at all of these areas for us to want to talk to you. We want to help you grow and develop your skills in areas you are less familiar with over time.
The Team:
You will lead and manage our team of embedded Data Scientists, and report directly to the CTO. You will collaborate closely with other department heads (e.g. Operations, Product, Engineering) to align data science initiatives with overall business objectives.
