The company

Prolific ( brings people together to power the world’s research. It is the first scientific, highly scalable, ethical participant recruitment platform for researchers around the world. Quantitative and qualitative researchers, data scientists, and entrepreneurs all need valid and reliable data sources to make predictions about human behaviour, social change, and global developments. Thanks to our online platform, researchers collect responses fast and participants earn cash rewards for themselves or for charity. It takes 5 minutes to start data collection, there's no middleman, and the product easily integrates with any survey software. In a world of unreliable results, Prolific makes data trustworthy and connects the public with science.

The role

In this role you will develop and implement data analyses, data collection systems, and other strategies that help us better understand user behaviour as well as our business and product performance. You will be analysing data using statistical techniques with a focus on understanding our growth engine, users’ full life cycle, data quality, and user demographics (for representative sampling): How does Prolific currently acquire, convert, and retain its users (both Researchers and Participants)? And what can be done to improve user acquisition, conversion, and retention? What are the current demographics of the pool, and what differences are there to the general population? Which participants are the most honest and engaged, and which are not?

You will have an opportunity to learn about the startup ecosystem, about the lean startup approach, and about user acquisition techniques and growth strategies. More broadly, you will get the chance to learn about business and product development, data science, and diverse research areas in the social and natural sciences.

This is your chance to get involved in a fast-moving startup where you’ll have huge influence over the trajectory of the product. Since it’s a startup, you’ll have the opportunity to suggest how you can best add value, and make any recommendations about improving the processes and product. We're a fast-growing company and we want to help you grow with us.

Working closely with our analysis team, developers and leadership you will work towards these key goals:

Analyse what drives the growth of our platform and what is the best allocation of resources in order to improve this growth
Improve the quality, the honesty, and engagement of Prolific’s participant pool through analysis of user behaviour and collection of new data
Improve the diversity and representativeness of Prolific’s participant pool by ongoing monitoring of demographics
This will likely involve some or all of the following:

Analyse key growth metrics, retention, stickiness, churn over time and determine causal links between product changes and growth. Work closely with management and use these data to influence key decisions and help our startup grow quickly
Use analytics software such as Amplitude to create visualisations, segment our user base, and develop dashboards to track key growth, data quality, and demographic metrics over time
Develop a clear understanding of our community and intersect this qualitative data with quantitative data and develop a plan of key questions to answer with data
Extract data from non-SQL/SQL databases for analyses in a reproducible way for downstream analysis or work closely with developers in order to achieve this
Statistically analyse large data sets (millions of rows) and draw robust conclusions from these data with the understanding that large data sets are messy, and it is easy to draw incorrect conclusions from these data if our analyses are not robust
Develop attention checks, consistency checks and longitudinal measures designed to track participants’ consistency, honesty, and engagement
Proactively suggest new questions to ask, new data to collect, or product changes to make based on insights from data
Generate regular reports in a reproducible manner which clearly and accurately describe the collection, organisation, and analysis of your data
Disseminate the key information to the whole organisation in written reports and summaries, which highlight the key insights you’ve gained and which are easily interpretable and actionable

Salary: £28,000-32,000 (p.a.), negotiable based on experience and qualifications, plus:
Pension (employer contribution 3% of base salary)
Flexible working: Work equipment of your choice, you can work flexibly from home or from our coworking space, flexible hours
25 days holiday per year, plus bank holidays
Flexible budget for any books and/or educational material
Personal growth opportunities (e.g., learn about the startup ecosystem, mentoring from executive team, learn about psychological science and research methods)
Open, transparent, and inclusive culture
Self-made cider and home-baked cookies :-)
