Senior Data Scientist Assessment at Udemy

Description
As Udemy looks toward the future of online education, skill assessments lie at the heart of promoting learner progression and growth. Udemy’s skill assessment group is looking for a data scientist with a strong background in psychometrics, statistical modeling, machine learning, and hands-on experience with empirical research methods in the social sciences.
As a data scientist at Udemy, you will be partnering with product managers, designers, and engineers to build algorithmic and model-driven solutions to power skill assessments. This role will require a combination of applied measurement experience, data-driven decision making, and the data science and coding chops to dive headfirst into development on production systems. A successful candidate will have knowledge of best industry practices for growing and maintaining a large set of assessment products, while being courageously experimental in finding new solutions to ongoing issues in test development and maintenance.
Here Are Some Questions You Could Be Working On:
What is the appropriate methodology for equating/linking assessments on our platform?
How do we best maintain and utilize operational item banks?
What other user activities can be used as indicators of learning?
How do assessment results relate to other user outcomes?
How do users engage with other learning products after completing assessments?
How can content recommendations be improved using assessment outcomes?
Here Is What You Will Be Doing:
Collaborate with other data scientists, PMs, designers, and engineers to maintain and grow our skill assessment platform
Effectively communicate and present to both technical and non-technical audiences
Critically evaluate and implement the state-of-the-art research literature in educational assessment
Develop production-grade data pipelines and continuously improve the quality and accessibility of data
Develop psychometric models for skill assessment through all phases, including prototyping, productionization, and experimental evaluation
Define metrics and build dashboards to track the adoption and health of skill assessments
Collaborate with content developers and instructional designers to develop and refine item writing and review processes
We Are Excited About You Because You Have:
3+ years of hands-on industry experience in a psychometric or data science-oriented role
Domain experience in educational assessment and psychometrics (e.g., Classical Test Theory (CTT), Item Response Theory (IRT), Computerized Adaptive Testing (CAT), equating and scaling) 
Strong SQL ability and proficiency with 1+ programming languages (e.g., R or Python)
End-to-end experience organizing and analyzing large data sets for operational purposes
Ability to communicate effectively with non-technical stakeholders
Strong knowledge of applied statistics and experimental design
Ability to work autonomously, relentlessly prioritize, and collaborate with team members across time zones
We Are More Excited About You Because You Have:
5+ years of relevant industry experience
Experience with machine learning and causal inference
Familiarity with standard software engineering practices (e.g., Scrum)
Experience using big data technologies (e.g., Hadoop, Spark)
Minimum Salary Expectations:  125,000
