Overview
AfterQuery brings on data scientists and ML practitioners for short project-based engagements, each running roughly two to three weeks. You accept work as it fits your schedule, usually 10 to 20 hours a week, and the tasks mirror what a data science, machine learning engineering, or AI research team handles day to day. Models you build and evaluate feed real business applications, from predictive modeling through documentation of assumptions and results. The company is early-stage and backed by Y Combinator, so the problems stay varied and the datasets do too.
What You'll Do6
- Build, train and evaluate machine learning models that answer a defined business question.
- Design predictive models with supervised and unsupervised learning methods.
- Improve model results through hyperparameter tuning and feature engineering.
- Record methodologies, model assumptions and technical approaches so the reasoning survives handoff.
- Carry a task from initial scoping through final results with little supervision.
- Work through unfamiliar datasets and pick the modeling approach that fits them.
Requirements5
- 1 to 3 years of professional experience in data science, machine learning or a closely related field.
- Master's degree in computer science, statistics, mathematics, data science or another quantitative discipline.
- At least one first-author publication, or work of comparable first-author weight.
- Record of solving technical problems without close supervision.
- Preferred: experience as a teaching assistant for machine learning, data science or applied statistics courses built around programming and empirical analysis.
Who Should Apply
Early-career data scientists and ML practitioners who hold a master's in a quantitative field and can point to at least one first-author paper. The work suits someone who takes a modeling task, runs it alone, and documents why each choice was made.
Salary Insight
The listing posts $80/hr, and the company describes project pay as starting near $60/hr and reaching $100/hr depending on the assignment. That band runs above typical early-career data science contract rates, which tracks with the master's degree and publication bar.
