Role description
Senior SWE - Python / TypeScript - USA (Contract)
CareerflowCareerflow Human Data Labs partners with AI companies to bring real-world professional expertise into their products.
About the Role:
We're looking for a high-taste engineer with a strong eye for quality — someone who's worked hands-on with preference data and rubric creation, and knows what separates a good example from a great one. You communicate clearly and can synthesize complex technical work the way a strong MAI dev would: concise, structured, and easy for others to act on. You're comfortable in ambiguous, fast-moving environments and default to shipping over deliberating.
What does day-to-day look like:
Design, refine, and iterate on rubrics and evaluation criteria for preference data
Review and label data with a high bar for quality, catching subtle issues others might miss
Build and maintain pipelines/infra that support data generation, collection, and evaluation workflows
Synthesize findings from data work into clear write-ups, updates, or recommendations for the team
Collaborate closely with researchers/engineers to translate qualitative judgment into scalable processes
Required Skills:
5+ yrs of proficiency in Python (especially building/maintaining pipelines and infra) or Typescript/Golang/JavaScript (experience contributing to or navigating large codebases like VSCode a plus)
Hands-on experience with preference data collection and/or rubric creation
Strong written and verbal communication — able to distill technical work into clear, actionable summaries
Demonstrated high-taste judgment — able to articulate why something is good, not just that it is
Work in a fully remote environment.
Opportunity to work on cutting-edge AI projects with leading LLM companies.
