🚀 About the Team

We’re a focused team composed of a Data Scientist, a Frontend Engineer, and two Full-Stack Engineers, structured around two core pillars:

• Metrics – We own the full stack of our metrics engine, from data ingestion to frontend presentation. If it touches metrics, it’s our domain.
   
• AI – We develop and maintain AI capabilities, support cross-org AI needs, and lead efforts in prompt engineering and integration of intelligent features.

We move fast, collaborate deeply, and take pride in building systems that are both technically sound and impactful.

What You’ll Do

• Design, build, and maintain scalable backend services powering our Metrics and AI pillars.
• Own key components of our metrics engine, including data modeling, pipeline architecture, and performance optimization.
• Collaborate with data scientists and AI engineers to productionize models, build APIs, and support AI integrations.
• Provide internal tooling and backend services that enable prompt engineering and AI capability reuse across teams.
• Partner with frontend engineers to create seamless data experiences and metrics visualizations.
• Contribute to architectural decisions and drive technical excellence across the stack.
• Write well-tested, maintainable code and establish backend best practices.
