Junior Rust Developer Jobs in Rutherford, NJ (NOW HIRING)

Kira is a rapidly growing startup backed by top-tier Venture Capital funds including New Enterprise Associates (NEA), Andrew Ng’s AI Fund, and Primavera.

• Familiarity with automated testing, CI/CD pipelines, and reliable deployment practices

• Impeccable attention to detail

• (Preferred) Extensive experience contributing to frontend codebases (e.g., React, TypeScript)

• (Preferred) Experience with integrating LLM-backed services, including API usage, evaluation, and operational considerations
