Job Description
Software Engineer
Fastino Labs
• Ship full-stack features end-to-end, owning the full lifecycle from conception to production with minimal oversight. • Build and maintain the infrastructure powering Fastino's services, keeping systems reliable and performant as we scale. • Work directly with AI researchers to bring new model capabilities into the product, moving fast without sacrificing quality. • Translate user feedback into product improvements, closing the loop quickly between what customers experience and what gets shipped. • Collaborate daily with the full team to review progress, surface blockers, and keep velocity high.
Job Requirements
