Senior/Staff Software Engineer
About The Position
Flip builds AI voice agents that handle millions of real customer conversations for some of the biggest brands, healthcare providers, and transportation companies in the world. We are a low-ego team focused on solving hard problems quickly. Our engineering team operates at a scale rarely seen, handling millions of live phone calls with an AI system. We operate on first principles, prioritizing customer value and enabling direct lines from keyboard to production. Agentic development has changed our workflow, but experience remains crucial for safe and effective production-level work. We value builders with experience who can make new speeds safe, focusing more on product building and less on stack experience or corporate pedigree. We maintain a lean team with a high bar, providing real support and resources for builders to express themselves. Our engineers often report being able to accomplish more at Flip than at previous companies due to deep industry expertise and ruthless execution.
