Staff Software Engineer 

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’re serving an orchestrated system of agents answering millions of contacts daily and expanding into other modalities like chat. The work breaks into vertical engineering, platform engineering, and inference & DevOps.

Responsibilities

Building AI voice agents that handle millions of real customer conversations; Expanding into other modalities like chat; Vertical engineering — building the agents themselves: complex multi-step customer workflows and deep integrations into contact center, order systems, healthcare workflows, and logistics; Platform engineering — the orchestration layer every agent runs on: routing, state, tool use, and primitives; Inference & DevOps — hosting our own models with low-latency serving at production scale plus telephony, observability, and deployment infrastructure; Working across the range from sitting face-to-face with customers to going deep on complex backend systems

Requirements

Real production experience. You’ve built and owned systems where failure had consequences. We don’t count years — we look at what you’ve shipped and what you learned shipping it.; Judgment that survives contact with production. Agentic development is how we work — but what we’re actually hiring is your experience: knowing what to ship, what to slow down on, and what never to ship at all.; Low ego, high execution. You own outcomes, not tickets. You’d rather ship the thing than present the plan for the thing.; Customer obsession. You want to be close to the problem — sometimes literally in the room — and you measure yourself by what the customer got.

Benefits

Comprehensive healthcare; Unlimited vacation; Mandatory half week off over July 4; Full week off at the end of the year; Eligible for equity in accordance with company policy and subject to board approval
