TITLE: Staff Software Engineer REPORTING TO: CTO LOCATION: Marina del Rey, CA – OR – Williamsburg, NY (onsite M – F) Who is Flip? Flip creates AI voice agents that manage millions of real customer conversations for major brands, healthcare providers, and transportation companies worldwide. When you call a company and the AI genuinely resolves your issue — tracking an order, processing a return, refilling a prescription — that's us. We operate as a low-ego team. We don't seek the spotlight — we focus on solving hard problems quickly. Notably, outside the frontier labs, almost no one runs AI in production at this scale. We do — millions of live phone calls handled by an engineering team far smaller than you'd expect. Very few teams our size handle this volume, because we maintain a very high bar for development. How we think: From day one, we have operated on first principles, with the customer as the first principle. If you have strong conviction that something delivers real business value for your customer, it should not get stuck in red tape or committee deliberation. You ship it — quickly and often — because the customer matters most. That is why there is a direct line from your keyboard to production. We did not remove the committee to move fast for its own sake; we removed it because conviction combined with customer obsession does not need a permission slip. Agentic development has changed our workflow — we make no secret of that. What it has not changed is the necessity of experience, particularly at the production level. You can ship faster than ever now; that does not make experience irrelevant. Speed without judgment is how you break things millions of people depend on. That is why this posting asks for senior and staff engineers: we are hiring builders whose experience makes the new speed safe. Our philosophy is straightforward: let builders build. We care considerably less about stack experience or corporate background than most companies — and considerably more about whether you have looked beyond the noise and want to build product you are genuinely proud of. Tools change monthly now. The instinct to build does not. We keep the team lean on purpose — a high bar, real support, real resources — because that is where builders truly express themselves. The most common feedback we hear from engineers after joining Flip is some variation of "I could never have done this at my last company." Deep industry expertise paired with disciplined execution produces outstanding work. That is the formula. What you will build: We serve an orchestrated system of agents answering millions of contacts daily and are now also expanding into other modalities such as chat. Pulling this off requires elite engineering combined with outstanding DevOps — voice is unforgiving: it is real-time, there are no retries or page refreshes, and the customer is literally on the line. The work spans three lanes: Vertical engineering — building the agents themselves: complex multi-step customer workflows and deep integrations into the contact center and the industries we serve — order systems, healthcare workflows, logistics. This is where "mostly works" is not shippable. Platform engineering — the orchestration layer every agent runs on: routing, state, tool use, and the primitives that allow vertical teams to ship fast without rebuilding the engine. Inference & DevOps — we host our own models; low-latency serving at production scale is a core competency here, not a vendor line item. Plus the telephony, observability, and deployment infrastructure that keeps millions of live calls healthy. The range here is real. Our engineers do everything from sitting face-to-face with customers to going deep on complex backend systems — you genuinely get to choose where you fit. We do not slot you into one of these on day one. There is probably a place for you — we will find it together, and it will likely change as we grow. What we look for: We intentionally wrote this as one role for senior and staff engineers, because we believe builders love to build — and how they build varies. Some want the flexibility of working alone and joining forces when it matters; some do their best work in a small pod. We do not prescribe it. What we do hold as a core principle: we are always raising the bar on each other. As we grow, our best builders often end up with two or three engineers building behind them — if that is a direction you want, it is here. And if you would rather remain a pure builder, that raises the bar too. Real production experience. You have built and owned systems where failure had consequences. We do not count years — we look at what you have shipped and what you learned shipping it. Judgment that survives contact with production. Agentic development is how we work — but what we are 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 would 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. More About Us: We are international, spanning the US, UK, and Canada. We have raised +$30M to date including our recent $20M Series A — backed by Ridge, Next Coast, ScOp, Bullpen Capital, Data Point and Forum Ventures, as well as founders & executives from Amazon Alexa, Ada, Attentive and Simon Data. Our tech stack includes Python, MongoDB, AWS, Twilio, Datadog, Snowflake, and Omni. Comprehensive healthcare and unlimited vacation, including a mandatory half week for everyone over July 4, and a full week off at the end of the year. In the office 5 days/week, we collaborate in real time on the desk. Final compensation may vary based on location, experience, and qualifications. This role is also eligible for equity, in accordance with company policy, and subject to board approval. Compensation Range: $200,000 — $400,000 USD. Our customers span the globe, and so do our offices. Flip is committed to providing equal employment opportunities for all employees, applicants, and covered individuals regardless of protected characteristics. We want our company to be as diverse and inclusive as our customers.
