Senior Marketing Manager

About GuavaGuava is building voice AI that actually works in production. Our agentic speech platform is engineered for the environments where voice is not optional — call centers, hospitals, financial services, automotive systems, robotics, and aerospace. Unlike brittle demos, Guava holds context, switches modalities, and persists until tasks are complete. We run on proprietary ASR, TTS, and language models built together from the ground up, not stitched together from third-party APIs. Our team is composed of world-class experts in speech technology from Stanford, MIT, and NASA. We have processed billions of minutes of voice annually, and our customers include BPOs, hospitals, and financial institutions with real compliance requirements. We are SOC II, PCI, and HITRUST ready. This is not a research project — it is production infrastructure, and we treat it that way.

That means setting the strategy, writing the copy, owning the channels, running the campaigns, and iterating fast — all at once. The upside is real: you will have direct influence over how one of the most technically differentiated voice AI companies in the world presents itself to the market. You will work closely with the founding team, have meaningful equity, and leave fingerprints on everything. What You Will OwnAs Guava's sole marketer, your scope is intentionally broad. On any given week, you might be refining our positioning for a new vertical, writing a technical deep-dive for our developer audience, coordinating a customer case study, or analyzing what is and is not converting in our pipeline. Specifically, you will be responsible for: - Brand & Positioning. You will own Guava's voice in the market — literally and
