There is no organization in the world that understands voice better than Deepgram. Company Operating Rhythm At Deepgram, we expect an AI-first mindset—AI use and comfort aren’t optional, they’re core to how we operate, innovate, and measure performance. Every team member who works at Deepgram is expected to actively use and experiment with advanced AI tools, and even build your own into your everyday work. We measure how effectively AI is applied to deliver results, and consistent, creative use of the latest AI capabilities is key to success here. Candidates should be comfortable adopting new models and modes quickly, integrating AI into their workflows, and continuously pushing the boundaries of what these technologies can do. Additionally, we move at the pace of AI. Change is rapid, and you can expect your day-to-day work to evolve just as quickly. This may not be the right role if you’re not excited to experiment, adapt, think on your feet, and learn constantly, or if you’re seeking something highly prescriptive with a traditional 9-to-5. Opportunity: Saga is Deepgram’s consumer facing application - this application lets people control their tools, workflows, and environments using natural speech. Deepgram Saga is an innovative voice OS designed for professionals, enabling hands-free control of their workflow through natural language. It integrates seamlessly with existing tools like Slack, Linear, and Notion, allowing them to execute tasks via voice commands, thereby reducing context-switching and enhancing productivity.
