About Siera Sinclair

Principal Sound Designer & Creative Leader | Audio Director | AI Voice Design | Composer | Haptics Design | Speaker I design sonic experiences that connect - emotionally, intuitively, and at scale. My work spans composing for feature films, engineering for Grammy-winning artists, defining sonic brand identities across product and marketing, and pioneering UX sound design systems used by over 3 billion people. I’ve led AI audio and voice design, developed immersive audio for AR/VR and next-gen platforms, and shaped audio ecosystem strategy across wearables, mobile, and emerging hardware — guiding teams and driving creative vision end-to-end. I use sound to create meaning, build trust, and improve accessibility. Whether in technology, film, or games, I focus on crafting sonic experiences that serve users and move people. My goal is to make products and narratives sound more intuitive, expressive, and human. As a collaborative leader, I unite cross-disciplinary teams and elevate diverse voices to deliver work that resonates. Whether composing for film, designing conversational UX sound, or speaking about the future of audio, I aim to inspire and connect through sound.
