Speechify is the leading text-to-speech platform that converts articles, documents, and books into audio, enabling users to consume information while commuting, working, or learning. The company is #1 in its category and experiencing exponential growth. You'll join the Core Experiences Team, which builds and maintains the foundational services and SDKs powering Speechify's product across all platforms. This is a critical role at the intersection of product and infrastructure, requiring strategic thinking and a passion for designing clear, reliable APIs and simple systems that directly enhance user experience. Key responsibilities include: - Collaborating with Product Teams to scope projects, reduce scope for faster customer feedback, navigate integration/UX tradeoffs, and deliver solutions via cross-platform SDK - Optimizing existing functionality to ship faster loading times and more intelligent parsing through efficient abstractions and algorithm improvements - Shipping cloud functions, lightweight backend services, and jobs using Kotlin Ideal candidates demonstrate systems thinking (understanding that optimization requires end-to-end design with a focus on simplicity), speed (quickly generating ideas and knowing what can ship now vs. later), focus (thriving in a high-growth, busy, remote environment), and collaboration (inspiring and negotiating with designers, marketers, and PMs). Preferred tech stack includes Kotlin Multiplatform (Java experience acceptable but role focuses on Kotlin Multiplatform) and prior GCP experience is a plus. The company offers a fast-growing environment where you can shape the product, an entrepreneurial team that supports risk and hustle, hands-off management, competitive salaries, and the opportunity to impact millions of users with learning differences like dyslexia, ADD, low vision, and autism. You'll work at the intersection of AI and audio, one of tech's fastest-growing sectors.
