Speechify is the leading text-to-speech platform that transforms how people consume information—articles, documents, books—by converting them to audio. 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: - Collaborate with Product Teams to scope projects, reduce scope for faster customer feedback, navigate integration/UX tradeoffs, and deliver solutions via cross-platform SDK - Optimize existing functionality to ship faster loading, more intelligent parsing, and improved algorithms through better abstractions - Ship cloud functions, lightweight backend services, and jobs using Kotlin Ideal candidates demonstrate systems thinking (understanding end-to-end design and valuing simplicity), speed (quickly generating ideas and knowing what ships 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: Kotlin Multiplatform (Java experience acceptable but role is Kotlin-focused), with GCP experience a plus. The role offers a fast-growing environment where you can shape the company and product, an entrepreneurial team supporting risk and hustle, hands-off management, and the opportunity to impact millions of users—including those 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.
