Speechify is a fast-growing AI-powered audio platform that converts written content (articles, documents, books) into high-quality audio, making information accessible and consumable on-the-go. 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, SDKs, and infrastructure that power 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, and navigate integration/UX tradeoffs across different product teams - Deliver solutions via Speechify's cross-platform SDK - Optimize existing functionality to ship faster loading times and more intelligent parsing by designing efficient abstractions and improving algorithms - Ship cloud functions, lightweight backend services, and jobs using Kotlin Ideal candidates demonstrate systems thinking (understanding that optimizing requires end-to-end design and valuing simplicity), speed (quickly generating ideas and knowing what can ship now vs. later), focus (managing engagement in a high-growth, busy, remote environment), and strong collaboration skills with designers, marketers, and product managers. Preferred tech stack: Kotlin Multiplatform (Java experience acceptable but role focuses on Kotlin Multiplatform), with GCP experience 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—including those with learning differences like dyslexia, ADD, low vision, and autism.
