Speechify is the leading text-to-speech platform, making the world's information accessible through 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 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 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 and more intelligent parsing through efficient abstractions and algorithm improvements - Building 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 (managing engagement and deep work in a high-growth remote environment), and collaboration (inspiring and negotiating with designers, marketers, and PMs). Preferred tech stack includes Kotlin Multiplatform (Java experience acceptable but role is Kotlin-focused) and prior GCP experience is 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, competitive salaries, and the opportunity to impact millions of users with accessibility-focused technology at the intersection of AI and audio.
