Speechify

<div>Mission

Speechify is the easiest way to listen to the world's information. Articles on the web, documents in the cloud, books on your phone. We absorb it all and let you listen to it at your desk, on the go, at your own speed, and with tools that make learning easier, deeper, and faster.

What streaming services have done for audio entertainment, we're doing for audio information. And whatever we're doing seems to be working. We're #1 in our category, and experiencing exponential growth.

Overview

We're looking for a Senior Software Engineer to join our Core Experiences Team. This team builds and maintains the foundational services and SDKs that power Speechify's product experience across platforms.

<li>Ship cloud functions, lightweight backend services, and jobs using Kotlin</li>
</ul>
An Ideal Candidate Should Have
<ul>
<li>Systems thinking. You know that optimizing a system requires end-to-end design, and you believe simplicity is valuable.</li>
<li>Speed. You work quickly to generate ideas and options and know how to decide which things can ship now and what things need time</li>
<li>Focus. We're a high-growth startup with a busy, remote team. You know how and when to engage or be heads down</li>
<li>Collaboration. You know how to inspire, play, and negotiate with opinionated designers, marketers, and PMs</li>
<li>Preferred Tech Stack:
<ul><li>Kotlin Multiplatform (Java experience is OK but role is Kotlin Multiplatform)</li>
<li>Prior experience with GCP is a plus</li>
</ul>
</li></ul>What We Offer
<ul><li>A fast-growing environment where you can help shape the company and product.</li>
<li>An entrepreneurial-minded team that supports risk, intuition, and hustle.</li>
<li>A hands-off management approach so you can focus and do your best work.</li>
<li>An opportunity to make a big impact in a transformative industry.</li>
