Our mission is to inspire a lifelong love of reading by providing unlimited access to thousands of high-quality books, videos, and educational content through a safe and engaging experience. We combine technology, storytelling, and learning innovation to help every child become a confident reader.</p> <p data-start="467" data-end="638">At Epic, you’ll join a collaborative and fast-paced global team passionate about building meaningful products that make a real impact on children’s education and literacy.</p> <h2 data-section-id="115i9ww" data-start="640" data-end="659">Position Summary</h2> <p data-start="661" data-end="1214">The<span class="Apple-converted-space">&nbsp;</span><strong data-start="665" data-end="721">Senior Software Engineer, Full-Stack — Content Tools</strong><span class="Apple-converted-space">&nbsp;</span>owns the internal tools and pipelines that bring Epic's library of books, audio, and learning content from raw assets through to production-ready, app-consumable formats. You will design, build, and operate the Angular-based content workbench and the PHP/Go services behind it—turning long, manual content-prep workflows into automated, high-throughput pipelines, and partnering with our content, editorial, and platform teams to make the tools more capable and the operators more productive.</p> <p data-start="1216" data-end="1637">You are an experienced engineer who works independently on complex problems, makes sound technical decisions, and pulls in the right people when a decision touches another team. Our back-end is multi-language: PHP/Symfony powers our long-standing application code, and we are actively investing in Go for newer services—senior engineers help drive that evolution thoughtfully rather than reflexively rewriting what works.</p> <p data-start="1639" data-end="1751">This role works in close partnership with Epic's global engineering team across the US, China, Spain, and India.</p> <h2 data-section-id="18w7bso" data-start="1753" data-end="1776">Key Responsibilities</h2> <ul data-start="1778" data-end="3954"> <li data-section-id="1c523za" data-start="2483"
