Job Description

About Us

Epic Kids is the leading digital reading platform built for kids 12 and under, trusted by millions of children, educators, and families around the world. 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.

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.

About the Role

The Senior Software Engineer, Full-Stack owns features end-to-end across Epic's web application -- Angular front-end, PHP/Symfony and Go services, MySQL -- and helps raise the engineering bar for the team. We hire for engineering strength over experience with any specific stack; strong engineers ramp quickly on ours.

This is a fully remote, US-based role working closely with a global engineering team with members in the US and China.

What You'll Do

Design and ship features end-to-end across the full stack, from spec to production.
Make sound decisions on architecture, data modeling, and API design; document trade-offs and align stakeholders.
Drive code quality through code review and testing across front-end and back-end.
Mentor junior and mid-level engineers through code review and pairing.
Lead technical design reviews, RFCs, and architecture discussions.
Use AI-assisted development tools to accelerate delivery, holding generated code to the same quality bar.
Participate in production support -- investigations, post-mortems, and systemic fixes.

What We're Looking For

Required Qualifications

5+ years of professional software engineering, owning complex, cross-team work autonomously.
Bachelor's degree or higher in Computer Science, Software Engineering, or a related field.
Strong front-end engineering with a modern component framework (Angular a plus), plus solid TypeScript/JavaScript and UI fundamentals (HTML, CSS, accessibility).
Strong back-end engineering in a modern server-side language (we use PHP and Go).
Relational-database proficiency -- data modeling, performant queries, and indexing.
Experience designing and operating production APIs (REST or gRPC).
Comfort with Git, pull-request workflows, and CI/CD.

Preferred Qualifications

Direct experience with our stack (Angular, PHP/Symfony, Go, MySQL) a plus.
Experience leading a service migration between languages/runtimes (e.g., PHP to Go) in production.
Familiarity with Tera for server-side templating.
Experience with Docker and Kubernetes (GKE) at the application-developer level.
Cloud-platform experience -- GCP preferred, AWS or Azure acceptable.
Experience operating against an observability stack (New Relic, Datadog, or similar).
Awareness of children's-privacy compliance frameworks (COPPA, FERPA).
Proficiency in Mandarin Chinese a plus.

Compensation: 160-210k - inclusive of bonus - flexible for the right skillset
