Senior Full-Stack Engineer

Epic Kids Inc. is a leading digital reading platform for children (ages 12 and under), used by millions of kids, families, and educators worldwide. Our mission is to unlock the potential of every child through reading. We offer a vast library of high-quality books, audiobooks, and educational resources, delivering personalized reading experiences powered by data and engagement insights. As we continue to scale globally, we are investing in intelligent infrastructure and AI-driven systems to modernize how content is ingested, processed, and delivered to young readers everywhere.

We’re looking for a Senior Full-Stack Engineer who is a specialist in media automation and machine learning-driven workflows (OCR, TTS, and Computer Vision). In this role, you will be the primary architect responsible for transforming our content ingestion process into a high-velocity, automated pipeline. You are an engineer who can move seamlessly between high-level Angular frontend development and the low-level Python/PHP backend logic required to process complex media.

Your mission is to bridge the gap between raw data and usable content. You will focus on optimizing the precision of automated text extraction and audio synchronization, ensuring that even complex or non-standard content layouts are parsed accurately and presented through a high-performance, interactive UI.

• ML Pipeline Orchestration: Design and refine workflows for OCR and Speech-to-Text, focusing on spatial accuracy, coordinate mapping for non-standard layouts, and font recognition.
• Automated Media Alignment: Build and maintain engines to synchronize multi-format assets, such as aligning full-book audio narrations with document text through automated time-stamping and segmentation.
• UI Interaction & State Management: Lead the development of the Angular content workbench, resolving complex state issues and ensuring that interactive elements (like coordinate-based "word boxes") are responsive and precise.
• Backend Infrastructure: Optimize the PHP 8.1 API to handle high-volume file transfers and background processing tasks, ensuring the system can scale with large media assets (100MB+).
• Format Conversion & Parsing: Develop automated ingestion tools for complex document formats (e.g., ePUB, PDF, and XML), extracting and transforming embedded data into application-ready formats.
• Continuous System Optimization: Identify and resolve architectural bottlenecks in the content pipeline, focusing on reducing manual intervention through smarter algorithmic processing and UI automation.

Required:

• Full-Stack Proficiency: 7+ years of experience across Angular (14+) and PHP (8.x).
• ML/Media Integration: Proven experience integrating and fine-tuning ML-driven services for OCR (e.g., Google Vision, Tesseract) and Audio Transcription (e.g., Speechmatics, AWS Transcribe).
• Advanced Python: Strong background in Python 3 for media manipulation, subprocess orchestration, and data transformation.
• Media Engineering: Expert-level knowledge of FFmpeg, ImageMagick, and browser-based media libraries (e.g., wavesurfer.js, cropperjs).
• State Management: Mastery of RxJS and reactive programming patterns (e.g., NgRx) for handling high-density, real-time UI interactions.

Desired:

• Experience with digital publishing standards and the internal structure of ePUB or ONIX files.
• Knowledge of Canvas-based coordinate systems for drawing and rotating interactive elements over media.
• Familiarity with containerized deployments (Docker/Kubernetes) for media-heavy processing applications.
