Senior Full-Stack Engineer

Project Overview

We are developing a cutting-edge, high-performance Trading Card Game (TCG) mobile application. The platform leverages advanced computer vision to allow users to scan physical cards via their phone camera, identify them instantly, fetch real-time market pricing, and seamlessly manage digital collections.

As a Senior Full-Stack Engineer, you will have a massive impact on the project. You will own the end-to-end user journey—from building the low-latency mobile interface that interacts with the device's camera, to designing the scalable backend APIs and data pipelines that power the entire experience.

Core Responsibilities

• End-to-End Development: Architect, build, and maintain both the cross-platform mobile frontend and the robust backend APIs supporting it.

• Camera & UI Integration: Implement high-performance mobile camera interfaces and real-time UI overlays to ensure a seamless, instant card-scanning user experience.

• Backend & API Design: Design and optimize scalable microservices, RESTful/GraphQL APIs, and database schemas to handle heavy traffic and real-time pricing updates.

• Data & Pipeline Collaboration: Integrate frontend experiences with backend image processing and machine learning pipelines for instant card recognition.

• Performance Optimization: Optimize mobile app performance (framerate, memory usage, image caching) and backend latency to deliver a premium user experience.

• Technical Leadership: Drive code quality through rigorous code reviews, establish full-stack engineering best practices, and mentor junior/mid-level team members.

Required Qualifications

• Experience: 5+ years of professional software engineering experience, with a proven track record of shipping production-ready mobile apps and backend systems.

• Frontend/Mobile Stack: Strong experience with cross-platform mobile frameworks (Flutter) and handling native device features (Camera APIs, image manipulation, local storage).

• Backend Stack: Strong proficiency in Java, RocketMQ and gRPC , with deep knowledge of relational databases (MySQL & Redis)

• System Architecture: Experience designing distributed systems, microservices, secure authentication (OAuth/JWT), and third-party API integrations.
