About PYYNE Digital

PYYNE is a modern technology consultancy engineering the next generation of digital products and services.

At PYYNE, we believe in using technology to unlock business potential, create sustainable growth, and drive forward digital excellence. Our solutions range from advanced Software Engineering, Cloud, and Data & AI solutions.

Job Summary

PYYNE is seeking a Mobile Engineer to build a greenfield MVP mobile application. This is a full-stack mobile engineering role focused on rapid development, real-time interactivity, and responsive user experiences.

You'll work closely with our Tech Lead to architect, build, and refine a high-quality, scalable app from the ground up. This position is ideal for a developer who thrives in fast-paced environments and enjoys solving complex problems with clean, maintainable code.

Key Responsibilities

App Development:

  • Design, build, and deploy a performant cross-platform mobile app using React Native and TypeScript.
  • Implement UI components using Shadcn and follow responsive, mobile-first design principles.
  • Handle real-time interactions via WebSockets, Socket.IO, or GraphQL subscriptions.

API & Data Integration:
  • Connect front-end components to REST or GraphQL APIs for dynamic content and real-time updates.
  • Collaborate with backend engineers to define API specs and optimize data flows.

Testing & Deployment:
  • Write and maintain automated tests using Jest and React Testing Library.
  • Set up and manage basic CI/CD pipelines with GitHub Actions and Docker.
  • Assist with publishing to Play Store and App Store (experience is a plus, but not required).

Collaboration & Innovation:
  • Work with product and UX/UI designers to implement sleek, intuitive interfaces.
  • Leverage AI tools like Cursor, GitHub Copilot, ChatGPT, or Gemini to accelerate development.
  • Participate in agile planning, code reviews, and sprint retrospectives.

Qualifications

Required Skills:
  • Strong experience with React Native and TypeScript.
  • UI/UX sensibility with experience building user-friendly, visually engaging interfaces.
  • Hands-on knowledge of real-time data handling (e.g., WebSockets or GraphQL subscriptions).
  • Familiarity with REST or GraphQL API integration.
  • Proficiency in automated testing with Jest and React Testing Library.
  • Working knowledge of Docker, CI/CD workflows, and GitHub Actions.

Bonus Skills:
  • Experience deploying apps to the Play Store and App Store.
  • Exposure to Mobile Configuration Profiles (MCP).
  • Previous work on betting or real-time interactive apps.

Other Requirements:
  • Able to work independently in a fast-moving environment with minimal supervision.
  • Comfortable collaborating remotely with designers, engineers, and stakeholders.

The Ideal Candidate

You're a self-motivated mobile developer who enjoys building high-quality, user-centered apps from scratch. You're fluent in modern mobile development best practices and comfortable owning the full stack—from real-time data integration to pixel-perfect UI. You're curious about new tools and excited to push the boundaries of what's possible with React Native.
