Our client is a subscription-based fitness and mobility platform with a global community of athletes and everyday movers. Their product combines a custom-built Flutter mobile app (iOS/Android) and a WordPress/WooCommerce backend, featuring custom REST API plugins and subscription integrations.

The team is currently focused on stabilizing and strengthening the existing platform — fixing bugs, improving security, and ensuring smooth performance across both the app and backend, especially in subscription and in-app purchase (IAP) workflows.

Job Description

We’re looking for a Full-Stack Engineer experienced in both Flutter/Dart (mobile development) and WordPress/PHP (custom plugin and REST API development).

This role will take ownership of in-app purchase flows (Apple/Google IAP) and ensure they are correctly integrated with WooCommerce/Chargebee subscription systems. The engineer will work hands-on resolving issues, tightening security, and improving the overall stability and reliability of the platform.

Responsibilities

Diagnose and resolve bugs across the Flutter mobile app and WordPress/PHP backend.
Maintain and extend custom WordPress REST API endpoints consumed by the mobile app.
Ensure secure handling of authentication, tokens, and API integrations.
Maintain and troubleshoot Apple/Google IAP flows and ensure correct reconciliation with WooCommerce/Chargebee.
Support and improve subscription/payment flows across mobile and backend systems.
Collaborate on CI/CD workflows (GitHub Actions) for testing and deployment.
Write clean, maintainable code following best practices for version control and secrets management.
Provide technical input on improving stability and security across the stack.

Technical Requirements

Must-Have Skills (Mid-Senior Level):

3+ years of professional software engineering experience.
Strong hands-on experience with Flutter/Dart, including publishing apps to TestFlight and Google Play.
Proficiency in WordPress/PHP, including custom plugin and REST API development.
Proven experience implementing and maintaining Apple App Store and Google Play IAP flows (ideally in Flutter).
Experience with WooCommerce and subscription/payment integrations (Chargebee, Stripe, or similar).
Strong understanding of authentication, secure storage, and API security best practices.
Experience debugging and resolving issues across mobile and backend systems.
Working knowledge of Git, GitHub, and CI/CD pipelines.
Excellent communication skills and the ability to explain technical concepts clearly.
Advanced English communication skills (B2+ or C1), both written and spoken, to effectively collaborate with a U.S.-based team.

Desired Skills (Nice to Have):

Familiarity with MySQL performance tuning in WordPress environments.
Exposure to cloud services (AWS, Firebase) and secrets management.
Experience with analytics integrations (Amplitude, Mixpanel, or similar).
