Full Stack Engineer

Full-Stack Engineer (React Native Mobile + Flask Backend)

About Us

GLEN operates across Security, Traffic Control, Childcare, Recruitment, and other industries.

We are building a Dispatch & Scheduling Platform to manage a growing field workforce. The system handles employee scheduling, SMS confirmations, automated replacements, and a mobile app used by field employees.

This role focuses on building the core operational platform — not website development.

Role Overview

You will work on the core system powering workforce operations, including:

• A Flask backend handling scheduling logic, APIs, SMS workflows, and background jobs

• An admin dashboard used by dispatchers to manage schedules and employee responses

• A React Native mobile app for employees to receive shifts, confirm work, and record timesheets

• Real-time status updates for scheduling, SMS notifications, and employee responses

The system must scale to ~1,000 users across web and mobile.

Responsibilities

Backend (Flask)

• Build and maintain APIs for employees, jobs, schedules, confirmations, and messaging

• Implement rule-based scheduling logic (conflict detection, availability filtering, replacement logic)

• Develop background workers (Celery or similar) for SMS sending and long-running tasks

• Design APIs for mobile syncing, including offline submissions and geo-location validation

Admin Dashboard

• Build tools for dispatchers to create schedules, manage assignments, and monitor employee responses

• Implement responsive and efficient interfaces for operational workflows

Mobile App (React Native)

• Develop the employee mobile app for receiving shifts, confirming work, and communication

• Implement geo-tagged timesheets with clock-in / clock-out functionality

• Capture GPS location during clock-in/out and validate job-site proximity

• Support offline-first behavior with automatic syncing when connectivity returns

Quality & System Design

• Debug issues across backend, dashboard, and mobile app

• Write scalable and maintainable code for a system supporting ~1,000 users

• Optimize APIs, database queries, and scheduling workflows

Qualifications

• 2+ years of professional software development experience preferred

• Strong experience with Python (Flask) and API development

• Experience building mobile apps with React Native

• Familiarity with background workers (Celery or similar)

• Experience with SMS APIs (Clerk Chat or similar)

• Strong debugging ability across backend and mobile systems

• Proficiency with Git and collaborative development workflows

Note: This role involves developing a live operational system used for real-time workforce scheduling and mobile field operations. Developers with prior experience working on production systems and complex backend workflows will be best suited for the role.
