Role Overview

As a Senior Mobile Software Engineer , you will be a key contributor on the Android team, owning significant features and technical areas within the FlexCount mobile application. You will work on high‑scale, customer‑facing systems, collaborate closely with backend and product partners, and help raise engineering quality through strong design and execution. This role emphasizes hands‑on development, reliability, and performance rather than org‑wide technical leadership.

Key Responsibilities

• Design, develop, and maintain high‑quality Android features for a mission‑critical, enterprise‑scale application.
• Own moderately complex problem spaces within the mobile application (e.g., offline behavior, background processing, sync reliability).
• Collaborate with product managers, designers, backend engineers, and QA to deliver features safely and predictably.
• Diagnose and resolve performance issues, ANRs, and stability concerns in production environments.
• Contribute to improving mobile reliability, scalability, and user experience across a large device fleet.
• Follow and help evolve Android engineering standards, patterns, and best practices within the team.
• Write well‑tested, maintainable code and participate actively in code reviews.
• Support production incidents and participate in on‑call rotations when required.
• Mentor junior engineers through pairing, code reviews, and technical guidance.
• Contribute to tooling, libraries, or refactoring efforts that improve team productivity.
• Participate in sprint planning, estimation, and retrospectives as an engaged team member.

Required Qualifications

• 5+ years of professional Android development experience.
• Strong proficiency with Kotlin and modern Android development practices.
• Experience working on production Android applications with large user bases.
• Solid understanding of performance optimization, threading, and background execution.
• Experience building or maintaining offline‑capable or enterprise‑grade mobile applications.
• Ability to debug complex issues using logs, traces, and profiling tools.
• Experience collaborating in cross‑functional, Agile teams.
• Strong communication skills and a bias toward ownership and accountability.
• Experience implementing or using Real User Monitoring (RUM) to understand app performance and user journeys.

Preferred Qualifications

• Experience working with rugged or enterprise‑managed Android devices.
• Familiarity with device fleet management, MDM environments, or kiosk‑mode apps.
• Experience improving app startup time, sync performance, and responsiveness.
• Exposure to mobile CI/CD pipelines and automated testing frameworks.
• Contributions to internal libraries, shared components, or platform initiatives.

Why Join Us

• Work on a product used daily across thousands of retail locations globally.
• Be part of a collaborative team that values engineering quality and pragmatic solutions.
• Opportunity to grow technically and take on increased ownership over time.
• Competitive compensation, benefits, and long‑term career growth opportunities.
