About The Position

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 organization-wide technical leadership. The role involves designing, developing, and maintaining Android features for a mission-critical, enterprise-scale application; owning moderately complex problem areas such as offline behavior, background processing, and sync reliability; and collaborating with product managers, designers, backend engineers, and QA to deliver features safely and predictably. You will diagnose production performance and stability issues, contribute to mobile reliability and user experience across a large device fleet, follow and improve team engineering practices, write tested and maintainable code, participate in reviews and production support, mentor junior engineers, improve team tooling, and engage in Agile planning and retrospectives. The position is full-time and hybrid in the office in Plano, Texas. Work is primarily sedentary and requires frequent use of a computer, keyboard, and mouse. WIS states that it provides reasonable accommodations to qualified individuals with disabilities and is an Equal Opportunity Employer committed to a diverse and inclusive work environment.
