Senior/Staff Backend Engineer (SDE-4)
100% Remote (EST)
6 months +
Location Requirement: Flexible (Remote open across U.S. time zones)
Overview
Client is hiring for two backend engineering roles: a Senior Back End Engineer IV (SDE IV) and a Back End Engineer III (SDE III) to support a growing product initiative within the 10-4 platform.
This is a backend focused engineering role supporting a consumer facing mobile application, representing one of client s first B2C initiatives. While the platform includes payment capabilities, the broader focus is on building scalable backend services that support mobile experiences, including location services, APIs, and microservices architecture.
These are high impact individual contributor roles. The team is not looking for managers or leads, but rather strong engineers who can come in, operate autonomously, and execute with minimal oversight. Candidates must be able to understand existing systems, contribute to feature development, and work through engineering backlogs efficiently.
A key differentiator for this team is a strong emphasis on intellectual rigor, authenticity, and problem-solving ability. The interview process is designed to assess real world thinking, not memorized or AI assisted responses. Candidates are expected to demonstrate their own reasoning, approach, and coding ability during live technical evaluations.
