Software Engineer III, Device Connectivity
About this role
Flock is seeking a Software Engineer III to architect and optimize cellular connectivity for edge camera devices deployed across outdoor environments. You'll advance their Android-based system stack through a 5G upgrade roadmap, manage low-level OS initialization, and ensure fleet stability under strict power constraints in challenging field conditions.
What you'll do
- Develop and optimize AOSP cellular connectivity stack for LTE/5G modems, Radio Interface Layer, and eSIM configurations
- Engineer low-level Android OS initialization, image partitioning, file systems, and SELinux security policies
- Analyze device telemetry and network metrics to diagnose fleet connectivity anomalies across hardware and RF environments
- Collaborate with Hardware, Product, and Infrastructure teams on power-aware connectivity solutions for extreme conditions
- Debug real-world RF edge cases and deploy firmware directly to physical camera fleets
- Optimize cellular performance while managing battery constraints for edge deployment
What they're looking for
- AOSP internals and low-level Android OS architecture
- Cellular networking stacks (LTE, 5G modems, RIL, AT commands)
- SELinux security policies and permissions management
- TCP/IP, routing protocols, Wi-Fi architectures, and data optimization
- Embedded systems and OS-level development
- Qualcomm chipsets and cellular telemetry analysis
- Device driver development and kernel debugging
- C/C++ and Linux systems programming
Benefits
- Stock options
- Competitive base salary aligned with experience and market rates
- Remote work opportunity (USA-based)
