Software Engineer III, Device Connectivity

Flock

3d•$130,000 - $160,000•Onsite

About The Position

As Flock scales its edge device infrastructure across diverse outdoor environments, maintaining uninterrupted cellular connectivity and long-term fleet stability is vital to real-time operations. Transitioning our custom Android system stack through a 5G upgrade roadmap while managing strict battery power constraints requires specialized embedded systems expertise. This role will engineer the OS connectivity stack, optimize cellular performance, and ensure edge cameras maintain rock-solid network connections in challenging field environments.

Requirements

Practical experience in embedded systems or OS-level development, with deep knowledge of low-level Android OS architectures and AOSP internals.
Hands-on expertise with cellular networking stacks, including LTE/5G modems, Radio Interface Layer integrations, AT commands, and SIM/eSIM management.
Technical understanding of SELinux security policies, permissions management, and debugging system access restrictions.
Proficiency in networking protocols including TCP/IP, routing tables, Wi-Fi architectures, and data optimization techniques.
A bachelor's, master's, or Ph.D. degree in computer science, computer engineering, electrical engineering, or a related technical field is required.

Nice To Haves

Experience with Qualcomm chipsets, software tools, or cellular telemetry logs is a plus.

Responsibilities

Advance our modern Android-based system stack with a direct focus on cellular connectivity, fleet stability, and the 5G upgrade roadmap.
Engineer low-level AOSP system initialization routines, image partitioning, file system structures, and SELinux access policies.
Optimize cellular stack integrations spanning LTE and 5G modems, Radio Interface Layer components, AT commands, and eSIM configurations.
Analyze device telemetry and network metrics to diagnose complex fleet anomalies across hardware boundaries, RF environments, and user space.
Partner cross-functionally with Hardware, Product, and Infrastructure teams to design power-aware connectivity states for extreme seasonal conditions.
