Software Engineer III, Device Connectivity

The Problem As Flock scales our 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. You will engineer our OS connectivity stack, optimize cellular performance, and ensure our edge cameras maintain rock-solid network connections in challenging field environments. What You'll Own 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. What This Role is Not This isn't an Android mobile application or UI development role, you will work entirely on low-level AOSP, cellular stacks, modems, and embedded Linux internals. This is not a purely theoretical networking position, you will analyze physical device telemetry logs, debug real-world RF edge cases, and deploy code directly to physical camera fleets. This isn't a siloed backend function, you will collaborate constantly across Hardware, Cloud, and Field Operations teams to streamline device connectivity workflows. What You Bring 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. Experience with Qualcomm chipsets, software tools, or cellular telemetry logs is a plus. Compensation In this role, you'll receive a starting salary between $130,000 and $160,000 as well as Flock Stock Options. Base salary is determined by job-related experience, education/training, as well as market indicators. Your recruiter will discuss this in depth with you during our first chat. Why Flock Every community deserves to be safe. Flock builds the technology that makes that real: last year we supported over 1 million criminal investigations and helped locate more than 10,000 missing people. We're 1,700 people building the impossible with over $1B in funding, and the expectations are high on purpose. If you want a role where the stakes are real and the pace matches, this is it. Some problems get solved faster in the same room, so we prioritize candidates in Atlanta and Boston. Hub-based roles mean real in-person time with your coworkers. Remote roles exist, and when a posting is open to remote work, it says so. Building the impossible takes every kind of mind. Flock is an equal opportunity employer, and we know the best solutions come from diverse perspectives, experiences, and skills working together with mutual respect. Everyone is welcome to apply.
