Every community deserves to be safe, it’s a fundamental right. Our mission is simple - to build technology that reduces crime and protects privacy. Flock partners with cities, businesses, schools, and neighborhoods to help protect where people live, work, and play. Last year, Flock technology supported over 1 million criminal investigations. We've also helped solve approximately 20% of reported crimes in areas where we're deployed, and have played a role in locating more than 10,000 missing people.
We are a high-performance team united by urgency, ownership, and a shared commitment to meaningful impact. The work is fast-paced and the expectations are high. We push beyond perceived limits, support each other, and hold ourselves accountable to delivering results that matter.
With over $1B in funding and an $8.3B valuation, we are scaling with intention and investing in the people who will help us build what others said could not be done. At Flock, you will find the opportunity to grow quickly, take on real responsibility, and contribute to something bigger than yourself.
As a member of the Device Engineering team at Flock, you will specialize in the critical domain of device connectivity. We are looking for a Software Engineer III - Device Connectivity to advance our modern Android-based system stack, with a direct focus on fleet stability and driving our 5G upgrade roadmap. You will ensure our edge devices maintain a rock-solid network connection in challenging, real-world outdoor environments while optimizing power consumption to maximize battery life. This role requires a unique blend of embedded Android internals, a deep understanding of cellular networking technologies, and a high-ownership approach to solving complex fleet problems at scale.
A Bachelor's, Master’s, or Ph.D. in Computer Science, Computer Engineering, Electrical Engineering, or a related field with 3+ years of experience in embedded systems or OS-level development.
Deep expertise in low-level Android OS architectures (AOSP/Custom ROMs), specifically handling system initialization (init processes), image partitioning, and file systems.
Strong practical knowledge of SELinux security policies, permissions management, and debugging system access restrictions.
Hands-on experience with the cellular connectivity stack, including LTE/5G modems, Radio Interface Layer (RIL), AT commands, and SIM/eSIM management.
A proven ability to debug complex, system-level issues across hardware boundaries, kernel drivers, and Android user-space applications.
Strong proficiency in networking technologies, including TCP/IP protocols, routing tables, Wi-Fi, and data optimization.
Specific experience with Qualcomm chipsets and their associated software tools is highly preferred.
A systems-thinking approach to problem-solving, analyzing how RF environments, power constraints, and thermal conditions impact device performance.
Fluency in telemetry and data analysis, with the ability to interpret logs and network metrics to drive data-informed engineering decisions.
Strong cross-functional collaboration skills, with experience working closely with Hardware, Product, and Cloud/Infrastructure teams to triage fleet anomalies.
Effective verbal and written communication skills, humility, curiosity, and a passion for sharing knowledge.
