Principal Software Engineer (Avigilon Access Control)

• Motorola Solutions Inc. (MSI) is seeking an experienced Principal Software Development Engineer to lead the evolution and optimization of our high-scale Access Control solution. This role will drive the multi-year technical vision and execution strategy for how our systems manage, synchronize, and authorize real-time security identities, permissions, and event telemetry across a global footprint. This role bridges high-performance cloud-native microservices and intelligent, resource-constrained edge hardware
• Our enterprise customers from emerging businesses to global, highly regulated enterprises depend on absolute reliability, security, and real-time responsiveness to protect their people, property, and physical spaces. Our access control solution processes millions of security events and device status updates daily, putting critical data and operational control directly into the hands of security operators around the world
• The architectures you design will directly determine optimization of our cloud and on-premises solutions, and how elegantly our systems maintain absolute resilience at the physical edge
• Our edge-to-cloud security ecosystem operates in a hybrid model where sub-second latency is non-negotiable for real-time entry decisions, yet absolute consistency and transactional safety are required for access logs, identity synchronization, and emergency lockdowns
• As we evolve our systems to support enterprise-scale multi-tenancy, high-volume device telemetry, and AI-native edge capabilities, we require fundamentally new approaches to how we partition configurations, cache credentials, and orchestrate security states across the network. You will pioneer architectures where performance, security-by-design, and operational simplicity emerge naturally from sound, cohesive engineering rather than brute-force scaling or ad-hoc, matrixed integrations
• Define Technical Strategy and Vision: Own the multi-year technical roadmap and architectural vision for enterprise scale physical access control solution, translating complex, ambiguous business initiatives into simple, scalable, and maintainable distributed systems
• Architect Edge-to-Cloud Resilience: Design and optimize high-performance, low-latency architectures that securely connect cloud-native microservices with physical edge devices, establishing absolute local system resilience and offline-first capabilities
• Drive Cross-Team Collaboration and Mentorship: Serve as a technical force multiplier by leading high-stakes architectural design reviews, building technical consensus across distributed engineering teams, and mentoring senior technical talent
• Innovate with Next-Generation Capabilities: Research, prototype, and architect emerging platform capabilities, including edge computing optimizations, secure distributed credential frameworks, and intelligent system interfaces to maintain a highly competitive technology stack
• Cross-Organizational Leadership and operational excellence: Build consensus across multiple engineering organizations with different priorities. Lead architectural reviews and provide critical, constructive feedback. Foster a culture of engineering excellence through code, designs, and technical standards

• Expertise in query optimization, execution planning, and distributed transaction databases
• Direct technical experience with Physical Access Control Systems, embedded device firmware, real-time operating systems (RTOS), or video security integrations
• Proven success in taking a large, mature, legacy codebase and successfully decomposing it into clean, testable, and highly autonomous bounded contexts
• A track record of mentoring senior engineering talent to Staff/Principal level
• Recognized thought leadership, patents, or publications in distributed systems, IoT security, or edge computing
• Experience establishing and maintaining automated continuous integration and continuous delivery (CI/CD) pipelines down to the physical hardware edge to replace manual deployment validation
