Staff Embedded Software Engineer (Wireless Networking)

We’re a high-tech home security company that’s passionate about protecting the life you’ve built and our mission of keeping Every Home Secure. And we’ve created a culture here that cares just as deeply about the career you’re building. Ours is a no ego culture of collaboration and innovation where those seeking their next challenge can find big opportunities and make a huge impact on the lives of all those who we protect. We don’t just want you to work here. We want you to grow and thrive here.

We’re embracing a hybrid work model that enables our teams to split their time between office and home. Hybrid for us means we expect our teams to come together in our state-of-the-art office on two core days, typically Tuesday and Wednesday, to work together in person, and teams can choose where they work for the remainder of the week. We all benefit from flexibility and get to use the best of both worlds to get our work done.

Well, we’re growing and thriving. So, we need smart, talented, and humble people who share our values to join us as we disrupt the home security space and relentlessly pursue our mission of keeping Every Home Secure. 

• →Full Communications Stack Network Debugging & Optimization: Diagnose and resolve complex network connectivity, throughput, latency, and reliability issues across the entire networking stack, from the wireless radio (PHY/MAC layers) through TCP/IP and up to the application layer on embedded IoT devices.
• →Protocol Implementation & Tuning: Implement, port, and optimize low power wireless (802.11, HaLow, Thread) and TCP/IP protocols to meet specific performance, power, and memory constraints of embedded systems.
• →Performance Analysis: Conduct in-depth performance analysis of wireless and networking stacks, identifying bottlenecks and proposing innovative solutions for optimization (e.g., retransmission strategies, buffer management, concurrency, power management, scheduling).
• →Root Cause Analysis: Perform detailed root cause analysis of intermittent and hard-to-reproduce networking issues using advanced debugging techniques and tools.
