SimpliSafe
Overview
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. We’ve created a culture that cares about the career you’re building. Our no ego culture emphasizes collaboration and innovation, where those seeking their next challenge can find big opportunities and make a huge impact. 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 coming together in our state-of-the-art office on two core days, typically Tuesday and Wednesday, and teams can choose where they work for the remainder of the week. Why are we hiring? We’re growing and thriving. 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. What You’ll Do As a Senior Embedded Software Engineer specializing in Wireless Networking, you will focus on optimizing SimpliSafe’s wireless communications systems to improve performance, resilience, and power. You will contribute to product development, focusing on IoT device connectivity. The role requires a profound understanding of the wireless radio and communication stacks, and the entire networking stack from the physical layer up to the application. You will debug complex issues and optimize every layer of the network stack to achieve performance, reliability, and power efficiency in our IoT and camera devices. This is a hands-on role where you will work with firmware, analyze network traffic, and collaborate with hardware, software, QA, and cloud teams to deliver robust wireless solutions. Responsibilities
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) through TCP/IP 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 performance, power, and memory constraints of embedded systems. Performance Analysis:
Conduct in-depth analysis of wireless and networking stacks, identify bottlenecks, and propose solutions (e.g., retransmission strategies, buffer management, concurrency, power management, scheduling). Root Cause Analysis:
Perform detailed root cause analysis of intermittent networking issues using advanced debugging techniques and tools. Cross-Functional Collaboration:
Work with hardware engineers to characterize RF performance, integrate drivers, and troubleshoot hardware-firmware interactions; collaborate with application software to ensure seamless integration of network services. Testing & Validation:
Define and help develop comprehensive test plans for wireless systems with QA and Automation teams, including unit, integration, and system-level tests. Stay Current:
Keep abreast of the latest advancements in wireless technologies, networking protocols, and embedded systems. Travel:
Willing to travel to Asian manufacturing partners 1-3 times per year. Required Skills & Experience
Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field. 5+ years of experience in embedded firmware development with a strong focus on wireless networking. Expert-level proficiency in C/C++ for embedded systems. Deep understanding of the entire TCP/IP networking stack (Layers 2-7), including Ethernet, IP, TCP, UDP, DNS, DHCP, Thread, etc. Extensive experience with WiFi (802.11) protocols, including MAC layer operations, roaming, power saving modes, and coexistence. Hands-on experience with embedded operating systems including FreeRTOS and Linux. Experience with various microcontrollers (e.g., ARM Cortex-M/R) and their peripherals. Proven ability to optimize embedded networking stacks for throughput, latency, power consumption, and memory footprint. Strong understanding of network security concepts, protocols, certificates/keys, firewalls, packet inspection and filtering. Familiarity with tools such as Wireshark, Communications Analyzer, traffic/load generators, network throttling, and wireless impairment test setups. Preferred Qualifications
Experience with Matter/Thread networking is a plus. Familiarity with cloud platforms (AWS IoT) and their connectivity requirements. What Values You’ll Share
Customer Obsessed Aim High No Ego One Team Lift As We Climb Lean & Nimble What We Offer
A mission- and values-driven culture and a safe, inclusive environment to build, grow and thrive. A comprehensive total rewards package to support wellness and security for employees and families. Free SimpliSafe system and professional monitoring for your home. Employee Resource Groups (ERGs) that foster networking, mentorship, and development. We wholeheartedly embrace applications from all individuals. We are committed to cultivating a diverse and inclusive workplace and value multiple perspectives and experiences. If a reasonable accommodation is needed to participate in the job application or interview process, to perform essential functions, or to receive benefits, please contact careers@simplisafe.com.
