What You'll Do
As a Principal Embedded Software Engineer specializing in Wireless Networking, you will focus on optimizing SimpliSafe’s wireless communications systems for performance, resilience, and power. You will be a critical contributor to product development, addressing the full networking stack from physical layer to application. You will debug complex issues and optimize every layer of the network stack for throughput, reliability, and power efficiency in our IoT and camera devices. This is a hands-on role involving firmware analysis, network traffic examination, and collaboration with hardware, software, QA, and cloud teams to deliver robust wireless solutions.
Responsibilities:
- Full Communications Stack Network Debugging & Optimization: Diagnose and resolve complex network issues across the stack (PHY/MAC through TCP/IP to the application) on embedded IoT devices.
- Protocol Implementation & Tuning: Implement, port, and optimize low-power wireless (802.11, HaLow, Thread) and TCP/IP protocols within embedded constraints.
- Performance Analysis: Analyze wireless and networking stacks to identify bottlenecks and propose optimizations (retransmission strategies, buffer management, concurrency, power management, scheduling).
- Root Cause Analysis: Conduct detailed debugging of intermittent networking issues using advanced tools.
- Cross-Functional Collaboration: Work with hardware engineers to characterize RF performance, integrate drivers, and troubleshoot hardware-firmware interactions; collaborate with application software teams for seamless integration.
- Testing & Validation: Define and help develop comprehensive test plans for unit, integration, and system-level tests with QA and Automation teams.
- Stay Current: Keep up with the latest wireless technologies and embedded systems developments.
- 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.
- 10+ years of embedded firmware development with a strong focus on wireless networking.
- Expert-level proficiency in C/C++ for embedded systems.
- Deep understanding of the 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 operations, roaming, power saving, 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, and traffic filtering.
- Familiarity with tools such as Wireshark, traffic generators, load generators, and impairment test setups.
Preferred Qualifications:
- Experience with Matter/Thread networking is a plus.
- Familiarity with cloud platforms (AWS IoT) and their connectivity requirements.
