Job Details

Description

SmartSense builds end-to-end IoT systems for industries where accuracy and uptime matter — healthcare, food safety, life sciences, and supply chain. Our platform combines wireless sensors, intelligent gateways, and always-on cloud connectivity to deliver mission-critical insights at scale. More than 2,000 organizations trust SmartSense for reliable, real-time data in environments where failure isn’t an option.

What We Offer

If you enjoy working across hardware, firmware, wireless networks, and edge computing, this role is the right mix of technical depth and real-world impact. You’ll help design next-generation architectures while also improving the reliability and performance of thousands of deployed devices. You’ll work alongside engineers who enjoy digging into data, exploring new ideas, and building systems that actually matter. It’s a chance to work on a complex IoT stack while having fun doing it.

What You Will Do

• Build and maintain embedded firmware (C/C++) for sensors and gateways powering SmartSense’s IoT ecosystem.
• Own critical parts of the firmware stack — from low-power drivers to real-time telemetry pipelines.
• Analyze and solve field issues across a massive distributed fleet, using telemetry, logs, and real hardware debugging tools.
• Develop firmware updates that introduce new capabilities, improve performance, or support evolving hardware.
• Tune wireless performance (BLE, Zigbee, LTE, GPS) and optimize power consumption for long-life sensors.
• Contribute to next-gen platform architecture, including edge processing and smarter sensor workloads.
• Bring up new hardware platforms — sensors, radios, boards — and collaborate with hardware engineers on system validation.
• Prototype new ideas, test their limits, and iterate quickly.
• Strengthen system diagnostics so the devices tell us what’s happening before anything becomes a problem.
• Support field engineering, manufacturing, and operations with tools, scripts, and deployment workflows.

Who You Are and What You Bring

• 5+ years building firmware for embedded systems or IoT devices.
• Deep experience in C/C++, RTOS development, drivers, peripherals, power management, and system-level thinking.
• Strong understanding of IoT wireless technologies including BLE, Zigbee, LTE, GPS, and mesh-like networks.
• Comfortable maintaining legacy systems while also designing cleaner, modern solutions.
• You enjoy debugging — logic analyzers, scopes, JTAG, weird edge cases, intermittent failures — all of it.
• Experience with RTOS or embedded Linux (Yocto, Ubuntu).
• Clear communicator who enjoys collaborating with hardware, cloud, and product teams.
• Based in the Greater Boston area for hybrid onsite work.
• Experience with AWS IoT, Azure IoT, or Google Cloud IoT is strongly preferred.

Desired But Not Required

• Experience with Digi XBee modules or mesh networking.
• Interest in TinyML, edge inference, or embedded analytics.
• Background in ultra-low-power design.
• Experience working in regulated or compliance-driven environments.
• Please note that we are unable to provide visa sponsorship for this position. This includes, but is not limited to, work visas, employment-based visas, or residency sponsorship. Candidates must have valid work authorization in the United States at the time of application. Visa applications of any kind will not be considered.
