Firmware Intern - MCU

About the role:

Samsara’s cloud-connected sensor platform collects observations about the world in near real-time. Samsara builds an extensive set of products, including battery-powered, wireless sensors, Linux-based IoT gateways, and Internet-connected dashcams. These devices are the building blocks Samsara uses to construct enterprise solutions for a wide range of verticals, including commercial fleet management and industrial monitoring. Through a unique integration of sensor data such as GPS, acceleration, temperature, video, and more, we enable our customers to gain greater insights into operations, identify and eliminate inefficiencies, and react to alerts all in near real-time.

As a firmware engineering intern-MCU at Samsara, you will develop software that runs on millions of devices, deployed by our industrial and enterprise customers. You’ll tackle challenges including evaluating and selecting hardware components, bringing up new hardware platforms and sensors, building systems to gather data and detect meaningful events, and structuring recorded data to allow efficient analysis across thousands of devices while providing deep insights into individual events.

This is a hybrid position requiring 3 days per week in our San Francisco, CA headquarters office and 2 days working remotely.  Relocation and housing assistance will be included as part of the co-op. 

You should apply if:

• You want to impact the industries that run our world: Your efforts will result in real-world impact—helping to keep the lights on, get food into grocery stores, reduce emissions, and most importantly, ensure workers return home safely.
• You are the architect of your own career: If you put in the work, this role won’t be your last at Samsara. We set up our employees for success and have built a culture that encourages rapid career development, countless opportunities to experiment and master your craft in a hyper-growth environment.
• You’re energized by our opportunity: The vision we have to digitize large sectors of the global economy requires your full focus and best efforts to bring forth creative, ambitious ideas for our customers.
• You want to be with the best: At Samsara, we win together, celebrate together and support each other. You will be surrounded by a high-caliber team that will encourage you to do your best. 

In this role, you will: 

• Collaborate with other firmware engineers on the team to design, develop, and maintain embedded software for our gateway and sensor products
• Bring up new hardware platforms: configuring I/O, debugging interfaces such as SPI, I2C, UART, CAN, and ADC, testing connectivity, validating design and debugging system initialization
• Implement peripheral drivers, secure bootloaders and device firmware updates, and core management layers (power manager, connectivity manager, etc)
• Design protocols and implement efficient hardware management to optimize energy consumption of battery-powered sensors and gateways
• Work cross-functionally with different stakeholders across product, full-stack, and quality teams to deliver reliable high high-quality embedded software
• Gain hands-on experience in a fast-paced and innovative environment
• Get valuable mentorship and guidance from experienced firmware engineers
• Be exposed to the entire product development lifecycle, from concept to deployment
• Champion, role model, and embed Samsara’s cultural principles (Focus on Customer Success, Build for the Long Term, Adopt a Growth Mindset, Be Inclusive, Win as a Team) as we scale globally and across new offices

Required requirements for the role:

• Enrolled in a Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or related field with a graduation timeline of May-June 2026.
• Must have solid C programming skills
• Familiarity with embedded programming concepts
• Prior experience with MCU development environments and tools (Segger J-Link, GCC)
• Experience working in bare metal and RTOS-based systems such as Zephyr and/or FreeRTOS
• Experience in one or more core technologies such as BLE, GPS, LTE and CAN
• Strong problem-solving skills and an analytical mindset to debug and optimize code.
• Be excited about sensors, connectivity protocols, distributed systems, and their application to solve real world problems
• Thrive in an environment that requires rapid deployment and product iteration based on customer feedback while focusing on automated testing and code quality
• Any prior projects, coursework, or personal projects related to embedded systems and firmware development would be advantageous.
