Senior Software Engineer II, Smart Trailer & Connected Equipment

About the role:

The Smart Trailers team leads the development of critical product lines at Samsara, including advanced sensors and trailer technology. We are moving beyond simple tracking to build a comprehensive operating system for our customers' freight and logistics ecosystem.

As a Full Stack Engineer on this team, you will build the technical foundation that powers the world's most complex fleets. Your work will focus on solving critical logistics challenges, such as protecting trailers and cargo from loss or theft. You will design intelligent systems utilizing geofencing and motion data to distinguish between authorized departures and potential security breaches for critical assets sitting in depots or moving across the country.

Simultaneously, you will build algorithms to boost asset utilization, helping customers reduce wasted fuel, empty miles, and unnecessary maintenance. You will also play a key role in safeguarding sensitive cargo operations. Whether our customers are transporting temperature-controlled goods, hazardous materials, or high-value industrial equipment, you will build the infrastructure that monitors environmental conditions to ensure load integrity and regulatory compliance.

As the product evolves, you will expand these core capabilities by integrating computer vision to automate yard checks and developing new layers of supply chain visibility to track inventory and orders alongside the physical assets.

This role is remote and open to candidates residing in the US.Relocation assistance will not be provided for this role.

You should apply if:

• You want to impact the industries that run our world: The software, firmware, and hardware you build will result in real-world impact—helping to keep the lights on, get food into grocery stores, and most importantly, ensure workers return home safely.
• You want to build for scale: With over 2.3 million IoT devices deployed to our global customers, you will work on a range of new and mature technologies driving scalable innovation for customers across industries driving the world's physical operations.
• You are a life-long learner: We have ambitious goals. Every Samsarian has a growth mindset as we work with a wide range of technologies, challenges, and customers that push us to learn on the go.
• You believe customers are more than a number: Samsara engineers enjoy a rare closeness to the end user and you will have the opportunity to participate in customer interviews, collaborate with customer success and product managers, and use metrics to ensure our work is translating into better customer outcomes.
• You are a team player: Working on our Samsara Engineering teams requires a mix of independent effort and collaboration. Motivated by our mission, we’re all racing toward our connected operations vision, and we intend to win—together.

In this role, you will:

• Bring a customer-focused mindset to all development, balancing the need to iterate quickly and deliver customer wins iteratively
• Partner with the Engineering Manager to advocate for long-term technical health of our products alongside product priorities.
• Act as a force multiplier on the team by leveraging other engineers and personally exemplify how to deliver value at Samsara
• Mentor other engineers by actively participating in design and implementation conversations across the team
• 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.

• 8+ years of relevant industry experience in software development.
• Strong programming/coding fundamentals with proficiency in at least one of the following: Go, GraphQL, TypeScript, React.
• Excellent communication, collaboration, and problem-solving skills, with a demonstrated ability to manage technical discussions.
• Data Visualization Skills: Experience building frontend interfaces that make complex data (utilization rates, equipment status) digestible and actionable for users.

An ideal candidate also has:

• Geospatial & Time-Series Data Experience: Proven ability to work with map-based data (geofences, lat/long coordinates) and time-series sensor data.
• Experience with Computer Vision/ML Integration: While you don't need to be an ML Engineer, you have experience consuming ML model outputs (e.g., from camera feeds) and integrating them into user-facing applications.
• Big Data Analytics: Familiarity with data warehousing or processing frameworks to derive insights from trillions of data points.
• Logistics or Supply Chain Domain Knowledge: Understanding of concepts like cargo compliance, yard management, or freight workflows.
• Zero-to-One Mindset: Experience building and shipping a product from scratch and scaling it for growth and business impact.
