Senior Software Engineer, Fleet Safety

About the role:

At Samsara, driver safety is at the heart of fleet management. With more vehicles on the road than ever, the need for smarter, proactive safety solutions is critical. The Safety Applications team builds cutting-edge, AI-powered coaching products across web, mobile, and API surfaces, working closely with ML and AI engineering teams to deliver impact at scale.

Our products promote safer and more efficient driving by providing targeted, actionable feedback. Managers and supervisors (coaches) can help drivers recognize and correct risky behaviors—such as harsh braking, speeding, mobile usage, excessive idling, or Hours of Service (HOS) violations—reducing the likelihood of future incidents. Through the Samsara dashboard, coaches can share events directly with drivers to enable meaningful coaching, follow-up, and improvement.

As a Senior Engineer on the team, you will collaborate with Product and Design to evolve and expand our coaching products, refine workflows based on customer feedback, and deliver scalable, AI-driven solutions that make global operations safer, smarter, and more efficient.

This is a remote position open to candidates residing in the US.

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:

• Solve complex problems and own the success of your solutions as you architect, build, test, and deliver full-stack products
• Consistently produces high-quality, scalable, and maintainable code, and is able to turn ambiguous problems into clear, actionable work.
• Takes full ownership of complex technical domains and drives them end-to-end with minimal oversight.
• Demonstrates deep understanding of system architecture, makes strong technical decisions, and proactively surfaces technical debt along with proposed solutions.
• Shows strong ownership by focusing on outcomes rather than tasks and makes thoughtful trade-offs between speed, quality, and customer value.
• Integrate large language models (LLMs) into safety workflows, design and run evaluations, and build feedback loops that continuously improve the accuracy, precision, and reliability of the insights delivered to safety managers.
• Communicates effectively with engineers, PMs, designers, and cross-functional teams—aligning stakeholders, clarifying priorities, and managing expectations.
• Influences team direction through data, customer insight, and sound technical judgment, contributing impact beyond individual tasks at the team level.
• Own the operational health of production systems as we build for the future scale of an ever-growing customer base.
• Make an impact on our core architecture, roadmap, and the wider engineering community.
• Mentors junior and mid-level engineers through guidance, constructive code reviews, and by promoting strong engineering culture and best practices.
• 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

Minimum requirements for the role:

• 5+ years of experience in software development
• Experience shipping features that are used by customers and iterate on customer feedback to inform what to deliver next
• Strong communication skills and a desire to collaborate. You can explain why you build something a certain way and be open to suggestions from other engineers and stakeholders
• A growth mindset and excitement around building new skills and expertise
• Should be a quick learner and operate with minimum supervision
• Comfortable with building out end-to-end solutions. A preference for front-end or back-end development is okay, but you’ll need to be happy working across the stack
• Familiarity with integrating LLMs into products, including running evaluations and creating feedback loops to improve accuracy and usefulness of generated insights.
• Assist in maintaining the production systems your team owns and provide operational support when necessary
• Utilize logs and metrics for tracking down and investigating bugs, ensuring the robustness and reliability of our systems

An ideal candidate also has:

• 5+ years of full-stack experience working in a fast-paced environment and contributing to an early-stage product
• Experience with taking LLM systems to production
• Effectively collaborated on a geographically distributed team
• Maintain software products at scale
• Experience in Go, GraphQL, Typescript, React, and AWS is a plus
