• 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:

• Build and Deliver Mobile Features: Design, implement, and ship high-quality, performant, and user-friendly mobile application features using React Native.
• Contribute to Shared Systems: Develop reusable components and frameworks that serve as building blocks across multiple teams and applications in the mobile ecosystem.
• Improve Developer Experience: Contribute to the health and maintainability of our CI pipelines, build tools, and monitoring systems to support developer productivity and mobile release stability.
• Collaborate Across Teams: Work closely with product managers, designers, and engineers to understand requirements and translate them into scalable mobile solutions.
• Uphold Code Quality: Write clean, maintainable code with thoughtful test coverage and participate in code reviews that raise the bar for mobile engineering.
• Grow and Learn: Continuously develop your technical skills, while being open to mentorship and feedback in a collaborative, high-trust environment.
• 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:

• 2+ years of professional software engineering experience, including experience building production web or mobile applications.
• Proficiency in JavaScript/TypeScript and experience with React Native or React in a production environment.
• Familiarity with common patterns in mobile architecture, state management (e.g., Redux or similar), and API integration.
• Strong understanding of fundamental software engineering principles: testing, version control, code reviews, debugging.
• Collaborative mindset and experience working on a team to build customer-facing products.
• A desire to grow as an engineer and contribute to a supportive and high-performing team.

An ideal candidate also has:

• Experience working in a mobile-focused environment, contributing to apps used at scale.
• Exposure to monitoring, logging, or performance tooling to improve app health and reliability.
• Interest in building for real-world users like drivers, field workers, or logistics teams.
• Familiarity with accessibility best practices and UI design principles.
• Curiosity around full-stack systems and how mobile clients interact with backend services.
