• 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:

• Develop an end-to-end automation strategy to facilitate testing activities throughout Samsara product life cycles.
• Communicate with the development engineers to gather system requirements.
• Architect and design software frameworks to meet the reliability, scalability, and performance requirements of our products.
• Develop software to enable automation tools across Samsara’s current product portfolio and future designs. Integrate hardware infrastructure for simulation, hardware validation, and product development.
• Collaborate with software developers, firmware and QE to ensure seamless integration of framework into applications.
• Create simulation environments to enable testing and data collection of all platform functionalities.
• Develop a visualization solution for framework outputs including test results and real-time performance.
• 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:

• Five years experience building automated test frameworks and software tools for product development and validation.
• Understanding of framework architectures and tradeoffs between efficiency, scalability, and performance.
• Software development experience.
• Participation in code reviews for Product/Feature code changes across all SWE departments.
• Mastery of core libraries used within automation frameworks.
• Experience creating and implementing hardware-in-the-loop simulation.
• Technical understanding of communication protocols (TCP, UART, and wireless).
• Ability to design and develop hardware infrastructure for test applications. (e.g. power measurement tools, RF testing, etc.).
• Experience with test instrumentation including the use of power supplies, power analyzers, battery simulators, call boxes, and GPS simulators.

An ideal candidate also has:

• Experience building and maintaining automation testing infrastructure from the ground up.
• Experience testing devices with wireless protocols including BLE, WiFi, LTE, and GNSS.
• Experience interfacing with embedded systems’ command line interfaces and AT commands.
• Experience defining test plans, triaging test failures and reporting result data and relevant metrics.
• Experience with data analysis tools/packages such as SQL, Pandas, databricks, etc.
