Sr. Automation Engineer (Infra)

About the role:

Samsaras Automation team enables fast high-quality software releases by building reliable test tools and frameworks identifying opportunities to improve developer experience and engaging cross-functionally to resolve key this role a successful candidate will help build our Automation Test Framework. This key role will enable teams to ship high-quality products ship firmware updates to our customers faster and facilitate quality investigations.

This position may be Remote-US. If remote occasional travel may be required on a quarterly basis.

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 worlds 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 were all racing toward our connected operations vision and we intend to win together.

In this role you will:

• Own Automation as a Product: Define and drive high-impact end-to-end automation solutions. You dont just facilitate testing; you architect the bridge between hardware development and rapid software delivery across the entire product lifecycle.
• Drive Technical Vision & Delivery: Act as the technical North Star for the team. You take full accountability for the end-to-end delivery of complex automation solutions while elevating the collective bar through intentional mentoring and technical leadership.
• Identify & Build Opportunities: Proactively partner with Firmware and QE to uncover bottlenecks in the developer experience. You dont wait for requirements; you identify friction points in testing speed and quality and build solutions to eliminate them.
• Architect for the Future: Design and scale robust software frameworks capable of handling the rigorous reliability and performance demands of a global device fleet.
• Optimize Workflows with AI: Pioneer the integration of AI tools and intelligent automation to streamline development and testing workflows significantly reducing manual overhead and accelerating the feedback loop for our engineers.
• Bridge the Hardware-Software Gap: Develop sophisticated software that turns physical hardware infrastructure into a seamless scalable automation utility. You will integrate simulation and validation tools that support both current products and unreleased next-generation designs.
• Drive Organizational Adoption: Act as an internal evangelist for your tools. You ensure long-term success not just by shipping code but by conducting high-value demos tutorials and proof-of-concepts that prove the frameworks value to Firmware and QE users.
• Engineer Realistic Simulation: Create high-fidelity simulation environments that unlock platform-wide functional testing before hardware even reaches the bench.
• Solve for the Why: Create measurable impact by developing deep empathy for your internal customers. You identify their core pain points and move beyond bug fixing to recommend and implement strategic long-term solutions.
• Champion role model and embed Samsaras 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 of experience developing software bonus points for emphasis on testing/software tools for product development and validation.
• Understanding of tradeoffs between efficiency scalability and performance.
• Extensive experience in code reviews especially cross-functional/cross-discipline.
• 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.
• Experience working and developing within a Linux environment.

An ideal candidate also has:

• A Product & Owner Mindset: You are obsessed with the why. You possess deep customer empathy take full accountability for end-to-end outcomes and proactively adapt based on feedback to ensure long-term success.
• Infrastructure Architect Experience: Proven track record of building and scaling automation and HIL testing frameworks from the ground up.
• Hardware & Wireless Expertise: Hands-on experience testing embedded systems with CAN interfaces and wireless protocols like BLE WiFi LTE and GNSS.
• Data-Driven Leadership: Expert in defining test strategies triaging complex failures and leveraging Python and data tools (e.g. SQL Pandas Databricks) to turn raw metrics into actionable insights.
• Workflow Optimization: A proactive approach to streamlining development cycles including the ability to leverage AI tools to automate manual overhead and accelerate feedback
