Senior Software Engineer II

Samsara is a company focused on connected operations and Internet of Things data solutions for organizations in physical industries. The Senior Software Engineer II will lead the In-Vehicle Experience team’s technical direction, building and shipping AI voice agent experiences for drivers and developing the full-stack systems that coordinate, evaluate, and evolve those experiences.

Responsibilities:

• Define what to build and how to build it, shaping product direction from the engineering side
• Build and ship voice agent experiences from zero to one in a fast-moving, ambiguous environment. Iterate quickly based on real interactions
• Own the technical direction for how these experiences coordinate: how they share context, how concurrent interactions get arbitrated, how the system holds up as more experiences are added, and how its real-time decisions can be investigated by the teams that need to
• Make and document architectural tradeoffs where requirements are still evolving, favoring foundations that generalize as new use cases emerge over one-off solutions that don't
• Serve as the team's technical anchor: review designs, unblock decisions, and mentor engineers as they expand into unfamiliar technical domains
• Introduce new patterns for full-stack and AI-assisted engineering, and get the team using them
• 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

Requirements:

• 8+ years of professional software engineering experience, including ownership of products from concept through production
• Bachelor's Degree in Computer Science, Engineering, or equivalent practical experience
• Recent, primary experience shipping LLM/agent based products end-to-end, including evaluation of AI behavior in production
• Experience with memory, context, or retrieval systems for AI applications (e.g., RAG pipelines, vector databases, long-lived session context)
• Strong programming and design fundamentals (Go, TypeScript, Python)
• Experience designing APIs and service boundaries that other systems rely on
• Experience setting technical direction on a team and mentoring other engineers
• Strong communication skills and the ability to influence technical direction without formal authority
• Located in and authorized to work in the United States or Canada (this is a fully remote role)
• Experience building zero-to-one products in fast-moving, high-autonomy environments
• Experience building persistent memory or personalization systems where agents learn about users over time
• Experience with multi-agent orchestration: coordinating multiple agents, avoiding conflicts, and maintaining consistency
• Experience building scheduling or arbitration systems
• Experience designing systems that combine structured and open-ended signal collection to inform product decisions
