Motivated by our mission, we’re all racing toward our connected operations vision, and we intend to win—together. In this role, you will: ML Platform & Infrastructure Design, build, and operate Samsara’s end-to-end ML platform (training, experimentation, batch/online inference, edge) used by multiple Safety AI product teams. Evolve shared training and experimentation infrastructure (orchestration, clusters, environments) and standardize tracking, evaluation, and regression testing for fast, safe iteration. Experimentation & Measurement Partner with product and applied ML teams to ship ML-powered features (CV models, EcoDriving insights, LLM-based reporting) that improve safety, reliability, and cost efficiency. Lead throughput and cost modeling for new ML features—from exploration to production-scale capacity planning—to inform roadmap and go/no-go decisions. Drive experiment design and evaluation , defining success metrics, structuring A/B or offline tests, and turning results into product and technical decisions. Inference & Edge Deployment Design and operate scalable online and batch inference systems (Ray, Spark), including deployment patterns, observability, SLOs, and unified training-to-production workflows. Partner with firmware and edge teams to package, validate, and deploy models to Samsara devices , and build feedback loops from edge to cloud for continuous improvement. Reliability, Security & Operations Own reliability, observability, and security for ML systems across cloud and edge, including on-call practices, incident response, and infrastructure hardening. Own or co-own end-to-end technical delivery for high-priority or high-risk initiatives, from modeling and system design through production rollout. Leadership & Culture Provide Staff+/Senior-Staff technical leadership on ML infrastructure architecture and strategy, influencing cross-team decisions and mentoring engineers and applied scientists. Drive strong developer experience through documentation, office hours, and best practices, while contributing to and representing Samsara in open source communities (Ray, Spark, RayDP). Champion and role model Samsara’s cultural principles: Focus on Customer Success, Build for the Long Term, Adopt a Growth Mindset, Be Inclusive, Win as a Team . Minimum
