We’re a small, close-knit group of roughly 20 people, each of us experts in our fields, working to bring autonomous vehicles to various industries quickly. We believe this moment in robotics and autonomy is as groundbreaking as the PC industry of the 80s, and we need your help. About the role Overview: Polymath Robotics is creating software that can safely control all of the world's industrial vehicles, and we’re looking for a Network Engineer/DevOps person to join our team. We’re a small, close-knit group of roughly 20 people, each of us experts in our fields, working to bring autonomous vehicles to various industries quickly. We believe robotics and autonomy are at a tipping point, similar to how the PC industry reshaped the world in the 80s, and we need your help. Polymath Robotics is creating software that safely controls industrial vehicles. As our Senior Infrastructure Engineer, you’ll architect and scale the backbone of that system — defining what services we use, how they interconnect, and how they scale across fleets. You’ll work closely with our software and robotics teams to ensure reliability and performance across our distributed systems. Responsibilities: Design, implement, and maintain core infrastructure services powering our robot fleet and backend systems. Define how systems communicate, authenticate, and scale between cloud and edge. Own observability infrastructure (e.g., Prometheus, Grafana, Loki) — metrics, logging, alerting, uptime. Develop and optimize data storage and querying solutions (PostgreSQL, rosbags/mcap). Create robust strategies for backup, recovery, and disaster resilience. Develop and optimize binary/artifact stores for rapid delivery to robots. Collaborate with robotics and application teams to ensure infrastructure scales with product growth. Drive architectural decisions for reliability, maintainability, and cost efficiency. Mentor team members in good software and systems engineering practices. Qualifications: 5+ years of experience building and scaling production infrastructure systems. Proven track record with distributed systems, containers (Kubernetes/Podman), and cloud infrastructure. Deep knowledge of Prometheus, PostgreSQL, and data pipeline design. Experience integrating observability and monitoring into CI/CD workflows. Strong coding and automation skills (Python, Go, Bash, or equivalent). Solid grasp of security, networking, and service interconnect patterns. Self-directed, high-ownership mindset. Why Join Polymath Robotics? Collaborative Environment: Work alongside fantastic team members on collaborative projects Hybrid Workplace: Enjoy the flexibility of a hybrid work model, with engineering based in our SF Mission office three days a week, giving a good balance of maker time and synchronization time. Open Source Advocacy: We strongly support open-source robotics efforts, allowing your work to be shareable and publishable whenever possible. Humor & Passion: We might occasionally be a bunch of rosbags, but our passion and humor drive us to accelerate the realization of autonomous vehicles in the industry. Application Process: Interested candidates are invited to submit their resume, and any relevant portfolio or project links. A cover letter is optional, but always appreciated. Polymath Robotics is an equal-opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. We don’t look for a “cultural fit”, we look for people who add to the culture.
