Senior Infrastructure Engineer - San Francisco

Qualifications

The ideal candidate has worn several of these hats before — not necessarily all of them, but more than one. Startup experience where you were handed problems outside your job title is a strong signal. Here's what we're looking for:

• Hands-on experience across multiple infrastructure disciplines: IT/sysadmin, cloud IaC, CI/CD, networking, or security
• Experience in a startup or small team where roles were fluid and you owned things end-to-end
• 3+ years in infrastructure, DevOps, IT engineering, or a closely related field
• 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.
• Solid grasp of security, networking, and service interconnect patterns.
• Strong automation instincts — if you've done something twice, it's a script; if it's a script, it's versioned
• Comfort working across Linux, cloud services, and networked systems
• Scripting proficiency in Python, Bash, or equivalent
• Self-directed and high-ownership — you close the ticket, you don't wait to be asked twice
• Bonus: experience with robotics environments, ROS, or edge/embedded systems

Why Join Polymath Robotics?

• Mission that matters: The vehicles we automate operate in places no human should have to be — e.g., steel mills with molten slag, fertilizer plants thick with chemical dust etc. Removing people from such unsafe environments is our mission.
• Collaborative environment: Work alongside a tight-knit group of ~20 people, each expert in their field, 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, and your work can be shareable and publishable wherever 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.
