Job description

Harness is the AI Software Delivery Platform company, led by technologist and entrepreneur Jyoti Bansal (founder of AppDynamics, acquired by Cisco for $3.7B). Harness has raised approximately $570M in funding and is valued at $5.5B, backed by leading investors including Goldman Sachs, Menlo Ventures, IVP, Unusual Ventures, Citi Ventures, and more. As AI accelerates code creation, the real bottleneck has shifted to everything after the code – testing, deployments, application security, reliability, compliance, and cost optimization. Harness brings AI and automation to this “outer loop,” helping teams ship software faster while maintaining security and governance throughout the entire software delivery lifecycle.

Powered by Harness AI and the Software Delivery Knowledge Graph, the Harness Platform applies deep context and intelligent automation across the software delivery lifecycle with governance and policy-driven controls embedded throughout the platform.

Over the past year, Harness powered over 185M deployments, 82M builds, 18T flag evaluations, 8M security scans, 9.1B optimized tests, 3T protected API calls, and helped manage $2.8B in cloud spend — enabling customers like United Airlines, Morningstar, and Choice Hotels to accelerate releases by up to 75%, reduce cloud costs by up to 60%, and achieve 10x DevOps efficiency.

With a global team across 26 offices and 27 countries, Harness is shaping the future of AI software delivery — and we’re looking for exceptional talent to help us move even faster.

Position Summary

Reporting to the Director of IT Infrastructure, the Senior IT Systems Administrator plays a critical role in owning, scaling, and securing Harness’ corporate IT environment. This is a hands-on, senior individual contributor role focused on identity, SaaS platforms, device management, automation, and security in a fast-growing, global company.

This position is ideal for someone who has already operated at scale, is comfortable owning systems end-to-end, and thrives in environments where automation, security, and user experience matter.

Operational Excellence

Lead and execute IT projects from design through delivery
Provide Tier-3 level troubleshooting and escalation support
Create and maintain high-quality documentation, runbooks, and knowledge base articles
Participate in a rotating on-call schedule
Ability to travel between company offices on an as-needed basis to support infrastructure projects, deployments, and on-site initiatives, including office buildouts, technology setups, and the resolution of complex on-site issues
Perform other duties as assigned, consistent with the role
