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 14 offices and 25 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 At Harness, design quality and innovation matters. We’re looking for a UI-focused Product Designer who sets a high bar for visual excellence, polish, and consistency across complex product surfaces. This role is for designers who care deeply about craft — designers who sweat the details, elevate interaction quality, and turn sophisticated technical workflows into clear, confident, and beautiful product experiences.
You’ll help define the future of Harness’ developer-facing products by shaping how our platform looks, feels, and behaves at scale. You are opinionated, design-driven, and skilled at transforming complexity into clarity. You’ve shipped enterprise software before, understand the rigor required for large systems, and know how to maintain visual quality across multiple releases.
While this role partners closely with UX, Product, and Engineering, the center of gravity is UI design: layout, hierarchy, interaction patterns, design systems, motion, and the overall level of polish that signals trust to enterprise customers
