Apply on Jobicy## Description Harness is the AI Software Delivery Platform company, led by technologist and entrepreneur Jyoti Bansal (founder of App Dynamics, 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 Dev Ops 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 Harness Software Engineering Insights (SEI) is where engineering meets engineering intelligence. As part of this team, you’ll work on a deeply technical product that connects to 40+ developer tools like Jira and Git Hub, processes millions of events, and turns raw SDLC data into actionable metrics.

This is a product that engineers build for engineers, where you’ll see your work directly impact how thousands of developers build software. Expect challenges in data modeling, systems design, developer UX, and secure cloud integrations — all to help engineers and leaders build faster, better, and smarter.
