Platform Engineer – Agentic AI & Harness Engineering

About this role

Who We Are At Kyndryl, we run and reimagine the mission-critical technology systems that drive advantage for the world’s leading businesses. We are at the heart of progress; with proven expertise and a continuous flow of AI-powered insight, enabling smarter decisions, faster innovation, and a lasting competitive edge. For our people—Kyndryls—that means doing purposeful work that powers human progress

Join us and experience a flexible, supportive environment where your well-being is prioritized and your potential can thrive. The Role We are hiring a Platform Engineer to build the internal agent harness: the runtime, orchestration and guardrails that turn foundation models into AI agents doing reliable, governed work at scale. This is harness engineering as a discipline, not a vendor's product

You build the outer harness around the model, the configuration, tool integration, evaluation and oversight that make agentic productivity real across engineering, infrastructure and operations. You will treat this harness as a product whose users are the teams building and running agents. The goal is agentic productivity that can be measured: agents that ship useful work, safely, and keep working when the underlying models change

What you will do Design and build the agent harness: runtime, orchestration, tool and MCP integration, context and memory, evaluation, guardrails and observability. Build golden paths and reusable patterns so teams ship agents that are reliable, governed and measurable, instead of one-off scripts. Define the oversight model: policy-as-code, human-in-the-loop checkpoints, loop and failure detection, evaluation harnesses, and cost control

Integrate agents with the systems they act on: CI/CD, infrastructure, cloud services, observability and ticketing, through APIs and MCP. Make agentic productivity measurable: define what productive means for each use case, instrument it, and run the harness on that data. Keep the harness model-agnostic and versioned
