Harness brings AI and automation to this outer loop, turning complex, time-consuming workflows into streamlined processes at massive global scale.
The platform includes industry leading products in CI/CD, Feature Flags, Cloud Cost Management, Service Reliability, Chaos Engineering, Software Engineering Insights, Internal Developer Experience, and API discovery, observability, governance, and runtime protection. Over the past year, Harness powered 128M deployments, 81M builds, 1.2T API calls protected, and $1.9B in cloud spend optimized, helping customers like United Airlines and Choice Hotels accelerate releases by up to 75% and achieve 10x DevOps efficiency. With employees in over 25 countries, Harness is shaping the future of AI-driven software delivery — and we’re looking for exceptional talent to help us move even faster.

Position Summary:

Harness is a high-growth company disrupting the software delivery market. Our mission is to enable the world's 30 million software developers to deliver code to their users reliably, efficiently, securely, and quickly. By increasing our customers' pace of innovation and improving the developer experience, we're building the future of intelligent software delivery. As a Senior Developer Productivity Engineer, you will be key to improving the velocity of our own world-class engineering team.

We are looking for a hands-on Senior Developer Productivity Engineer with 5-8 years of experience who is driven by a deep desire to make people successful in their developer roles. This role requires technical mastery of CI/CD and build systems, combined with a servant leadership approach to product engineering. You will be a key driver in adopting cutting-edge technologies, including Large Language Models (LLMs), to revolutionize our internal development processes.
About the role

Design, develop, implement, and maintain core developer tools and services (e.g., code coverage, code review, unit/contract test framework, artifact management) to create a seamless and low-friction Developer Experience (Dev Ex).
Drive research, experimentation, and productionization of Large Language Models (LLMs) and AI tools to augment developer workflows, focusing on areas like code generation, intelligent testing, auto-documentation, and automated troubleshooting to dramatically improve efficiency and productivity.
Lead the architecture and continuous improvement of our internal CI/CD pipelines (leveraging the Harness Platform) to ensure fast, reliable, and secure deployments.
Identify and aggressively eliminate performance bottlenecks in large-scale build and test systems, implementing advanced caching, parallelization, and build graph optimizations to significantly reduce cycle time.
Implement and manage tooling for code coverage and static/dynamic analysis, seamlessly integrating them into the pipeline and code review process.
Partner with feature teams, acting as an empathetic consultant and platform advocate. You measure your success by the success of your internal customers (our developers), providing guidance, reducing their toil, and ensuring they have the best environment to ship code.
Define, track, and report on key developer productivity and platform health metrics (e.g., DORA metrics). Implement robust monitoring, logging, and tracing to provide deep visibility into developer platform reliability and performance.

About you

5-8 years of professional software engineering experience, with at least 3 years focused on Developer Productivity, DevOps, or Product Engineering.
Strong proficiency in at least one major language used for backend development and tooling (e.g., Go, Python, Java) and strong shell scripting skills.
Deep, hands-on experience designing and operating Continuous Integration and Continuous Delivery systems at scale. Practical knowledge of the Harness Platform is a significant plus.
Extensive experience with build tools (Maven, Gradle, Bazel, or similar) and a proven track record of successfully implementing complex build tuning and optimization strategies.
Solid working knowledge of Docker and Kubernetes for managing build environments and application deployments
Demonstrated commitment to Servant Leadership principles, prioritizing the needs of development teams and passionate about reducing developer toil.
