On a day-to-day basis, a Customer Success Engineer at Harness drives customer enablement and technical resolution. Your primary focus is ensuring that customers can seamlessly deploy their software using the Harness platform.

You will spend your time partnering with enterprise engineering teams to architect robust continuous delivery pipelines. This involves understanding their existing toolchains—such as Jenkins, GitLab, Terraform, and various cloud services—and helping them integrate these systems with Harness. When technical hurdles arise, you will dive deep into logs, configuration files, and network traces to find rapid resolutions.

Collaboration is a cornerstone of this role. You will work closely with Harness Account Managers, Solutions Architects, and Product Engineers. When you identify recurring technical challenges or product gaps, you will write detailed bug reports and feature specifications, ensuring the voice of the customer directly shapes the future of the Harness platform.

To be competitive for the Customer Success Engineer role at Harness, you should possess a strong blend of systems engineering experience and customer-facing capabilities.

• Must-have skills – Strong hands-on experience with Kubernetes and Docker. Solid understanding of CI/CD concepts and tools (e.g., Jenkins, GitLab, ArgoCD). Proficiency in basic scripting (Bash, Python, or Shell) to automate tasks and parse data. Excellent verbal and written English communication skills.
• Nice-to-have skills – Experience with cloud platforms (AWS, GCP, or Azure). Familiarity with infrastructure-as-code tools like Terraform. Prior experience working in a dedicated support engineering or customer-facing technical role within a SaaS or enterprise software company.

Typically, successful candidates have 3+ years of experience in roles such as DevOps Engineering, Systems Administration, Technical Support Engineering, or Solutions Architecture.
