Job description

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 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.

About The Role

Product Security is responsible for ensuring the continuous security of Harness customer‑facing products and internal tools. The team is focused on proactively discovering security weaknesses, driving and advising risk remediation, building a paved road for developers to adopt secure development practices, and developing partnerships with engineering and product teams to accelerate the release of software with security by design.

The Senior Product Security Engineer is a highly skilled practitioner who drives hands‑on security work across the Harness platform. You will own technical security initiatives end‑to‑end, partner closely with engineering and product teams to identify and remediate vulnerabilities, and build tooling and processes that elevate the security bar across our development lifecycle. This role is for engineers who love to build, break, and secure complex systems.

What You Will Do

• Design and develop product security APIs, tools, and utilities for internal and external stakeholders.
• Conduct threat modeling and secure design reviews for application backend services and business integrations.
• Perform advanced penetration tests and adversarial attack simulations against Harness modules, APIs, and codebase using industry‑standard frameworks.
• Lead manual and automated code review efforts to discover vulnerabilities, weaknesses, and anti‑patterns in the Harness platform.
• Implement and operate security tooling including SAST, DAST, and SCA, and integrate these into CI/CD pipelines.
• Consult and advise developers and Product Managers on security standards, vulnerability remediation, and security architecture.
• Assess risks and trade‑offs, and propose solutions for product security features such as authentication and authorization.
• Participate in the creation, review, and implementation of technical security standards across global engineering teams.
• Use the Harness platform to integrate security processes like vulnerability management into the SDLC.
• Collaborate cross‑functionally with Engineering and Product to accelerate the release of software with security by design.

About You

• BS in Computer Science or a related degree.
• 5+ years of relevant industry experience with a strong security focus.
• Solid experience with DevSecOps practices and secure SDLC methodologies.
• Good working knowledge of cyber security frameworks including OWASP, SANS, NIST, and CIS.
• Ability to describe software supply chain risks and Secure SDLC best practices.
• Experience with public or private cloud environments such as K8s, AWS, GCP, or Azure.
• Professional knowledge of enterprise applications, API development, and modern software delivery processes.
• Previous experience in a cloud‑native environment.
• Proficiency in Java or a comparable language and object‑oriented programming methodology.
• Hands‑on experience with security testing tools and vulnerability management workflows.
